K e y w o r d s: electrodynamics models, oil industry electric drives.
The application of the electrodynamic modeling technique is substantiated.
The methods of laboratory electrodynamic modeling (EDM) of any complicated
mechatronics systems are very effective. A computer guides the model and, at the
same time, processes feedback signals and analyzes results data in real time. The
thyristor converter is used for the considerable extension of the model’s electrome-
chanical characteristics frequency operating range. The modeling process is carried
out using industrial 3—5 kW small electrical machines, but it uses the real excitation
and control systems of the modeling powerful generators and motors.
Electromechanical systems of the oil and gas industries usually work under
harsh technical and climatic conditions which raise several demands and strict

requirements for the design of new mechanical, electrical and electronic equip-
ment. The most important here — a special mobile team, using helicopter, ship
or all-terrain track-type vehicles etc. can service thousands of pieces equipment
in these vast areas (Arctic, tundra, desert, sea jack-up derrick or island, etc.) only
once a year, rarely twice. Thus, the equipment which operates in these areas (far
away from technical service centers) demands an increase in their durability, re-
liability and vitality (higher than one year) during new technique designs.
Any unexpected or sudden stop during scientific experiments or technical
service of the equipment, even for 10—20 min, whatever the reason (mechani-
cal, electrical, electronic, etc), can bring long-term problems especially during
winter: frozen oil-well liquid in the output pipes, drilling mud in the derrick’s
manifolds or gas condensation in the gas pipeline etc. Such a breakdown will
cause the oil well to stop production for several months until the next summer
service. In the so-called «reach of sand» wells the stop usually causes the sand to
settles down through gravity and blocks turbine or sucker-rod oil pumps’ subter-
ranean reverse valves. This makes it difficult or impossible for an automatic
self-starting of pumps and results in a forced outage until the next service team
visit. The service team then has to make a complicated extra lift of the well ex-
ploitation pipe column and clean the sand from it.
Oil and gas wells are extremely hazardous and explosive installations: dur-
ing emergency cases there may be big leakages of gas or oil (a small emission of
gas and oil is always there). Therefore gas and oil field installations must not
have any sparking elements which can provoke fire or explosion at near 10 m
minimum around the well. All systems should have fire- and explosion- proof
motors, switches, control systems etc.
Further, the working conditions of boring and oil (gas) extraction equipment
are characterized by abrupt or cycling torque on the shafts. Some 70—80 % of
them are sophisticated systems, full of power electronics, several electrical ma-
chines, with their control systems and so on. For instance, there are electric
drives such as boring winches, or boring-mud and cement piston pumps, rotary
tables, electromagnetic brake mechanisms, centrifugal subterranean turbine
pumps and sucker-rod oil pumps. These specific working conditions produce an
unfavorable pulsation in the voltage supplying networks and lead to the prema-
ture wearing out of the electrical and electronic equipment.
There are some sophisticated scientific and technical problems for investi-
gation in order to optimize the technology of the above-mentioned installations
(being designed or existing) which have to serve under these severe, quasi-peri-
odical and quasi-shocking conditions of work. Natural field investigations of the
mechanisms are important, but, as mentioned above, putting into practice any of
these experiments is very complicated and risky work for these equipments and
also for the technical personnel. (Often the local oil board authority is contrary to
any scientific and technical field tests).

Recent results [1—6] indicate that PC mathematical modeling can help to
study the dynamics of such oil electromechanical equipment. Very often it leads
to difficult analysis due to a protracted real investigation time (several minutes),
the random complex manner of the voltage fluctuations across the motors and
yields a very rigorous character of the IM and SM full algebraic-differential non-
linear equations. Their solutions often do not give a strict homology between the
results obtained and the real processes [7].
Therefore, methods of electrodynamic modeling of the complicated electri-
cal drive systems are still very efficient. They are widely used both in the synthe-
sis, analysis and experimental trial of new multi-machine DC and AC drives,
their automatic control systems, and mechanisms such as diesel-generators,
pumps, winches, drilling table system etc.
The named analyses were conducted by means of the Special Computer-
Assisted Lab Electro-Dynamic Model (CALEDM). Standard industrial small (3
— 5 kW) machines, but real automatic excitations and technological control sys-
tems (if any) of the modeling systems are used in the model.
The computer controlled multifunctional electrodynamic model. The
computer controlled multifunctional electrodynamic model [2, 8, 9] was designed
for the investigation of oil (gas) industry equipment, especially for the controlled
multi-machine drives and generators on land and sea derrick platforms. The special
EDM for oil and gas industries electromechanical systems (Fig. 1) consists of:
1. Four electrical machines 3—5 kW (M1 — M4) — one AC synchronous
(or induction) and three DC — with real excitation and technological control
systems (TCS) of the modeling machines.
2. Three thyristor converters 500V and 50—100A (TC1 — TC3) and a TC-
controlled reactive power source for 3—5 kVAR.
3. Three two-way function switches and seven simple on (off) switches.
4. PC with A-D and D-A converters.
5. Measuring instruments: power transducers, tachometers (T), voltmeters
and ampermeters, oscilloscopes and record systems etc.
DC M4 (sometimes M2) operates as a load generator together with
resistances RL, R1 and TC3. The other electrical machines, including M2, work
as a modeling machines prototype. If necessary, TC1 together with M2 can be
used for a diesel system behavior simulation prototype in the model. TC1 and
components RU, LU, Sw9 and RLU are used to simulate pulsing or abrupt voltage
changes of the main supply (just after Sw1). The computer guides the model.
The thyristor rectifier TR3 of the CALEDM load imitation unit (separately
shown on Fig. 2) is used for the considerable extension of the model frequency
characteristics (compared to the load imitation via the DC generator exciting
coil). The method uses TR3 as variable contra-voltage (for both RG and RTR <<
<<RLD). When VTR > VG and is rising DC generator brings down its load — it can

be even shifted into motor regime (the investigating drive — into generator re-
gime). When VTR < VG and is decreasing there is an increasing motor regime of
the investigating drive.
It should be stressed here that CALEDM facilitates the study of higher and
lower inertial electrical machines rather than the model ones (using a negative or

sient processes on its eclectic drive. A special program can simulate the functional
characteristics of the long rod and then different working regimes can be modeled.
All these create similarity of the models processes and the real objects, extend
their functional opportunities and permit some parametric variations.
All the above mentioned features provide the model with universality and
allow the combining of the model elements for the simulation of the various in-
dustrial equipment mechatronic systems.
Practical applications. Synchronous or induction motor (SM or IM) simu-
lations under leap dynamic load and voltage cycle or abrupt fluctuation. This
study dealt with the problem of oil extraction field sucker-rod pumps (SRP) and
their specific conditions of work. It will be presented in detail step by step. The
other practical applications will be presented in brief — equipment connections
and results.
The following chain of the model elements was connected: 3 phase main,
switches S1 (on) and S2 (left position), M1— prototype drive model and M2 —
mechanical load simulating machines, S4 (in the middle position), S6 (on), Sw7
(left position), Sw8 (on), thyristor converter TC3 for the rapid-load simulation, 3
phases main. The load imitation control as well as the main experimental data in-
terpretation was made using a PC (see result on Fig. 3 — a real oscillogram). For
easy presentation a simplified (for this case) version of Figure1 diagram is
shown on Fig. 2.

tric drive and there are some opinions that a synchronous motor SM is more like
a «pendulum» than an induction motor IM: the dynamic stability of special
brushless synchronous motor (SBSM) under such voltage fluctuations might be
worse than IM dynamic stability. Therefore voltage fluctuation influences on IM
and SBSM stability were carefully studied and compared.
As mentioned, it is very difficult to use a digital computer for these studies
due to a protracted real investigation time (several minutes), the complex man-
ner of the voltage fluctuations across the machine terminals and mainly due to
the very stiff character of the IM and SBSM full model equations. Their solu-
tions often do not give a strict match between the results obtained and the real
processes.
Simplified computer-assisted lab electro-dynamic model (CALEDM). Ac-
tual field investigations of these electrical drives are possible and important.
However, due to the extremely hazardous character of oil fields, getting permis-
sion from any oil field administration is often extremely difficult. On the other
hand, the practicality of conducting these experiments in an oil field over wide
scales is very complicated and dangerous work for this expensive, sometimes
unique, equipment and a risky job for technical personnel. Thus, the methods of
electrodynamic modeling of an electromechanical system are still very efficient.
The simplified CALEDM (see Fig. 2) of SRP IM and SBSM drives study
under voltage fluctuations consist of: M — AC synchronous or induction motor;
DC GEN — DC generator of mechanical load imitation system; TR — thyris-
tor rectifier 500V / 100A; S — two ways functional switch; PC with A-D and
D-A converters; measuring instruments: power transducers, tachometer, volt-

meters and ampermeters, oscilloscopes, record systems and so on. There are two
types of studies due to S-switch position:
1. Switch S in up position. The DC generator and the thyristor rectifier TR
work together as a mechanical load imitation system. The thyristor rectifier TR
is used for the considerable extension (up to 10 Hz) frequency characteristics of
the mechanical load imitation system. The computer guides the model. Resis-
tance RL >> RG and RT. Here TR uses its variable voltage VTR to counter the gene-
rator voltage VG (EG). When VTR > VG and increasing, the DC generator brings
down its braking torque and can even enter in the motor regime, whereas the in-
vestigating drive M does vice versa — it goes from motor to generator regime.
When VTR < VG and decreasing, the DC generator increases its mechanical brak-
ing torque and drive M goes deeper and deeper into the motor regime.
2. Switch S in down position. Thyristor rectifier works on powerful resis-
tances R�V. Resistance RL and inductance LL help to simulate the voltage pulsa-
tion or abrupt voltage changes only on the terminals of the investigating motor.
A variable powerful DC current through R�V provides a variable powerful AC
current ITR through TR and line elements RL and LL leaving on them additional
variable voltage drop �V and simulates a voltage pulsation controlled by a com-
puter.

A special or personal computer (PC with A/D and D/A converters) governs
the load or voltage-pulsation simulation systems (see Fig. 2). Previously the
CALEDM was governed by a hybrid analog-digital computer and later by a PC.
The typical for SRP character drive load was produced by a special program us-
ing the mathematical equations of a mechanical load on the shaft (or power, or
current and so on). Similarly, study is done for voltage pulsation simulation on
the electrical machine terminals. Sometimes the mechanical load, current or
voltage of IM or SBSM are recorded on a tape during a visit to the oil field and
used in the CALEDM. The computer compares these signals with the appropri-
ate feedback signals from the electrodynamics model sensors (torque, voltage,
power, current or speed gauges). Built-in control software forces the model to
interpret the recorded signals and reconstruct them in the model elements. All
these factors provide an acceptable simulation of the actual dynamic processes
in a drive.

IM and SBSM Stability Analyses. The main reason for taking the coming
down approach of modeling the IM and SBSM stability problem is the follow-
ing: it is accepted as an evident assumption that the main influence on stability of
IM and SBSM (with constant exciting current) ought to exert:
1. The low frequency voltage harmonics equal or very close to the frequen-
cies of the shaft torque oscillations (0,05—0,5 Hz), especially the counter phase
to oscillations (�V = 180°);
2. The relatively high frequency harmonics (2—20 Hz), equal or closely
matching to the electro-mechanical resonance frequencies of IM or SBSM SRP
drive shaft systems.
Suppose the voltage oscillates between Vmax and Vmin with an angular velocity
�V and epoch angle �V according to:

, ( )[ cos ( )0 5 1 � � .
For the first (low frequency) case the voltage fluctuation �V was taken as
equal to � M (the frequency of the shaft torque oscillation) and �V =180° (for
four fixed voltage drop deviations �V V V� � �
max min
0; 5; 15 and 20 %). The
moment on the motor shaft was presented as:
M M M M tM� � � �

The motor was gradually loaded further up to the stability limit by in-
creasing only Mmax (Mmin = const 0,15
0,2). The last stable state value of
Mmax was taken as the sought limit result for the comparison of IM or SBSM sta-
bility factor.
First results. Based on various investigations [10, 11] it was found that on
average every 1 % of this low frequency counter phase voltage pulsation reduces
IM dynamic stability by about 1,75 — 2,5 % and SBSM by about 2 — 3 %.
The results show an almost equal dynamic stability for both IM and SBSM under
this low frequency voltage pulsation.
In the second (high frequency resonance) case the electromechanical reso-
nance frequencies of the IM and SBSM electric drives were approximated by the
model. Due to the relatively high value of these frequencies of voltage pulsation
(2 — 20 Hz, for IM even higher) it was evidently clear that the stability of the
IM and SBSM might be easily broken down during any maximum torque on
their shafts.

namic stability.

Second results. Similarly, based on various investigations it was found that,
on average every 1 % of this high (resonance) frequency voltage pulsation re-
duces the IM dynamic stability by approximately 1,5—2 % and for the SBSM by
2,1—2,4 %. Again, it is seen that the figures are almost the same and from a dy-
namic stability point of view both IM and SBSM are almost equal under this
high (resonance) frequency voltage pulsation. But the Fourier analysis of the
several waves of the real voltage fluctuation (see Fig. 2) has shown that the maxi-
mum amplitudes of these high frequency harmonics (higher than 2 Hz) are less
than 0,5 % of �U . Hence the total stability losses will be negligibly small for
both motors (less than 1 %).
The results obtained were used for the technical and economical substantia-
tion and application of a SBSM that has shown considerable reduction of energy
losses in power supply network, the rise of group dynamic stability, reliability of
the pumps motors, and even oil field ecological improvement [3].
Similar to resulted earlier, all other simulations systems of the oil field and
jack-up electric drives were conducted.
Controlled thyristor rectifier and direct current motor (TC-DCM) type of
variable speed drive simulation. The following chain of the model elements was
connected: three 3 phase main, S1 (on), S3 (on), TC1 — prototype model of in-
dustrial one, S4 (right position), M3 — prototype DC machine model and M4 —
mechanical load simulating machines, S7 (right position), TC3 — rapid-load
simulator, three phase main. This study dealt with a variable speed drive widely
used in oil industry for the design of land and sea (jack-up or sub) derrick plat-
forms. Similar to resulted earlier, the land or jack-up derrick winch block-
hook-tackle variable speed drive systems simulations were conducted.
The moment on the winch block-hook-tackle variable speed drive shaft was
presented as:

where Mw — moment on the winch; Ms — winch steady state moment; Ma — os-
cillation amplitude of winch system (longitudinal oscillation of the boring

The motor was also gradually loaded further up to the stability limit by in-
creasing only Ma. The last stable state value of Mmax was taken as the sought limit
result for the stability factor comparison of different types winch electric drives.

ing winch block-hook-tackle system drive TC+DCM after its rope slack cutback

Here it should be stressed that this computer-assisted electrodynamics
model provides the opportunity to study higher and lower inertial electrical
drives and also such equipment which are is under development or not available
among the model elements, for example, different types of electromagnetic
clutches [9], the modern electromagnetic brakes and so on. In such a case it is
possible to use a DCG + DCM system to model them. The so-called functional
characteristics of a clutch can be simulated by the help of synthesis in a computer
(using a special program) and then different working regimes can be modeled
and tested. All these create similarity of the processes in the models and the real
objects, extend their functional opportunities, and permit the wide variations of
their parameters.
The special or personal computer through A/D and D/A converters governs
the load and voltage-pulsation reproduction systems (see Fig. 2). The PC pro-
duces the driver loads typical for oil industry: in every case a special program
was used in accordance with the mathematical equations of the mechanical load
on the shaft (or power, or current and so on). Similarly, it is done for voltage pul-
sation simulation on terminals of the electrical machine (variable current of the
controlled TC1 provides the required voltage drop on RU and LU). Sometimes the
mechanical load or current and voltage magnetogrammes were recorded in the
oil field and used in this EDM (Fig. 6). The computer compares these signals

(moment, voltage, power, current, speed gauges etc.). The built-in computer
special control system software forces the model to follow up the given signals
(moment, power, current or voltage) and repeat them. All these permit an accept-
able imitation of the natural processes in any derrick electric drive.
Conclusions. Using electrical machines 3—5 kW, the model has carried out
simulations and investigations of complicated electromechanical systems (like der-
rick electrical drives) with a power up to 600 kW and shaft cycle moment pulsation
frequency from 0 to 10 Hz and for the network voltage deviation up to 30%. The
proposed computer-assisted electrodynamic model of controlled electric drives has
made it possible to reduce the number of necessary investigations under the oil field
harsh conditions of the first electric drives prototypes and obtain generalized results
of their static and dynamic stability in the following projects:
1. The substantiation of the partial replacement of IM by claw-pole bru-
shless SM for the subterranean sucker-rod pump and synthesis of its specific ex-
citation control system [1, 6, 8].
2. The comparison of different variable speed electric drives with cycle
shaft load on the power consumption smoothing effect for the oil field mecha-
nism [1, 3, 6].
3. The control systems design, probation and first start-up investigations of
the unique powerful controlled electric drives of the super-deep boring system
(BU-15,000) for 15 km, Saatli, Azerbaijan, and other projects [3, 7].
