Technical Electrodynamics| Summary: | Intensive introduction of the synchrophasor measurement of regime parameters of high-voltage electroenergy objects, above all things voltage phasor, needs research and evaluation of their measuring channels errors. The mathematical model of error of channel, which takes into account most factors which influence on its value, is offered. This model can be used, in particular, for the calculation of allowances to the results of measuring with the purpose of increase of their accuracy. Dependences of error components, caused by the communication line between the second loading and the voltage transformers, from a value, character and unsymmetry of loading are got. The example of application of model to the concrete channel is made. References 9, tables 1, figures 4. |
