Improvement of modern wind turbines (VU) of low power needs, accordingly, improvement of systems of regulation of speed and capacity. One of such simple and reliable regulators, which have become widespread in the systems of regulation of wind turbines, are centrifugal regulators. The new theoretical positions proposed in a series of works, which serve to improve the methods of calculating the centrifugal regulators of rotors of wind turbines, require an experimental verification. Analyzing the main methods of research of wind turbines with centrifugal regulators, it is necessary to note the following. Conducting experimental studies in the field requires a well-equipped polygon and a significant amount of time to conduct research to the extent necessary, provided there are sufficient wind speeds. Conducting research in an aerodynamic tube requires significant financial costs, and it is difficult to simulate dynamic tests with a sharp change in air flow technically. Similar problems, albeit to a lesser extent, arise in the testing of the transport of wind turbines by car. Taking into account the above-mentioned reasons, it was decided at the Renewable Energy Institute to develop and manufacture its own stand for experimental research on centrifugal and other types of regulators of wind turbine rotors. This stand includes an aeromechanical part, an experimental rotor with a centrifugal regulator and a block of measurements and loads, which allows to investigate the operation of the regulator at its various parameters with static and dynamic loads. The proposed method of conducting research at the stand includes the study of the influence of frictional forces in the mechanism of the regulator, the determination of static characteristics of the rotor of the wind turbine with a centrifugal regulator during floodgate and anti-flueler regulation with the change: the moment of the load on the rotor; The values of the initial tension of the regulation spring; The moment of inertia of centrifugal weights; The angle of installation of centrifugal weights and the determination of rotor rotational deviations at external disturbances, namely, with a sudden increase and a sudden decrease in rotor load and sudden change in wind speed.
