Analysis of the control system of a wind plant connected to the ac network
(КПІ ім. Ігоря Сікорського, 2023) Nerubatskyi, V.; Hordiienko, D.
The dynamics of the development of alternative power sources over the past few decades are presented, which gives reason to talk about the trends in the further development of wind energy. An analysis of the structures and technical characteristics of wind generators is provided, namely, types of electric motors, power circuits of semiconductor converters that provide the generation of electrical energy to the general industrial electrical network. The issue of the possibility of operation of wind generators in wide wind ranges, the issue of emission of reactive power and higher harmonics of currents to the general industrial electrical network, as well as the issue of the efficiency of various structures of wind generators are considered. A wind turbine control system with an asynchronous generator is proposed. A study of transient control processes and energy compatibility of a full energy conversion wind turbine with a power supply network by simulation computer modeling in the Matlab / Simulink software environment is given. The obtained result indicates the possibility of operation of an asynchronous generator with a short-circuited rotor as part of a wind turbine, which makes it possible to provide power to the alternating current network at low wind speeds.
