The object of study is electromechanical processes in PS with different types of generators when operating offline and grid connected. The scientific novelty. A dynamic simulation model of an electromechanical system with a transformer-semiconductor energy converter, containing a step-up DC/DC converter on the wind turbine side and an inverter-transformer unit, has been developed, allowing the creation of simulation models of wind farms with wind turbines operating in parallel in a DC circuit to a centralized voltage converter and the assessment of energy performance and efficiency of algorithms for regulating the speed of wind turbines, voltage and reactive power. It has been established using mathematical modeling tools that the proposed principles of multi-level voltage stabilization of an autonomous asynchronous generator with a multi-module semiconductor voltage converter in the stator circuits ensure the absence of mutual influence of voltage regulators of individual modules, stabilization of the generator voltage without static error and a step-decreasing nature of the external characteristic of the autonomous power source acceptable to consumers. The practical novelty The proposed structure of a transformer-semiconductor energy converter for wind turbines operating in parallel is of practical novelty, in which, instead of matching low-frequency power transformers at the output of the wind turbines, DC/DC boost converters with an internal high-frequency alternating current link are used, which allows improving the weight and Product Description popup.authors Dzhura Oleksandr V.
