Kharitonov Member. IEEE Novosibirsk State Technical University Rusia 1. Introduction For the high-power Wind Power Installation WPI with a variable speed wind turbine the system of transformation of mechanical energy into electric energy of the alternating current constructed under the scheme the synchronous generator with constant magnets -the active rectifier - the voltage inverter fig. 1 is perspective. Then the system is called the Wind Power Generation System - WPGS. O ứ var Permanent Magnet Synchronous Generator G I Active Rectifie R a c u Variable-Speed Section G Sa Section R .

WPGS of this type implements the full set of options required from the generation for high-power WPI namely this a generating mode at work on the nonlinear asymmetric and non-stationary loads electric starter startup mode of the wind turbine in-phase and parallel operation of an electric network and other WPI. In this paper we attempt to identify the main energy characteristics of system in sections SG SR SI ST SN fig. 1 when working on high-power electric network. Processes in the active rectifier and the voltage inverter are well studied at a constant frequency and voltage of the generator. The peculiarity of this study is the consideration of factors that arise when working within the system to generate WPI with a variable rotation speed of the wind turbine. These factors include changing the frequency and the voltage of the 24 Wind Power synchronous generator G as well as dependence of the generated power on shaft speed of the wind turbine. Presence in the system of the active rectifier R modifies the functional and .
