A mathematical model for analysis of energy characteristics of electric power generation system consisting of a synchronous generator with excitation from permanent magnets, the active rectifier and the voltage inverter with PWM is considered. Various algorithms to control the active rectifier and inverter for variable speed wind turbine shaft are analyzed. Analytical relations for the calculation of currents, voltages and power generation in the system are obtained. Recommendations on the choice of control algorithms and structural circuits of the generation electrical energy at a variable speed shaft WT are given.
