摘要

The paper presents an induction generator connected to the power grid using the AC/DC/AC converter and LCL coupling filter.In the converter,both from the generator and the power grid side,three-level inverters were used.The algorithm realizing pulse width modulation(PWM) in inverters has been simplified to the maximum.Control of the induction generator was based on the indirect field oriented control(IFOC) method.At the same time,voltage control has been used for this solution.The MPPT algorithm has been extended to the variable pitch range of the wind turbine blades.The active voltage balancing circuit has been used in the inverter DC voltage circuit.Synchronization of control from the power grid side is ensured by the use of a PLL loop with the system of preliminary suppression of undesired harmonics(CDSC).
