Research on active power filter for distributed power system of high-speed generator driven by micro-turbine

Recently, more attention has been paid to the high-speed generator driven by micro-turbine due to its simple structure and high power density. In this paper, a method to reduce harmonic current in high-speed generator for a distributed power system is presented. Because no additional hardware is needed, the proposed method can be used for various power systems. The detecting and eliminating method of harmonic current components based on hysteresis control strategy of the active power filter using start-up inverter are discussed in detail. The simulation results show the feasibility of the proposed structure and the control strategy.
