Abstract：The fundamental voltage undertaken by the active part of injection type active power filter (ITAPF) is small because the injection circuit in the topology of ITAPF, so it is suitable for suppressing large-capacity harmonic in high voltage power grid. However, in the project engineering, because of the injection circuit, there are some problems such as the contradiction between harmonic voltage undertaken by fundamental resonance circuit should be small and injection ability of harmonic current should be good, the DC-voltage raising of ITAPF, the harmonic compensation precision is low because of phase delay of injection current caused by injection circuit. Based on sufficient analysis, this paper proposes some methods to solve these problems, including optimizing design of injection circuit, controlling DC-voltage adopting PWM rectifier, selective frequency phase compensation control. Simulation and project application results confirm the validity and feasibility of the methods proposed above.
