This paper describes the methods of Harmonic Elimination, with the development of power electronic equipment, harmonic pollution of power system is more and more serious traditional method for harmonic elimination and reactive power compensation is the LC power filter based on resonance principle, but this method can only eliminate the specified order harmonic, and probably cause parallel or series resonance with the power system. Due to the high controlling and quick response, active power filter has been paid more attention for eliminating harmonic with magnitude and phase varying. This paper discusses the main approaches for harmonic damping, proposes the study development of active power filter(APF), and gives some forecasting on the research of active power filter and hybrid active power filter.

Passive power filter (PF) has problems that source impedance may strongly affect the filtering characteristics and cause system resonance in power system applications. Hybrid active power filter (HAPF) can improve the performance of passive filter and realize harmonics restraint and reactive power compensation in big power situation. In this paper, the principle of HAPF is analyzed, the model of HAPF is established, and the simulation results are discussed.

Hybrid Active Power Filter

<p>The accuratedetermination of the load harmonic current is one of the important factors, it decides to effect of harmonic filtering and reactive power compensation for Hybrid Active Power Filter. The p-q harmonic detection method has been widely used in determining the harmonic currents of Hybrid Active Power Filter. However, when using this method, the dynamic response of Hybrid Active Power Filter in the transient period will have a large transient time and overshoot whenever the load changes abruptly. Therefore, in this paper an improved p-q harmonic current detection method based on fuzzy logic is proposed, which aims to reduce the overshoot and transient time in transient duration of Hybrid Active Power Filter. In order to compare the dynamic response of conventional and improved p-q harmonic detection methods, simulation results have demonstrated that: the proposed method has a shorter response time, the magnitude of the supply current in the transient time is smaller and the overshoot of the fundamental active and reactive power components is very small. This has a practical significance that contributes to the stability of the Hybrid Active Power Filter system</p>

A new hybrid active power filter (NHAPF) and its corresponding controlling method are proposed in the paper, which can be applied in high voltage system. The topology structure of NHAPF is given and its compensating principle is described. The corresponding controlling method is a power direct control, which need not the lower pass filter and improve the performance of detecting precision and velocity. Simulating results show that the feasibility and validity of the compensated system. Harmonic currents and reactive power are compensated well.
