Compensation with Hybrid Active Power Filter in an Industrial Plant

Parallel Hybrid Active Power Filter for Static Reactive Power and Harmonics Compensation with Sogi-pll

In this paper, according to the lack of relevant studies based on reactive power compensation, the control method related to this subject has been investigated and applied to the Parallel Hybrid Active Power Filter (P-HAPF). Firstly, the dq base control algorithm is applied for harmonic compensation. Then, the reactive power compensation control which is supplied by active filter of hybrid acti...

PID-Fuzzy Control Method with Time Delay Compensation for Hybrid Active Power Filter with Injection Circuit

Due to inherent time delays in the control system of Hybrid Active Power Filter with Injection Circuit (IHAPF) and the load harmonic currents changes rapidly and dramatically. In order to eliminate these harmonic currents, an IHAPF to be used must be able to respond quickly following variable of the harmonic currents. So, this paper proposes a PID-fuzzy control method with time-delay compensati...

Current Harmonic Compensation and Power Factor Improvement by Hybrid Shunt Active Power Filter

In this paper the current harmonic can be compensated by using the Shunt Active Power Filter, Passive Power Filter and the combination of both. The system has the function of voltage stability, and harmonic suppression. The reference current can be calculated by dq transformation. An improved generalized integrator control was proposed to improve the performance of APF. The simulation results o...
