Comparison And Study

Aim to solve the harmonic problems in microgrid, parallel operation of APFs (active power filter) is studied. With the comparison and study of many strategies about current sharing and parallel operation, a new parallel method and control strategy of APF is proposed in microgrid. And the implementation method of parallel operation and current sharing is studied. Finally, both the simulation and experimental results demonstrates that the method is correct and effective, and the good dynamic performance and compensation effect have been proved.

Power Quality Improvement

A new control strategy for active power filters is proposed, modeled and implemented in order to improve the power quality of a line commutated converter High voltage DC link. The ability of reactive power and harmonics reductions are generally met by using passive and active power filters. In this paper, modified active power filter with a modified harmonics pulse width modulation algorithm is used to minimize the source harmonics and force the AC supply current to be in the same phase with AC voltage source at both sending and receiving sides of a line commutated converter high voltage DC link. Therefore, it is considered as power factor corrector and harmonics eliminator with random variations in the load current. The modified harmonics pulse width modulation algorithm is applicable for active power filter based on a three-phase five-level and seven-level cascaded H-bridge voltage source inverter. Simulation results show that the suggested modified multilevel active power filters improve total harmonics distortion of both voltage and current with almost unity effective power factor at both AC sides of high voltage DC link. Therefore, modified active power filter is an effective tool for power quality improvement and preferable for line commutated converter high voltage DC link at different load conditions.
