Abstract
In this paper
a kind of magnetic valve controlled reactor and APF comprehensive compensa-tion system is proposed
which can solve such problems as slow dynamic response speed and highharmonic contents. The topological structure of the system is introduced
in which APF compensates loadharmonics and harmonics generated by MCR
the reactive power current is compensated by the MCRand
at the same time
during the dynamic response period of MCR
the DC current which is generatedby the capacitor at the DC side of APF is used as DC excitation source so to improve the dynamic responsespeed of MCR. It is shown by the simulation result that the comprehensive compensation system cancompensate effectively both reactive power and harmonic current of the load and
at the same time
solvethe problem of dynamic response of MCR.
