Industrial and agricultural production as well as the general public because the demand for is much larger, the electricity grids integrated-transportation network multiple transformer output to the end-use equipment bring great difficulties and many other different failures, resulting in a lot of energy wasted . This article is mainly to use the thyristor controllable series compensated (short for TCSC) for power during transmission of some compensation to make the system voltage stabilized and improved, combining with active power filter (short for APF) will suppress and filter out a series of primary and secondary synchronization harmonic interference etc. not only improve the effectiveness and utilization of electrical energy, but also purify the electricity grid environment. By the simulation results show that the power to improve the stability and quality are very good results.
