Abstract With the rapid development of the industrial technology, various industries, especially high-tech industries，the power quality has become increasingly demanding. The research on reactive power compensation is becoming increasingly important. Static synchronous compensator and TSC application in the power system is widely used. This paper presented a STATCOM+TSC hybrid var compensation system, using STATCOM’s smooth and fast regulation performance combined with TSC’s simple structure, low cost. It can not only guarantee the overall dynamic performance, but also reduces the overall cost. It can meet the actual needs. The paper introduced the theory and structure of the STATCOM unit and the TSC unit. Based on this，a coordinated control strategy for the STATCOM+TSC hybrid var compensation system has been given. And the main circuit components for selection according to certain design principles. On this basis, designed to control chip TMS320F2812 DSP chip hardware control system compensation device, and the software part has made the corresponding presentation.
