Chain SVG (Static Var Generator) module test system, platform and method

The invention relates to a chain SVG (Static Var Generator) module test system, platform and method. The test system comprises the test platform and at least two SVG modules, wherein the test platform comprises a control circuit part and a main circuit part. The test system has a low voltage level, is easy to operate, and has small system loss; testing can be performed by twin trawling of two H bridges without simultaneous running of the H bridges of an entire chain SVG, and a large amount of reactive power is prevented from being exchanged with a power grid. 本发明涉及种链式SVG模块测试系统、平台及方法，测试系统包括测试平台和至少两个SVG模块，测试平台包括控制电路部分和主电路部分。该测试系统的电压等级低、操作简单，且系统损耗小，无需链式SVG整机H桥同时运行，只需两个H桥对拖运行，即可进行测试，并且不会与电网交换大量无功。
