| Abstract: | Automatic reactive power compensation is important part in research of automation for distributed power system. At present, the controller for reactive power compensation is abroad applied which be developed with technology of embedded system. This paper introduces a distributed Transformer Terminal Unit(TTU) base on MSP430F449 singlechip produced by TI corporation, which has function of reactive power compensation control and apply to low voltage power system(0.4kV).Former TTU has only function of monitoring distributed transformer, but after being reformed on hardware and software, it is realized for TTU to has function of reactive power compensation control. In article, it is discussed include main hardware configuration, theory, mothed and principle for thyristor switched capacitor and peculiarity. |
