| The meaning of low-voltage reactive power compensation and the actuality of reactive power compensation device are discussed in this thesis. The characteristics of three-switched execution organ of var compensation (thyristor, complex switch and contact implement) and its application field are compared. With Motorola DSP56F807 a reactive-power compensation controller is designed. It also has the function of distribution power monitor. It can compensate reactive power locally, measure information of electric power, but also can send information, control compensation capacitor telecontrolly and configure parameter by TC35 that is a mobile SMS (Short Messages) module TC35 of Siemens Co. It is characteriazed by simple construction, reliability service. The thesis analyzed the hardware and software of controller in detail. The hardware principal, circuit diagram and software frame drawing of controller were expounded. The integrated control mode is adopted, that can improve power quality furthest. |
