摘要
在原理上对传统“九区图划分法”进行了改进 ,推导出考虑电容器组电压特性的控制量算式 ,对运行状态进行了更细致的划分 ,并提出相应的控制策略。在硬件方面 ,采用了80 C196 KC单片机系统及 ISP(In System Programm able)器件 ,具有友好的人机界面 ;在通信方面 ,采用了 CAN总线通信协议。经过数值仿真和模拟试验 ,验证了文中方法的正确性和优越性 ,具有实用价值。
In the development of a new integrated control set for voltage and reactive power in substation, some improvements for the traditional nine-zone diagram are performed. After the derivation of the formulas of the control variables, in which the relation between reactive power of capacitor and voltages is considered, the operating status is meticulously divided into more zones, and the corresponding control strategy is brought about. In the hardware of this set, the 80C196KC single chip microcomputer system and In System Programmable (ISP) device is adopted to provide a friendly interface; in the communication the CAN bus protocol is applied. The result of simulation tests shows that this method is correct and superior.
