基于Handel-C的电容器组投切控制设计

Design of Capacitor Group Switch Control Based on Handel-C

在电力传输过程中,由于大量无功功率的存在,不可避免地导致线路损耗的增加,给用电设备安全运行带来了隐患。因此,改善和提高电网运行质量,必须对电网进行无功功率补偿。采用电容器组进行无功功率补偿,提出一种将循环投切和编码投切控制方式结合起来的投切控制策略。这种控制策略不仅大大提高无功功率补偿精度,而且可以延长整体电容器组的使用寿命。整个软件系统采用Handel-C语言进行编程,并最终在FPGA上实现电容器组投切控制功能。

A mass of reactive power exists in electric power transmission course, accordingly the wasting of circuitry increases and the electrical equipment safe have brought hidden trouble. Therefore, improving and raising the operation quality of electrical network must compensate the reactive power. In the design, compensating reactive power adopts capacitor group. A kind of control strategy has been introduced that provided with both circulatory and coding control function. This kind of control strategy not only can raise consumedly the reactive power compensation precision, but also can prolong the service life of overall capacitor group. The software system adopts control strategy with Handel - C language programming and has been implemented all right in the FPGA, namely implementing the capacitor group switch control function.
