复杂的可编程逻辑器件在可控电抗器中的应用

The Applications of CPLD to Electrical Power System

分析了磁阀式可控电抗器的结构和工作原理，通过直流控制电流控制铁芯的饱和度来调节电抗器的投入容量，采用可控硅和复杂的可编程逻辑器件（ＣＰＬＤ）为其设计了控制装置，实现了电抗器容量的自动连续调节，具有响应速度快、可靠性高的特点，并在电网无功补偿中得到了较好的应用．

The structure and principle of magnetic valve variable reactor are describled in the paper.The compacity of reactor can be adjusted by controlling the magnetic saturation of the iron using DC controlled current. By employing variable reactor and CPLD, several automatic electrical power control systems and a reactive power compensation apparatus are well designed and implemented,which can adjust the campacity continuously with a prompt response and a good reliability.
