摘要 谐波污染对于供电系统是一个很大的危害,特别在煤矿,冶炼厂中滤波系统更是具有举足轻重的地位。本文描述可编程控制器对原用的静态滤波系统进行改造。可编程控制器(PLC)作为一种可编程、无触点智能控制系统可根据系统中的谐波分量、功率因数等参数控制晶闸管导通,投入或退出电容与电抗器,动态消除电网中谐波分量,用低成本实现高性能补偿系统。 Harmonic is one of the great damage in the system of power supply, especially; it has very important degree in the coal mine or the smelt. Passive Power Filter is reconstructed by PLC in this thesis. PLC is a programmable and no-contact intelligent control system, according to the parameter, such as harmonic wave and power factor, this system controls thyristor open or close; runs or stops capacitances and reactance, dynamically dispel harmonic wave in the power grids. Using lower cost makes high capacity compensation system.
