摘　　要：现有的有源电力滤波器(Active Power Filter,APF)存在数据存储量小、历史数据少、远程监控能力差等问题,因此,需要有效地技术手段来解决这些问题。在230 M无线数传电台组网的电力负荷管理系统基础上,提出在有源电力滤波器的控制系统中增加无线调制解调模块,通过DSP实现数字化的前向纠错算法,构建了可靠的无线远程监控系统。在无线数传电台组网的基础上,有源电力滤波器配合上位机的电力能效测评系统软件,实现了电力能效监测、无人值守运行、远程实时监控、数据动态显示、故障报警和历史数据查询等功能。实验证明,该方法可以有效地解决无线通信中信噪干扰和信号衰落问题,具有很好的检错纠错能力和较高的数据传输效率,从而对有源电力滤波器进行有效地监控,提高了供电系统的安全性能和管理水平。There are some problems existing in present active power filter, such as the shortage of data memory space, the lacking of history data and poor in remote monitoring capability. Therefore, effeetive technical means need to be put forward to solve these prob- lems. Based on the 230M wireless digital radio network of Power Load Management System, this paper proposed to add a wireless mo- dem module in active power filter, implemented a digitized forward error correction algorithm through DSP, and constructed a reliable wireless remote monitoring system. On the basis of wireless data radio, cooperated with power efficiency evaluation system software on PC, the active power filter implemented power efficiency detection, unattended operation, remote real - time monitoring, dynamic data display, fault alarm and historical data query etc. Experiments proved that this method can effectively solve the problems of wireless communication signal- to- noise ratio （SNR） interference and signal fading, has a good error detection and correction capability and higher data transmission efficiency, and thus effectively monitors APF to improve the safety performance and management level for the power supply system.
