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。
The existing Active Power Filter (APF) has the problems of small data storage, less historical data and poor remote monitoring capability. Therefore, effective technical means are needed to solve these problems. Based on the power load management system of 230 M wireless data transmission network, a wireless modem module is proposed in the control system of active power filter. The digital forward error correction algorithm is implemented by DSP, and a reliable Wireless remote monitoring system. Based on the wireless data transmission network, the active power filter cooperates with the power efficiency evaluation system software of the host computer to realize the energy efficiency monitoring, unattended operation, remote real-time monitoring, data dynamic display, fault alarm and historical data Query and other functions. Experiments show that this method can effectively solve the problem of signal noise interference and signal fading in wireless communications, and has good error detection and correction capability and high data transmission efficiency, so that the active power filter can be effectively monitored and improved Power supply system safety performance and management level.
