电力电源是电力系统中的重要设备,广泛应用于发电厂、变电站以及通信电源中,是保证自动控制与保护、动力、仪器仪表、信号、通信、事故照明等的核心,其性能和质量直接关系到电网的稳定运行和设备安全。传统的电力电源集中监控系统主要采用单片机来实现对各信号采集、控制、通信等,而目前应用越来越广泛的则是采用 DSP 控制器的新型集中监控系统。与单片机相比,DSP 控制器具有更好的处理性能,更低功耗,更高的外设集成度,实时控制能力更强,能够实时检测直流充电模块、蓄电池的运行状态,记录和处理相关数据,使远程机能实现对电力电源设备的遥信、遥测、遥控、遥调,从而有利于用计算机监控系统代替人工控制技术,满足电站自动化的要求,实现无人值守变电站,提高电网的综合效率和可行性。
Power supply is an important equipment in power system. It is widely used in power plants, substations and communication power supply. It is the core of guaranteeing automatic control and protection, power, instrumentation, signal, communication, accident lighting and so on. Its performance and quality are directly related To the stable operation of the power grid and equipment safety. The traditional centralized monitoring system for power supply mainly adopts single-chip microcomputer to realize the signal acquisition, control and communication, etc. At present, more and more applications are the new centralized monitoring system using DSP controller. Compared with the single-chip microcomputer, DSP controller has better processing performance, lower power consumption, higher peripheral integration, real-time control capability, real-time detection of DC charging module, the battery operating status, recording and processing related Data to enable the remote function to realize remote signaling, telemetry, remote control and remote control of the power supply equipment, which is beneficial to replace the manual control technology with the computer monitoring system to meet the requirements of the automation of the power station, to realize the unmanned substation and improve the comprehensive efficiency of the power grid And feasibility.
