摘　　要：广州换流站原来以相控整流装置为核心的直流电源系统存在设备陈旧,难以提供合格、可靠的直流电源,且不能对蓄电池进行自动监视、维护,不能实现数字化的集中监视和控制等问题。文章分析、比较了直流电源系统中应用的相控整流装置和高频开关装置的优缺点;结合高频开关电源装置应用,设计了能实现集中监控的换流站直流电源系统并予实施。实践表明,该系统各项运行指标优越,维护工作量少,实现了直流电源系统的数字化监视、控制。The former DC power supply system with phase control converters is too old to supply regular and reliable DC power for the equipments,and also can not realize auto monitoring and maintenance functions of batteries,furthermore no digital centralized monitoring and control functions are furnished.The paper analyses relatively advantages and disadvantages of phase control converter and high frequency switch used in DC power supply systems,and accomplishes the design of converter station DC power supply system with centralized monitoring function. The finished system has excellent operating indexs and fewer maintenance work. The digital centralized monitoring and control functions are realized.
