摘要:

基于双机并联冗余的不停电电源系统(UPS)结构在大型火力发电厂应用较多,运行可靠性高。由于其输出并联的特点,当故障机器检修结束后并列恢复时,采用不同的操作方式对UPS母线电源质量的影响差异较大。对某发电厂在并机操作过程中UPS母线电源产生波动造成空气预热器跳闸事件进行分析,通过PMDR-200型便携式故障数据记录仪对各种并机操作产生的不同效果进行分析、对比,找出了最佳操作方案,提升了运行人员的操作水平。

Abstract:

Based on twogenerator parallelrunning redundant uninterrupted power supply (UPS)structure applied in large thermal power plant is more, higher reliability. Due to the feature of its output in parallel, when the fault after the machine maintenance and recovery, adopt different ways of operation on the quality of the UPS power bus. In a power plant in weaver UPS bus power fluctuations in the process of operation caused by the air preheater, tripping events through PMDR200 portable failure data recorder for a variety of weaver has the effect of different analysis, comparison, find out the optimum operation scheme, improved the level of operational personnel.
