微机型厂用电切换装置设计的若干技术

根据国内发电厂厂用电切换装置的现状，从分析厂用电切换的动态过程入手，提出了在设计过程中应以实际相角差而不是时间作为界定备用电源投入方式的标准，介绍了厂用电的“同期捕捉切换”方式和切换方式的“自适应”等若干技术，对提高厂用电切换装置的灵活性和厂用电切换成功率具有重要意义。

Several Design Techniques of Microcomputer-Based Switching Device for Auxiliary Power

Based on the current condition of auxiliary power switching devices in power plant, the dynamic switching process of auxiliary power is analyzed,and it is suggested that the real phase difference, in stead of time, should be taken as the criterion for spare power's putting into operation. The synchronous captive switching mode and the self adaptive switching mode for auxiliary power are introduced. They are important for improving the device sensitivity and successful switching rate of auxiliary power.
