摘要
介绍了保定热电厂厂区变接线方式,分析了备用电源自投装置投运的三种方式,针对微机型备用电源自投装置的缺陷提出了利用发电厂DCS分散控制系统冗余资源实现备用电源自投装置的功能,使得备电自投系统获得DCS级别的系统可靠性,并进行了试验验证。
This paper introduces connection change of Baoding power plant factory, analysis three method of backup power self vote device. For microprocessor-based backup power self vote device defects, using power plant DCS to achieve the function of backup power self vote device. So the backup power self vote device access the reliability of DCS, and carry out the test verification.
