摘要
110 kV内桥接线变电站普遍采用进线备自投,来进一步保证系统的安全、稳定运行及提高系统供电可靠性。对110 kV内桥接线进线备自投在现场应用中与主变保护、进线保护的配合问题进行了分析,并针对这些问题提出了改进措施,该改进措施能够解决生产和设计过程中遇到的技术问题。
Incoming line back-up self-switching equipment is universally applied in 110 kV substation with internal bridge connection for further ensuring the safety, stable operation ＆ improving reliability of system. The coordination of above equipment with main transformer protection and incoming line protection is analyzed, and improvement measures are proposed to solve the encountered problems.
