舰船电力系统非同期合闸保护装置设计

Design of Asynchronous Breaker Closing Equipment of Warship Power System

本文提出了一种在并网开关源头直接消除非同期并网事故的方案。基本思路是装置准确检测和判断待并机组间的电压差、频差和相角关系,简洁可靠实现并网开关非同期合闸的无源保护,保证电控台遥操和就地操作开关实现机组并网的安全。动态模拟试验证明装置原理设计正确、工作可靠,在舰船电力系统中具有广阔应用前景。

A scheme that is used to cancel asynchronous breaker closing fault in interconnected switch is proposed. The voltage difference, frequency difference and phase-angle relationship between generators are detected and judged correctly to realize reliably asynchronous breaker closing source-free protection, thus the safty of generators interconnected by electrical console desk remote operation and local operation can be guaranteed. The asynchronous breaker closing equipment designed is proved principle correct and work reliable by dynamic analog test, which can be applied widely in warship power system.
