柴发机组带主变机组负载出现跳闸现象的分析

Analysis of the Switch off of Converter Set Load Fed by Diesel Generator

本文通过对柴油幅压发电机组在应急励磁状态下,双机并联运行突加主变流机组负载时,其主变流机组交直流自动开关跳闸现象进行了详细的分析;指出了在这种状态下其跳闸的必然性,并对其跳闸的过程进行了综合地分析,提出了在这种情况下的防范措施。

This article analyzes the reasons which result in switch off of the AC and DC breakers in the main converter set when the main converter set is suddenly connected to two parallel extent voltage diesel generators under emergency excitation. It points out that the breakers switch off under the above conditions is inevitable, and the course of switch off is synthetically analyzed in this paper. The prevention measure is also presented.
