III.Electrical problem troubleshooting in power plant
Problem Description: a coal mine`s 35KV H.T. switchgear OC protection tripped suddenly in He`nan Province, it caused sudden power lost of mine fan and endanger miner safety.
Auto-reclosing via switchgears` automatic reclosing function, through analysis, the reason is a set of 3000KW generator failure. Specific reason is: When the turbo-generator was running normally, exciting voltage lost suddenly, leading phase operation happened, the generator absorbed reactive power and lead to becoming motor running. Generator protection and power plant connecting line protection did not launch. After the generator absorbed a certain value of reactive power, the 35KV H.T. switchgear`s OC protection tripped.
Investigation: generator and power plant connecting line protection setting fixed value exceed the protection fixed value of 35KV switchgear side, it lead to nearby protection did not launch and override trip when generator failure.
