Technical analysis and treatment for frequent tripping of the 32 MW turbine generator;

Through the comparison of the variable frequency start and the soft start of the squirrel cage AC asynchronous motor,the merits of former have been reflected,and the problems in use which should be paid attention to have been raised,and the solution of frequency-changer overflowing tripping operation by the frequency converter set of parameters for the improper in the electric drive system.

During its long-term operation, generator stator appears tripping operation.

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.
