Abstract: Combining with the bypass logic action behavior of the Mitsubishi gassteam combined cycle unit, the problem of the highpressure bypass governor valve of the M701F unit, which could not be closed normally during the unit startup process, was expounded. The problems were analyzed. The solution was given, and similar trouble was avoided.
