Fault Analysis of NO.3 and NO.4 Generator Sets Shut Down on "7.24" in Jiujiang Power Plant

According to the operational aspect and various viewing signals on electric consol incentralized control room of Jiujiang Steampower Plant NO.3 and No.4 Units, the process of NO.3 and NO.4 Units shut-down in success are seriously investigated and discussed and analyzed. In the end, we found out the real reason of this fault. Shortage existed in the design of field regulators KKL-3. In order to avoid this kind of fault happening again, effective countermea-sures are finished. We hope to supply reference for generator sets of the same kind fitted up with field regulators KKL-3 and avoid this fault happening on them.
