Abstract: In a hydropower station, the reliability of the auxiliary power supply must be ensured for keeping the normal operation of the power station. The No.7 auxiliary transformer of Jingpohu Hydropower Plant underground power station in cave entrance is act as important power supply of network controlled switching station. The rationality and scientific of its connection mode are very important to safety and stable operation of Jingpohu underground hydropower station. The defects of original connection mode were analyzed, and targeted reformation and regulation were carried out. The reformation brought obvious economical and social benefit.
