The successful implementation of parallel DC power technology in 110 kV Shikai Station means that the problems existing in the traditional series DC power system such as low battery pack reliability, old and new batteries can not be mixed, and can not be online full capacity core capacity have been successfully solved, and the power supply reliability and operation and maintenance efficiency of the station DC power system have been greatly improved. It will actively promote the promotion and application of mature DC power supply technology in Guangxi, and realize a big step forward in the digital construction process of station power supply. In the next step, Yulin Power Supply Bureau relies on scientific and technological means to develop new quality productivity according to local conditions. Taiang Energy will adhere to the demand orientation, pay attention to the grassroots effectiveness, optimize the system functions, and constantly polish the system plan, so as to contribute more to the safe and stable operation of the power grid and the construction of the energy Internet.
