乌东德水电站厂用电系统设计介绍

Design of the Auxiliary Power System in Wudongde Hydropower Station

乌东德水电站是一座总装机容量为10 200 MW的大型电站,是"西电东送"的骨干电源之一,在电力系统中有重要的地位,对厂用电系统设计的要求很高。电站机组单机容量大,设备分布广,为了提高系统的可靠性和灵活性,需在前期充分考虑、仔细计算、留有适当余量;随着工程实施中各方案的变更而适时调整设计,并做好后续设备选型、采购、安装、实验等相关工作,以确保厂用电系统的稳定运行。

As a large-scale hydropower station with the installed capacity of 10 200 MW, Wudongde Hydropower Station is one of the key power sources in the “West-East Electricity Transmission Project”, which is thus of a very important role in the power system and also raises high requirements for the design of the auxiliary power system. The design of the auxiliary power system in Wudongde Hydropower Station is introduced, including the power source selection, power supply voltage grade and the auxiliary power wiring. Considering the large unit capacity and the widely distributed equipment of the station, proper allowance should be provided in the design of the auxiliary power system to improve its reliability and flexibility. With the progress of the construction, proper adjustment should be carried out timely. Also, the following work such as the equipment selection, purchase, installation and testing should be emphasized to ensure the stable operation of the auxiliary power system.
