Optimization of 400V Auxiliary Power Supply System for Pingban Hydropower Station

发电厂厂用电应保证对厂用负荷可靠和连续供电,使发电厂主辅设备安全运转,接线应能灵活地适应正常、事故、检修等各种运行方式要求。文章介绍平班水电厂厂用电的布置方式及设计中存在的薄弱环节,提出了不同的优化配置方案,通过对方案进行技术经济比较,最终使用了合理可行的方案进行优化配置,经运行观察达到了预期的效果。

The auxiliary power supply shall guarantee the reliable and continuous supply for all auxiliary loads so as to make all equipments run safely. Its wiring shall be fit to all kinds of operating requirements such as normal running, emergency and maintenance. This paper makes sign of auxiliary power supply, and proposes different comparisons, the most reasonable and feasible scheme practical running. an introduction to the layout and bottlenecks in the de- optimization schemes. Through technical and economic is chosen and the desired results are obtained through
