结合福建省仙游抽水蓄能电站的特点 ,对抽水蓄能电站的接入系统 ,电气的接线形式 ,主变容量的选择 ,电动发电机组起动方式的选用 ,换相开关的设置以及二次接线等作进一步的探讨。由于抽水蓄能电站担任调峰、填谷和事故备用 ,有其运行的特殊性 ,设计中应充分考虑电气主接线的可靠性、安全性。在二次设计中应考虑机组起动过程对保护的影响 ,以及发电、抽水时换相所引起二次接线的变化
According to the characteristics of Xianyou Pumped Storage Power Station in Fujian Province, this paper analyzes the characteristics of Panyu Pumped Storage Power Station, such as the access system of Pumped Storage Power Station, the wiring form of electrical, the choice of main transformer capacity, the selection of starting mode of alternator, For further discussion. As the pumped storage power station served as peak shaving, filling and accident backup, has its particularity of operation, the design should give full consideration to the reliability of electrical wiring, safety. In the secondary design should consider the unit start-up process on the protection of the impact, as well as power generation, pumping, commutation caused by changes in secondary wiring
