摘要
宝泉抽水蓄能电站为适应机组在发电和抽水工况的不同磁场旋转方向,设置了换相闸刀、被拖动闸刀、拖动闸刀、起动母线及特殊设备,并针对各种特殊工况下的非常运行方式,设置了电压相序监视保护、低频保护、低功率保护、逆功率保护、低频过流保护及定子保护。从而实现其调峰填谷、调节电压频率及事故备用等功能。
In order to be suitable to different rotation directions of magnetic field under the conditions of power generation and water pumping of units, the Baoquan Pumped Storage Power Station installs the phase change knife switch, the driven knife switch, the driving knife switch, the starting-up busbar and specific equipment. Meanwhile in accordance with the emergency operation modes under various particular working conditions, it also sets up the voltage phase order surveillance protection, the low frequency protection, the low power protection, the reverse power protection, low frequency over-current protection and the stator protection. Thus the Station realizes its functions of peaking and valley-filling, voltage and frequency modulation and emergency reserve.
