目前,小水电主要采用35千伏及35千伏以下的输电线路,并入35千伏电力系统运行。随着小水电的发展,将逐渐采用110千伏输电线路,直接并入110千伏电力系统运行。110千伏电力系统与35千伏电力系统相比,有着不同的特点。我们在进行水电厂同期系统设计时,必须注意这些特点,采取相应的措施。南河水电厂装机容量为20800千瓦,三台发电机接在6.3千伏母线上,经过一台25000千伏安的主变压器升压至110千伏后,并入赣
At present, small hydropower mainly uses transmission lines below 35 kV and 35 kV and is integrated into a 35 kV power system. With the development of small hydropower, 110 kV transmission lines will be gradually adopted and directly incorporated into the 110-kilovolt power system. The 110 kV power system has different characteristics compared to the 35 kV power system. When we carry out the same system design of hydropower plants, we must pay attention to these characteristics and take corresponding measures. Nanhe Hydropower Plant installed capacity of 20800 kilowatts, three generators connected to the 6.3 kV bus, after a 25000 KVA main transformer boost to 110 kV, after the merger Gan
