《农田水利与小水电》1987年第3期所刊钟恒波同志《小水电低压机组的接线方式》一文,总结分析了我国小水电站,低压发电机组的中性线与主变中性点连接后接地(附图 a)的危害,提出发电机中性点绝缘(附图 b)的接线方式。并提出在并网时若出现零点电压飘移,发电机无法与电网同步时,应切除一切照明便可同期并网的操作方法。 “Farmland Water Conservancy and Small Hydropower” No. 3, 1987 Issue Comrade Zhong Hengbo “small hydropower unit wiring” a summary of China’s small hydropower stations, low-voltage generator neutral line and the main transformer connected to the neutral point (Figure a), put forward the generator neutral point insulation (Figure b) wiring. It is suggested that if zero voltage drift occurs during the grid connection and the generator can not synchronize with the grid, all the lighting should be cut off to operate in the same grid.
