由长办施总可控硅整流设备厂研制的KGL—XJ系弱可控硅励磁装置,主要是解决农村小水电并网、无功调节等问题,可与500午瓦以下发电机组配套。自1981年投产以来,已先后在国内30多个小水电站40多台机组上运行使用,效果显著。这些电站用该装置取代原有的电抗分流、三次谐波等老式励磁方式后;立即改变了经济亏损的被动局面,有的电站收入当年就翻了一番。因此,该装置深受用户的好评。
The KGL-XJ weak thyristor excitation device developed by the chief executive of the SCR rectifier plant mainly solves the problems of rural small hydropower grid connection and reactive power adjustment, and can be used with 500-watt or less generator sets. Since it was put into operation in 1981, it has been used in more than 40 units in more than 30 small hydropower stations in China, which has achieved remarkable results. These plants replaced the original reactance shunt, the third harmonic and other old excitation methods; immediately changed the economic loss of the passive situation, and some power station revenues doubled that year. Therefore, the device is well received by users.
