一种小水电集中区域的电压无功控制系统
摘要：
本发明公开一种小水电集中区域的电压无功控制系统，包括：分别设置在各个小型水电站中，对所述小型水电站的上网电压进行调节的有载调压变压器；设置在各个小型水电站相互连接的配电线路上的串联调压器；分别与所述多个有载调压变压器及所述串联调压器相连接，依据所述各个小型水电站的上网电压的浮动信息对所述多个有载调压变压器及所述串联调压器进行控制的控制器。本发明中通过在各个小型水电站中设置有载调压变压器及在各个小型水电站相互连接的配电线路上设置串联调压器，可以对各个小型水电站的上网电压进行调节，避免某个小型水电站的上网电压过高，导致其它小型水电站无法正常发电的状况发生。
摘要（英）：

The invention discloses a voltage reactive power control system of a small hydropower concentration area. The system comprises on-load voltage regulation transformers, series voltage regulators and controllers, wherein the on-load voltage regulation transformers are arranged in small hydropower stations respectively and regulate grid connection voltage of the small hydropower stations, the series voltage regulators are arranged on mutually-connected distributing lines of the small hydropower stations, and the controllers are respectively connected with the on-load voltage regulation transformers and the series voltage regulators and control the on-load voltage regulation transformers and the series voltage regulators according to floating information of the grid connection voltage of the small hydropower stations. Due to the facts that the on-load voltage regulation transformers are arranged in the small hydropower stations and the series voltage regulators are arranged on the mutually-connected distributing lines of the small hydropower stations, the grid connection voltage of the small hydropower stations can be regulated, and the situation that the grid connection voltage of one certain small hydropower station is too high, and accordingly other small hydropower stations can not generate electricity normally is avoided.
