Through the characteristic analysis of reactive power compensation installation and assemble type capacitor in China, this paper describes the necessity and advantages of using assemble type capacitor combined with the application example of assemble type capacitor in central hub substation in China.

Optimization Design of Main Turbine Parameters of Dadingzishan Navigation-Power Junction;

In general layout design of Dadingzishan navigation-power junction on the Songhuajiang River,a comparison .

Based on the results of experimental study on navigation technique of Xiangjiang River Zhuzhou Navigation-Power Junction, this paper deals with the general layout principle of navigation-power junction at slightly curved braided reach, and presents analysis and comparison between the three schemes for plan layout.

Channel regulation affected by unsteady flow released from hydraulic power stations;

The unsteady flow released from hydraulic power stations is characteristic of the great changes of water level and runoff during a day,which brings great effects on riverbed process and navigation conditions of the downstream reach.
