摘要
由于甘肃省特殊的地理条件,东西跨距长约2 000 km,受经济发展水平的制约,电网网架由弱到强逐步发展的特点非常明显,而且电网建设周期较长,终端变电站较多,再加上电源项目的建设具有不确定性,局域电网对动态无功补偿的需求也在发生变化,这些都为RSVC在甘肃电网的应用提供了较大的发展空间。系统介绍了甘肃电网无功管理存在的问题,探讨RSVC在甘肃电网应用的可能以及将会产生的效果。
From east to west, the span of Gansu province is about 2 000 kilometers. Because of this special geographical condition, the economic development is resisted in many areas of Gansu province and it is obvious that the electrical framework is from weak to strong. Construction cycle of the electrical network is long and there are many terminal transformer substations, moreover, there is uncertainty in electric power source construction and the demand of dynamic reactive power compensation in supercentral electric network is changing. All of these have provided a large development space for the application of RSVC in Gansu electric grid. This paper introduces the problems existing in the reactive power management of Gansu electric grid and investigates the possibility of the application of RSVC in Gansu electric grid and its impact in a comprehensive way.
