摘要/Abstract

摘要： 大规模风电集中并网已经成为中国风电送出的主要模式,但由于电网的薄弱和无功补偿配合的不足,电网的损耗问题较为突出。针对电压降低和无功流动对损耗的附加作用,依据多无功补偿的调节特性,提出一种两阶段协调控制方法,将缓慢离散的电容器、电抗器在长时间尺度安排,将快速连续的静止无功补偿器(Static Var Compensator,SVC)、静止无功发生器(Static Var Generator,SVG)在短时间尺度安排,通过多无功补偿的分解协调,逐步实现降损的控制目标。以我国某大规模风电集中接入电网进行仿真计算,所提控制策略能够取得一定的降损效果。

关键词: 无功电压, 无功补偿, 降损, 协调控制

Abstract: It has been main mode in China that large-scale wind power has centralized into grid, but as the weakness of the grid and a lack of coordination among reactive power compensation devices, the grid loss problem outstands. Regarding to the effect of voltage reduction and reactive power flow on loss, based on characteristics of different reactive power compensation devices, a two-stage coordinated control method was proposed. The method arranged slow discrete capacitors and reactors at long time scale whereas rapid successive static Var compensator(SVC) and static Var generator(SVG) at short time scale. By decomposition and coordination of reactive power compensation devices, it gradually has reached the target of loss reduction. Taking a grid with large-scale wind power integration as the case, the proposed control strategy can achieve a considerable loss reduction result.

Key words: reactive power/voltage, reactive power compensation, loss reduction, coordinated control
