摘要:

针对风电场的无功电压问题,构建了风电场模型,提出了一种综合考虑双馈风电机组(doubly-fed induction generator,DFIG)和静止无功补偿器(static var compensator,SVC)的无功电压协调控制策略。建立了综合考虑风电场公共接入点(point of common coupling,PCC)的电压偏移量和无功源的无功裕度的目标函数。基于混沌量子粒子群算法对风电场进行无功电压控制,通过协调DFIG和SVC的无功出力,使得风电场PCC的电压满足要求,同时提高其无功源的无功裕度。最后,以华北某风电场为例进行算例分析,验证了所提无功电压协调控制策略的可行性及有效性。

Abstract:

A wind farm mode was established aiming at resolving the problem of the reactive voltage. And reactive voltage coordinated control strategy was proposed with comprehensively considering both doubly-fed induction generator (DFIG) and static var compensator (SVC). With considering the voltage deviation of the point of common coupling (PCC) and the reactive power margin of the reactive power source for wind farm, an objective function was established. Chaotic quantum-behaved particle swarm optimization (CQPSO) was used for the reactive voltage control of wind farm; by coordinating the reactive power output of DFIG and SVC, the voltage of PCC connected with power system was enabled to meet the requirement, and the reactive power margin of reactive power source was improved at the same time. Finally, a wind farm in North China was taken as an example for analysis, and the simulation results verified the feasibility and effectiveness of the proposed reactive voltage coordinated control strategy.
