风电场多支路并列运行SVC的无功潮流优化与控制策略研究

Research on ORPF & Control Strategy of Wind Field Multi-drop Parallel Operation SVC

针对风电场多支路独立并列运行时存在无功振荡的问题,结合风电机组模型,提出并列支路的闭环调节共用同一PID模块,整个无功潮流优化与控制系统由1台无功潮流优化控制单元进行集中控制的策略,从SVC的工作原理、控制策略和多支路并列运行时的潮流优化等方面进行分析,认为该策略满足了电力系统接入条件,使风电场的损耗明显降低。

Aiming at the multi-drop independent parallel runtime of the reactive power oscillation problems,combined with the wind turbine model,this paper puts forward a parallel branch closed-loop regulating shared one PID module,the tide of reactive optimization and control system by 1 reactive current optimization control unit for centralized control strategy,analyzes from the working principle of SVC,control strategy and multidrop tied for the runtime optimization,etc,and ecreases obviously the trend of thought that strategy to meet the power system access conditions,to make the wind loss.
