摘　　要：针对当前风电场AVC系统无功出力分配算法功能单一,无法实现风电场电压调节成本最低这一问题,提出了风电场AVC系统协调优化控制策略。该策略通过二阶震荡粒子群法对带有罚函数的风电场无功优化模型进行求解以降低风电场有功损耗,并通过调整无功源的工作方式实现电网电压的稳定。以辽宁地区某风电场为例,建立了该风电场的优化计算模型和包含所提控制策略的仿真模型。仿真结果表明,该策略可在保证风电场并网点电压稳定的同时,有效减小风电场稳态运行过程中的有功损耗,并在电网发生故障时为电网提供一定的无功支撑。The function of distributing reactive power algorithm is single. The AVC system of wind farm can’ t reduce the cost of regulating voltage. To rich arithmetic functions,this paper presents a coordinating control strategy. This strategy uses the second-order oscillation particle swarm optimization to solve theoptimization model with penalty function which can reduce the loss of wind farm.Steady voltage is realized by adjusting the work methods of reactive power sources. Given wind farm in Liaoning is taken as the research object in this study,optimization and simulation model with the strategy is established. The simulation results show that this streategy can reduce the active loss and decrease the damage to the power grid.
