摘　　要：针对海上风电集群的无功补偿配置问题,在充分考虑双馈式发电机(DFIG)的无功调节能力及机群拓扑结构对海上风电无功优化影响的基础上,计及高压海缆对地电容与匝间电容的影响,以降低海上风电集群有功功率损耗和使离散设备调节的成本支出最小为目标函数,将海上风电集群内各节点电压偏差作为罚函数,建立了适用于海上风电集群和高压海缆一体的无功优化模型,采用细胞膜优化算法分别计算DFIG额定功率和空载两种运行方式,得到无功补偿配置最优方案。算例分析表明,该算法有效可行。Aiming at the problem of reactive power compensation for offshore wind power clusters, a reactive power optimization model was presented, which takes account of the ground capacitance and intertern capacitance of high voltage cable based on full consideration of the impact of reactive power regulating capability of DFIG and topological structure of offshore wind power cluster. In the model, the objective function was taken as reducing the active power loss and minimizing the cost of discrete equipment regulation. At the same time, the voltage deviation of each node in the offshore wind power cluster was taken as the penalty function to guarantee the voltage stability. Cell membrane optimization algorithm was used to obtain the optimal scheme of reactive power compensation under the rated power operating mode and no load operating mode of DFIG. The feasibility of the algorithm was verified by the example.
