摘要
结合江苏近阶段开发建设的海上风电场项目,介绍了海上风电接入系统并网的电压等级、并网回路数的选择原则,讨论了长距离海缆并网的大型海上风电场输电系统的无功平衡、内部过电压限制措施,并通过工程实例,探讨了一种解决大型海上风电场接入系统后引起电网电压波动的无功补偿配置容量计算原则及方法。
Combining with the last constructed offshore wind power farm in Jiangsu Province, the selecting principles of integrating voltage level and number of connecting circuits are introduced. The reactive power balance and the court-measures for inner over-voltage of large-scale wind farm connected to the power grid through a long distance transmission line are discussed. Based on an engineering project, a method for reactive compensation capacity calculation for large-scale offshore wind farm is proposed.
