【摘要】：围绕近海风电场群接入电网的规划原则开展研究。系统总结了近海风电场接入电网的输电模式、并网电压等级、升压站无功补偿配置等规划方案选择问题。重点针对多个海上风电场接入同一区域电网时公共连接点(point of common coupling,PCC)点的选择问题进行了研究,通过理论模型分析了影响多个风电场接入后系统电压波动幅度的关键因素和电压波动的计算方法,并提出了PCC点选择的基本原则。通过珠海近海风电场群接入方案规划为实例,对比理论计算和数值仿真分析的结果,验证了所提测算方法的正确性。
[Abstract]:Research on the planning principle of access to the grid by the near sea wind farm group. This paper systematically summarizes the selection of the planning schemes, such as the transmission mode, the grid voltage level, the reactive power compensation configuration of the boost station, and so on. The key for a number of offshore wind farms into the same area when the public grid connection point (point of common coupling, PCC) selection problem is studied, the impact of a number of wind farms after the key factors of system voltage fluctuation amplitude and voltage wave calculation method was analyzed based on the theoretical model, and puts forward the basic principles PCC point selection. The correctness of the proposed method is verified by comparing the results of the theoretical calculation and numerical simulation analysis through the example of the Zhuhai offshore wind farm group access plan.
