摘要: 大型海上风电场并网对电力系统电压偏差、电压波动、闪变及谐波等带来较大冲击。以海南D海上风电场为研究对象,分析D海上风电场的动态无功补偿装置SVG容量,以及220 kV公共连接点电压偏差、电压波动与闪变及谐波的限制值。分析风电场在4种典型运行工况下,0%~100%出力区间电压偏差及切换操作引发的波动闪变值。仿真分析2~25次谐波电流及电压畸变率对系统的影响,结果表明,D海上风电场各项指标全部符合国家标准限值要求,并网方案具有技术可行性,为同类大规模海上风电接入电网评估提供了工程参考。

Abstract: The grid integration of large-scale offshore wind farms exerts significant adverse impacts on power systems in terms of voltage deviation, voltage fluctuation, flicker, and harmonics. Taking Hainan D Offshore Wind Farm as the research object, this paper analyzes the power compensation capacity of static var generator (SVG), as well as the corresponding limit values of relevant power quality indicators at the 220 kV point of common coupling. It also examines the voltage deviation and fluctuation and flicker values caused by switching operations in the 0% to 100% output range under four typical operating conditions of the wind farm. The impact of 2nd to 25th harmonic current and voltage distortion rates on the system is simulated and analyzed. The results indicate that all indicators of D Offshore Wind Farm comply with national standard limits, and the grid connection scheme is technically feasible, and the obtained results can provide reliable engineering references for the power quality assessment of similar large-scale offshore wind power grid integration projects.
