摘要(Abstract):
通过对风电机组并网系统进行建模,从保护安全、电能质量、线损等方面分析了分布式电源接入后对电网的影响,结合岱山美达一期风电场实测数据和网架结构,从有功频率控制、无功功率控制、低电压穿越和五端柔性直流输电接入4个方面分析其运行特性,从而论证风电机组运行特性对电网的适应性。
By modeling the integration system of wind power generating sets, the paper analyzes the impact of DG integration on the power grid in terms of protection safety, power quality and line loss. In accordance with the measured data and grid structure of Daishan Meida phase-I wind farm, the paper analyzes the operation characteristics active frequency control, reactive power control and LVRT and the five-terminal VSC-HVDC integration to demonstrate the operation characteristic adaptability of wind turbines to power grid.
