| 摘 要： | 为了研究风电机组因电压异常导致的大规模脱网问题,通过对宁夏电网的电源分布和网架结构进行了计算建模,从风电场配置动态无功补偿装置和改进风机耐高压定值两方面仿真分析了电压异常对风机脱网的影响。仿真结果表明,性能良好的动态无功补偿装置和较好的风机短时耐高压性能可降低风电机组因电网电压异常而脱网的风险。

| Abstract: | In order to solve the problem of the large- scale inaccessibility of wind power generatorsdue to voltage abnormality, by the calculation and modeling of the power distribution and gridstructure of Ningxia power grid, simulates and analyzes the influence of voltage abnormality on theinaccessibility of wind .power generators from the two aspects as the dynamic reactivepowercompensation devices and improving the withstand high voltage setting of the wind generators. Thesimulation results show that the fine performance of the dynamic reactive power compensation devicesand the better short time withstand high voltage performance of the fan can reduce the risk of the newenergy generators inaccessibility due to voltage abnormality. |
