大量风电接入对地区电网电压的影响研究

摘要

The status of the large scale interconnected wind plants in Jilin power grid is proposed.The influence of system voltage about large scale interconnected wind plants active power in the power grid is analyzed.Based on the structure of Jilin power grid in 2010,the influence of the system voltage about the active power of the wind plants is simulated.Lastly ,the effect of the bus voltage of the substations about the response speed of the reactive power com pensation equipments is studied.The analysis and the simulation results are verified by the operation datas.%首先介绍了吉林电网风电接入情况,从理论上分析了风场有功出力对系统电压的影响,并在2010年底网架结构的基础上,利用仿真软件计算出风电有功出力对地区电网电压的影响,最后考察了有功出力快速变化时无功补偿装置响应速度低对相关厂站母线电压的影响.理论分析和仿真数据得到了实际运行数据的验证.
