摘　　要：针对现有方法平均电量输出时间较长,电子供应量不稳定,不能有效保障电网电压稳定的问题,提出基于空调群负荷大量接入条件的大区域电网电压稳定性研究方法。搭建大区域电网环境,参考电网组织的基本结构形式在电网环境中设置Simulink负荷模块与稳压滤波器。在环境支持下通过机组并网控制、电网潮流量计算、电压稳定裕度指标确定实现对大区域电网电压稳定性的研究。实验结果表明,所设计方法的平均电量输出时间较短,电子供应量变化趋势稳定,能够保障电网环境的稳定运行。Aiming at the problems of long average power output time and unstable electronic supply,the existing methods can not ef-fectively guarantee the voltage stability of power grid,so a research method of voltage stability of large regional power grid based on the condition of a large number of air conditioning group loads is proposed.To build a large regional power grid environment,reference to the basic structure of the grid organization,the Simulink load module and voltage regulator filter are set up in the power grid environment.Under the support of the environment,the research on the voltage stability of large area power grid is realized by grid connected control of units,calculation of power flow and determination of volt-age stability margin index.The experimental results show that the average power output time of the design method is short,the change trend of electronic supply is stable,and the stable operation of power grid environment can be guaranteed.
