摘　　要：湘西地区是湖南省的主要电源所在地,其区域电网的稳定性受水力发电季节性特征和风力发电逐步上网的影响.为了提高送端区域电网稳定性,将超导磁储能系统接入湘西地区电网,利用其特性对电网进行实时快速的功率支撑,从而解决因系统故障或新能源接入造成的失稳问题.在电力系统综合分析程序中搭建等效简化模型并模拟电网扰动,接入超导磁储能系统,通过系统功角和电压的变化分析其对系统稳定性产生的积极影响.Xiangxi is the main power source of Hunan Province.The stability of Xiangxi regional power grid is affected by the seasonal hydroelectric power generation and the wind power generation.In order to improve the stability of Xiangxi regional power grid,the superconducting magnetic energy storage(SMES)system is connected to provide real-time and rapid power support to the power grid,so as to solve the instability problem caused by system failure or new energy access.We build an equivalent simplified model in power system analysis software package and simulate the disturbance of the power grid.Then we connect the superconducting magnetic energy storage system in above model,and analyze its positive impact on the stability of the system through the changes of the power angle and voltage of the system.
