为给特高压电网小干扰、暂态电压、功角等的稳定计算和分析奠定基础,在区域电网公司能量管理系统(energy management system,EMS)和广域测量系统(wide area measurement system,WAMS)记录的国内某两大区域电网间2008年底先后进行的500 kV联网、特高压联网试验两次试验基础上,通过校核网络结构、调整电网有功和电压、优化扰动模拟方案等一系列调试、分析方法,成功将潮流、暂态过程波形调整至与实测值相符,复现出了两次联网试验的暂态过程,从而校核了联网系统静态和动态仿真模型及参数的正确性,为后期进行暂态稳定仿真与分析、小干扰稳定计算分析奠定了基础.

Two regional power grids were interconnected successfully in the end of 2008 via 500 kV EHV system and 1000 kV UHV system individually.Based on the field data of the two interconnection tests,which were recorded by energy management system(EMS)and wide area measurement system(WAMS),power flow and transient procedure of the tests were well recurred by simulation through a series of adjustment and analysis,such as verifying network structure,adjusting active power and voltage,optimizing disturbance procedure.The results prove the effectiveness and accuracy of simulation model and parameters of the interconnected power grids.
