智能电网综合动态等值技术在电力系统中的应用

Application of Smart Grid Integrated Dynamic Equivalence Technology in Power Systems

本文将相似理论应用于动态等值技术中,并以同调等值法为例研究了智能电网综合动态等值技术在电力系统中的应用。从实例仿真效果来看,采用相似理论处理的动态等值技术,等值前后电力系统变化显著,尤其是等值优化后电力系统与原系统曲线基本保持一致。因此,通过相似理论量化处理等值前后系统故障响应特征信息,可以优化改进动态等值中的各参数,实用效果较好。

This paper applies similarity theory to dynamic equivalence technology,and takes the homology equivalence method as an example to study the application of intelligent grid comprehensive dynamic equivalence technology in the power system.From the simulation results of the example,it can be seen that the dynamic equivalence technique processed by similarity theory has significant changes in the power system before and after equivalence,especially after equivalence optimization,the power system curve remains basically consistent with the original system curve.Therefore,quantifying the fault response feature information of the system before and after equivalence through similarity theory can optimize and improve various parameters in dynamic equivalence,and the practical effect is good.
