| 摘 要： | 负荷模型研究的主要目的是为电力系统稳定计算提供精确的负荷模型。采用乐观或保守的负荷模型将会对电网安全或经济运行造成不利影响。随着系统规模的不断扩大和新型用电设备不断出现,负荷的动态特性也变得越来越复杂。早期的简单负荷模型已经不能满足当前互联电网稳定计算的需要。综述了负荷模型的发展历史、负荷建模的常用方法、常用负荷模型及对系统稳定的影响,结合最新研究进展,提出了应该建立区域电网负荷模型动态数据库,并指出了下一步需要研究解决的问题。

| Abstract: | The aim of load model research is to provide precise load model for power system stability computation.Optimistic load models will endanger the safe operation of power system and pessimistic ones will degrade its economy.As continue extending of power grids and emerging of new-style facilities,the dynamic characteristics of loads become more and more complicated.The early simple load model can not meet the need of stability computation of present interconnected network.In this paper,the development history of load model and the usual approaches in load modeling are summarized,as well as the influence of load model on the power system stability.Based on the latest research,this paper proposes that load model dynamic database in regional power grid should be established and presents some problems. |
