摘要
Abstract
Load is an important part of the power system,a rational model of load is of significance to security and stability analysis of power systems.Currently,the most widely used is the model for composite load.However,more than 10 dynamic parameters of a composite load model are needed for its complete description,which makes it difficult to identify all of them for online analysis and use.By proceeding from the state equation of the composite load model while ensuring the criterion for transient responses to be approximately equal,a method for composite load model simplification is proposed.On this basis,an analysis is made on the influences of different parameters on the load dynamic characteristics as well as the correlation between parameters.Finally selecting the percentage of motor load,the transient reactance of motor,the initial slip of motor and the rotor inertia constant of motor as the parameter set to be identified with the conclusions proved by simulation results.关键词
