Development of SSO/SSR Small Signal Analysis Software Based on Objected-Oriented Technology and Modularization
Small signal analysis method is one of the most important methods in power system stability analysis.It is necessary to develop a visualized SSO/SSR small signal analysis program which can analyze subsynchronous oscillation(SSO) and subsynchronous resonance(SSR) phenomenon in power system.In the process of software development,small signal modeling is the most important task.In this paper,object-oriented technology and modularization are used in small signal modeling which can analyze SSO/SSR in power system.A general method for electric network modeling based on electromagnetic transient model is also put forward,which makes it realizable to develop general and visualized SSO/SSR small signal analysis software.
