| Power system voltage stability is one hotspot of power system research.In recent years, with the evolution of load characteristics people imminently want to establish the dynamic models of power system to study its behavior characteristics.In this paper,the emphasis is the research on the influence of air-conditioning characteristic on dynamic voltage stability.Firstly,enumerating dynamical analysis arts of voltage stability,air-conditioning model,and emulator programs,this paper is choosing befitting analysis art,models and software;this paper calculates the percent of air-conditioning based on a great deal load information and temperature data;this paper is using FORTRAN and PSS/E to construct air-conditioning model and join in the feebleness BUS of system which is gained from using eigenvalue method,and simulates the influence of air-conditioning characteristic on dynamic voltage stability.Meantime it obtains that the startup of air-conditioning group in3-5s differs,the influence on dynamic voltage stability differs. |
