Abstract

The distance of electricity transmission gets longer and longer, and capacity is also increasing, the voltage level by transport is becoming more and more high, while the stability problem of power system is more and more prominent. If the power system's stability is destroyed, that can cause blackouts, and it will form a very serious accident. This paper uses a single and infinite system as the object, which is modeling. Simulation experiment, analysis for the stability of transient. In addition, the limit removal time under different fault types, the influence of electric parameters which changes on transient stability is studied. Through the research, we gets a meaningful conclusion, that can help study further measures for improving the transient stability of power system.
