If you lose power system stability, so it is impossible to use the loss figures to be calculated. Power system is stable or not will seriously affect the social and economic fields. In order to protect the interests of maximizing improve power system stability has become a world power construction on the main issues and explore orientation. The stability of the power system, including power system angle stability. Therefore, analysis of power system angle stability analysis of power system stability which is an integral part. Maintain the entire power system angle stability for systems bring the following benefits: on the one hand a stable system can bring a stable voltage, and improve power quality at the same time, but also to avoid causing a short circuit caused by high current and low voltage conditions, thereby reducing the risk of the power supply system; analysis from another aspect, if the power angle power system instability may occur some failure or malfunction of electrical protection, and ultimately lead to significa
