Xinzhou Power System Status And Safety Stability Analysis

With the development of economy, the power system keep to the development of high voltage, long distance and lage capacity. At the request of improving economic benefits, the safety and power quality problems have becoming increasingly prominent. In recent years, large area and long time blackout accidents have happened at home and abroad,which not only cause huge economic losses, but also threaten social order. Therefore, evaluating quantitatively and maintaining power system safe and stable become necessary and urgent.Xinzhou power grid is an important channel in Shanxi province bridging north and south, irreplaceable to the development of Xinzhou, even Shanxi province. In order to ensure the security and stability, it is necessary to analyze the present situation of network system situation, find out the weak links existing in the network, and put forward the corresponding improvement measures and suggestions. This work can not only run and management guidance of Xinzhou power grid, but also improve the ability and lay a good foundation for the continuous and safe operation of power grid.In this paper, through investigating grid parameters, collecting the data and other information of Xinzhou power grid, the current status of the grid based on the analysis of power demand and supply capacity is mastered and power balance is calculated. Calculation and analysis to the various operating modes of power grid, about stability and short-circuit current is done. It is proposed study the rationality and safety stability of Xinzhou power grid for the network structure according to the results mentioned above.
