Safety Stability Research In Regional Power System

With the increasing of the load, regional power grid gets more and morecomplex. So it's meaningful to calculate and analyze grid's safety and stability inthe new power grid.The paper analyzes and concludes methods of safety stability calculationanalysis in regional power system. Introduced analysis steps and brought up staticstate stability and temporary state stability main points, mathematic model. Thereare some problems in regional power system, such as reactive power un-balancedvoltage beyond limits. The paper brings up correction theory based substation andsensitivity analysis. Applying two methods into practical electrical networkcalculation in order to solve voltage and reactive power un-balanced problem. Itputs forward some measures to solve and enhance stability level of electricalpower network.
