改善电网电压延迟恢复的动态电压/无功灵敏度方法
Dynamic Voltage/Reactive Power Sensitivity Method for Improving Fault-induced Delayed Voltage Recovery of Power Grid
摘要
Abstract
In order to improve the recovery of power grid voltage after fault,this paper studies the effect of reactive pow⁃er output on the recovery of critical bus voltage. First,this paper analyzes the reason of delayed voltage recovery after the fault,and the effects of a generator on the voltage recovery process. Then,based on the construction of a dynamic voltage reactive power sensitivity model,a method for evaluating the contribution of excitation generator to the critical bus voltage is proposed. Finally,the delayed voltage recovery of Guangdong power grid in 2013 under the ultimate con⁃dition is simulated. The results show that the method proposed in this paper can provide reference for reducing the recov⁃ery time of critical bus voltage.关键词
