Low Frequency Oscillation and Vulnerability Analysis of Power Grid Based on the Fault Chains
摘要
Abstract
Vulnerability analysis of power grid is the important basis for low frequency oscillation monitoring, control and prevention. Using the fault chains principle, reasonable multi-disturbances were established based on the typical fault mode of flow transferring and overload of transmission lines caused by line faults. Power oscillation caused by multi-disturbances was researched and the influence of operation modes to the occurrence of low frequency oscillation of equal or increasing amplitude was studied. According to the fault chains set and structural importance index, power grid vulnerability was analyzed. The results show that the heavy duty lines and the lines that are easy to be influenced are the key parts of power grid vulnerability and the increase of power exchange capacity isthe important factor to the occurrence of low frequency oscillation of equal or increasing amplitude.关键词
