摘要
Abstract
In order to study the influence of Ningdong DC bipolar fault on the synchronized security and stability of North-Central China power grid, the coupling between Ningdong ±660 kV DC project and UHV tie-line transmission power was analyzed based on the theoretical analysis of UHV AC pilot project steady stability limit. The influence of DC bipolar locking on the peak flow of UHV tie-line was investigated. According to the practical case study, load model of Shandong Grid was identified as an important factor in computation. The stability control measures and deployment scheme for Shandong grid after the operation of Ningdong DC project were proposed and tested by simulation. HVDC modulation is selected as the method to enhance stability in North-East Grid. The research result can be used as reference for future implementation of stability control system for interregional interconnection power system.关键词
