摘要
Abstract
With the increasing diversity of distribution load and the large scale accessing of wind power, the problem of voltage stability in regional grid is gradually highlighted, traditional off-line analysis can not conduct a real-time tracking of the power system, and on-line analysis is applied only in province grid. Based on energy management system, on-line early warning system for voltage stability in regional power grid is designed and implemented by applying sensitivity analysis and method for continuation power flow. In this paper, the warning system is used to model the rive traction loads and two wind plants. Based on multiple data integration, the index of voltage stability and information of early warning are given on real time, the weak links are provided and reported automatically. The system was put into operation in Xinyang power system and recognized by dispatchers.关键词
