摘要
Abstract
Loss of voltage stability will result in power system voltage collapse, so it is an important task to identify the bus close to voltage stability limit and through the adoption of control measures to prevent the voltage collapse as far as possible in power system stability analysis. On the premise of voltage stability the equivalent analysis of radial distribution network is conducted, and the linear load index of the voltage stability (VSL) for radia systems based on different load models is presented. On the basis of VSL, the system weakest feeder and the voltage collapse point can be correctly determined by heuristic choice. When the lowest bus voltage drops by 10% rated voltage, its load increase is taken as load margin, and critical load of radial distribution system is obtained. The proposed VSL is tested on radial distribution system consisting of 69 buses, the results show that the VSL is effective and valid.关键词
