【Abstract】 The voltage stability study platform for large receiving-end grids was established,and the new method combining "static analysis" and "long and medium-term time domain simulation" for analyzing dynamic voltage stability was proposed.Based on that,the voltage stability of East China large receiving-end grid was analyzed,and the features and mechanism of voltage collapse of large receiving-end grids were revealed.It was proposed that dynamic voltage instability is the key related factor challenging secure and stable operation of the receiving-end grid,and causes of dynamic voltage instability were also given.更多还原
