同步电动发电一体机负载突变时动态稳定性研究

Research on Dynamic Stability of Synchronous Electric Generation Motor under Sudden Load Change

结合11 MW供氧用同步电动发电一体机的实例,就机组中汽轮机故障停机快速切除后,电机由空载瞬间跳变为满载电动,或电机由满载发电跳变为满载电动工况下一体机动态稳定性展开分析、研究。

Based on an 11MW synchronous electric generation motor for oxygen supply,it analyzes the dynamic stability of the motor under the condition that the motor suddenly changes from no-load to full load,or changes from full load generator to full load motor,after the turbine fault is quickly cut off.
