This paper presents the stability limits prediction by sensitivity based BCU method using network structure preserving model. The main feature is that it does not rely on the assumption that the controlling unstable equilibrium point does not change when the operation parameter changes.

阐述了电力系统结构保持模型下基于灵敏度的BCU方法，其显著特征是当运行参量变化时不依赖于主导不稳定平衡点不变的假设。
