【摘要】 基于求解非线性优化问题的扩展Ｈｐｆｉｅｌｄ模型，分别计算出电力系统不同运行状态下的静态安全域，进而提出用一ＢＰ模型来映射这种关系。通过使用该ＢＰ模型的一种改进算法，可方便地计算出任意运行状态下的安全域，使其能够满足实时分析的要求。更多还原

【Abstract】 ased on the expanded hopfield model to solve nonlinear optimal problems,this paper proposes amethod tO calculate steady-state security region in varions operation states,and reflect this relation by aBP model.Through calculating the security region by the modified algorithm of BP model,real time analy-sis can be carried out. The results demonstrated the effectiveness of the method.更多还原
