分岔发生在电力系统模型表现出电压崩溃一直是最近的几项研究的主题。虽然这样的模型已被证明承认各种分岔现象，电压崩溃可能是由最简单的这些，即由（静态）鞍节点分岔的名义平衡，一直占主导地位的观点。作者最近表明，电压崩溃可以发生“之前”的鞍结分岔。本文提出了电压崩溃的一种新的动力学机制：奇异吸引子的边界危机或混沌蓝天分岔。这一决定是达到一个例子电力系统模型类似于一个研究在最近的几篇论文。更一般地说，蓝天分叉（不一定是混沌的）被确定为重要的机制，值得进一步考虑在电压崩溃的研究。>
Bifurcations occurring in power system models exhibiting voltage collapse have been the subject of several recent studies. Although such models have been shown to admit a variety of bifurcation phenomena, the view that voltage collapse is triggered by possibly the simplest of these, namely by the (static) saddle node bifurcation of the nominal equilibrium, has been the dominant one. The authors have recently shown that voltage collapse can occur "prior" to the saddle node bifurcation. In the present paper, a new dynamical mechanism for voltage collapse is determined: the boundary crisis of a strange attractor or synonymously a chaotic blue sky bifurcation. This determination is reached for an example power system model akin to one studied in several recent papers. More generally, blue sky bifurcations (not necessarily chaotic) are identified as important mechanisms deserving further consideration in the study of voltage collapse. >
