基于燕尾突变流形的电压稳定性判断方法研究

摘要

电压不稳定甚至崩溃是造成电力系统灾难性事故的主要原因之一，为了能够给调度人员争取控制时间，在线判断电力系统的稳定性和稳定裕度十分必要。将突变理论应用于系统电压的稳定性判断，并提出了基于燕尾突变流形的节点电压稳定性判断方法和指标，算例结果表明了该方法的有效性。%Power system voltage stability was one of the main reasons that cause the system to catastrophic accidents, and it was necessary to determine the stability of the power system and its margin online. It was the first attempt to apply catastrophe theory to judge voltage stability of the system and node, and voltage index indicating margin of voltage stability based on swal owtail manifold was proposed. The effectiveness of the proposed method was validated by the numerical result.
