| 摘 要： | 电网的安全稳定运行对国家的发展与人民的安稳有着至关重要的作用，随着科学技术的不断发展，用电需求呈现高速的增长，电网故障的种类也愈加复杂。因此，电网的维护方式亟待更新发展。基于N-1事件，通过对事故后的潮流进行分析计算，提出了一种基于状态叠加算法的输电断面稳态安全域计算数学模型。并以湖北电网为例，验证了上述方法的可行性与有效性。

| Abstract: | The safe and stable operation of the power grid plays a vital role in the development of the country and the stability of the people.With the continuous development of science and technology，the demand for electricity is increasing rapidly，and the types of grid faults are becoming more and more complicated.Therefore，the maintenance method of the power grid urgently needs to be updated and developed.Based on the N-1 event and analyzing and calculating the power flow after the accident，a mathematical model for the calculation of the steady-state safety zone of the transmission section based on the state superposition algorithm was proposed.Taking Hubei Power Grid as an example the feasibility and effectiveness of the above method were verified. |
