摘　　要：随着时代的不断发展和人们生活水平的不断提高,电力系统也在与时俱进。输电电网的扰动也越来越明显,在电网输电过程中,如果不能对电网扰动进行分析,就会导致电网连锁事故或电网大规模停电。主要研究电网扰动的传播特性,引用了生物学领域中成熟的SIS模型,将其与电网的扰动传播相结合,通过对电网扰动传播的模型和类比分析,分析了电网扰动传播对电力系统稳定性的影响,更容易进一步跟踪和定位干扰来源。该模型仿真表明,此方案可以有效地处理扰动传播的影响,使电力系统更加安全、稳定的运行。With the continuous development of The Times and the continuous improvement of people's living standards,the power system is advancing with The Times.The disturbance of the transmission network is becoming more and more obvious.In the process of power transmission,if the disturbance of power network cannot be analyzed,it will lead to chain accidents or large-scale power outage.This paper mainly studies the propagation characteristics of power grid disturbance,the mature Susceptible Infected Susceptible(SIS)model in biology is introduced and combined with disturbance propagation in power grid.The influence of grid disturbance propagation on power system stability is analyzed by model and analogy analysis,which makes it easier to further track and locate the source of disturbance.The simulation results show that the proposed scheme can effectively deal with the influence of disturbance propagation and make the power system run more safely and stably.
