摘　　要：随着新能源的不断发展,新能源电站无线网络安全威胁的防御问题日渐突出,为电网的安全稳定运行带来了挑战。从现有安全风险评估方法出发,从模糊分析理论入手,提出了一套电力监控系统无线接入安全评估方法;建立了一种针对电力监控系统无线接入风险的、由多层评估指标体系构成的安全评估模型,该安全评估方法根据实际运行中的各种工况,建立二级、一级评估指标,实现了安全风险的分层评估。结合具体实例对所得数据进行分析,结果表明本文提出的方法能够有效实现无线网络接入的安全评估。With the continuous development of new energy,the defense problem of wireless network security threats of new energy power stations has become increasingly prominent,which has brought challenges to the safe and stable operation of the power grid.It was started from the existing security risk assessment methods and starting from the fuzzy analysis theory,a set of wireless access security assessment methods for power monitoring systems was proposed;a multi-layer assessment index system was established for the wireless access risks of power monitoring systems according to various working conditions in actual operation,the safety evaluation method establishes two-level and first-level evaluation indicators,which realized the hierarchical evaluation of safety risks.Analyzing the obtained data with specific examples,the results showed that the method proposed in this paper could effectively realized the security assessment of wireless network access.
