摘　　要：随着电网建设的不断完善,发输电新技术的不断涌现,对电力系统可靠性评估的准确性和全面性提出了新的要求。从发输电系统可靠性元件的建模入手,分析了发输电元件模型多态化、计及因素多样化的发展趋势;重点讨论了包括特高压直流输电、柔性直流输电、计及储能装置的风力发电等新型发输电设备,以及FACTS元件、电动汽车在内的元件概率可靠性模型的建立方法、对发输电系统可靠性的影响和存在的不足,最后论述了需要进一步深化研究的方向。With the dewdopment of power grid construction and the constantly emerging of new power generation and transmission techniques, the new requirements for power system reliability evaluation are put forward in the aspects of accuracy and comprehensiveness. Starting with the reliability modeling of generation and transmission components, the trends of muhi-state models with more consideration factors of the generation and transmission components were analyzed. The probabilistie reliability modeling methods for uhra HVDC transmission, VSC-HVDC, wind power plants with energy store devices. FACTS devices and eleclric vehicles were discussed, as well as their effects on generation and transmission system reliability and the existing shortcomings of the new devices. Finally, the problems to be further researched in future were proposed.
