    摘要:

    结合中国电网交直流混联、电力电子化、清洁能源接入等发展态势,分析了现代复杂电网故障特性发生的改变,提出了当前继电保护技术面临的形势与挑战,总结了继电保护技术发展需要坚持的原则,探讨了“即插即用的就地化保护”、“优化配置的后备保护”、“智能化运维体系”、“三大继电保护技术支撑平台”、“直流控制保护”、“继电保护前瞻性技术”等重点发展方向。

    Abstract:

    Considering the new developmental tendency of the state grid including hybrid AC/DC power grids, the access of clean energy, and the power electronics dominated power systems, the changed fault characteristics of modern power systems are analyzed, meanwhile, the challenges and development situation faced by relay protection technology are proposed. Based on this, the principles to be persevered for relay protection technology development are summarized. The emphatic development directions are discussed in detail, namely, the plug-and-play outdoor installation protection, the optimally configured back-up protection, the intelligent operation and maintenance system, three technical supporting platforms of relay protection; the control and protection of high voltage direct current(HVDC)transmission; the forward technologies of relay protection.
