继电保护检验新技术探索

Exploration of New Technology for Relay Protection Testing

从保护不正确动作的路径因素模型出发,分析了现有继电保护检验手段存在的不足,提出高保真不停电检验新技术。研究了一种基于继电保护信息管理子站,利用保护实时运行信息实施远程监视和诊断的辅助平台,以及在不改变设备正常运行状态的条件下,开展保护及其跳合闸等回路检验检测的方法,并进一步阐述了不停电检验技术在消除检验死角、降低作业风险、提高检验效率以及不影响电网一次设备运行等方面的优势。最后,通过工程应用实例验证了高保真不停电检验技术的可行性与完备性。

From maloperation path factor model of protection,an analysis is made of the inadequacy of existing protection inspection technique,and a new inspection technique of high fidelity and power-on test is proposed.Research on a kind of remote monitoring and diagnosis auxiliary platform is going on based on the protection information management substation and protection real-time operation information.And protection device and tripping circuit inspection test without changing the equipment normal operation has been carried out,while the advantages of power-on technique are briefly treated,such as elimination of inspection blind angles,reducing operation risks,improving inspection efficiency without affecting power system primary equipments operation.Finally,the feasibility and completeness of the power inspection technique is verified by actual engineering application experiment.
