摘　　要：地区电网作为电力用户供电的核心,其承担着尽可能多的吸纳新能源、给用户提供可靠经济电能的责任,是现代智能电网重点发展的环节。针对地区级电网的实际情况,重点研究继电保护在线整定计算以及继电保护在线评估与预警,解决地区电网中继电保护定值与电网的适应性问题,同时,针对石家庄地区电网的实际情况研究实现地县继电保护整定计算与定值管理一体化系统,对提升继电保护的性能具有重要的理论意义及实用价值。As the core of power supplier, regional power grid takes responsibility for absorbing energy as much as possible and providing consumers with reliable economical electric energy. It is the key link in the development of modem smart grids. For the current situation of regional grid, this paper focuses on the online setting calculation, evaluation and forewarning of reply protection. It solves the contradiction between set value of reply protection and grid＇s adaptability in the regional grid. At the same time, it also researches and realizes the integration between setting calculation and management of the prefectural and county reply protection for the realities of regional grid at Shijiazhuang. It has important theoretical significance and practical value for the improvement of reply protection.
