电网实时复杂的运行方式使得传统的定值校核方法存在某些特定情况下定值性能降低的情况；定值采用县调计算、地调复核的应用模式，地县间交界的定值性能需要有一定的手段进行评估。为了解决上述问题，研究了基于地县一体化继电保护定值在线校核系统实现方案。在介绍地县一体化继电保护定值在线校核系统功能体系和定值在线校核数据源获取的基础上，提出了地县一体化交界定值在线校核的策略，重点介绍了地县交界面的智能识别、校核原则设计以及校核原则的智能选择。以宁波电网为例，验证了在线校核系统的正确性及实用性。

The real-time and complicated operation mode of power grid lowers setting performance of setting value check method in particular situations. The setting value is calculated by county-level dispatch and checked by prefecture-level dispatch, and the prefectural-county setting performance needs some method to evaluate. To solve problems above, the paper investigates implementation scheme of online check system of integrated prefecture-county relay protection setting value. On the basis of introducing functional system of online check system of integrated prefecture-county relay protection setting value and access of online check data source, the paper presents a strategy of integrated prefecture-county online setting value check and em-phatically introduces intelligent identification of prefecture-county interface, layout and intelligent choosing of check principles. Taking Ningbo power grid as an example, the paper verifies correctness and practicality of online check system.
