在调度员培训仿真系统（ DTS）中，继电保护仿真的准确性、时效性以及维护便利性是仿真系统重要的评估指标。当前主流的保护仿真有定值判断与逻辑判断两种技术思路，两者都具备各自的优势与不足，应用的情景也不尽相同。在华北要求多级调度、调控一体化仿真背景下，为确保培训系统保护仿真的时效性与准确性，文中对传统的单纯定值与逻辑判断进行改进，采用基于逻辑判断搜索的定值判断混合仿真技术。研究表明，该仿真技术适用面广、可靠性好，可满足DTS系统对多级电网调度调控仿真需求。

In dispatcher training simulation system ( DTS) , accuracy, timeliness and convenience of maintenance are important evaluation indexes of relay protection simulation.Current mainstream methods of protection simulation, which use fixed value judgment or logic judgment, have their advantages and disadvantages, and their application sce-narios are also different.Under the background of multistage scheduling and control integration simulation in China Northern Power Grid, the paper improves conventional single fixed value or logic judgment methods and adopts hybrid fixed value simulation technology based on logic judgment to ensure the timeliness and accuracy of protection simula-tion training system.The research results show that the simulation technology have wide application and good reliabili-ty, which can adapt to the requirement of multistage grid scheduling and control simulation.
