摘　　要：热工保护系统运行中发生误动及拒动的主要原因是由于系统故障、元器件老化、线路连接不牢以及人为因素导致的。针对这些问题提出一些防止热工保护误动、拒动的对策,分析了一些电厂热工保护误动及拒动案例,希望最大程度地减少热工保护误动、拒动。The main reasons for the misoperation and rejection of the thermal protection system are due to system failure, aging of components, poor line connection and human factors. In view of these problems, we propose some countermeasures to prevent the thermal protection from misoperation and rejection, and analyze some cases of misoperation and rejection of thermal protection in power plants in the hope of minimizing the misoperation and rejection of thermal protection.
