摘　　要：主要介绍了田湾核电站二期SPPA-T2000系统(正常运行仪控系统)在主/从AP(自动处理器)同时故障情况下,为减少或避免对机组正常运行状态造成的扰动,通过普查SPPA-T2000系统的软件逻辑,深入分析总结控制逻辑信号变化对系统状态变化的影响,制定相应的控制优化策略的方式方法。以部分控制优化事例,详细介绍了故障发生时信号的变化,对系统的影响,以及所采取的优化措施。经过理论分析和实践,有效增强了正常运行仪控系统抵御双AP故障的能力,降低了故障情况下对系统和机组安全稳定运行的不利影响。This passage mainly introduced the control optimization strategy of Tianwan nuclear power plant SPPA-T2000system with dual redundancy AP(automatic processor)fault,by comprehensive review control logic of SPPA-T2000 system,and in-depth analysis summarizes the effect of signal changes on the system state.The dual redundancy AP fault effects and the control optimization strategies are further illustrated with examples.Through theoretical analysis and practice,the ability of resisting dual redundancy AP fault for SPPA-T2000 system is effectively enhanced,and the adverse influence of the safe and stable operation for SPPA-T2000 system is reduced.
