摘要
从热控保护防误动和防拒动原则出发,对热工保护误动及拒动原因进行了分析和总结,针对DCS系统硬件故障及现场设备故障可能对机组保护系统产生的影响,提出保护逻辑改进完善方案。对提高DCS系统的整体可靠性,保证机组安全、稳定运行具有一定的参考价值。
From the thermal control protection and anti-anti-mal-tripping principle,to the thermal protection of the reasons for malfunction,and refused to move were analyzed and summarized for the DCS system hardware failures and on-site equipment failures may be the impact of crew protection system is proposed to protect logic to improve and perfect the program.Improving the overall reliability of DCS system to ensure the unit safe and stable operation has a certain reference value.
