摘　　要：为了正确使用Emerson公司Ovation品牌DCS(Distributed Control System,集散控制系统)中的温度保护算法TEMPHIGH,需要对其进行研究。对算法的内部逻辑进行理论分析,认为存在隐患:在温度设定值低于环境温度时,保护信号可能无法得到触发。然后模拟现场实际控制要求,给出相应的控制组态后开展仿真试验。仿真结果证明了理论分析的正确,因此在使用此算法时应注意避免此问题。In order to correctly use the temperature protection algorithm TEMPHIGH in Emerson’s Ovation brand DCS(Distributed Control System),it needs to be studied.Through theoretical analysis of the internal logic of the algorithm,it is considered that there is a hidden danger:when the temperature setting value is lower than the ambient temperature,the protection signal may not be triggered.Then simulate the actual control requirements on site,give the corresponding control configuration,and carry out the simulation test.The simulation results prove the correctness of the theoretical analysis.The simulation results prove the correctness of the theoretical analysis.Therefore,care should be taken to avoid this problem when using this algorithm.
