advanced online monitoring of fars province gas pressure reduction stations based on distributed control system of pcs7

monitoring is an essential and inseparable tool for every industrial automation system.  in advanced monitoring, in addition to representation of the process conditions, fast identification and removing of the faults in different critical parts of the system is indispensable. distributed control systems (dcs) are an integral part of the current automation systems and hence, advanced monitoring techniques need to be effectively adapted and implemented in these control systems.  this paper presents a novel method for implementation of the advanced online monitoring on the pcs7. model of the gas station is first developed. the effectiveness of the model is evaluated using the model data of a real gas pressure reduction station under various operating conditions. advanced monitoring is then implemented for this station. the real-life results demonstrates that the presented method can effectively detect the system faults.
