Design Of Operation Monitoring System For The Natural Gas Compressor Unit

With the rapid development of domestic natural gas industry,the natural gas compressor unit,as the key pressurization equipment in the process of gas production,has been widely used.The natural gas compressor unit has the characteristics of large investment,complex structure and years of continuous operation,etc.The unit must have high reliability.It is very important to equip the natural gas compressor unit with a set of reliable operation monitoring system.The operation monitoring system can real-time monitor the running parameters of each part.Any abnormal parameters can generate an alarm or machine halt timely.So the system can effectively prevent the occurrence of serious equipment failure and effectively reduce the labor intensity and improve the equipment management level.Firstly the paper expounds the importance of natural gas compressor unit and the monitoring system in oil and gas industry,and summarizes the structure,principle,type,and application in natural gas compressor unit of computer supervisory and control system.On the basis of the analyzing the structure,working principle of integral natural gas compressor unit,the paper designs the basic principles,general specification,the overall design scheme,and design steps of the natural gas compressor monitoring system,combined with practical engineering requirements for monitoring and control systemNatural gas compressor monitoring system including two parts,that is the lower computer system and the upper system.Firstly lower computer system includes hardware design and software design.In the hardware design the hardware selection is in the first place,and then is the principle diagram of the system of electrical design and installation.Software design includes the design of the PLC control program and touch screen configuration,which realizes locally monitoring of logic control and human-computer interaction function of natural gas compressor.Through the communication Settings and configuration software application development,the paper realizes the upper machine system for remote monitoring of natural gas compressor unit,which satisfies practical needs.
