Natural Gas Storage And Distribution Station Pressurized Plant Control System Design

An economic field bus control system which is composed of programmable logical controller(PLC), industrial control personal computer is designed in this thesis according to the development of field bus control system of natural gas compressor sets. The architecture, hardware configure and software system of the control system are designed in this paper. The control software is designed and debugged used the King View kit of Beijing Asia control Automatic software Company and Step 7 industrial control software of Siemens Company in Windows XP. A field bus control system based the Profibus protocol is built to control the nature gas compressor sets, and used the S7-300 PLC of Siemens Company, the devices of Profibus and industrial control computer. Auto-control and monitor system of the nature gas compressor sets has been build, and the press, the flux, the temperature and other status parameters of the compressed and compressing nature gases or air can be monitor online in the center operation room. The nature gas compressor sets can be stable and security running by this field bus control system. The method to integrate the measurement, and control, and field bus network system is universal to design a field bus control system. This paper is an sample to solve these problems such as how to select the hardware, how to design software and how to choice the sensor etc. This method can meet the future requirement and make the system have good qualities easily, economy and stable.
