Research And Design Of Process Control System In The Chief Transformer Substation Of Petrochemical Equipment

The process of chief transformer substation of chemical equipment is the process that transform high voltage grade electrical energy sources to low voltage grade and redistribute electrical energy sources. It involves the measurement and the control of many process parameters, such as voltage, electrical current, efficiency power, invalid power, power factor and so on. It is the most pivotal and important to control the low voltage grade of chief transformer substation, which pledges the running production and quality of electrical source supply. So, it is valuable that automatic inspection and control are brought into effect in the process in the chief transformer substation of chemical equipment.Article referred to some recent designs of automatic control production-process system of chief transformer substation in CHINA. And a series of control systems had been designed for the 110kV chief transformer substation of petrochemical company, DAQING. Firstly, the measurements in locals (CT and PT) and control equipment are designed according to the factors of technology and price. Then, the distributed computer control is designed based on CAN-BUS field-bus according to the point of centralize surveillance and distributed control.Finally, system software is designed, then the measurement and control system are used successfully in the chief transformer substation. At present ,the system runs normally and supply energy reliably.
