Vector Control of Brushless DC Motor Based on Super-twisting Sliding Mode Control and Optimal Current Vector BIAN Zhenzhen, LI Fengsheng 2023, 50 (6):  14-17.  Abstract ( 474 )   Save The speed loop of traditional brushless DC motors is easily affected by changes in internal and external parameters during operation,resulting in problems such as large commutation torque ripple. To solve these problems,space vector pulse width modulation （SVPWM） is used instead of PWM modulation. A control scheme is proposed,which uses fast super-twisting sliding mode control for the speed loop instead of PI control and injects optimal current vector into the q-axis current. By building a simulation model and analyzing the simulation results,it can be seen that compared to the traditional control strategy,this method can effectively reduce startup overshoot,improve dynamic response capability,and suppress commutation torque ripple.

Application of Integrated Skid-mounted Oil-water Purification and Separation Equipment in Natural Gas Processing Plants LI Hongjia, YANG Zhixiong 2023, 50 (6):  18-21.  Abstract ( 483 )   Save The oily wastewater in a natural-gas processing plant mainly comes from natural gas dewatering,pigging effluent and bottom water of storage tanks. The main pollution factors are petroleum and organic pollutants. The amount of oily wastewater produced is about 30 m3 per day,oil in water is flammable and volatile condensate light oil,the oil content in water is affected by many factors,such as liquid coming from sea pipe,fluctuation of upstream and downstream flow,etc,the oil content fluctuates randomly from 0 to 100%,the existing device has a large oil-water separation load,and the treatment effect is not up to the standard. After adopting the integrated skid-mounted oil-water purification and separation equipment on site,the oily wastewater treatment effect is good and meets the design requirements. It is of great significance to the stable operation of the natural-gas processing plant,upstream and downstream production processes,and also provides reference for the process modification work under similar working conditions.

Application of Low Nitrogen Burner+Exhaust Gas Recirculation Technology in Energy Saving and Emission Reduction Renovation of Thermal Medium Boilers LI Jiucheng 2023, 50 (6):  22-24.  Abstract ( 474 )   Save The thermal medium boiler is the core equipment for oil and gas treatment. At present,the thermal medium boilers in operation in offshore oil and gas fields,FPSOs and terminal treatment plants are characterized by high energy consumption and high emissions. The nitrogen oxides discharged exceed the emission standard limit of atmospheric pollutants by≤100 mg/Nm³. In order to overcome the drawbacks of high energy consumption and emissions in boilers,and to address the frequent start-stop issues of the equipment,the concepts of emission reduction,energy conservation,and carbon reduction have been integrated into the low nitrogen transformation plan,breaking through the conventional approach to achieve multiple benefits. After the completion of the low nitrogen burner and exhaust gas recirculation transformation technology for the thermal medium boiler,the hot oil system has been operating stably since its commissioning,with nitrogen oxide emissions less than 30 mg/Nm³. The economic and social benefits are very significant. References | Related Articles | Metrics

Energy Consumption Analysis and Energy-saving Technology Application of Offshore Platform Lighting System REN Linpeng, SONG Liwei, Meng Caizhi 2023, 50 (6):  40-42.  Abstract ( 482 )   Save Offshore oil platform is a key facility for offshore oil and gas exploitation and processing. The offshore oil platform is in continuous operation and its lighting system is also in continuous operation. Although the continuous operation mode of lighting fixtures in offshore oil and gas fields ensures the reliability of lighting,some lighting fixtures do not need to operate continuously under sufficient sunlight,resulting in unnecessary energy consumption during certain time periods. According to the functional principles of the lighting system,combined with the lighting requirements of workplaces and the actual usage of lighting fixtures,the research and analysis on energy conservation and consumption reduction of lighting fixtures were conducted from several aspects,and targeted measures were taken. Energy conservation optimization,automation upgrade,and remote monitoring transformation were carried out on the lighting systems of offshore platforms and floating oil storage vessels,achieving energy conservation and consumption reduction,intensification,and automation monitoring.
