Huanghua Port enters carbon neutrality ahead of schedule through technological innovation

Abstract

To improve the energy utilization rate and reduce the pollution of the port, the Huanghua Port uses technological innovation to enter carbon neutrality is proposed. According to the study of the working characteristics of a three-phase asynchronous motor, the copper loss and iron consumption of the motor are reduced, permanent magnets are embedded in the rotor to generate a magnetic field directly, and the kinetic energy and potential energy of mechanical operation are converted to power generation and recycled, and the braking power generation characteristics of the motor are used to complete power recovery. The tension of the upper and lower sides of the belt before it starts to rotate is equal, and the tensioning force should meet the starting requirements, and the working section of the belt carrying goods horizontally is divided and calculated according to the evenly distributed rollers until it runs at a uniform speed. According to its power consumption, calculate the cost of using an auxiliary generator to generate and connect electricity, use the power supply to supply the power demand, let the motor run in the rated load area as much as possible, reduce the voltage, and reduce the motor subway consumption, to improve the efficiency of the motor and realize the green energy saving of the port. The analysis of the results shows that: through this paper technical innovation of the whole process of all equipment comprehensive optimization, the port process line efficiency increased by 17.5% on average, equivalent energy saving of nearly 17%, the amount of work using time more reasonable, to ensure that the quality of work does not decline while reducing the waste of power resources, thus affecting the port efficiency improvement.
