Research and Application of Reactive Power Compensation on High Power Scrap Crusher in Production Line

At present, there are many power quality problems in the production lines of domestic factories, such as the drop of grid voltage amplitude, the low power factor in the operation of motor, etc. In order to ensure the power quality of the power grid, the SVG system is designed based on the scrap crushing production line of a steel enterprise in Anhui province. The design has been combined with the actual working conditions of the site. A dynamic reactive power compensation device for high power production line is proposed, and the relevant parameters of the system are calculated. Finally, through MATLAB simulation and field application tests, the starting process of the high-power motor and the compensation effect under different load conditions is compared, the results are in agreement with the theory, and the correctness of the design is verified.
