AI Technical Summary

Technical Problem

In existing capacitor heat dissipation control, the fixed-spacing heat dissipation structure leads to excessive fan energy consumption when dealing with frequent fluctuations in grid load, and the energy consumption increases significantly under high load, while the air duct resistance causes energy waste under light load or normal load.

Method used

Through a group-independent control architecture, the spacing between capacitor units is dynamically adjusted based on the real-time operating data of the capacitor regulating group. The spacing is shortened under high load conditions to increase local wind speed, and widened under low load conditions to reduce wind resistance. The spacing settings are optimized by combining historical operating data to achieve adaptive heat dissipation adjustment.

Benefits of technology

While ensuring heat dissipation safety, the overall energy consumption of the fan was reduced, the system's accuracy and robustness in identifying changing operating conditions were improved, frequent false switching caused by instantaneous load fluctuations was avoided, and the energy efficiency and stability of the equipment were enhanced.

Abstract

This application discloses a capacitor heat dissipation control method, device, system, and medium, belonging to the field of power equipment heat dissipation control. The method involves: collecting and determining the minimum and maximum heat dissipation distances of corresponding capacitor adjustment groups based on the current operating data of each capacitor unit; determining the load condition of each capacitor adjustment group based on the current operating data; controlling the distance between capacitor units in the first capacitor adjustment group where the load condition is a high-load heat dissipation condition to the minimum heat dissipation distance, thereby increasing the local wind speed between the corresponding capacitor units; and controlling the distance between capacitor units in the second capacitor adjustment group where the load condition is not the high-load heat dissipation condition to the maximum heat dissipation distance or a preset initial heat dissipation distance, thereby reducing the local wind resistance between the corresponding capacitor units. Therefore, by implementing this application, the problem of excessive fan energy consumption in the capacitor heat dissipation control process can be solved.
