AI Technical Summary

Technical Problem

In the equipment room of a substation, when multiple cooling fans are configured, the traditional frequency conversion control system lacks coordinated control, resulting in poor overall temperature control and high energy consumption.

Method used

A variable frequency control method and system is adopted to calculate the start-up and stop temperatures of the fans by real-time monitoring of indoor and outdoor temperatures and heat generation power of the equipment, and dynamically adjust the target power frequency and priority of the fans to achieve coordinated control of multiple fans.

Benefits of technology

It improves temperature control, reduces energy consumption, extends the service life of the fan, balances the fan's workload, and reduces maintenance costs.

Abstract

The invention provides a frequency conversion control method for a cooling fan of a substation equipment room, a plurality of fans are arranged in the equipment room, each fan is driven by a frequency converter, and the frequency conversion control method comprises the following steps: monitoring the indoor temperature and the outdoor temperature of the equipment room in real time; based on the indoor temperature, the outdoor temperature, the total heating power of the indoor equipment, the air specific heat capacity and the rated ventilation quantity of the whole set of fans, the starting temperature and the stopping temperature of the fans are obtained through calculation; and when the indoor temperature reaches or exceeds the starting temperature, a fan starting control strategy is executed. The invention further provides a corresponding system. According to the invention, a plurality of indoor fans can be cooperatively controlled, the temperature control effect is improved, the energy consumption is reduced, and the service life of equipment is prolonged.
