Abstract
The invention discloses an SVG fan energy consumption reduction method. A fan is set to run at a rated rotating speed. The method comprises the following steps that A, a temperature value of a module in an SVG is detected; B, the detection temperature value in the step A is compared with the set temperature value; C, if the detection temperature value is smaller than the set temperature value, a hot alternative scheme is input to close all fans, or a frequency changer segmented speed reduction scheme is adopted; and D, if the detection temperature value is larger than or equal to the set temperature value, the running state of the fans is maintained. Under the condition that equipment does not need to be greatly modified, the hot alternative scheme is adopted to enable the fans to be shut down when the SVG body normally runs, and energy consumption of the fans is saved. The scheme that a frequency changer controls the fans is adopted to determine fan air outlet amount needed when a power unit is at the different temperatures, the frequency changer controls the rotating speed of the fans to reach the set air outlet amount so as to save power consumption of equipment; and through calculation, more than 50% of equipment body consumption can be saved.
