Abstract

The invention discloses a chain SVG cooling system control device and method. The device includes: a temperature detection module installed on the edge-gate bipolar transistor IGBT core of the chain link unit of the chain SVG, which is used to detect the temperature of the IGBT core in real time and generate a temperature signal; a temperature signal conversion module is used to detect according to the temperature The temperature signal generated by the module determines the temperature of the IGBT core; the control module is used to control the air volume of the cooling fan according to the current temperature of the IGBT core. The present disclosure provides devices and methods, which can track the IGBT core temperature in real time, ensure that the chain link unit of the chain SVG works at the optimal temperature state, and improve the highest work efficiency; it can effectively reduce the number of starts of the fan, increase the service life, and improve the performance of the fan. Work efficiency, reduce energy loss, and can control the fan speed, reduce the noise caused by fan operation.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a cooling system control device and method for a chained SVG. Background technique [0002] The cooling system of the current chained SVG (Static Var Generator) is mostly an air-cooled circulation system, and only a very small number of large-capacity devices use a water-cooled circulation system. However, most of the air-cooled circulation system control methods are relatively simple, which directly control the start and stop of the fan, and then cool the chain link unit through the air duct. The fan power selection is mostly designed according to the maximum power consumption of the chain link. [0003] There are two ways to control temperature in the prior art: the first is automatic control, when the device detects that the temperature of the link unit exceeds the set value, the fan is started, and when the temperature of the link unit is lower than the set value, the fan is sto...
