Description

Technical Field

[0002] A static var generator (SVG) is a highly reliable, efficient, pollution-free, high-voltage, high-power power quality management device. As an excellent reactive power compensation device, it is widely used in various renewable energy power stations to provide reactive power capacity and improve the power quality of renewable energy stations.

[0003] As a high-power device implemented using an insulated gate bipolar transistor (IGBT), cooling and heat dissipation are crucial during operation. The SVG cooling system provides heat exchange in a relatively small time and space, with excellent heat dissipation performance, ensuring SVG stability.

Most cooling system controllers are implemented using a combination of programmable logic controllers (PLCs), which have limited anti-interference and reliability. This leads to widespread problems such as abnormalities causing the cooling system to stop inadvertently, and inaccurate temperature control leading to SVG shutdowns. Utility Model Content
