SVG control device based on environment adaptation

Abstract

The invention relates to an SVG control device based on environment adaptation, and belongs to the technical field of electric energy quality and reactive power control. The SVG control device is characterized in that the SVG control device comprises an SVG controller, a display device, a detection module, a heater, a dehumidifier and a draught fan; the SVG controller comprises a communication module and an environment adaptation control module, wherein the communication module is in communication with SVG equipment, the display device and a data server which are mounted in an SVG cabinet, andthe environment adaptation control module controls the heater, the dehumidifier and the draught fan; a PLC and a digital signal processor are mounted in the environment adaptation control module; andthe detection module detects the environment temperature and humidity and the air pressure state in the SVG cabinet to form detection data, the digital signal processor in the environment adaptationcontrol module processes the detection data sent from the detection module and then conducts corresponding control over the SVG equipment and / or the heater, the dehumidifier and the draught fan, the environment in the SVG cabinet is adjusted, and the safety of the SVG equipment is ensured. The SVG control device can decrease the failure rate of the SVG equipment.

Description

technical field [0001] The invention relates to an SVG control device based on environment self-adaptation, and belongs to the technical field of power quality and reactive power control. Background technique [0002] With the vigorous development of new energy sources, reactive power compensation equipment has been applied in a wide range. At present, SVG equipment (static var generator) with air-cooled control is routinely used to operate at the rated fan speed, which cannot solve condensation. , Negative pressure and other phenomena lead to reduced insulation of SVG equipment, severe corrosion, and even short-circuit tripping, which will cause a great impact on the power grid. At the same time, the long-term maintenance of the rated speed of the fan will cause the service life of the fan to be reduced and energy waste due to long-term full-load operation. [0003] How to make the SVG equipment automatically change the speed of the fan according to the environment, turn on...
