Low-voltage reactive automatic compensation apparatus under multi-circuit reactive compensation control

Abstract

The invention discloses a low-voltage reactive automatic compensation apparatus under multi-circuit reactive compensation control, and belongs to the technical filed of the electric power system. The low-voltage reactive automatic compensation apparatus comprises a stainless steel shell, wherein a liquid crystal display screen is arranged on the outer wall of the stainless steel shell; mounting holes are formed in the left and right ends of the outer wall of the stainless steel shell respectively; a bottom shell is arranged at the bottom of the stainless steel shell; a machine core plate is arranged in an inner cavity of the bottom shell; electric reactors are uniformly arranged on the top of an inner cavity of a multi-circuit reactive compensation controller; non-contact switches are arranged at the bottoms of the electric reactors; three-phase electric power capacitor groups are arranged at the bottoms of the non-contact switches; a filtering capacitor is arranged at the bottom of the inner cavity of the machine core plate; and a protection switch is arranged on the right side wall of the inner cavity of the machine core plate. The low-voltage reactive automatic compensation apparatus is high in speed and capable of realizing data acquisition and intelligent data processing in real time; the multi-circuit reactive compensation control is adopted, so that the compensation range is enlarged; a man-machine conversation interface is user-friendly; and in addition, the low-voltage reactive automatic compensation apparatus is convenient to use and low in cost.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a low-voltage reactive power automatic compensation device under multi-loop reactive power compensation control. Background technique [0002] With the development of power production, the requirements for power grid power supply are getting higher and higher, mainly reflected in the higher and higher requirements for power distribution measurement accuracy, and more and more monitoring indicators. Power automatic compensation devices, most of them have the following shortcomings: incomplete functions, poor precision, low degree of automation, slow compensation response time, although the country has disclosed an automatic dynamic reactive power compensation device, using industrial single-chip computers For detection and control, it can automatically detect the best input point and control the opening and closing of the high-speed switch, which improves the compensation re...
