Abstract

The invention relates to a harmonic suppression device based on epitaxy delta controllable reactor connection. The harmonic suppression device comprises a first group of magnetically controlled reactors using epitaxy delta connection and a second group of magnetically controlled reactors using epitaxy delta connection, wherein the first group of magnetically controlled reactors and the second group of magnetically controlled reactors have the same type and are connected in parallel; and a three-phase iron core column of the first group of magnetically controlled reactors and a three-phase iron core column of the second group of magnetically controlled reactors have flat five-core structures. The three-phase iron core column of the first group of magnetically controlled reactors and an alternating-current working winding of the second group of magnetically controlled reactors employ the epitaxy delta connection way; an alternating-current working winding of the first group of magnetically controlled reactors uses delta forward connection as the epitaxy delta connection way; and the alternating-current working winding of the second group of magnetically controlled reactors uses delta reverse connection as the epitaxy delta connection way. According to the invention, with the connection ways of the working windings of the reactors, the harmonic performance can be improved to the great extent.

Description

technical field [0001] The invention relates to a harmonic suppression device, in particular to a harmonic suppression device based on the connection of an extensional triangle controllable reactor. Background technique [0002] For reactive power compensation in high voltage systems, the traditional method is to use circuit breakers as switching switches for capacitors. For the safety of devices, devices and power grids, it is generally required that the number of switching operations should not exceed 3 times a day (<1000 times) / year). This cannot meet the requirements of reactive power compensation for most grid systems where reactive power varies. The traditional reactive power compensation equipment is mainly synchronous condenser, fixed capacitor bank and mechanical switch switching capacitor bank, and these devices can meet a certain range of reactive power compensation requirements. However, the loss and noise of the synchronous condenser are relatively large, ...
