Abstract

The invention discloses a second harmonic elimination device of a power transmission network. The device comprises an outer frame, wherein the outer frame comprises a top layer structure, a bottom layer structure and a main body part arranged between the top layer structure and the bottom layer structure, wherein the main body part comprises a cabinet body and a cabinet door; a grid side current and voltage acquisition module, a load side current and voltage acquisition module, a passive filter acquisition module, a parallel reactor, an active filter detection module and a touch screen controller are arranged in the cabinet body; the grid side current and voltage acquisition module sends a detected signal to the passive filter acquisition module; the load side current and voltage acquisition module sends a detected signal to the active filter detection module; the touch screen controller is connected with the parallel reactor, the passive filter acquisition module and the active filterdetection module. The device can offset electronic harmonic, and active filtering can realize dynamic compensation of reactive power besides filtering out of harmonic.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a second harmonic elimination device for a transmission network. Background technique [0002] With the development of the power industry in recent years, in the power system, the power grid and users use a large number of nonlinear equipment, and the harmonic problems caused by it are becoming more and more serious. The harmonics generated by nonlinear equipment can usually cause distortion of the supply voltage. [0003] At present, there is a lack of a device on the market that can eliminate harmonics generated in the power system, resulting in more and more harmonic pollution, which not only threatens the safe, stable and economical operation of the power system, but also directly affects the quality of power supply. The electrical environment has brought a great impact. Solving the harmonic problem in the power system has very positive significance for improving the ...
