Abstract

The invention discloses a microcomputer harmonic elimination device, which comprises a power supply module, a central processing module, a voltage acquisition module, a harmonic elimination module, a communication module, a clock module, a display module, a button module, an alarm module and a storage module. The beneficial effect of the invention is: by connecting the voltage acquisition module, the communication module, the display module and the alarm module with the central processing module respectively, so that the collected voltage can transmit data and signals with the external equipment in time through the communication module, and through the display The module displays in real time, and sends an alarm signal through the alarm module, which is convenient for timely observation and processing of faults. The resonance elimination module composed of resonance elimination elements and relays connected in parallel is connected to the central processing module, so that overvoltage, magnet resonance and grounding can be quickly distinguished Which one of the faults is convenient for timely elimination of resonance.

Description

technical field [0001] The invention relates to the technical field of harmonic elimination devices, in particular to a microcomputer harmonic elimination device. Background technique [0002] In the power system, magnet resonance occurs frequently, and overvoltage will be generated during resonance, which seriously threatens the safety of the power system. Overvoltage phenomenon can occur in any system of 3~220 kV, especially in power grids of 35 kV and below, almost all system overvoltage phenomena are caused by ferromagnetic resonance, and the overvoltage caused by ferromagnetic resonance lasts For a long time, it may even exist for a long time. At present, the solution to ferromagnetic resonance is to install a resonance elimination device. The existing resonance elimination device is inaccurate in judging the resonant frequency, and cannot distinguish between overvoltage, magnet resonance and ground fault, and cannot Quickly eliminate resonance. [0003] Aiming at th...
