Description

technical field [0001] The invention relates to the technical field of harmonic elimination equipment, in particular to a microcomputer harmonic elimination device capable of remote monitoring. Background technique [0002] Most of the systems below 35kV in my country adopt the power supply neutral point ungrounded operation mode, and the primary winding of the electromagnetic voltage transformer on the bus becomes the only metal channel for the neutral point ungrounded power grid to the ground, and the charging and discharging path of the relative ground capacitance of the power grid must pass Primary winding of voltage transformer. When a single-phase grounding occurs in the system, the fault point will flow capacitive current, the voltage of the sound phase will rise to the line voltage, and the charge corresponding to the line voltage will be charged on its ground capacitance. Once the ground fault disappears, the current path is cut off, and the non-grounded phase must ...

Problems solved by technology

However, no matter whether it is the second harmonic elimination or the primary harmonic elimination, remote monitoring cannot be carried out. When the harmonic elimination data needs to be obtained, the only way to read the data is to check the resonance eliminator at the place where the resonance eliminator is installed or artificially Carry out corresponding operations on the tuner to control the work of the tuner
