The invention discloses a multifunctional power tuning and filtering system and method. It includes a filter module and a control system. The filter module includes a magnetron reactor, a resistor, and several switchable capacitors. filter, the filtering module is provided with a current transformer and a voltage transformer, and the magnetically controlled reactor is provided with a temperature sensor, and the control system includes an ARM single-chip microcomputer, a man-machine operation panel and a background management server, and the described ARM single-chip microcomputer and The filtering module is connected, the man-machine operation panel is connected with the ARM single-chip computer, and the ARM single-chip computer is connected with the background management server. The beneficial effects of the invention are: greatly reducing the harmonic content of the power grid, reducing power consumption, and improving the reliability of equipment and other electrical components; the resonance point can be adjusted independently, the air cooling can be started, the capacitive reactance can be increased, and faults can be reduced.

Description

technical field [0001] The invention relates to the related technical fields of harmonic control, remote power data acquisition and monitoring technology, and is specially used for low-voltage harmonic filtering devices of 5 / 7 / 11 / 13 orders of low-voltage power grids, and is suitable for smelting, frequency conversion, steel rolling, rectification, and inverter The environment of arc welding equipment, etc., especially refers to a multifunctional power tuning filter system and method. Background technique [0002] The traditional LC single-tuned filter is mainly composed of three parts: resistors, capacitors, and inductors, and is placed next to the device that generates harmonics in the power grid. The harmonic current is bypassed through a single-tuned filter circuit and a high-pass filter branch. The advantages are simple structure and low cost, and it is currently the most commonly used method for harmonic control and power quality compensation. [0003] The early single...
