Abstract

The invention discloses a harmonic resonance suppression system of a microgrid. The system comprises the microgrid which supplies power to equipment through a harmonic resonance suppression assembly.The harmonic resonance suppression assembly comprises a management chip MAX16046, and a double-feedback closed-loop current control method is built in the management chip MAX16046; the management chipMAX16046 reads real-time monitoring data, and the management chip MAX16046 controls enabling input and monitoring output of the microgrid; and the management chip regulates and suppresses the waveform of the output voltage of the micro-grid so that the waveform of the output voltage of the micro-grid is the same as the voltage waveform of the equipment, and the micro-grid supplies power to the equipment without an impact. According to the invention, the management chip MAX16046 regulates and suppresses the waveform of the output voltage of the microgrid so that the waveform of the output voltage of the microgrid is the same as the voltage waveform of the equipment, and the microgrid supplies power to the equipment without the impact.

Description

technical field [0001] The invention relates to the field of micro-grid technology, in particular to a harmonic resonance suppression system for a micro-grid. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. [0003] When the micro-grid supplies power to the equipment, it is difficult for the output current of the micro-grid and the voltage waveform of the equipment to maintain a positive wave of the same frequency. The impact is used in conjunction with the equipment; and the traditional microgrid lacks external protection devices, which has certain defects. Contents of the invention [0004] The object of the present invention is to provide a harmonic resonance suppression system of a microgrid to solve the problems raised in the above-mentioned background technology. [0005] In order...
