Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to a harmonic resonance suppression system. Background technique [0002] Microgrid, also translated as 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. The proposal of microgrid aims to realize the flexible and efficient application of distributed power, and solve the problem of grid connection of distributed power with a large number and various forms. The development and extension of microgrids can fully promote the large-scale access of distributed power sources and renewable energy, and realize the highly reliable supply of various energy forms for loads. In the transition of the smart grid, there will be a large number of harmonic resonances in the micro-grid. In order to maintain the stable operation of ...

Problems solved by technology

With the continuous progress and development of power electronic technology, the power electronic equipment in the system has been widely used. At the same time, the nonlinear load is increasing, and the high-voltage direct current is popularized, which leads to the increasingly serious harmonic problem of the power system. This paper analyzes on this basis The causes of harmonic problems in the power system and the harm caused, and then according to the causes of harmonics, various technologies and suppression effects for harmonic suppression are proposed. However, there are still various harmonic resonance suppression systems on the market. kind of question

[0003] For example, the authorized announcement number is CN112234647A, which discloses a micro-grid harmonic resonance suppression system. Although it realizes the management chip MAX16046 to regulate and suppress the waveform of the output voltage of the micro-grid, so that the waveform of the output voltage of the micro-grid is equal to the voltage of the equipment The waveforms are the same, and the microgrid can provide power supply for the equipment without impact, but it does not solve the problems that the existing harmonic resonance suppression system cannot realize detection and cannot realize multiple harmonic resonance suppression. Therefore, we propose a Harmonic resonance suppression system
