Abstract

The invention discloses a modular multifunctional MMC type topology universal experiment platform and a method thereof, and belongs to the technical field of power electronics. The experiment platformis composed of modular hardware. A bridge arm module can be converted into a shaping circuit and a conduction switch circuit; a power supply module comprises an auxiliary power supply module and an AC-DC side power supply port, can be connected with an AC source and a DC source, and can also be connected with a plurality of universal experiment platforms to satisfy the demands of a multi-terminalcooperative control experiment. A control module comprises a master controller and a slave controller. With the platform, various topological experiments of MMC, HMMC, AAMC, HCMC, modular multilevelDC-DC converters and the like can be realized, and the purpose of utilizing one platform to carry out various topological experiments is achieved. The modular multifunctional MMC topology general experiment platform provided by the invention has the advantages of simple operation, multiple functions, strong universality, strong expansibility, high safety and the like, and is beneficial to accelerating the conversion of scientific research achievements.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a modular multifunctional MMC topology universal experiment platform and a method thereof. Background technique [0002] High-voltage direct current transmission (HVDC) has the advantages of high transmission efficiency, large capacity, variable power flow, easy integration of distributed power sources, and fewer large-scale energy storage devices. It has gradually become the preferred solution for long-distance, cross-regional, and large-capacity power transmission. Modular Multilevel Converter (MMC) has gradually become one of the most promising converters in HVDC systems due to its high modularity, good output waveform quality, and low device switching frequency. Due to the high cost of the full-bridge MMC, and the lack of DC fault ride-through capability of the half-bridge MMC, on the one hand, in order to have a certain DC fault ride-through capability,...
