The invention relates to the technical field of power electronic conversion, and provides an off-grid operation control method for an active triple harmonic injection matrix converter. The method comprises the following steps: controlling and adjusting the output of a rectifier according to the first input information of the active tripe harmonic injection matrix converter and the obtained rectification control rule; and controlling to obtain triple harmonic injection reference current according to the output voltage reference of the active triple harmonic injection matrix converter and the obtained triple harmonic injection control rule, obtaining a modulation signal and controlling the output voltage of the active triple harmonic injection matrix converter. According to the off-grid operation control method for the active triple harmonic injection matrix converter, the requirement for maintaining the load voltage under different load conditions under the off-grid operation conditionis met, and the method has important significance in guaranteeing the high efficiency and good dynamic performance of the active triple harmonic injection matrix converter under the off-grid operationcondition.
Description
technical field [0001] The present invention relates to the technical field of electric power technology transformation, and more specifically, relates to an off-grid operation control method of an active third harmonic injection matrix converter. Background technique [0002] With the rapid development of power electronics technology, it has been widely used in new energy development and energy saving, and the power converter as the core is also widely used in various AC-AC conversion occasions. [0003] In distributed power generation occasions such as wind power generation systems, diesel power generation systems, and micro gas turbine power generation, the voltage amplitude and frequency of the input side power supply usually change, while the output is required to be a three-phase voltage with a fixed amplitude and frequency. Therefore, this type of distributed power supply cannot be directly connected to the load, and must be connected to the power supply and the load ...
