Description

technical field [0001] The invention relates to a high-simulation solar battery simulator, which belongs to the technical field of photovoltaic power generation equipment. Background technique [0002] In photovoltaic grid-connected power generation, it is often necessary to carry out simulation operation tests on electrical components such as photovoltaic inverters in order to collect their operating parameters and performance, or to simulate the operating status of the photovoltaic power supply network. In these operations, in order to fit the actual operation of the equipment as much as possible, it is necessary to use a professional analog solar battery power supply, and most of the power supplies currently used are directly obtained by performing multiple rectification transformations on the AC power supply. Although the power supply in the output state of the solar battery can meet the needs of use to a certain extent, there is still a huge gap from the real power gene...

[0002] In photovoltaic grid-connected power generation, it is often necessary to carry out simulation operation tests on electrical components such as photovoltaic inverters in order to collect their operating parameters and performance, or to simulate the operating status of the photovoltaic power supply network. In these operations, in order to fit the actual operation of the equipment as much as possible, it is necessary to use a professional analog solar battery power supply, and most of the power supplies currently used are directly obtained by performing multiple rectification transformations on the AC power supply. Although the power supply in the output state of the solar battery can meet the needs of use to a certain extent, there is still a huge gap from the real power generation state of the solar battery. There is a large deviation between them, so in view of this situation, it is urgent to develop a high-simulation solar cell simulation power supply to meet the needs of actual use
