Abstract

The invention provides a photovoltaic cell simulation system and a simulation method for the same. The system comprises a man-machine interface assembly, a power supply device, a control core and a cell simulation device, wherein the man-machine interface assembly is connected with the control core through a communication assembly; the power supply device is connected with the man-machine interface assembly, the control core and the battery simulation device; and the battery simulation device is connected with the control core and is controlled by the control core. When the system is in use, the man-machine interface assembly is used for transmitting setting command information to the battery simulation device, and the control core is used for controlling voltage and current output of thebattery simulation device according to a command after receiving the information; and meanwhile, the control core is used for acquiring operation parameters of the input voltage and current of a loadinverter for the control core of the system, computing the maximum power point tracking (MPPT) efficiency of a load, feeding back to the man-machine interface assembly for displaying, and providing reference bases for the design of an MPPT algorithm for a user.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic power generation simulation technology equipment, in particular to a photovoltaic cell simulation system and a simulation method for the system. Background technique [0002] Since the second half of the 1990s, with the strong support of the state, solar photovoltaic power generation has entered a period of rapid development. The average annual growth rate of solar cells in the last 10 years and the last 5 years is 41.3% and 49.5% respectively. In our daily life, we can often see some applications powered by solar cells, such as solar water heaters, solar street lights, solar-powered calculators, and even mobile phones. At the same time, due to the development of grid-connected technology, grid-connected power generation The proportion of applications is increasing. Solar photovoltaic power generation is playing an increasing role in the energy structure. The grid-connected inverter is an impo...

Problems solved by technology

The research and test of the inverter needs to be connected to the solar panel, but because the quality parameters of the solar panels produced by various manufacturers are not the same, in different application systems, the parameters and configuration of the solar panel are fixed and cannot be changed , the most important thing is that its test is limited by weather changes and geographical environment, so it brings great inconvenience to the test research of the inverter
