The invention relates to a wind-solar complementation new energy application experiment platform comprising a DC bus, a central controller, a solar power generation module, a wind power generation module, an energy storage module, a single-phase variable-frequency inversion module, a DC load module, a DC motor driving module, an LED lighting module and a three-phase grid-connected inversion module. The solar power generation module, the wind power generation module, the energy storage module, the single-phase variable-frequency inversion module, the DC load module, the DC motor driving module, the LED lighting module and the three-phase grid-connected inversion module are electrically connected with the DC bus respectively. The central controller communicates with the solar power generation module, the wind power generation module, the energy storage module, the single-phase variable-frequency inversion module, the DC load module, the DC motor driving module, the LED lighting module and the three-phase grid-connected inversion module through a wireless sensor network. A leading-edge, advanced, comprehensive and curricular and extracurricular integrated experiment and scientific research platform with sharing of undergraduates, postgraduates and doctors is constructed.

Description

technical field [0001] The invention belongs to the field of electrical engineering and electronic information, and in particular relates to an experimental platform for the application of wind and solar complementary new energy sources. Background technique [0002] The multifunctional smart microgrid is the development trend of terminal power supply for photovoltaic and other new energy power generation grids. However, the standard multifunctional smart microgrid cannot be directly used as a teaching platform, mainly due to the consideration of site and safety factors. Standard multifunctional smart microgrids all use new energy generation methods such as real photovoltaic power generation and wind power generation, which have high requirements for the installation site and cannot be installed directly indoors. These power supply methods adopted in the standard multifunctional smart microgrid have high system voltages, and for safety reasons, students cannot directly condu...

Problems solved by technology

[0002] Multi-functional smart micro-grid is the development trend of terminal power supply of photovoltaic and other new energy power generation grids, but the standard multi-functional smart micro-grid cannot be directly used as a teaching platform, mainly due to the consideration of site and safety factors

Standard multifunctional smart microgrids all adopt real photovoltaic power generation, wind power generation and other new energy power generation methods, which have high requirements on the installation site and cannot be installed directly indoors

These power supply methods adopted in the standard multi-functional smart microgrid system have high system voltage, and it is not possible for students to conduct practical training operations directly for safety reasons.

In addition, the power supply method adopted by the standard microgrid mode is too dependent on the intensity of sunlight and wind, so it cannot meet the requirements for teaching and system regulation
