Problems solved by technology

[0005] With the vigorous development of new energy technology, my country's technical colleges have begun to add new energy majors in recent years to train professional and technical personnel urgently needed by the market. The corresponding teaching process requires a solar power generation training system. Although there are some solar power generation experiments on the market platform, but they are all off-grid power generation, no grid-connected power generation experimental system has been seen

Abstract

The invention discloses a photovoltaic grid-connected generation training device. The device comprises a photovoltaic array system, a uniaxial tracking system, a junction box and a photovoltaic grid-connected generation teaching training platform, wherein the photovoltaic array system is arranged on the uniaxial tracking system; the photovoltaic array system and the uniaxial tracking system are connected with the junction box; and the junction box is connected with the photovoltaic grid-connected generation teaching training platform. The photovoltaic grid-connected generation teaching training platform comprises an inverter, wherein the inverter can be connected with the public power grid. The photovoltaic grid-connected generation training device can finish photovoltaic generation and synchronous grid-connected experiment as well as teaching demonstration, and help students to understand the principle of a solar grid-connected generation system and study engineering practical application performance.

Description

technical field [0001] The invention relates to experimental teaching equipment, in particular to a practical training device for photovoltaic grid-connected power generation. Background technique [0002] Solar energy is a clean and renewable new energy source, which is more and more favored by people. Obtaining electricity from solar energy requires photoelectric conversion through solar cells. It is completely different from other power generation principles in the past, and has the following characteristics: ① inexhaustible; ② clean, environmentally friendly, low-carbon; ③ not limited by the geographical distribution of resources; ④ can generate electricity nearby; ⑤ converted into electricity The time is short. [0003] There are two main ways to apply solar energy: ① off-grid power generation, ② grid-connected power generation. The off-grid power generation system is to charge the battery with the electric energy generated by the solar cell, and the battery directly...
