Description

Technical Field

[0001] The utility model relates to the field of photovoltaic controller testing, in particular to a photovoltaic tracking bracket simulation device. Background Art

[0002] With the economic development of the country and the high-quality and large-scale development of society, the demand for photovoltaic power generation is growing day by day, and people are gradually paying attention to the efficiency of photovoltaic power generation. Under such social needs, the demand for photovoltaic tracking brackets is also becoming more and more important. It is a necessary condition to make a good photovoltaic tracking bracket controller. The research and development and production of tracking bracket controllers require additional equipment such as rotary reducers, single-axis inclination sensors, and high-power power supplies to meet the testing conditions; such equipment requirements bring higher threshold requirements for the research and development of controllers and the algorithm debugging of tracking bracket controllers.

[0003] The single-axis inclination sensor itself has a certain cost, and it needs to be installed on the motor gearbox mechanism, so it also takes up a lot of time cost; a high-power power supply must be equipped due to power requirements, which also increases the equipment cost, use cost and time cost; the slewing reducer has a certain operating risk, large footprint, high noise pollution, and time consumption due to its high cost, heavy weight, high power requirements and low operating speed; and the slewing reducer has hardware limits, so when the slewing reducer runs to the limit, it may cause excessive current and burn the equipment. In severe cases, it may even damage the equipment and cause irreparable losses; at the same time, the slewing reducer cannot quickly change the angle position of the gearbox. Each time the angle test is changed, a lot of time is required to wait.

[0004] Therefore, how to reduce the demand for testing equipment in the research, development and production of photovoltaic controllers and provide a more efficient and convenient way for photovoltaic controller production testing has become an urgent problem to be solved by technical personnel in this field.
