Description

technical field [0001] The invention relates to the field of state monitoring of photovoltaic power plants, in particular to a wireless remote data transmission system for photovoltaic power plants. Background technique [0002] With the continuous consumption of global fossil energy, the utilization of new renewable energy has gradually become the focus of attention of all countries. Because of its non-polluting and inexhaustible characteristics, solar energy is the first choice to replace fossil energy. In order to maximize the use of solar energy, in addition to improving the conversion efficiency of photovoltaic materials, it is also necessary to make reasonable adjustments to the operation of photovoltaic power plants, such as timely elimination of faulty equipment. Therefore, it is necessary to be able to monitor photovoltaic power plants in real time. However, since the photovoltaic array is used as a unit in the photovoltaic power station, it is difficult to detect...

AI Technical Summary

Problems solved by technology

However, since the photovoltaic array is used as a unit in the photovoltaic power station, it is difficult to detect all the arrays. If the detection line is laid and the monitoring equipment is installed at each array according to the traditional wired method, the line itself will not only increase the cost, but also consume the power generated by the photovoltaic array. electrical energy

In addition, due to the complex electromagnetic environment of photovoltaic power plants, it is difficult to guarantee the success rate of data communication by using general wireless communication methods.
