technical field

The utility model relates to the application field of a wind power complementary power generation system, in particular to a solar photovoltaic power generation device based on a wind power complementary system.

Background technique

Energy is an important material basis for the development of the national economy and people's lives. In the past 200 years, the energy system based on fossil fuels such as coal, oil, and natural gas has greatly promoted the development of human society. However, when humans use fossil fuels, they also bring serious environmental pollution and ecosystem damage. In recent years, countries around the world have gradually realized the importance of energy to human beings, and even more aware of the damage to the environment and ecosystems in the process of conventional energy utilization. Countries have begun to control and alleviate the deteriorating environment according to their national conditions, and regard the development and utilization of renewable and pollution-free new energy as an important content of sustainable development.

Wind-solar hybrid is a set of power generation application system. This system uses solar cell arrays and wind generators (to convert alternating current into direct current) to store the generated electric energy in the battery pack. When the user needs electricity, the inverter will The DC power stored in the storage battery pack is converted into AC power and sent to the user's load through the transmission line. It is a new type of energy generation system with high cost performance, which is a new type of energy generation system with high cost performance, and has a good application prospect.

Because of the lack of detailed mathematical calculation models, and the system is only used for users with low guarantee rates, the service life is not long; the solar photovoltaic power generation system uses The photovoltaic effect of solar cell semiconductor materials is a new type of power generation system that directly converts solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems require batteries as energy storage devices. They are mainly used in remote areas without grids and areas with scattered populations.
