Description
Technical Field
The present invention relates to the field of power supply technologies, and in particular, to a power supply device and a power supply method.
Background
Wind is the most familiar natural phenomenon in humans, and is ubiquitous. The solar radiation causes uneven heating of the atmosphere on the earth surface, which causes uneven distribution of atmospheric pressure. Under the action of uneven pressure, air moves along the horizontal direction to form wind. Wind energy is the most active renewable energy source, and it is essentially a conversion form of solar energy, and is therefore inexhaustible. Wind direction and wind speed in wind energy are complex in space-time distribution, for example, in monsoon and sea-land wind formed by influence of sea-land difference on airflow movement, valley wind and mountain wind caused by thermal reasons in mountainous areas, the utilization efficiency of the wind energy is low due to the randomness of the wind force and the wide variation of the wind speed, and a lot of technical difficulties still exist in the practical utilization of the wind energy. Nevertheless, the wind energy resource has the following advantages:
(1) wind power generation is a renewable clean energy source: wind power generation is a renewable clean energy, does not consume resources, does not pollute the environment, and is an incomparable advantage compared with other conventional energy sources (coal power and oil power).
(2) On-site availability, no transportation required: the uneven geographical distribution and the uneven industrial layout of the fossil energy coal and the petroleum cause the uneven transportation of the coal and the petroleum. The energy must be mined and transported to a destination over a long distance, which puts pressure on transportation. Even if power can be supplied by a power grid, the power grid can be used conveniently in places where power grids are not easy to reach, such as mountains, islands, grasslands, plateaus and the like, and clean energy is fully utilized.
(3) The construction period is short: the construction period of the wind power plant is short, only a few weeks are needed for installing a single wind power generating set, and the construction period of the wind power plant of ten thousand kilowatts is only half a year to one year from civil construction and installation to production.
(4) The operation and maintenance are simple: the wind power generation automation level is very high, the wind power generation automation level can be completely unattended, only necessary maintenance is needed to be carried out regularly, and the problem of thermal power generation overhaul does not exist.
(5) The economy is high: the economy of wind power generation is improved day by day, the problems of building plants, building dams, flooding land, moving residents and the like do not exist, the wind power generators are installed dispersedly, and the occupied area is small. The method has the advantages of no consumption of fuel, no three-waste treatment problem, low cost close to thermal power and lower cost than oil power, nuclear power and photovoltaic power generation, and has strong competitiveness from the viewpoint of comprehensive economic benefit.
(6) The reliability is high: the technology of wind power generation is the most mature in new energy power generation. Is a safe and reliable energy source.
The devices required for wind power generation are called wind generating sets. The wind generating set can be divided into three parts of a wind wheel, a generator and a tower. The wind wheel is an important part for converting the kinetic energy of wind into mechanical energy and consists of two or more propeller-shaped impellers. When wind blows to the blades, aerodynamic force is generated on the blades to drive the wind wheel to rotate. The blade is made of materials with high strength and light weight, and is currently manufactured by glass fiber reinforced plastics or other composite materials. There are also vertical wind wheels, s-shaped rotating blades, etc., which also function as conventional propeller-type blades. The existing wind power generation device has low power generation efficiency, and the power supply method is relatively complex and needs to be further improved.
