Advantageous features of wind and solar complementary
As wind turbines and solar arrays are two kinds of power generation equipment, they can make up for the shortcomings of wind power and photovoltaic independent systems in terms of resources:
(1) Day and night power generation complementary: solar power generation at noon, wind power generation at night;
(2) Complementary power generation in four seasons: strong sunshine in summer and strong wind energy in winter;
(3) High stability: Utilizing the natural complementarity of wind and light greatly improves the stability of the power supply system.
Product Description
Structure of wind and solar complementary power generation system
The wind and solar hybrid power generation system is mainly composed of wind turbine, solar photovoltaic battery pack, controller, battery, inverter, AC and DC loads and other parts. The system is a composite renewable energy power generation system integrating wind energy, solar energy and storage battery and other energy generation technologies and system intelligent control technology.
(1) Wind power generation part is to use wind turbines to convert wind energy into mechanical energy, through the wind generator to convert mechanical energy into electrical energy, and then through the controller to charge the battery, through the inverter to the load power supply;.
(2) The photovoltaic power generation part utilizes the photovoltaic effect of solar panels to convert light energy into electrical energy, and then charges the batteries, and then converts the direct current into alternating current through the inverter to supply power to the loads.
(3) The inverter system turns the DC power in the battery into standard 220v AC power to ensure the normal use of AC power load equipment. At the same time, it also has the function of automatic voltage stabilization, which can improve the power supply quality of the wind and solar hybrid power generation system.
(4) The control part constantly switches and adjusts the working state of the battery pack according to the changes of sunshine intensity, wind power and load: On the one hand, the adjusted power is directly sent to DC or AC loads. On the one hand, the adjusted electric energy is sent directly to the DC or AC load. On the other hand, the excess power is sent to the battery bank for storage. When the power generation can not meet the needs of the load, the controller sends the power of the battery to the load, which ensures the continuity and stability of the whole system.
(5) The battery part consists of multiple batteries, which play two roles of energy regulation and load balancing in the system at the same time. It converts the electrical energy output from the wind power generation system and photovoltaic power generation system into chemical energy and stores it for use when the power supply is insufficient.
The wind and photovoltaic complementary power generation system can operate in the following three modes according to the wind and solar radiation changes:
(1) wind turbines alone supplying power to the load; and
(2) The photovoltaic system alone supplies power to the load; (3) The wind turbine and the photovoltaic system alone supply power to the load.
(3) Wind turbines and photovoltaic power generation system jointly supply power to the load.
Its mode of operation is at night and rainy days without sunshine by the wind power generation system will wind energy conversion output power, or in the solar radiation by the photovoltaic power generation system will solar energy conversion output power, or in both the wind and the sun at the same time both play a role in converting the output of power, through the DC convergence box centralized into the DC power distribution cabinet, by the grid-connected inverter inverter into alternating current to supply the building's own loads, excess or insufficient power through the connection to the grid, the power supply to the loads. The excess or insufficient power is regulated by connecting to the grid to realize the function of all-weather power generation, which is more economical, scientific and practical than using wind turbine and solar energy alone.
Program features
(1) The systems are independent of each other and can be controlled by themselves, avoiding large-scale power outages and providing high security.
(2) Make up for the lack of stability of the power grid, continue to supply power in the event of an accident, and become an important and indispensable supplement to the centralized power supply.
(3) The quality and performance of regional power can be monitored in real time, which is very suitable for supplying power to the residents of rural, pastoral and mountainous areas, developing large, medium and small cities or commercial areas, and greatly reduces the pressure on environmental protection; (4) Transmission and distribution losses can be controlled by the power grid itself, avoiding large-scale power outages and high security.
(4) Low or even no transmission and distribution losses, no need to build distribution stations, reduce or avoid additional transmission and distribution costs, low civil construction and installation costs.
(5) Good peak shifting performance and simple operation; and
(6) Fast start/stop due to fewer systems involved in operation, easy to realize full automation.
