System designFor scenery complementary power generation system design, there are many problems involved. Here mainly through a list, briefly describes the core problem of the power distribution of the wind turbine and solar cell.
In the case, the wind turbines use Taiyuan Western Machinery Factory 50W-200W series products, solar cells use Harbin Clan 3W-120W amorphous silicon series, and its battery conversion efficiency is 6%, life expectancy for 20 years. The battery is selected from the battery, the life is 3-5 years, and the discharge rate is 30%. Not equipped with a diesel generator.
Huizhong - Huizhong brand OPZV tube colloidal battery main components: Polar material 1 # Electrolysis lead, separator is an imported partition for the United States, colloid is German import colloid.
In July this year, the "Central Enterprise Corporate Reform Work Implementation Plan" clearly requires that central enterprises supervised by the State-owned Assets Supervision and Capita of the State Administration of State will complete the company's restructuring. As of the end of July, there are still 69 group companies in 101 central companies, one of the Three Gorges Groups. On September 27, 1993, in order to build a Three Gorges Project, the development of the Yangtze River is officially established by the State Council, China Changjiang Three Gorges Project Development Corporation is formally established. On September 27, 2009, it is changed to China's Yangtze River Three Gorges Group Company. It has become a world * big One of the clean energy groups of hydropower development enterprises and China *.
According to the data, the local wind turbine and the annual power generation of the solar cell are measured, as shown in the following table:
Data (unit kWh / year)
2. Depending on the load requirements, select the possible power generation mode, set the load power 130 watts, working for 5 hours a day, 120KWH annually. According to the above table, you can choose a 100 WyC wind generator alone, or two groups of HC915'1220 panels in parallel 100W solar cells, or 50 WYC wind turbines plus a group of HC915'1220 50W solar cell complementary power generation.
3. The battery capacity is determined, and if there is no need to supply power, such as the electricity electricity, in order to reduce the cost, it is possible to consider the weather change based on the energy and occasion of the daily load, such as a differential station, the navigation light, must consider weather changes ( Such as a rainy day, continuous windless) factors plus amendments. Set battery voltage 24V, calculation results
