Wind turbines of the renewable energy station
An independent power station which integrates solar, wind and tidal power went into service on Langan Island near Zhuhai, Guangdong Province.
The Guangzhou Institute of Energy Conversion (GIEC), Chinese Academy of Sciences (CAS) designed and built the station, the first of its kind in the world which combines the three renewable energy.
The station is superior and innovative in terms of system integration, withstanding typhoon and energy utilization efficiency thanks to many patented technologies of GIEC.
The station has a power generation capacity of 105KW (wind power 90kw, tidal power 10kw and solar power 5kw), and a standby diesel generator set with power generation capacity of 100kw.
With an annual energy production of 100, 000 kwh, it could provide enough electricity for about 300 permanent residents on the island round the clock. At the same time, energy is also used to produce fresh water out of sea water. 100, 000 ton of fresh water is produced annually.
The station's operation data showed that wind power alone generates enough electricity for spring, autumn and winter, yet diesel generator set is needed to yield electricity to complement energy supply in summer.
However, the station could meet the electricity demand of the entire island after the tidal and solar power generation settings were set in full performance.
Such a station benefits not only the island's economy but also its environment. Statistics showed it could decrease the consumption of diesel by 42 ton and the emission of carbon dioxide by 130 ton each year.
