Description
Technical field
The utility model belongs to electrical equipment technical field, relates to a kind of electricity generation system, especially a kind of island intelligent power generation system based on multiple new forms of energy.
Background technology
At present, the electricity consumption present situation on Chinese island is: China is the vast country in a coastal areas and territorial seas, and the island that national area is greater than 500 square metres have more than 6000, and wherein the island of about 94% are unoccupied island; Area is at 500m
2following island and about up to ten thousand of cay; The island gross area about 80,000 km
2, account for national total area 0.8%, island shores reaches 1.4 ten thousand km.The island of 80% are distributed in southeastern coast---Zhejiang, Fujian, the wide Three Eastern Provinces, and it is coastal that 10% island are distributed in northeast---and Shandong, Liaoning Er Sheng, also have 10% island to be distributed in Hainan, Taiwan, Guangxi San Sheng.
(1) diesel generating set generating
The distance in these island of southeastern coast and continent, generally at 10 ~ 50 nautical miles, is steamer with the traffic in continent, and because island water resource is poor, Coal Transport difficulty, therefore these island normally adopt diesel generating set to generate electricity.
According to the relevant island investigation of Zhejiang, Fujian two province, the electricity price of in January, 1999 ~ 2002 diesel generation in year June is 3 ~ 4.5 yuan/kWh, and due to power benefit not good, power-on time is also only generally point at 6 in evening to night 11, in table 1.
Table 1 Zhejiang, part island, Fujian power information
| Newfoundland | Permanent resident population | Diesel generation electricity price/unit (kWh) -1 |
| Zhejiang Tan Hu Shan Dao | 889 | 3.5 |
| Nanji Island, Zhejiang Province | 2913 | 3.0 |
| Miao Zihu island, Zhejiang | 3000 | 3.0 |
| Zhejiang Bei Guandao | 413 | 3.5 |
| Xi Lvhua island, Zhejiang | 2228 | 3.5 |
| Flora of Dayang Mountain in Zhejiang Province island | 8972 | 3.0 |
| Zhejiang Dong Fushandao | 1184 | 3.5 |
| Great Yu Shan island, Zhejiang | 3215 | 3.5 |
| Bei Shuan island, Fujian | 1800 | 4.5 |
| Fu Ying island, Fujian | 1400 | 4.5 |
As can be seen from Table 1, seriously restrict the economic development on these island without electricity and electricity price height, the living standard of resident also cannot improve.
(2) island power cable transmission of electricity
Sea electric power cable is mainly used in underwater transmission high-power power, is equal to the effect of underground power cable, and the occasion only applied is different with the mode of laying.
Submarine cable engineering is known as the heavy construction of complicated difficulty by countries in the world, from environment detection, marine physics investigation, and the design of cable, manufacture and installation, all apply complex technology, thus the manufacturing firm of submarine cable is few in number in the world, mainly contain Norway, Denmark, Japan, Canada, American and Britain, method, Yi Deng state, these countries also provide laying technology except manufacture.
The sea electric power cable of current China application still needs import.Submarine cable circuit is long, expensive, be that island power also is more difficult realization in China by sea electric power cable.
High electricity price makes the living cost of the numerous fishermen masses on island far away higher than continent, and the people's livelihood not only seriously restricting the island masses is improved, but also constrains the further development & construction on island and the development of marine economy.
At present, the development speed of new forms of energy is very fast, and the development of relevant new forms of energy is as follows:

Tide be a kind of reserves very big, inexhaustible, nexhaustible, do not need exploitation and transport, clean free of contamination regenerative resource.Build tidal power station, do not need immigrant, do not flood soil, there is no problem of environmental pollution.But tidal power also exists shortcoming, tidal range and head often changed in one day, and when without special regulation measure, intermittence of having exerted oneself, makes troubles to user.There is half monthly variation in tide, tidal range can differ two times, therefore firm output powcr, installation annual utilization hours are also low.
(4) wave-energy power generation
Wave energy has that energy density is high, distribute the advantage such as wide.It is a kind of inexhaustible renewable and clean energy resource.Especially in the winter that energy resource consumption is larger, utilizable wave energy energy is also maximum.Low power wave-energy power generation, to put it over application at navigation buoy, beacon etc.
There are wide marine resources in China, and the theoretical memory space of wave energy is about 7,000 ten thousand kilowatts, and coastal wave energy energy-flux density is approximately every meter 2 kilowatts ~ 7 kilowatts.In the place that energy-flux density is high, outside every 1 meter of coastline, flowing of wave is just enough to for 20 families provide illumination.
(5) energy by ocean current generating
Energy by ocean current refers to the kinetic energy of marine stream, the regular marine stream mainly referring to marine stream comparatively stable in seabed water channel and straits and cause due to tide.The energy of energy by ocean current is directly proportional to the quadratic sum flow of flow velocity.Current power generation relies on the impulsive force of ocean current that the hydraulic turbine is rotated, and be transformed into the mechanical energy of high speed rotating, drive electrical generators generates electricity.
Thus, can finding out, when utilizing existing electricity generation system can not meet the use of people completely, can suit measures to local conditions to develop a kind of electricity generation system based on above-mentioned multiple new forms of energy.
