Release time :2016-11-21 08:57:47

2 the design elements of the system (1) make full use of wind energy, solar energy and renewable energy, to ensure uninterrupted power supply.

(working conditions: 2 suitable environmental temperature -15~45C 95% relative humidity and rain; coastal salt spray; wind speed 330m/S; instantaneous maximum wind speed 40m/S 150kca/cm2; total solar radiation; sunshine 3000h. (3): stability guarantee smooth operation, safe and reliable, can be used in all-weather unattended conditions.

(4 no electromagnetic interference: wind power generator and its charging controller will not have harmful electromagnetic effects on the surrounding environment.

5 product quality assurance: wind turbine design, manufacturing, product quality implementation of national and industry standards, product quality assurance system in line with the provisions of the subject.

Card specification, 1EC1215 crystal silicon surface by photovoltaic module design quality certification and test, the national standard GB/T1400792 land total solar module specification, GB/T14009 solar cell module parameter measurement method 6 (7 batteries in line with the provisions of the national standard GB13337.191 fixed type lead-acid battery and the detection mechanism has achieved GB/T15481 certification test.

The total power of the system is P=60W/85%=71W, which is the efficiency of the inverter and power supply lines.

Wind power generator with rated power of P, solar battery components in rated power P2, battery capacity is C. according to the natural conditions of street lamps installed location: the maximum continuous time wind power generator and the solar battery components at the same time not power is 3D; the maximum continuous time of the solar battery component can not be power is 12D; the maximum continuous time wind power generator not for the 6D. power battery 3 side determination for 24 hours a day; according to the actual specification of battery and battery to reduce the amount of raw shellfish I, from C=340Ah, the actual configuration for the C=2V/ 340Ah battery 12 x1 group.

4 wind turbine power generation solar battery cannot be identified in the weather, usually for rainy days, the wind speed and duration are much higher than the annual average wind speed and time, according to the meteorological data and the site of the natural environment, in the period of 4 wind turbine according to the specifications and reliability of the installation and use MPSQW., the actual configuration is: 1 WV-02-350W wind generator.

EV-02 series wind generator mechanical automatic clutch system, get rid of the traditional wind turbine start demanding bound wind, the wind is very small under the condition can be obtained when the wind turbine speed and inertia of the fan blade, automatic start driven generator clutch system, greatly improving the efficiency of power generation of wind power generator the wind power generator, increase working time. EV-02 series wind generator with an autonomous yaw system, in the case of wind is not the case can take the initiative to the wind in the wind, to get the maximum wind area, improve the efficiency of wind turbine.

5 solar power generators can be determined in wind power generation is usually sunny weather, continuous, and daily sunshine hours is much higher than the average annual sunshine hours, according to the meteorological data and the site of the natural environment, take the 6h/A. conveniently according to appearance, specifications and installation of the solar cell P2=200W, the actual configuration: 100Wx2 block.

6 equipment selection, as shown in table 1.

Table 1 the number of equipment selection equipment name specification unit of wind turbine controller Taiwan scenery complementary lamp pole root solar cell battery solar battery bracket set 7 lamppost design scheme of wind generator and solar cell module is a landmark combination of scenery complementary street, to ensure that the wind power generator and solar cell module can smooth and safe operation. At the same time with a variety of shapes lamp, lamp design should be complementary to the free-standing pole. The top wind generator is located in the central pole, the solar cell component is located in the pole.

The strength design should be consistent with the city road lighting engineering specifications, construction and acceptance of small wind turbine technology conditions on the pole, a wind generator tower tube, and the natural frequency and the wind power generator is big, can resist 12 typhoons. Pole height should be according to the installation site to determine the geographical environment, to ensure the use of wind turbines are not affected. The solar cell assembly is generally not with wind turbine blades Xiangqian involved shall prevail, at the same time to ensure that solar modules are not post occlusion. The installation height of the lamp is determined according to the design requirements.

8 end of wind energy and solar energy is inexhaustible and pollution-free and inexhaustible renewable energy, small wind power and solar photovoltaic system obtained the preliminary application in our country. Perfect combination of wind power generation and solar photovoltaic power generation, to lay the foundation for the scale, industrialization and marketization of the two kinds of new energy sources. Early small and medium sized wind turbines are used in remote areas, natural conditions are good, low cost, shape does not require beautiful, technical requirements are not high. Transferred to the economically developed areas, the natural conditions are relatively poor, low industrialization, high technical requirements, the cost is relatively high, beautiful appearance requirements. With the difference and demand difference of regional environment greatly, increase of wind and solar power generation technology requirements, process such as low speed, low voltage energy storage, anti typhoon, salt fog corrosion, intelligent control and a series of technology constantly put on the development of the. In the country's strong support and scenery complementary lamp system technology is being perfected, the future people will be on the street, the road will see.
