Chengdu distributed generation can also make their own lighting

January 27th, the national Power Grid Corp issued on the good work of distributed power grid services, promised to promote the photovoltaic, wind power, natural gas and other distributed power into the national grid. Solar power generation, up to 500 degrees a day yesterday, located in the provincial science and Technology Department of the top floor of the roof of the distributed photovoltaic power generation projects connected to the grid for a security check, supporting facilities have also been tested 6. Next, the project will also install part of the power switch and measurement unit.

Yesterday morning, located in the Sichuan provincial science and Technology Department of distributed photovoltaic power grid project through the State Grid Chengdu power supply company preliminary acceptance. As the first distributed power generation project in Chengdu, is expected to be put into operation in late 9 into the Chengdu public power grid. Solar power generation, up to 500 degrees a day yesterday, located in the provincial science and Technology Department of the top floor of the roof of the distributed photovoltaic power generation projects connected to the grid for a security check, supporting facilities have also been tested 6. Next, the project will also install part of the power switch and measurement unit. The entire project will be formally incorporated into the public grid and formally put into operation in late 9. Provincial Science and Technology Department, responsible person, the project installed capacity of 78 kilowatts, built at the end of the year. According to the pre trial operation, a maximum of 500 degrees a day, about a year can generate electricity of 20 thousand degrees. The main building for the use of the five or six floor of the office building, power generation for a long time for the use of 1 to 4. Weekends and holidays, the power will be incorporated into the national grid sales. 312 pieces of monocrystalline silicon solar power module composed of power generation occupies most of the roof space. Solar power generation array of electric cable, the collector is sent to the indoor inverter. The inverter converts the direct current from the PV power module to 380 volts alternating current, which is connected with the Chengdu public network through the AC cabinet. After the project is put into operation, the excess electricity can be transferred to the public power grid. If the solar array is not enough to generate 78 kilowatts of electricity, the public power grid will automatically enter the system to compensate, so that the power generation system to maintain the rated power for the user to maintain a smooth power transmission.

Photovoltaic power generation projects related to the person in charge of construction, solar photovoltaic technology even in cloudy days can generate electricity, cloudy sun is still emitting radiation, photovoltaic power generation projects can still generate electricity. "The whole system about 25 years.

Return on investment 50 thousand, 8 years after the annual net profit of 6600 yuan. Chengdu power supply company has not yet received a family of distributed photovoltaic power grid project applications. The installation of 5 thousand volts photovoltaic power generation project about $50 thousand. If the installation of the project and put forward the application of the grid, the power company will be free to install access to the public power network lines, switches, protective devices and metering devices and other items.
