May 4 news in recent days, China's State Grid Corporation of Science and Technology project "access to the city power grid for 100 kilowatts of solar photovoltaic roof-level and network test platform for power stations and implementation of research" through acceptance, marking China's first high-level structure of the existing framework building construction on the success of large-scale photovoltaic systems engineering, to promote large-scale development and utilization of solar energy and photovoltaic power generation projects and provides an important network to run technical support.
In order to effectively promote energy-saving emission reduction, China's State Grid Corporation of active solar energy and other new projects and research network. China's national power grid in the distributed power generation and grid, such as a series of theoretical studies based on the end of last year in Zhejiang province-owned power companies in production scheduling, respectively, the construction of the roof of the building a single-phase 220-volt 5 kilowatts of photovoltaic power station grid test , a 250 kilowatts of photovoltaic and 10 kV high-voltage power station and a network model 60 kilowatts of photovoltaic grid-connected three-phase 400-volt power stations, and developed a multi-grid PV system test platform for grid-connected PV system safety performance, operating efficiency, such as detailed and thorough study of the test, in view of the characteristics of solar power generation has developed a safe and stable operation of power grids to ensure that the photovoltaic system and network specifications. Three power stations in the January 2 this year and the network put into operation formally, as of April 28, has 807 hours power generation, power generation 55,200 kwh, 3.1 tons of carbon dioxide emissions reduction, good running, the system stability. With the use of integrated photovoltaic glass curtain wall construction is different from the large-scale photovoltaic power plant system and physical separation of buildings, marketing a wide range of applications. According to estimates, the system generating capacity is expected in about 30 million kilowatt hours and annual emission reduction of about 170,000 tons of carbon dioxide, nitrogen oxide emission reduction of about 220,000 tons, resulting in nearly 1.2 million yuan tariff income.
