The field of solar photovoltaic in the world, using the sun have a "V" effect of sunlight directly into electricity. If the inexhaustible power of the grid directly, it would be the benefit of all scientific and technological revolution.
In the past and the smart grid solar PV industry chain in two parallel, power grid has been the industry can not regret. Now, the complete industrial chain in the middle of the two convergence technology has finally made an important breakthrough in Yangzhou. Yesterday, Economic and Technological Development Zone, Yangzhou, glue stick came from the good news: the Electrical Manufacturing Co., Ltd. Jiangsu Powerware two-year success of research and development of photovoltaic inverters and the net, and put into small batch production. Industry believe that the technology breakthroughs, solar photovoltaic industry to fill the application side of the city's vacancy.
As photovoltaic cells and the grid interface unit, and PV inverter is a key component of smart grid connection. State Grid Corporation of smart grid director, Yi-Min Wang, Yangzhou city s economic adviser, said: "Solar electricity generated, to be converted by the inverter, the frequency, waveform and other parameters to keep pace with the grid, parallel to the external network, it will be very easy to damage power devices, glue gun endangering the grid security. "
Some years ago, began to pay attention Powerware electrical inverter technology. The last two years, the company has invested tens of millions yuan, the Ministry of Education jointly Photovoltaic Systems Engineering Research Center and the Southeast University launched technology research. After nearly two years of painstaking research, finally mastered the core of the inverter and network technologies, and has recently successfully completed and the network test. A pleasant surprise is that the company is still based on traditional inverters, digital signal processing (referred to as DSP) and two core components of the transformer was modified, developed a dual-DSP and non-payment transformer new technologies.
"In terms of grid-connected inverter, DSP is equivalent to the human 'brain', the transformer is the 'heart'." Chiang, chairman of Powerware electrical proud to say that double-DSP is equivalent to the inverter mounted on the two a "brain", greatly improving the stability, rather than replace traditional gold transformer silicon steel, so that once the grid conversion efficiency increased to 97.4%, as currently the highest.
Experiment came to an end, the company developed with a new grid-connected inverter Funing exhibitors at the show cause no small stir. Changzhou Trina, Kunshan common silicon, Yangzhou, JA giants such as photovoltaic and Powerware intent signed large orders. In addition, Germany, Australia, India and South Africa, manufacturers are also thrown an olive branch. Among them, the only intention of the contract to a German high as 7,000 yuan.
Chiang told reporters that the company has now developed a different power grid inverter, is proof for some big clients, can be put into mass production this year. The near future, with Yangzhou and national smart grid technologies become more sophisticated, "sitting" in the house power generation will be possible, when the PV inverter will usher in the development of the peak.
