"Cleverness" Charged Barbed Wire Net
Current Group, a Germantown-based technology firm, has taken over an ordinary looking house in Bethesda and turned it into a laboratory tor smart-grid technology, the system the company believes will bring the nation’s electricity grids into the digital age.
In the front yard stands a utility pole hooked up to a special transformer that connects the power lines to high-speed Internet. Hundreds of sensors attached to the lines monitor how power flows through the home That information is then sent back to the utility company.
The process lets a utility more efficiently manage the distribution of electricity by allowing two-way communication between consumers and energy suppliers via the broadband network on the power lines. Based on data they receive from hundreds of homes, utilities can monitor usage and adjust output and pricing mresponse to demand. Consumers can be rewarded with reduced rates by cutting back on consumption during peak periods. And computerized substations can talk to each other so overloaded circuits hand off electricity to those that axe not fully loaded, helping to prevent blackouts.
Some utility companies have launched initiatives to give consumers data about their energy consumption habits in an effort to lower energy bills. Smart-grid technology takes such programs further by automating electricity distribution, which would make grids more reliable and efficient.
By partnering with utilities, the company hopes to tap into $4. 5 billion in stimulus grants intended to encourage smart-grid development. When he announced the funding, President Obama pointed to a project in Boulder, Colo. , as an example of a successful smart-grid experiment. Current is one of the companies working on the project.
Current’s chief executive Tom Casey believes the technology will help utility companies better distribute electricity produced by renewable resources, such as solar panels or wind farms. "A smart grid’s system can be paired up with the renewable resources so that when the renewable source is varying, the overall load can be varied as well," Casey told the House Select Committee on Energy Independence and Global Warming. "This will re-dace or eliminate the need for backup coal or gas-based power generation plants. "
What’s the passage mainly about?
选项
A、A new technology is introduced into the nation’s electricity grids.
B、Computers and Internet bring utilities into digital age.
C、The U.S. government will work with a private electricity company.
D、Smart-grid technology will take the place of coal or gas-based power plant.
答案
A
解析
主旨大意题。文章第一段引人了“智能电网”这一概念,第二段是这一一技术如何实现,第三段是数据的处理,第四段讲智能电网的智能之处,第五段讲政府投资,第六段讲智能电网在节约能源方面的作用。由此可知,这篇文章就是在介绍这种新型技术,所以[A]为正确答案。[B]的问题在于选项中的utilities.是电网技术进人数字化时代,而不是供电公共事业部门进入数字化时代,故排除.[C]“政府将与私人公司合作”在文中提到过,但无论从所占篇幅和重要程度来看,都不是文章的主要内容,故排除;第六段最后一句说智能电网技术“这会减少甚至彻底消除对储备用煤或是天然气发电厂的需要,”并不是它会替代发电厂,故排除[D]。
