"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. "
Why is the system called "smart-grid" technology?
选项
A、Because with all the sensors and transformers, the equipment looks very modern.
B、Because the technology is making good use of computer intelligence.
C、Because with all the data, they can help the utilities make clever decisions.
D、Because the consumers can have wise ideas on the usage of electricity.
答案
B
解析
推理判断题。由题干中的smart-grid technology定位到第四段第二句可知,与以前的技术相比,智能电网在技术上又前进了一步,因为它是通过电脑自动管理电力分布,这可以使整个电网更可靠,也更高效。这说明,通过计算机化的数据传送与分析,进行自动化的管理,是智能电网的“聪明"所在,因此,新技术智能之处在于[B]“很好地利用了电脑的智能”。文章没有提到它外观是否漂亮,因此排除[A];如果仅仅可以让决策者做出明智的决定,就不会用到“智能”二字了,冈此排除[C];而[D]“用户可以做出明智的决定”并不能说明这项新技术非常智能化,故排除。
