Sentence examples for Center of electrical from inspiring English sources

The facade of humanized banners, buttons and icons on our screens masks an unstaffed control center of electrical switches, clicking on and off, their changing patterns of charges translating miraculously but mindlessly into the streaming wonders of words and colors we perceive.

"It is an opportunity to collaborate on a shared system that reduces costs while benefiting a large and important center of electrical demand in the U.S". The research was supported by the Charles H. Leavell Graduate Fellowship, the U.S. Environmental Protection Agency and the Otto Mønsted Foundation.

In control centers of electrical utilities, an important task is the security analysis, even for those companies that already have the modern smart grids.

Therefore, despite that there are many complex and changeable reasons for electrical center migration in actual grid fault, the voltage frequency of migration satisfies the following rules all the time, namely, during the migration of the electrical center, the bus frequency at one side of electrical center circuit branch starts to have similar changes to the other side.

Also it discusses the distribution of extremum, analyzes the voltage frequency characteristics of electrical center and non-electrical center at different voltage amplitude ratios in case of out-of-step of the power grid and further obtains the voltage frequency change rules in the typical scene of electrical center migration.

Firstly, through the establishment and solution to the out-of-step model of the power grid, the analytical expression of the voltage frequency at any position is obtained in the out-of-step oscillation, and the voltage frequency features of electrical center and non-electrical center are analyzed in details.

Figure 3 shows the typical scene of electrical center migration in the multi-machine system, where red dotted line represents the section of the electrical center, G i (i = 1, 2, 3) represent the equivalent machines and a ~ f represent the buses at both sides of each circuit branch.

This criterion is easy to be realized and can adapt to the migration of electrical center.

Open image in new window Fig. 3 Typical scene of electrical center migration.

Then, this paper constructs the typical scene of migration of electrical center to study the change rules of voltage frequency.

Voltage frequencies at two sides of electrical center change oppositely and their curves have no point of intersection.
