1. Distributed generation (DG) located at load center has significant impacts on feeders ' voltage profile. The degree of detail effect is depending on the location and penetration levels of DGs.

2. The short circuit current of large load center that excesses the regulation standard seriously endangers security and stability of power grid.

3. Constant radial load (constant axial load center), in the load, the bearing can withstand 1 million transfer theory, the basic rating life.

4. As the important load center of power system, the establishment and evaluation of distribution system's reliability index has his characteristics.

5. The electrolysis power is the important load center in power system and the hotspot contents of electrical academe internationally.

6. Economies are small footprint, easy to move, in-depth load center, short construction period, reduce waste and so on.

7. Distributed generation (DG) near to load center has several kinds of serious potential impacts on distribution system.

8. The electrical failures of the flame-proof movable load center seriously affect the safety of coal production, while also form a serious threat to personal safety.

9. System structure and operation of power system of the main structure of power supply, power networks and load center.

10. Multiple DC transmission lines were rooted in Shanghai, the load center in Southeastern China, which had injected vitality into the development of the Shanghai Power Grid.

11. Power grid is weak in 3N areas, wind power is far away from load center.

12. High-voltage electrical power transmission line is the artery of electrical-net, and it undertakes the task to transmission electrical power from power station to the load center.

13. This paper focus on the existing security risks and the common electrical failure of the flame-proof movable load center during the operation, and the solutions is analyzed and proposed.

14. The low voltage distribution net orients to the vast low voltage customers that are in great number and disperse in a broadness load center.

15. It is of significance to make online evaluation of power supply ability of urban power network that is regarded as the load center of power network.

16. The proposed solutions have a very important significance to guarantee the flame-proof movable load center to operate safely and steady.

16. try its best to gather and make good sentences.

17. Portland is one of the major ports of entry in the United States for finished automobiles and remains a significant export load center for grain and bulk minerals.

18. It can be reflected not only by the division of container load center and lateral container port but also the construction of network of container transportation.

19. So the Yangtze River Delta region will become a load center with multi-infeed HVDC systems, the large transmission capacity and the intensive landing points of which are very rare in the world.
