The Mengxi-Tianjingnan 1000kV UHV project will put into operation in 2016; the power grid of Beijing will be injected and consumed the UHV. But the three-phase short-circuit current of 500kV Shun Yi station may exceed its breaking capacity, and also the operating characteristics of the peripheral placement of UHV grid will change significantly. In order to better respond to the effect of UHV power grid bring access to Beijing, the two-port power equivalent theoretical analysis is used in this paper, and next the BPA power system analysis software is used to simulate and verify the Beijing power grid. And then the reasons of excessive short-circuited and interaction effects of all voltage levels of short circuit current are analyzed. The different current limited measurements are analyzed and compared. At last, the current limitation measures of Beijing power grid are put forward, which provide the technical support for the grid operation. |
