| Abstract: | With the expansion of the power grid, to solve the short-circuit current exceeding limit has become a key problem, which troubles the security and stability of power grid. The same issue is also existed in Henan power grid. To solve it, the 2011-year short-circuit current level is researched, and the limiting measures are proposed based on a great deal of calculation. When the transformers of UHV Nanyang Station operates, its influence on the short-circuit current is analysed. In the end, some methods are suggested to limit Henan power grid short-circuit current. |
