【Abstract】 With the continuous enlargement of network’ s scale and reinforcing of networks structure, the problem of the short-circuit capacity has become more and more serious in the operation of the large-scale power grid, in which the safety and stability of operation are being affected much seriously. Several measures to control the level of short-circuit current are presented by calculating and analyzing of power grid’s structure in Beijing power network. These measures are of instructional significance in the planning and operation of the large-scale power grid.更多还原
