摘要

In this paper, a general algorithm for automating cyclic security analysis is presented. It is shown that the effect of the outage on the power flows and the bus voltages of an arbitrary line can be estimated by a series of filter values which make use of data obtained from previous security analysis and filters out non-dangerous contingencies, with reduced computation time. Tests have been performed on the French 225-400 kV grid containing 462 nodes and 855 branches, with the real states for three relevant days, with light and heavy load level. For each day, 96 real states corresponding to a 24 h period in 15 min steps were analysed. The tests confirm that our approach is both applicable and accurate.
