【Abstract】 Several important aspects of the on-line dynamic security analyzing (DSA) system are presented, including the construction of the contingency set, retrieval and abstraction of real-time operation state of the power system, selection of the DSA algorithm, and investigation of the open DSA algorithm system. A characteristic contingency set capable of covering all kinds of contingencies and easily defining discretional contingency sequence and fault clearing rules is presented for fast analysis of the system operation mode. At the same time, the construction scheme of on-line DSA system is explained, and some actual system numerical results based on this DSA system are illustrated.更多还原
