- Abstract
Cascading tripping accidents are main causes of complex cascading outages in power system. This paper proposes a method of predicting whether cascading tripping will occur according to the nodal injecting power. In order to give the theoretical foundation of this method, this paper verifies that the injecting power of a power network plays a decisive role for the cascading tripping according to the general behavior of cascading tripping and the action of backup relay protector. As to backup relay protector, the type of current and distance are concerned in this paper. On the basis of the theoretical foundation, a method for predicting whether the cascading tripping by using pattern recognition technology is proposed. In this method, the nodal injecting power is taken as input, and whether the cascading tripping will occur is taken as output. By using this method, to a specific initial faulted line, as long as the nodal injection power is given, whether the power network will suffer from cascading tripping accident will be given. In order to prove the rationality and effectiveness of this method, an example in IEEE39 system is illustrated and the result of the example is satisfactory.
