Abstract

Owing to the rapid development of the scale of power grids and increase in the object number of generator trippings implemented by the power stability control system in fault emergency situations

the traditional optimal generator tripping scheme based on the exhaustive method can no longer meet the requirements of fast tripping in the large-scale power grid stability control system. In order to improve the computational efficiency of the optimal combination of generator trippings

an optimal generator tripping scheme is put forward based on the implicit enumeration method. According to the characteristics of the optimal problem of generator tripping

a pruning strategy is formulated to increase the computational efficiency by effectively reducing the calculation number of generator combinations during the enumeration process. It is shown by simulation results of an example that the optimal generator tripping scheme based on the implicit enumeration method can reduce about 70% of the optimal computation time

realizing fast generator tripping by the power stability control system.
