Query: Deep-learning Based Modeling of Fault Detachment Stability for Power
  Grid   The project intends to model the stability of power system with a deep
learning algorithm to the problem, aiming to delay the removal of the fault.
The so-called "fail-delay cut-off" refers to the occurrence of N-1 backup
protection action on the backbone network of the system, resulting in longer
time for the removal of the fault. In practice, through the analysis and
calculation of a large number of online data, we have found that the N-1
failure system of the main protection action will not be unstable, which is
also a guarantee of the operation mode arrangement. In the case of the N-1
backup protection action, there is an approximately 2.5% probability that the
system will be destabilized. Therefore, research is needed to improve the
operating arrangement.
