摘要
To maintain the security and stability of power system after failure, it is necessary to locate the fault section quickly and determine the propagation path of the fault impact, a fault section location and fault propagation path reasoning method based on LSTM(Long Short-Term Memory network) is proposed. Firstly, two fault diagnosis models are built by LSTM to realize online fault time judgment and fault section location respectively. Then, the propagation path of the impact caused by the fault can be determined by the ESP(Energy Supply on Port) of the transmission lines near the fault. Finally, the 8-machine 36-bus power grid is taken as an example for verification, and the results show that the proposed model can detect the fault immediately after it occurs, give fault section and fault impact propagation path, and has strong robustness to noise. © 2021, Electric Power Automation Equipment Press.
