Ultra-Fast Busbar Protection by Applying TT-transform on Superimposed Current Signals [PDF]
In this paper a new method for busbar protection is presented. In this method high frequency components generated by faults in current signals at the outputs of current transformers of substations are extracted by applying TT transform and then the ...

ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.
