Current sensor failures

Procedures for diagnosing bearing failures of induction motors based on motor current signals in published methods commonly denoise signals acquired from current sensors, then extract the typical characteristics from the denoised signals, and use a classifier to discriminate the state of bearing.

Currently, in Vietnam, the management and operation of the power system face challenges and difficulties due to complex terrain conditions, natural disasters, floods, and typhoons. In addition to the power grid failures caused by natural disasters that damage the power system. The power grid failures caused by humans are serious and directly affect human life.

In this paper, an enhanced active fault-tolerant control (FTC) is proposed to solve a current sensor failure in the induction motor drive (IMD) using two current sensors. The proposed FTC method applies only one observer to diagnose the faults and recon gure the control signals by the space stator current. The diagnosis function is made up of a comparison algorithm between the measured current space vector and the estimated space vector
