Abstract

The NSTX-U Shorted Turn Protection (STP) system is a vital safety feature designed to protect the tokamak's coils during operations. It employs a Kalman filter-based algorithm to monitor coil currents and detect faults in real-time. If an anomaly is detected, the system swiftly terminates the tokamak pulse to prevent damage. Developed with Matlab and Simulink, the STP system has been validated through real-time simulations, ensuring its effectiveness for the upcoming upgrades of the NSTX-U facility. This article presents the theory for implementation of the STP algorithm and the results from simulation and real-time implementation.
