Summary: This paper presents a novel encoderless control method based on the stator current vector for permanent magnet assisted synchronous reluctance generators (PMa-SynRG) in renewable energy systems. The rotor position angle and angular speed of the PMa-SynRG are estimated from the stator currents, using only the stator inductance and not the stator resistance. A modified second-order generalized integrator frequency-locked loop (MSOGI-FLL) technique is employed to eliminate current measurement noise and improve phase angle tracking performance. The proposed method achieves rapid and accurate estimation of the rotor position angle and speed, as validated through simulations and real-time hardware-in-the-loop implementation.

Summary: Power systems are experiencing rapid changes in generation mix due to the growth of Inverter-Based Resources (IBRs) like wind and solar PV. This growth poses new challenges for protection engineers, as the output current of IBR facilities under short circuit conditions differs significantly from conventional sources. Local protection schemes for transmission lines may operate reliably for low IBR penetration but face challenges for high penetration. This paper presents a traveling wave-based protection scheme with the aid of Artificial Neural Network (ANN) to overcome these challenges and facilitate widespread deployment of IBRs in transmission systems. Simulation results on a three-bus transmission network with 380Kv voltage level and 94% renewables penetration demonstrate the quick and reliable fault identification, particularly for single line to ground faults, which are the most challenging for the protection system.
