Transferring the driveshaft inertia to the grid via the DC-link in MV drive systems
Catalin Arghir, Pieder Jörg, Silvia Mastellone
This paper investigates a control approach that renders the driveshaft inertia completely available on the grid side and enhances the fault ride-through behavior of medium-voltage…
A Gray-Box Approach for Decentralized Grid-Equivalent Model Identification
Sanjay Chandrasekaran, Florian Dörfler, Florian Dörfler +1
We propose a decentralized, frequency-domain identification algorithm that estimates the grid-equivalent model using local measurements from the perspective of each converter. Sinc…
Resilient AFE Drive Control using Neural Networks with Tracking Guarantees
Nicolas Kirsch, Catalin Arghir, Silvia Mastellone +1
Industrial installations across several sectors have seen a dramatic increase in productivity, accuracy and efficiency over the last decade due to expanded utilization of medium vo…
Reactive power flow optimization in AC drive systems
Sanjay Chandrasekaran, Catalin Arghir, Pieder Joerg +2
This paper explores a limit avoidance approach in the case of input (modulation) and output (current) constraints with the aim of enhancing system availability of AC drives. Drawin…
