In this paper, an analysis of a modular cyclic cascade ICT is presented for nominal and fault operation.
This research analyzes the requirements of suitable SFCL considering the fault operation behaviors of local protective relays and the hybrid DC circuit breakers.
A theoretical analysis of the six-phase motor in αβ and xy current coordinates, for healthy and stator fault operation modes, is also presented.
Furthermore, by utilizing ability of simulating critical situations, this HIL solution can assess the controller in different modes, especially in fault operation.
Furthermore a chosen performance metric of the closed loop system is parameterized the same way as the stability of the system, for further insight into post fault operation.
Results show that it is necessary to take into account the dynamical constraints under fault operation, during the early steps of the system design process.
Starting from a few of these, this paper proposes and analyses several applicative solutions based on the models identification, (mathematical) modeling and supervision of the normal and fault operation in the transportation and distribution networks for (gas and liquid) utilities.
The simulation results are shown in Fig. 4. Simulated sample paths on the three generators' terminal voltage and current waveforms, rotor angles, and angular speed deviations are displayed that contain consecutive durations at normal, fault-on, protection false trip, and post-fault operations.
However, the post-fault operation was affected to some degree.
Since L2 is disconnected from the microgrid, the aggregated load current becomes lower than in the pre-fault operation.
Hence, an improved control system together with circuit level modifications are proposed to improve the CFC post-fault operation and to retain its components from possible damages.
