Abstract Details

2019, Master of Sciences, Case Western Reserve University, EECS - System and Control Engineering.
This thesis describes the design and implementation of a finite state machine representation of a voltage regulation control system for a load tap-changing transformer. It also introduces a method for observing physical operating conditions based on sequences of state transitions within the control system. Simulation of a daily load pattern applied to a distribution network yields the probabilities of specific sequences occurring, which can be used to detect irregular behavior. State transition data correlated with an expected load pattern can be used to verify whether behavior is consistent with the sensor data observed by a system operator. Possible adverse scenarios include when either the operator or the control system is receiving falsified measurements, as would occur during a replay attack. The effectiveness of this technique is quantified by how quickly it can detect voltage anomalies as they occur.
