Abstract :
The purpose of this project is to design a voltage transient predictor capable of predicting voltage across the load N time steps into the future. The system is modeled as a generator bus and a load bus connected by a short line model with a switchable capacitor placed along the line. Based on the analytical expression for system states, a novel discrete Kalman filter model is proposed and used for prediction. A study with respect to the capacitor position, switching time, noise level, and number of predicted time steps was conducted
