Abstract: The partial discharge noise separation method uses Independent Component Analysis (ICA) for de-noising partial discharge (PD) test signals having a noise signal component and a partial discharge component. Assuming that the noise signal component and the PD signal component are both statistically independent of each other and non-Gaussian, the ICA algorithm separates the noise component from the PD signal component from two partial discharge test signals acquired from two separate couplers per phase that are connected to the windings of a three-phase rotating machine.

Abstract: The method for estimating corona power loss in a dust-loaded electrostatic precipitator numerically solves Poisson's equation and current continuity equations in which the finite element method (FEM) and a modified method of characteristics (MMC) are used. The system is a computerized system that produces results showing how different parameters such as discharging wire radius, wire-to-wire spacing, wire-to-plate spacing, fly ash flow speed and applied voltage polarity influence corona power loss and current density profiles.

Abstract: The particle swarm optimizing sliding mode controller is applied to an interconnected Automatic Generation Control (AGC) model. The system formulates the SMC design as an optimization problem and utilizes a Particle Swarm Optimization (PSO) algorithm to find the optimal feedback gains and switching vector values of the controller. Two performance functions are used in the optimization process to demonstrate the system dynamical performance and SMC chattering reduction. The tested two-area interconnected AGC model incorporates nonlinearities in terms of Generation Rate Constraint (GRC) and a limiter on the integral control value.
