Abstract: The sliding mode AGC controller and method includes Genetic Algorithms (GA) to find the optimal feedback gains and switching vector values of the controller. In order to provide enhancement of the system dynamical performance and a reduction in the SMC chattering, two objective functions are provided in the optimization process. The tested two-area interconnected AGC model incorporates nonlinearities in terms of Generation Rate Constraint (GRC) and a limiter on the integral control value. Comparison with previous AGC methods reported in the literature validates the significance of the sliding mode AGC controller.

Abstract: Contamination monitoring of high voltage insulators provides a system and method producing an early predictor for high voltage insulator failure, allowing repairmen to either already be on site when a high voltage insulator fails in order to expedite repair time, or allowing repair and/or replacement of a faulty insulator before the failure actually occurs. The system and method provide transmission of an alarm signal when contaminant levels (such as equivalent salt deposit density (ESDD) levels) formed on a high voltage insulator exceed pre-selected threshold values, indicating the likelihood of high voltage insulator failure.
