This book introduces a modular design approach with complete methodologies to evaluate the performance of stand-alone photovoltaic power system /battery storage. The optimum solar cell area and optimum tilt angle of solar cell are estimated to obtain maximum solar insolation and to avoid unwanted shading , the capacity of battery storage have been determined .The solar cell tracker has been installed by a dc motor with high torque and low speed. The output of its sensor is entered to an amplifier circuit and output of amplifier is entered to comparator to convert the signal to...

Pollution flashover accidents in H.V. insulators had a great assessment in power outage of transmission lines. Two new techniques using artificial neural networks are presented in this book to monitor the discharging level on the insulator surface. The techniques can be programmed to a monitor that produces an alarm signal when the discharging level reaches dangerous range and hence it can be used to predict the flashover accidents before its occurrence.The new techniques using instantaneous leakage current patterns and the meteorological effects are used to classify the discharging activity...
