Experimental analyses are used to investigate the impact of low order harmonics on the operation and tripping times of overcurrent relays. Two analytical approaches based on relay characteristics provided by the manufacturer and simulations using PSCAD software package are used to estimate tripping times under non-sinusoidal operating conditions. Experiments were conducted such that the order, magnitude...
Ni-Cd batteries are nonlinear electrochemical devices with different characteristics at different charge currents. This paper proposes a neural network based method for simulation and modeling of Ni-Cd batteries that considers the impact of charge current. Simulations and measurements are performed for the RBF neural network and advantages and limitations of the model are presented. Inputs of the...
