This paper summarizes the characteristics of the electricity load data collected every 15 minutes of power users. The single-day load data of single power user is taken as a 96-length vector, and the single-day data of n users is taken as a 96-column set. Single-user monthly data and annual data are described as a 30 (31) × 96 matrix and a 365 (366) × 96 matrix respectively. By comparing the wavelet...
Contact acoustic nonlinearity (CAN) between rough interfaces in solids are mainly caused by nonlinear stress-strain relationship between contact interfaces. According to classical Hertz theory, unidirectional normal contact stress between two rough interfaces was built as functions of interface parameters on roughness. Nonlinear spring stiffness was further deduced from such functions. Then two rectangular...
As the oil and gas discovery and processing is moving towards the remote deepwater areas, the electric power delivery via long step-out to the multiple subsea processing equipment becomes more crucial. The direct current (DC) power transmission and distribution system using modular approach is considered as a competitive system architecture for subsea power delivery. This paper presents a selective...
