A coupled electromechanical and hydrodynamic simulation of a novel generator connected to a heaving buoy for wave energy conversion has been developed. The simulation is based primarily in MATLAB using its built-in Ordinary Differential Equation (ODE) solvers. These solvers have acted on the data derived from an electromagnetic finite element analysis and from the WAMIT wave interaction simulation...
This study describes dynamic characteristics of a linear electromagnetic actuator for Electric Vehicle Relay(EV-Relay). Axi-symmetric finite element analysis was performed to obtain electromagnetic properties of the actuator. A displacement-force relationship was also calculated under condition of applying constant magnetomotive force(mmf) and its validity was confirmed by experimental result. A 3-dimensional...
With the recent increase in social demand for 'Power IT', a dire need for electrical equipment capable of remote control, such as measuring, communication, etc., has arisen. Therefore, this paper shows that molded case circuit breaker (MCCB), which is a typical electrical equipment widely used in low-voltage circuits, can be miniaturized and remotely controlled by adapting electromagnetic force driving...
The paper presents three-dimensional magnetic field analysis of recently developed electromagnetic valve actuator. Permanent magnet is employed in the actuator construction in order to reduce the energy consumption. Finite element method using magnetic vector potential formulation with edge elements is employed. Results are obtained for the magnetic field distribution and the static force of the actuator...
Recent years have witnessed that the Korean government prompts the dasiaPower ITpsila enterprise to combine electric power industry with information technology (IT). Especially, in a move to shore up the distribution automation system, the necessity for remote control of molded case circuit breaker (MCCB) becomes more important. In this paper, we aimed to propose a remotely controllable MCCB, of which...
