corresponded to 40% of the total load demand of Jeju Island. The HVDC system basically adopts inverter operation at Jeju in which current control is used as the main control and average gamma control is used as the secondary control. At Haenam‚ where rectifier operation is adopted‚ voltage control is used as the main control and current control is used as the secondary control. Fig. 1 presents the control scheme of the HVDC system[1]. Faults in the Cheju-Haenam HVDC System could be caused by the disturbances

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

and philanthropist. His work is well recognized internationally as well. This memo responds to your request on the progress of my research project for “Testing of Battery System”. As you might remember my research was on the simulink model of the rectifier and inverter for testing the batteries. This memo will first present the research that I have completed so far‚ including preliminary results. Then this memo will discuss the remaining research and suggest modifications to that research based on
