This paper presents comparative performances of an linear and disk AC MHD power generation with an active power. The configuration of linear and disk consist of the top and bottom stators. the top stator bottom stator winding are connected with a power supply and an electrical load, respectively. The interaction between the metal fluid and traveling magnetic field can be explained by Maxwell’s equations and Ohm’s law based on the method of finite-elements. Power flow and electrical efficiency of an AC MHD power generation have been evaluated by various slip conditions. The optimal operating point of the generator was defined by adjusting slip values. The result confirms that disk AC MHD power generation has high active power more than linear AC MHD power generation at the same slip.

Superconducting Outsert

The power supply scheme for the superconducting outsert of Steady High Magnetic Field Facility (SHMFF) in High Magnetic Field Laboratory of Chinese Academy of Sciences is a switching power supply with active DC power filter. In this paper, a novel shunt liner active power filter (SLAPF) is designed to overcome the disadvantages of existing dc active filter schemes. The system structure and working principle are presented at first. Then the design flow is described, which includes the control method of the current compensator, the analysis of topology chosen for auxiliary power supply, At last, the experimental results show that the filtering effect of SLAPF is good enough to make the power supply meet the technical requirements.

Load Profile

A load profile measuring device takes information about the power consumption without modification of the power lines. Using current transformers, the current is measured in each of the phases and the active power consumed by the user is determined. The developed software for it allows for simultaneous recording at different user selectable timing intervals. The device is designed and tested in two facilities - a School and a Farm.
