Optimization of design parameters for alternating current stabilizer based on magnetic suspension
Abstract
In the design of magnetic suspension ac stabilizers a set of factors destabilizing left-hand winding dynamics is computed and values established for winding heat-up, duty cycle factor and winding materials densities and resistivities. The objective is to design the magnetic suspension so that disturbances will not put the stabilizer out of order and utilizing the minimum amount of materials. A method was developed showing that the mass of materials and parameter optimization depend upon two dimensionless variables. A nonlinear program created in order to find the variable function minimum and computations on the Elektronika D3-28 computer showed an error not greater than for previous methods. Precision depends upon a uniform magnetic field in the suspension gap and almost not at all on stabilizer geometry. The new method made it possible to construct stabilizers containing 30-40% less mass than previous designs and can be used for other suspension-type equipment.
