Based on the Shafranov current moment theory, reconstruction of the plasma boundary in HL-2A is studied by using the movable current filament (VCF) method. Compared with the fixed current filament (FCF) method and the finite current element (FCE) method that we've used before, this method has the advantage of accurately rebuilding the fast evolving plasma boundary by using only 1—3 filaments, which offsets the drawbacks of the FCF and the FCE methods. Combining the movable current filament method with the FCF or the FCE method, the plasma boundary can be displayed in real time and the plasma shape can be controlled during the whole discharge process.
