ABSTRACT: A set of reduced MHD equations is derived us-ing the standard energy balance equation. By applying assumption of internal energy, i.e. , a set of reduced magnetohydro-dynamic equations are obtained for large aspect ratio, high tokamaks. These equations in-clude all terms of the same or der as the toroidal effect and only involve three variables, namely the ?ux, stream function and internal energy.
