Abstract
Nonlinear simulations based on the reduced set of resistive MHD equations with the transport equation of electron temperature are carried out to investigate the effect of electron temperature perturbation induced by local heating of ECH on a tearing mode activity. Effect of poloidal plasma rotation is also considered in the simulations. It is shown that the local heating can suppress low-m tearing mode instability when O-point of the rotating magnetic island is effectively heated. Large parallel heat conduction causes the radially extending heat deposition profile for small width of magnetic island and magnitude of parallel heat conduction determines the heat power necessary for complete stabilization of the tearing mode.
