The electron correlation effects and Breit interaction as well as QuantumElectro-Dynamics (QED) effects were expected to have important contribution tothe energy level and transition properties of heavy highly charged ions. Theground states [Ne]$3s^{2}3p^{6}3d^{2}$ and first excited states[Ne]3s$^{2}3p^{5}3d^{3}$ of W$^{54+}$ ion have been studied by usingMulti-Configuration Dirac-Fock method with the implementation of Grasp2Kpackage. A restricted active space was employed to investigate the correlationcontribution from different models. The Breit interaction and QED effects weretaken into account in the relativistic configuration interaction calculationwith the converged wavefunction. It is found that the correlation contributionfrom 3s and 3p orbital have important contribution to the energy level,transition wavelength and probability of the ground and the first excited stateof W$^{54+}$ ion.
