A new one-dimensional approach to the lower hybrid current drive (LHCD) modelling in the presence of an inductive electric field is suggested in this paper. The approach is based on using time-dependent solutions of a well-known Fokker-Planck equation for the distribution function of fast electrons calculated concurrently with solving plasma transport equation in the Automated System for TRansport Analysis (ASTRA) . A good agreement between experimental and modelling results is demonstrated for an FT-2  plasma shot. Also new formulae for the steady-state solution of this kinetic equation are found.
