  We developed an original model describing the process of the frequency comb
generation in the self-injection locking regime and performed numerical
simulation of this process.Generation of the dissipative Kerr solitons in the
self-injection locking regime at anomalous group velocity dispersion was
studied numerically. Different regimes of the soliton excitation depending on
the locking phase, backscattering parameter and pump power were identified. It
was also proposed and confirmed numerically that self-injection locking may
provide an easy way for the generation of the frequency combs at normal group
velocity dispersion. Generation of platicons was demonstrated and studied in
detail. The parameter range providing platicon excitation was found.
