In this paper considered the problem of wrong action of relay protection and automation (RPA) including the distance protection (DP) due to mismatch setting specific conditions of the Power system (PS) operation. The main factorsof this problem: the insufficient and inaccurate information about processes in the equipment and in PS using during RPA tuning; the rough and generalized account of the errors introduced by the RPA hardware and measurement transformers. Based on the research, briefly presented in the article, it is concluded that the adequate mathematical models is useful for analysis the reasons of wrong working DP during solving task of correct setting ones.
