The invention relates to the field of a local small electric grid networking engineering and design, in particular to a weak tie receiving end small electric grid tie line high resistance compensation method. The method includes the following steps: a systematic electromagnetic transient simulation model is built, the charging reactive power total quantity Qc and the high resistance compensation quantity Qh1 of a tie line are confirmed, the capacity Qh12 of parallel high resistance of a small electric grid side of a tie line receiving end is confirmed, the capacity Qh11 of parallel high resistance of a main grid side of the tie line is confirmed, and according to the capacity Qh11 of the parallel high resistance of the main grid side of the tie line and the capacity of Qh12 of the parallel high resistance of the small electric grid side of the tie line receiving end, high resistance of the weak tie receiving end small electric grid tie line is arranged. Requirements of local electric grid self-excitation prevention and control and power frequency excess voltage suppression are synthetically considered, meanwhile, consideration is given to the character of system steady state voltage regulating so that power flow and voltage of the kind of an electric grid are distributed more reasonably.
