The invention belongs to grouping methods for pressurized-water-reactor nuclear power station control-rod position coils, and concretely relates to a grouping method for pressurized-water-reactor nuclear power station control-rod position detector coils. The grouping method comprises the following steps: dividing 16 coils of an A group according to the odd and even sequence into an A1 subgroup and an A2 subgroup and enable each subgroup to have 8 coils; then performing positive wiring and negative wiring on the coils of each subgroup according to the odd and even sequence; designing an independent rod-position measure channel of each subgroup, processing an induction voltage signal of the subgroup and generating a rod-position measure signal of the subgroup; and then combining processed signals A1 subgroup and A2 subgroup, so as to obtain a code same to an original A code. The method comprises the advantages that the sensitivity of measure precision and measure results on thresholds is reduced, the shaping threshold regulating work for rod-position measure channels is greatly simplified, the debugging and test periods for the rod-position measure channels are shortened, and phenomena such as flash and jump of rod-position display are avoided.
