Unit power signal acquisition device and unit power signal screening method and system

The invention relates to the technical field of power plant unit adjustment, in particular to a unit power signal acquisition device, a unit power signal screening method, a unit power signal screening system and related equipment. According to the unit power signal acquisition device provided by the invention, at least three power transmitters are arranged to acquire the unit power signal and the channel quality state thereof, so that the error-tolerant rate of a unit power feedback value can be improved from a hardware loop, the redundancy of power feedback is increased, and the problems of single power signal and incapability of redundancy in a traditional acquisition mode are solved; according to the unit power signal screening method provided by the invention, the collected multiple paths of power signals can be analyzed and processed, and the optimal path of power signal is selected as the final power feedback value, so that the accuracy of power optimization is remarkably improved, the output of the op
