The invention discloses an electric energy measuring device state evaluation method and system based on an order relation analytical method. The electric energy measuring device state evaluation method includes the steps that operating state evaluation is carried out on a plurality of subparts of a to-be-evaluated electric energy measuring device correspondingly, wherein the subparts of the electric energy measuring device comprise an electric energy meter, a current transformer, a voltage transformer and a secondary circuit; according to historical data of the to-be-evaluated electric energymeasuring device, the importance degrees of the subparts are determined; according to the importance degrees of the subparts, the weights of the running states of the subparts in the running state ofthe electric energy measuring device are obtained through a preset rule; and according to running state evaluation results of the subparts and the corresponding weights of the subparts, a state evaluation result of the to-be-evaluated electric energy measuring device is obtained. According to the electric energy measuring device state evaluation method and system based on the order relation analytical method, comprehensive evaluation of the electric energy measuring device is realized through the order relation analytical method, the one-sidedness of state evaluation of the electric energy measuring device is avoided, and the test working efficiency and accuracy are improved.
