The invention discloses a verification system of digital measurement of twp kinds of intelligent substations, in order to solve the following problem in the prior art: when the intelligent substationsperform measurement statistics, various devices are not in the same device, and single calculations are performed to lead to relatively large errors. The verification system disclosed by the invention comprises a collection unit, a forwarding unit and a calibrator; the collection unit collects an output pulse signal of an electric energy meter, the forwarding unit sends the pulse signal to the calibrator, the calibrator collects an analog signal of the voltage/current of a transformer, and calculates errors according to an electric energy value of a voltage/current signal and the electric energy value of a pseudo voltage. The invention further discloses a verification method of digital measurement of intelligent substations. The method comprises the steps of: firstly, collecting the pulsesignal of the electric energy meter and a secondary voltage and secondary current output by the transformer; then, calculating the electric energy values of the pulse signal, the secondary voltage and the secondary current; and finally, calculating errors according to the electric energy values of the pulse signal, the secondary voltage and the secondary current. The verification system disclosedby the invention has the advantages of having high measurement accuracy, saving procedures, reducing the cost, etc.
