For a large number of transient, dynamic, steady and electric power data generated in the operation of power system, a power information verification method based on grid three-state data is proposed. The new accurate target function of dynamic total wave active power and time is fitted by collecting the active power information of steady state total wave active power and dynamic base wave. The amplitude of electric quantity is calculated and compared with the information collected at the same time period, so that the amplitude of electric quantity is verified. Transient voltage and current information is collected. Then the transient active power is calculated. The objective function of active power and time is fitted. The target function of electric quantity and time is converted by calculation and compared with the collection information of electric quantity, so that the time offset of electric quantity is verified. The data points with wrong power collection are removed. A calibration technique and method for data quality control and rapid elimination of incorrect power collection points is provided. A powerful analytical diagnostic method is provided to production schedulers. This paper is supported by an in-depth research project based on grid three-state data fusion and verification technology. Accuracy analysis of electric quantity is the key to the reliable development of power supply enterprises. The accurate analysis of electric quantity is of great significance to the project investment and production management of electric power enterprises.
