Large scale access of new energy source and nonlinear load, increasing the dynamic characteristics of grid metering method, has brought new challenges to the existing power metering method. In order to solve the dynamic electric energy metering method of the biggest problems -- the traceability problem, this paper starts from the analysis of the dynamic characteristics of the signal, and the characteristics of dynamic signal extraction and mathematical modeling, presents a detailed method of electric energy meter dynamic performance measurement, and analyzes the characteristics of the source, to ensure that the dynamic performance of value accurate, reliable, dynamic signal of the electric energy measurement traceability provides a new idea and technology to explore ideas.
