Design of low frequency smart electric energy meter calibration system

Flexible low-frequency power transmission technology is an advanced transmission technology to solve the problem of new energy delivery such as offshore wind power. Low-frequency electric energy metering technology is an important technical support to ensure the commercial promotion and application of flexible low-frequency power transmission projects. Aiming at the technical gap in low-frequency electric energy measurement and traceability, this paper designs a new low-frequency smart electric energy meter calibration system. By designing signal sources, power amplifiers, and standard meters, it meets the measurement and traceability requirements of smart electric energy meters in the range from low frequency to power frequency.
