With the rapid development of electric Internet of Things, electric power enterprises have increasing demands on information acquisition and processing ability, power grid management ability and information interaction ability. In order to further fit the future trend of power grid construction and solve many problems such as the accurate identification of the relationship between households and changes in the low-voltage distribution network, current fingerprint communication technology has been gradually widely used. At present, it is mainly applied in the equipment such as external circuit breakers, intelligent measuring switches and smart meters. However, there is no mature testing method and testing equipment to test the performance of current fingerprint communication. Therefore, this paper mainly studies the evaluation technology of current fingerprint communication. Through the design of system evaluation architecture, the acceptance capability, emission capability, consistency and application practice of current fingerprint communication are comprehensively evaluated and tested, and the application indicators and detection indicators of various aspects of current fingerprint communication technology are studied.
