With the vigorous development of the digital economy and the rapid construction of novel power system, deeply integrating advanced digital technology with power measurement technology and building a digital power measurement smart laboratory is an important way to accelerate the construction of a modern advanced measurement system and promote the digital transformation of power measurement. Focusing on the shortcomings and challenging problems in the construction of the current power measurement system, this paper describes the overall architecture and technical system of the power measurement smart laboratory in detail. On this basis, it conducts in-depth discussions on key issues such as measurement data panorama perception, edge computing and coordinated regulation, platform interaction and data processing, cross domain integration and value-added services, security protection, etc. during the construction of the laboratory, and looks forward to the realization of the functions and values of the digital power measurement smart laboratory, hoping to provide a certain reference for the development of power measurement technology.
