With the construction of State Grid informatization, cyberspace security incidents occurs frequently. Therefore, it is important to develop secure and reliable quantum communication technologies for the power grid. In this paper, from the perspective of the multi-terminal quantum key application, a handheld meter reading solution based on quantum private communication technology is proposed to effectively achieve the technological upgrading. First, from the technical theory and application fields, the current situation of quantum private communication technology and its feasibility of combining with classical facilities are introduced and analyzed. Then, considering the quantum key management system as the core, we design and implement quantum key secure storage and business security process application model. Finally, based on the overall environment of quantum key distribution, the architecture design of multi-terminal quantum key application verification is implemented to verify the quantum key business application process.
