National Quality Infrastructure Supports Smart Grid Construction in China-Taking the State Grid as an Example

Abstract

The National Quality Infrastructure (NQI) plays an important role in technically supporting the construction of the smart grid. Taking the State Grid as an example, this paper analyzes the role of NQI in promoting and supporting UHV transmission projects, smart grid dispatching & control systems and new energy power generation in China. In the field of UHV transmission, the standard system supports the construction and industrial upgrading of UHV transmission projects, the testing system ensures the quality of engineering equipment, and the metering service ensures the accurate settlement of power generation, transmission and power supply. In the field of smart grid dispatching, NQI supports the successful research and development, all-round promotion and efficient operation of the D5000 System. In the field of new energy power generation, the technical standard system provides the basis for the grid-integrated system of new energy power generation. The improvement of testing capability has promoted the technological progress of the new energy industry. The certification of grid-integrated new energy has maintained the fairness and authority of the quality system.
