Exploration of Ultra-High-Voltage Alternating Current Power Transmission Technology Standardization for Global Energy Interconnection

The development of Global Energy Interconnection (GEI), which projects to build a globally interconnected power grid to dispatch electricity generated by renewable energy worldwide, has become a strong driving force to the electrical engineering industry. Ultra-High-Voltage (GEI), consists Alternating Current (AC) and Direct Current (DC) technologies establish the backbone of GEI and it plays an important role in GEI, and it significantly promotes the upgrade of high voltage, electronics, materials, information and other related technologies. With its fast development, there is a urgent demand for the standardization of the technologies. In this paper, we would focus on the UHV AC standardization exploration: First, we present a brief introduction of the background. Second, we demonstrate current development situation of UHV AC standards. Third, we explore the requirement of of UHV AC standards with the development of GEI. Forth, we propose the standard system from the four major areas of general and design, equipment and test, construction, and operation. Fifth, an efficient roadmap is given.
