National Energy Administration and other four departments: accelerate the research and development of high-reliability, large-capacity, low-loss direct current converter transformers, converter valves based on high-parameter power devices, and ultra-high-voltage direct current control protection systems.

The State Energy Administration and four other departments have issued guidelines on promoting the high-quality development of energy equipment. Among them, it is proposed to accelerate the research and development of key equipment such as high-reliability, large-capacity, low-loss DC converters, valve converters based on high-parameter power devices, ultra-high-voltage DC control protection systems, and super-large breaking capacity AC switches, in order to improve the efficiency and stability of long-distance, high-power electricity transmission. Speed up the research and development of advanced equipment such as first and second-class deeply integrated intelligent switches, solid-state circuit breakers, intelligent integrated terminals, high-power intelligent charging, grid-type and flexible DC, to promote the diversification of access to new distribution systems and the digital upgrade of intelligence. Promote the substitution and application of environmentally friendly green equipment such as natural ester insulated oil transformers, environmentally friendly gas high-voltage switches, and energy-efficient transformers. Develop automation control systems based on artificial intelligence, develop smart grid control software with autonomous decision-making capabilities and a new generation of distribution Internet of Things operating systems, and promote the upgrade of the smart grid intelligent control system.
