With the power of independent innovation, State Grid Corporation dares to think, act, and be the first in the world, from ultra-high voltage to global energy Internet, from “three sets of five” to “three centers”, in ultra-high voltage, large power grid, smart grid A series of major technological breakthroughs have been made in the fields of new energy, new energy and equipment manufacturing, and the transition from technology following to technology catching up has been completed, realizing “China’s creation” and “China’s leading”, ranking second in the Fortune Global 500 No. 1 in the list of “China’s 500 Most Valuable Brands” in 2016.


The innovation of power grid technology innovation should first talk about UHV technology. my country has built “three ACs and four straight” and is under construction of “four ACs and six straight” UHV projects. The construction and operation of UHV projects have enabled Chinese power technology to occupy the commanding heights of high-voltage power transmission in the world. “Key technologies of UHV AC transmission, complete sets of equipment and engineering applications” won the special prize of the National Science and Technology Progress Award, and achieved innovative breakthroughs in 6 aspects of voltage control, external insulation configuration, electromagnetic environment control, complete set of equipment development, system integration, and testing capabilities; The key technology of high-voltage DC circuit breakers has solved the “century-old world problem” of reliable shutdown of DC fault current under high-voltage and high-current operating conditions; 44 research projects of 6 categories of major special projects of large power grids have been completed, and the system has mastered AC-DC hybrid power. The power grid operation control technology of the United Nations University has established a power grid security early warning, decision-making and control system.


State Grid puts innovation at the core of the company’s overall development, comprehensively promotes technological innovation, business innovation, and management innovation, stimulates the vitality of grass-roots “mass entrepreneurship and innovation”, and builds an innovative enterprise. Won 1 first prize and 7 second prizes of the National Science and Technology Progress Award. Zhangbei National Wind and Wind Storage and Transmission Demonstration Project won the 4th China Industry Award. Xiangjiaba-Shanghai ±800kV UHVDC Demonstration Project won the National Quality Award for Outstanding Projects. 3 projects won the first prize of China Standard Innovation Contribution Award. Has 18 national laboratories. The number of patents owned and the number of invention patent applications ranked first among state-owned enterprises for five consecutive years. New technologies such as big data, cloud computing, Internet of Things, and mobile Internet are widely used in power grid development and power supply services. Lu Qiang, a professor of the Department of Electrical Engineering of Tsinghua University, is no wonder, academician of the Chinese Academy of Sciences and a foreign academician of the Royal Swedish Academy of Engineering Sciences, said: “China now has the top status of the ‘three highs’ in the world, which is recognized and unshakable, that is, the high arch dam, High-speed rail and high voltage.”


It is hoped that State Grid will adhere to the five development concepts of innovation, coordination, greenness, openness, and sharing, persist in entrepreneurship and unswerving, persist in the pace of development, and accelerate the construction of a modern company with “one strong and three generations”.
