STATE GRID: OCCUPY THE COMMANDING HEIGHTS OF THE WORLD’S POWER GRID TECHNOLOGY WITH INNOVATION

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. High-efficiency and innovative surge arrester can better provide the safety of power transportation.

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”.
