Zhao Xizheng, Chairman of the China Electricity Council, recently revealed that the total scale of China's power grid has ranked first in the world, and the construction of power sources and power grids has preliminarily achieved coordinated development.
At present, the circuit length of 220 kV and above transmission lines in China has reached 328400 kilometers, an increase of 14.66% compared to the previous year; The capacitance of 220 kV and above transformers reached 12.3 KVA, an increase of 22.36% compared to the previous year. The experimental demonstration projects of 1000 kV AC ultra-high voltage and plus or minus 800 kV DC ultra-high voltage are about to be completed. The total transportation capacity of the three major channels has reached 47.5 million kilowatts.
