Abstract

In today's world, the great changes unprecedented in a hundred years are accelerating, climate change and turbulence bring serious challenges to the survival and development of all mankind, the global energy industry chain supply chain has suffered serious impacts, the international energy price is high and oscillating, the energy supply and demand map has been adjusted in depth, and the new round of scientific and technological revolutions and industrial revolutions have developed in depth, so that the safety and efficiency of the energy and power systems, the transformation of green and low carbon, and the digitalization and intelligentization of technological innovation have become the global development trend. become the global development trend. By the end of 2022, the total installed capacity of all types of power supply in China will be 2.56 billion kilowatts, and the scale of west-to-east power transmission will reach about 300 million kilowatts. The ability to optimize the allocation of power resources is steadily improving, and the green and low-carbon transformation of power is accelerating; the installed capacity of non-fossil energy reaches 1.27 billion kilowatts, accounting for 49% of the total, exceeding that of coal power (1.12 billion kilowatts) In 2022, the power generation capacity of non-fossil energy reaches 3.1 trillion kilowatts per hour, accounting for 36% of the total power generation capacity. Among them, the installed scale of wind power and photovoltaic power generation is 760 million kilowatts, accounting for 30% of the total installed capacity; wind power and photovoltaic power generation is 1.2 trillion kilowatt-hours, accounting for 14% of the total power generation, which is 13 and 10 percentage points higher than that of 2010 and 2015, respectively. With the accelerated implementation of the construction of the Chengdu-Chongqing region of the Twin Cities Economic Circle, Sichuan economic and social development into a new round of high-speed development, Sichuan speed up the implementation of multi-energy complementary power projects and interconnection and mutual aid grid project. 2023, Sichuan energy builders "listen to the wind, explore the ground, see the water, chase the light," 18 wind power project to speed up the horse, and the wind power in Sichuan. The vast majority of the project is in the southwest region of Sichuan high-altitude mountains. Facing a series of problems such as high altitude, harsh climate, short construction period, high construction quality requirements, this paper optimizes the wind turbine foundation concrete pouring process, improves the secondary grouting mixing process, and strengthens the process control to improve the quality of the process, effectively shorten the construction period, and achieve the goal of high-quality project put into operation.
