The invention relates to a power control method for an electrolytic aluminum system that is not grid-connected and multi-energy coordinated power supply. The electrolytic aluminum system includes an electrolytic aluminum device, a wind power generation device and a solar power generation device. The grid-connected form supplies power to the electrolytic aluminum device, and the waste heat emitted by the electrolytic aluminum device is recovered to generate power and supplied to the aluminum electrolytic cell; during the day, the electricity supplied by the public grid to the aluminum electrolytic cell is the minimum amount required for heat preservation operation, The electricity generated by the wind power generation device and the solar concentrating power generation device is used as a supplement; at night, the restriction on the electricity supply of the electrolytic aluminum device by the public grid is canceled. This method can adapt to the fluctuation of wind power and solar power generation, and can make full use of the peak-valley power price difference of the public grid to improve the economic benefits of the enterprise, and can assist the public grid to perform peak regulation and reduce the peak load caused by the large difference between the peak load and the low-valley load. difficulty.

The invention provides a constructing method of a prefabricated lifting column and lifting beam combined frame structure.
