Power grid: support Sichuan-Chongqing power supply to the maximum extent. Why are there frequent power outages in Chengdu?

Frequent power outages in Chengdu are mainly due to the increase in the proportion of new energy generation under the background of double carbon, but the gap between supply and demand between power generation and electricity consumption is always difficult to balance. Coupled with the aging of some local lines, unreasonable planning of some power systems in the past, increased demand for electricity in summer, and Sichuan's responsibility to deliver hydropower to other provinces, Chengdu will often lose power due to these factors. According to the local report of Sichuan Daily, since August, the incoming water of hydropower in Sichuan has dried up by 50%, and the supporting capacity of hydropower and power supply has dropped significantly.

At the right time, in the case of declining power supply capacity, Sichuan's hydropower still needs to be sent to other provinces. Has Sichuan Province been formed now? Five straight and eight horizontal? In Sichuan Province, most transmission areas, including East China, Northwest China, North China, Central China and Chongqing, account for 9. 14% of the total transmission value of all provinces in China.

In the case of insufficient power supply, most power grids will give priority to supplying power to streets with large crowds and high grades. Major factories will also adopt timing transmission. In order to balance the power demand. Another main reason is the line load. Any area has its maximum load. If the load is exceeded, the power grid must take the initiative to pull the switch. And this reason will not be solved for a while, and this is it. Problems in the transmission hardware must be escalated to all power configurations in the area.

However, with such a large regional base, it is obviously impossible to upgrade all of them at once and replace them with new ones. Therefore, only targeted maintenance and upgrading can be carried out, and the load of the line should also be considered. Therefore, the power grid has always advocated that everyone use electricity at wrong peaks and save electricity. Many blackouts are due to failures, which is also due to the problems of grass-roots construction and lines, which exceed the load that the lines can bear, and are naturally prone to failures.
