Why can "power failure in evening self-study" only become an unforgettable memory now

a generation will eventually graduate, and there are always people studying by themselves in the evening. Do you still remember the grand occasion after the power failure of self-study on those new year's Eve? Is it possible to think of it and cheer secretly? Recently, this topic with a sense of time has been hot searched, which has triggered the collective memories of more than 40million friends. Everyone is feeling that the power failure of self-study in the evening always calls every second, and the dark free time is fleeting. But now children probably don't know what kind of experience it is. Why can the power failure of self-study in the evening only become an unforgettable memory? How hard is it to cut off power

then focus on the city. According to relevant reports, as early as 2018, the power supply reliability index of 14 mega cities and above in China continued to improve, and the power supply reliability rate reached more than 99.95%. The latest data shows that since this year, the power supply reliability rate of Shanghai has reached 99.9956%, and the power supply reliability rate of the central urban area has achieved a breakthrough of five nines (i.e. more than 99.999%) for the first time, reaching 99.9998%. The reliability rate of power supply has reached five nines, which is the world's recognized standard for measuring the hardest core of first-class electricity, and has been achieved in China. In China, power failure has become an extremely small probability event

behind the unforgettable memories and hard core data, there are higher requirements for the high quality, sustainability and resilience of power supply in the face of failure. If you want to achieve the level of five nines of power supply reliability, the average annual household power failure time of customers in the region will be less than 0.4 minutes, which means that after power supply failure, power distribution can quickly call through a series of intelligent means, and ordinary power customers can hardly feel this process.
