vivo mobile phone time settings: enter mobile phone settings--system management/more settings--date and time, you can turn on automatic settings, and it will automatically time after connecting to the Internet. You can also turn off automatic settings, set time, and manually enter time and date.

How does the power system adjust the frequency?

1. Under normal circumstances, the total active power emitted by the generator in the power system and the total active power consumed by the load are balanced, and the system frequency can be maintained at the rated value. The change of system frequency directly reflects the balance of active power. The sending is greater than the use, and the frequency of the system increases.The use is greater than the one sent, and the system frequency is reduced.

2. When the active power emitted by the power grid is equal to the user's active load, the frequency remains unchanged; when it is less than the active load, the frequency decreases; when it is greater than the active load, the frequency rises. Therefore, changing the active power output of the generator can adjust the frequency of the power grid.

3. The first FM is fast, but it can only be adjusted with differences and cannot fully compensate for the change of load, so the system frequency will still have a certain shift. Secondary FM refers to the human adjustment of the power of the generator to compensate for the lack of primary FM and restore the system frequency to the rated value.

4. The basic principle of primary FM of the power system: the frequency of the power grid is determined by the size of the power generation power and the power consumption load. When the power generation power is equal to the size of the power consumption load, the frequency of the power grid is stable;When the power generation power is greater than the power consumption load, the frequency of the power grid increases; when the power generation power is less than the power consumption load, the frequency of the power grid decreases.

5. First of all, frequency response means that when the power system is subjected to external disturbance, it adjusts the output of the generator through corresponding control measures to keep the system frequency stable. Common frequency response methods include rate power control, AGC (Automatic-Generation-Control) and Primary-Frequency-Response, etc.

What to do if the file is invalidated and the computer system adjustment

Prepare the installation media: Get the installation media suitable for your operating system version, which can be a CD-ROM, USB flash drive or downloaded image file.Start the computer and set the boot order: insert the installation media and restart the computer.

When the computer cannot enter the system, restart the computer first, and press [F8 key] to enter the system safe mode when restarting the computer. If the laptop does not have a restart button, press the power button for a long time to force the shutdown, and then restart it.

You can try the following solutions: try to use the system recovery point. You can enter "Safe Mode" (press the F8 key) and then select "Recently Available Recovery Point" to restore the system, which can help you restore the state of the last normal operation of the system. Use the system installation CD to repair.

Remedy: There are two situations: First, the lost files have a great impact on the computer and affect the normal operation. It is recommended to restore the system or reinstall the system to find the lost normal files.Second, the impact is not very big, so don't worry about him.
