What are the effects of frequency variation on power users and power systems?

What are the effects of frequency variation on power users and power systems?

Answer:

1, the use of motor speed and system frequency, the frequency change will make the motor speed change, thus affecting the quality of the product. For example, the textile industry will change because of the frequency of defective products.2, modern industry, national defense and science and technology have been widely used in electronic equipment affected by frequency.System itself:1, low frequency operation, the generator will be affected by the stress of the blade. Even cause resonance, reduce blade life.2, increase the excitation current, improve the temperature rise, etc..
Power frequency: generally refers to the frequency of electricity market, China's power industry, the standard frequency of 50 hz. Some countries or regions, such as the United States, are set at 60 hz.
As we all know, the asynchronous motor is widely used in industry. Its speed and output power are related to frequency. Changes in frequency, speed and power output of the motor is also changing, which seriously affected the quality of the product; modern industry, national defense and scientific research has been widely used in various electronic technology equipment, if the system frequency instability, affect the accuracy of these devices will be.
Influence of frequency variation on power users and power systems:There is a close relationship between the frequency of power equipment and the operation of power system
