What is the difference between the U.S. and China s power systems?

First, the frequency of power generation is different.

The frequency at which electricity is emitted in the United States is 60Hz; The frequency of electricity generated in our country is 50Hz.

Second, the civil voltage is different.

U.S. civil electricity is 110 volts; And our civil electricity is 220 volts.

Third, the electricity market is different.

China has only two utilities, State Grid and China Southern Power Grid, which are highly monopolized; And there are so many electric power companies in the United States that users can easily choose their favorite low-cost power companies. So the U.S. electricity market is the real competitive electricity market.

Fourth, the application of the tower is different.

In some places in the United States, new high-voltage transmission towers have been applied, covering a smaller area; And China is basically an ordinary high-voltage tower.

Fifth, the energy source of power generation is different.

The United States has formed three major power grid systems: Eastern, Western and Texas. The eastern part is dominated by coal and natural gas power generation; The western part is dominated by hydropower installations; Texas generates electricity from natural gas, forming a small independent power grid in the region.

China's energy resource endowment forms a unified power grid, and China is rich in coal resources, so it is mainly based on power generation.

The difference is in; The frequency at which electricity is emitted in the United States is 60Hz; The frequency of electricity generated in our country is 50Hz.

Household electricity in the United States is 110 volts. And our household electricity is 220 volts.

The voltages of industrial electricity are not the same.

The United States has done a better job in energy conservation.

In addition, the power system in the United States is very clean.

It is better to control the sudden rise and fall of voltage, harmonics, etc.

I don't know anything else.

The civil electricity voltage in the United States is 110 volts, and the civil electricity voltage in China is 220 volts.

The concept of distributed is not suitable for everything, generally speaking, the source is distributed, and the way is integrated.

The power grid is the network, and the network is not distributed, but the more holistic and the bigger the better.

The larger the power grid, the more unified the regional power grid standards, the more peak shaving and valley filling, the more unified scheduling, and the more fault tolerance and redundancy.

Distributed power supply is advanced, and distributed power grid is backward.

The United States is lagging behind.

As one of the top 500 national power grids in China, it can be said that the distributed power grid is very advanced compared with China's current power grid.

Because China is not the same as the United States.

Because each country uses a different way of generating the grid.

Perhaps China is more suitable for other distribution methods.

The population density of the two countries is different, so the distribution is different.

Because China is more suitable for the other way.

Because China has China's unique policy.

This is related to China's special national conditions.

There is no superiority or inferiority in the power grid, it is good to suit the country.
