Development status and prospect of natural gas power generation in China

It is expected that by 2025, China's installed capacity of natural gas power generation

It will exceed 150 million kilowatts, accounting for 6% of the total installed capacity

Around. Under the national double carbon goal, coal reduction and gas extraction is the future

An important measure for energy structure adjustment and carbon reduction in 10-20 years. countries

National Energy Bureau, Development Research Center of The State Council, Natural Resources

The Ministry and other departments jointly issued the "China Natural Gas Development News.

Report (2021) predicts China's natural gas consumption in 2025

The scale will reach 430 to 450 billion cubic meters by 2030

It reached 550-600 billion cubic meters, and then the gas was depleted

It will grow steadily and sustainably and enter development around 2040

The plateau period. Compare the development path of natural gas industry in developed countries

In terms of diameter, the consumption of natural gas has increased after the market has entered a mature period

Long-term power comes mainly from electricity generation. In early 2021, China gas

The installed power capacity exceeded 100 million kilowatts, accounting for the total installed power generation ratio

That's 4.5% by weight, well below the global average of about a quarter

Average level; The proportion of electricity generation is only 3.26%, which is also far lower

The global average is 23%.

Natural gas power generation is environmentally friendly and low-carbon, and has flexible operation.

The unit can start quickly, both base load power generation and peak balancing

Power generation, and easy access to the load center, improve power supply

Depend on sex. In addition, a new type of power system is constructed from the state

According to the positioning and demand of gas and electricity, gas and electricity are not only substitutes for coal

Electricity is an important component of reducing carbon emissions (international experience is also

So), it will also be supported after the proportion of renewable energy increases

The flexibility and safety of the grid are important to rely on. At the moment,

The proportion of flexible power supply in China is still low, pumped storage,

The proportion of flexible power sources such as gas power generation is only 6%,

There is an urgent need for gas power generation with high efficiency, low emissions and high flexibility

"Cheer up."

Natural gas power generation is currently mainly distributed in the economy

Adequate supply of natural gas, environmental protection and low carbon requirements

Higher Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Hebei and other regions.

During the "14th Five-Year Plan" period, we will continue to promote the process of coal to gas,

Load centers are available in densely populated large cities

Deployment of large-scale and efficient natural gas power generation; Also,

In new industrial parks and large business districts in large and medium-sized cities,

Actively develop natural gas distributed energy to achieve gas, electricity,

Cold and hot integrated supply, coordinated development. with

When, in natural gas and scenery resources rich area supporting construction

A number of gas-fired peaking power stations ensure sufficient capacity and flexibility

Start-stop power plants to regulate grid load peaks and valleys on the grid

FM service available. By establishing synergistic qi -

Wind complementary or gas-light complementary power generation mode, wind-light -

A new form of hydrogen-gas coupled power generation, improving new energy and energy

The total output level of renewable energy generation and the operation of the grid can be

By virtue of the ability and power supply delivery, the realization of gas electricity and new energy

Source integration development.

Due to the complexity of load regulation, coal power supercritical units

The load change rate is about 1.5% of the rated power.

Due to load by boiler and steam turbine and other auxiliary

The combined effect of the machine, such as the thermal stress of the cylinder block, is actually 60

The load adjustment rate of 10,000 grade coal power is about 20MW/ min

Around. Gas turbines rely on direct regulation of fuel

To adjust the load, the cylinder body ADAPTS to changes in thermal stress, there

With fast lifting load capacity, 9HA.01 lifting load

The rate is 65MW/ min, which is more than three times that of the same coal power.
