Advantages and disadvantages of thermal power generation and hydroelectric generation

Firepower:

Advantages: The technology is mature and the current cost is low. Low geographic environment requirements.

Disadvantages: high pollution, poor prospects for sustainable development. It consumes a lot of energy and has low efficiency.

Hydraulic power:

Advantages: long history, low subsequent costs. No pollution, renewable water energy, large total water energy reserves.

Disadvantages: large capital investments and high requirements for geographical environment. For example, southwest China is extremely rich in water resources, but the natural environment is harsh and construction is difficult, making its use impossible. them.

Detailed information:

< p>Electricity production involves converting water energy, energythermal energy from fossil fuels, nuclear energy, solar energy, wind energy, geothermal energy, ocean energy and other energies into electrical energy through the use of electricity generation devices. By the end of the 20th century, most electricity generation used the method of burning fossil fuels. However, fossil fuel resources are not abundant and are becoming increasingly depleted. At present, humans are gradually using renewable energies (hydraulic energy, solar energy, energy). wind energy, geothermal energy, marine energy, etc.) to produce electricity.

The basic principle of hydroelectricity is to use the difference in water level to produce electricity with a hydroelectric generator, that is, the potential energy of water is converted into mechanical energy of the water wheel, then into mechanical energyeu. mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use an electricity cheap and pollution-free.

Thermal power generation generally refers to the use of thermal energy generated when fuels such as oil, coal and natural gas are burned to heat water, transforming the water into water vapor at high temperature and high pressure, and then use the water vapor to drive a generator to produce electricity. The general name of the method. Power plants that use coal, oil or natural gas as fuel are collectively called power plantsthermal.

First, power generation companies should strengthen their hardware investment through scientific means such as their own water regime forecasting systems, to more accurately predict watersheds. Water inflow trends, understanding and being well aware of the direction of reservoir distribution; secondly, we need to strengthen the statistical analysis of water regime data, standardize, institutionalize and routine analysis work, strengthen the professional quality and responsibility of analysis work. and statistical personnel, and provide excellent “software” to better predict the trend of water inflow into the basin; third, we need to establish an optimized distribution work mechanism, integrate optimized distribution into daily work, propose strshort and medium term strategies for safeguarding and functioning of the unit, develop the best operating plan and implement it. In terms of daily operation mode, it should be implemented at the time of operation of power generation, charging rate and water consumption rate. Fourth, we must do a good job; in the maintenance of the unit, take full advantage of the dry season to repair and maintain the equipment, and ensure that the unit produces electricity at full load during the rainy season, the equivalent availability coefficient is notably 100%. a plan must be developed to ensure that no water is released or less water is released into the reservoir; Fifth, it is necessary to fully and frequently contact the dispatch department of the provincial power grid company to understand the best operation methods and intentions of the company.taken.It is necessary to communicate, share forecasts and results of analysis of the water regime, obtain understanding and support. It is necessary to achieve the best use of water energy while ensuring the security of the electricity network and peak regulation, and to achieve the balance between safe dispatch. of the electricity network and optimal functioning of the reservoir Harmony and unity, win-win and win-win situation.
