In addition, according to the purpose and use of diesel generator sets, they can be divided into standby generator sets, common generator sets, war-ready generator sets and emergency generator sets.

Generator Sets

1. Standby Generator Sets

Under normal circumstances, the power required by users is supplied by the city power. When the city power limit is disconnected or other reasons interrupt the power supply, the generator set is set up to ensure the basic production and life of users. This type of generator set is located in important power users such as industrial and mining enterprises, hospitals, hotels, banks, airports and radio stations where the city power supply is tight.

2. Common Generator Sets

This type of generator set operates all year round and is generally located in areas far away from the power grid (or city power) or near industrial and mining enterprises to meet the construction, production and living electricity needs of these places. At present, in areas with relatively rapid emergency development, common diesel generator sets with short construction periods are needed to meet the needs of users. This type of generator set generally has a large capacity.

3. War-ready generator sets

This type of generator set is used to supply power to civil air defense and national defense facilities. It has the nature of a standby generator set in normal times, and has the nature of a common generator set after the city power is destroyed in wartime. This type of generator set is generally installed underground and has a certain degree of protection.

4. Emergency generator set

For electrical equipment that will cause major losses or personal accidents if the city power is suddenly interrupted, emergency generator sets are often set up to provide emergency power to these equipment, such as fire protection systems, evacuation lighting, elevators, control systems of automated production lines, and important communication systems in high-rise buildings. This type of generator set needs to be installed with a self-starting diesel generator set, and the degree of automation is required to be high.

The above are some basic classifications of diesel generator sets. Users can choose suitable diesel generator sets according to their needs and suitable environments. For the use of diesel generator sets, in addition to the correct selection of matching models, regular maintenance is also required in later use.

On August 22, the Institute of Electrical Engineering of the Chinese Academy of Sciences learned that after five years of technical research and engineering construction, the first supercritical carbon dioxide solar thermal power generation unit was successfully developed. The third-party test results show that the power generation power, heat-to-work conversion efficiency and other indicators of the generator unit fully meet the requirements of the project task book.

It is reported that the generator unit was developed with the support of the “Research on Key Basic Issues of Supercritical Carbon Dioxide Solar Thermal Power Generation” project. The project recently passed the project performance evaluation organized by the National Natural Science Foundation of China. After five hours of defense and expert questioning, the expert group gave a high evaluation of the project and recommended its promotion and implementation.

In recent years, my country’s solar thermal power generation industry has shown a booming development trend, but the cost of solar thermal power generation has not fallen as expected. Supercritical carbon dioxide solar thermal power generation technology, as the most potential low-cost, high-efficiency and high-flexibility technology, has attracted widespread attention from global research institutions and industries.

“However, the core equipment used in supercritical carbon dioxide solar thermal power generation technology, such as high-temperature particle absorbers and supercritical carbon dioxide generators, are in the research and exploration stage worldwide.” said Wang Zhifeng, project leader and researcher at the Institute of Electrical Engineering of the Chinese Academy of Sciences.

Over the past five years, the project team has focused on engineering design, organically integrated basic theoretical research, technical equipment development and system integration, and actively promoted scientific research and empirical engineering construction.

“We have overcome the difficulties in designing and manufacturing core equipment such as solar high-temperature particle heat absorption, fluidized bed particle/carbon dioxide heat exchange, and 200-kilowatt supercritical carbon dioxide generator sets. We are the first in the world to realize the operation of supercritical carbon dioxide solar thermal power generation systems including high-coke ratio focusing fields, particle heat absorbers, particle/supercritical carbon dioxide heat exchangers, supercritical carbon dioxide compressor turbine units and high-speed motors.” Wang Zhifeng said that the project will effectively promote the development of my country’s “low-cost-high-efficiency-high-flexibility” solar thermal technology and provide technical support for the construction of my country’s new energy bases.

Since the beginning of summer, the Jiangnan region has been hot and humid, and the demand for electricity has continued to increase. In mid-August, in the machine room of Jiangsu Zhenjiang Gas Thermal Power Co., Ltd., a gas-fired generator set with a rated power of 485 megawatts was running at high speed. Here, the natural gas supplied by the natural gas sales company converts the heat energy generated by combustion into mechanical energy, drives the generator to rotate, and generates electricity. These clean electricity flows into the power grid continuously, providing thousands of households with a “cooling recipe” to relieve the summer heat.

In recent years, natural gas power generation has received more and more attention on the stage of power supply. As one of the provinces that actively promotes the integration of gas and electricity, Jiangsu Province has always been at the forefront of the country in the natural gas power generation industry. Why is natural gas power generation so popular in Jiangsu? What kind of development process has natural gas power generation in Jiangsu experienced? What role has the natural gas sales company, as the main gas supply, played in ensuring supply? What practical experience has been formed? With these questions, the reporter conducted interviews and investigations to explore the “Jiangsu example” of gas-electricity integration development.

In 2023, my country’s natural gas consumption continued to grow. Among the four major gas-using areas of urban gas, industry, power generation, and chemical industry, power generation gas accounted for about 17%. From the perspective of Jiangsu Province’s natural gas consumption in 2023, power generation gas accounted for 30.4%, far exceeding the national average. The information obtained by the reporter during the interview showed that Jiangsu has a high degree of gas-electricity integration and has made great efforts to promote natural gas power generation.

Jiangsu’s gas-fired power generation is closely related to Jiangsu’s regional characteristics. A relevant person in charge of the Economic Operation Bureau of the Jiangsu Provincial Development and Reform Commission said: “Jiangsu has a developed economy, but a dense population and a high per capita energy consumption base. It faces challenges such as energy shortages and great pressure on environmental protection. The orderly promotion of gas-fired power generation projects is of great significance to promoting energy conservation and emission reduction and ensuring power supply.”

Tracing the development of gas-electricity integration in Jiangsu, the reporter found that Jiangsu’s previous power generation structure was relatively simple and highly dependent on coal-fired power. In 2004, the West-East Gas Pipeline was put into operation, allowing the eastern region to use the natural gas produced and transported by the Tarim Oilfield of China National Petroleum Corporation, which provided an opportunity for Jiangsu to optimize its power structure. Since then, natural gas pipelines, LNG receiving stations and corresponding supporting facilities have been gradually established in Jiangsu Province, allowing the natural gas industry to develop vigorously from scratch.

Thanks to the development of the natural gas industry, gas-fired power plants have sprung up like mushrooms after a rain. In 2005, the gas-fired power generation unit of Zhangjiagang Huaxing Electric Power Co., Ltd. was successfully connected to the grid once, becoming the first gas-fired power plant in Jiangsu. To date, Jiangsu has 39 power plants with gas-fired power generation capabilities.

Zhangjiagang Huaxing Electric Power Co., Ltd. is the first power plant supplied by PetroChina in Jiangsu. From supplying gas to 1 power plant to supplying gas to 37 power plants, PetroChina supplies gas to almost all gas-fired power plants in Jiangsu. Since the gas supply began in 2005, PetroChina’s resource input in the gas-fired power market in Jiangsu Province has increased year by year, reaching nearly 10 billion cubic meters in 2023, accounting for more than 90% of the gas used for power generation in Jiangsu Province.

During the investigation, the reporter walked into one of the power plants-Nanjing GCL Gas Turbine Thermal Power Co., Ltd. (referred to as Nanjing GCL). There are no towering chimneys here, nor can you see the rising “white smoke”. According to Xiao Youjun, director of the business planning department of Nanjing GCL, this is a power plant that “consumes” natural gas completely. Compared with coal-fired power plants of the same capacity, sulfur dioxide emissions have been reduced by about 90%, and smoke emissions have been reduced by about 100%, with significant benefits in environmental protection.

Facts have proved that in the past 20 years, Jiangsu has made every effort to promote the optimization of energy structure and green energy transformation, and the natural gas power generation industry has developed steadily. The development of PetroChina’s natural gas power generation-related business in Jiangsu has also achieved a huge leap.

Data shows that Jiangsu Province is one of the provinces in China with a large number of power plants and gas resources for power generation, which shows the natural gas sales company’s high attention to the natural gas power generation market in Jiangsu and its confidence and determination to find a path for the integration of gas and electricity.
