There are many types of conventional generators. In principle, it is divided into synchronous generator, asynchronous generator, single-phase generator and three-phase generator. From the production mode, it is divided into turbogenerator, hydrogenerator, diesel generator, gasoline generator, etc.Divided into thermal generators, hydroelectric generators and so on.1. Power supply shortage – Due to extreme weather conditions, the pace of power supply has been out of sync for a long time. In 2021, more than 4% of the world’s population – at least 350 million people – experienced catastrophic power outages as new power supply difficulties erupted on top of pre-existing ones.
At present, it is widely used in communication, posts and telecommunications, banks, hotels, airports, hospitals, schools, industrial and mining enterprises and other important departments, when the mains power outage, relying on diesel generators to automatically generate electricity, provide AC power, to ensure that communication equipment or lighting, elevators and other electrical appliances electricity. Diesel generator sets are widely used, mainly because it has the following advantages:
1) High thermal efficiency. High thermal efficiency, that is, low fuel consumption, good economy, the highest effective thermal efficiency has reached 46%.
2) Wide power range. Single power can be from a few points to tens of thousands of kilowatts, wide range of application.
3) Compact structure, light weight, the ratio of the mass of the internal combustion engine to its calibrated power (called the specific mass) is small, easy to move.
4) Start quickly, easy to operate, and can reach full load operation soon after starting.
In the use of diesel generator set, because the diesel generator set also has certain shortcomings, so the user should pay special attention to the regular maintenance of the unit, in order to effectively extend the service life of the unit, so what are the shortcomings of the diesel generator set?
1) Higher requirements for fuel. Diesel generator sets generally use light diesel as fuel, and the cleanliness of the fuel is very strict. It is difficult to use solid fuel or inferior fuel inside the cylinder. The user must choose the appropriate fuel according to the regulations, and check the fuel regularly, if the fuel is found to be deteriorated, it should be replaced in time.
2) Exhaust pollution and noise cause public hazards. Since the diesel generator set is now widely used in various fields of the national economy, its output and retention are very large, and the pollution of the environment is becoming more and more serious, so the user must do a good job in the use of the diesel generator set emissions treatment and noise reduction treatment.
3) The structure is more complex, the parts of the diesel generator set have higher processing accuracy requirements, and the use of lubrication work should be done to prevent excessive wear of parts, resulting in unit damage.
Based on the advantages and disadvantages of diesel generators, in recent decades, in order to improve the power, economy and reduce the requirements of exhaust gas emissions and noise, generator manufacturers have carried out research on new technologies, especially the application of electronic technology, and invented new generators, which will replace traditional generators. There are also many opportunities for new energy generators:
1. Power supply shortage – Due to extreme weather conditions, the pace of power supply has been out of sync for a long time. In 2021, more than 4% of the world’s population – at least 350 million people – experienced catastrophic power outages as new power supply difficulties erupted on top of pre-existing ones.
2. Increasing construction activity Many tools of different sizes commonly used in the construction industry, such as drives, drilling RIGS, air hammers and compressors, are powered by portable generators. France is the European country with the most residential construction in 2021, with more than 471,000 units built, followed by Germany with 310,000 units built.
3. Increasing urbanization and industrialization According to the United Nations Population Fund, the global urbanization rate is reaching a record high. By 2030, about 5 billion people will live in cities and towns, more than half of the world’s population today.
4. Growing awareness of global warming – Many portable generators use biofuels, which have less impact on the natural temperature of the atmosphere. Generators can provide small households with high bioethanol production as a biofuel. According to NOAA’s 2021 Annual Climate Report, total land and ocean temperatures have risen by an average of 0.14°F(0.08° C) per decade since 1880. However, the average growth rate since 1981 has been more than twice that: 0.32F(0.18°C) per decade.
5. Aging grid infrastructure Given that the grid is aging and no longer able to meet the world’s energy needs, the demand for generators is bound to be greater. However, this problem has also been solved by integrating smart grid networks. About 70 percent of transmission and distribution lines in the United States are past the first 50 years of their expected life.
6. Noise and environmental pollution of traditional power stations.
