Domestic brains fill the gaps, and more than 30 key devices use "domestic brains".
Due to the later promotion of scientific and technological development, China has faced"Lack of core and soul reduction"Now, with the efforts of Chinese enterprises and R&D personnel, these problems are gradually being overcome.
Not long ago, there was heavy news in China that Chinese companies set up R&D teams to overcome key technologies and independently develop technologies to fill the domestic gap30 key pieces of equipment are available"Domestic brains", foreign media commented: Everything is solved.
As we all know"Lack of core and soul reduction"As the name suggests, it describes chips and systems, the former as the pillar of today's information age, the demand is increasing day by day, and our country has to import hundreds of billions of dollars every year.
Shanghai SMIT Lithography Machine, SMIC Chip Foundry and other companies have been actively developing more advanced technology and expanding domestic chip production capacity to achieve the goal of 70% self-sufficiency.
The latter is known to many people"Brain"Whether it is the various control systems of large-scale equipment or the operating system of intelligent devices, they have long relied on the products of Western developed countries.
The most common are mobile phones and computers, relying on Huawei's HarmonyOS system, Google's Android system, Microsoft's Windows system and Apple's iOS system before that, which almost monopolized the entire market.
It wasn't until the emergence of the domestic Hongmeng system that the Unicom UOS system really had its own"Soul", began to get rid of dependence on American technology, and became an important milestone on the road to autonomy.
Of course, this is only the tip of the iceberg, including armored machinery, heavy gas turbines and other important national basic technologies and control systems, are constantly being developed and improved.
The most interesting thing is that not long ago, China's Southern Power Grid Energy Storage Company officially announced that it had independently developed the first set of core equipment control system"The idea of the country"Officially put into practice.
According to reports, the breakthrough is"Core control system of pumped storage unit", through the monitoring, speed regulation, excitation, relay protection of the four requirements, known as pumped storage"Brain"。
Pumped storage is the key equipment of pumped storage power station, which provides great benefits for China's energy production and is one of the most important equipment in the country.
Compared to thermal and nuclear power generation, pumped hydro is a more environmentally friendly way to generate electricity, not only because it does not emit greenhouse gases and atmospheric pollutants such as carbon dioxide, nitrogen oxides and sulfur oxides, but also because it does not produce nuclear waste that is difficult to dispose of.
The process of generating electricity is also very easy to understand: the pumped storage power station consists of two reservoirs, one at the top and one at the bottom. When electricity is in short supply, the energy system uses the excess energy to pump water from the lower reservoir to the upper reservoir.
Conversely, when electricity is in short supply, pumped storage power plants meet the needs of the energy system by releasing stored water so that it flows down the upper reservoir and is turned by turbine generators to generate electricity.
Until then, the control system of this important national facility used basic technology supplied from abroad, which not only required high annual licensing fees, but also the possibility of blocking"Strangling", because important state equipment clearly does not have a sufficiently high level of security.
In order to solve this problem, China Southern Power Grid Energy Storage Co., Ltd. took the lead in setting up a R&D team to target"Less soul"After two years, 40 key technological innovations have achieved constructive results.
It has created the first set of pumped storage control system in China, which not only fills the gap in China, but also makes China's performance level in the field of speed regulation and excitation system equipment reach the world's leading level.
It is worth mentioning that this"Domestic brains"It has accumulated more than 17,000 hours of operation, passed relevant tests, and has been continuously put into use on more than 30 machines in 7 pumped storage power stations.
However, there are still many necessary equipment that have not yet been localized and are still suffering from the blockade of Western technology, so the revolution is not over yet, and comrades still need to work hard.
Even if we are already lagging behind the West, as long as our scientific research team is united, one day we will catch up with other countries, just like the opinion of the foreign media: this is all sorted out a long time ago!
