Chapter 2011: Integrated power system of warship

"Integrated power system for warships?" In a small room, Comrade Xiao Ma heard Qin Guan's suggestion, and suddenly became surprised: "Are we going to launch this kind of project?"
Comrade Xiao Ma was originally engaged in the power system of warships. Now, after hearing Qin Guan's introduction, he immediately understood.
This is an inevitable trend in the development of ship power systems.
In the old days, the sailing era that had just started used wind-driven ships. Then, with the development of technology, steam engines appeared. This was the first revolution in ship power.
Steam engines have been in use until now, and there are still some ships in use, such as the Luda class, which can be regarded as a kind of steam engine. After the invention of the internal combustion engine, the power of ships has improved. From internal combustion engines to gas turbines, and finally nuclear power, these have greatly improved the power system of ships, which is called the second ship power revolution.
This revolution has continued until now. No one has proposed a new revolution in ship power, because their vision is not long enough. The earliest Niu Guoren Type 45 destroyer can be regarded as using this kind of integrated power system, which is already a matter of the new millennium.
Now, Qin Guan wanted to entrust this young man to host this project. Qin Guan didn't directly say anything about electromagnetic catapults. Those tall things are still castles in the sky. Superconductor technology has not yet broken through.
And the kind of integrated power system for warships to be developed now is the third revolution of warship power, which is also an inevitable result of technological development.
In the old days, there were very few electronic equipment on warships. Even with equipment such as radars, they would not consume too much electricity. Only when the Aegis system started, the power consumption of warships began to increase significantly, requiring power generation. The power is great, and at the same time, mechanical energy is needed to propel the ship forward.
At this time, there will be a contradiction, whether the ship’s independent mechanical propulsion system and power system can be combined into one in the form of electrical energy to provide electrical energy for ship propulsion, communication and navigation, special operations and daily equipment through the power network , To achieve the comprehensive utilization of energy on the ship?
What are the benefits of doing this? No matter what kind of power the whole ship uses, first of all this power is used to generate electricity. After the power is generated, energy can be transmitted through the transmission lines. For the warship, the most cumbersome drive shaft is gone. Just hang it directly behind the warship. The electric motor drives the propeller, which is of great benefit to the structural layout of the warship.
At the same time, electricity can be distributed reasonably. I need to navigate at a high speed, so I allocate more electricity to the motors. I need to search the surrounding airspace and allocate more electricity to the radar, so as to achieve reasonable and optimized utilization.
At the same time, another aspect is to prepare for the future equipment. The future electromagnetic catapults, electromagnetic arrest cables, etc., are all large consumers of electricity. At that time, the integrated power system of the ship must be required. Okay, the technology is ready.
However, with current technology, there will still be many problems.
"If we plan to do it, what technical route do we adopt?" Xiao Ma has already thought about it seriously: "The first is the issue of alternating current and direct current. How do we choose?"
Alternating current, ordinary commercial power is in use. There are quite a lot of equipment for this kind of circuit, which can be transplanted to warships. However, this kind of power supply is not suitable. Just running the same frequency of alternating current is a big problem. After all, warships are not like civilian power systems, and grid-connected power generation is a big problem.
DC power is very convenient to use, but there are almost no commercial equipment, all of which need to be self-developed, which is very difficult and uncertain.
"Medium voltage DC." Qin Guan said.
Qin Guan is very familiar with this development. In the West, Niu Country’s Type 45 destroyer, aircraft carrier, Eagle Country’s DDG1000 destroyer, Ji Country’s "Northwest Wind" class amphibious assault ship, etc. all use medium-voltage AC integrated power systems. .
Even for this kind of system, they have studied for more than ten years. Although the technology is mature, the equipment volume and weight are too large, the system efficiency is low, and the power supply continuity is not high. In terms of classification, it is called the first-generation integrated power system. .
As for Han Guo, under the research of Comrade Xiao Ma in front of him, a medium voltage DC system was developed, which greatly reduced the size and weight of the equipment, and improved the system efficiency and power supply continuity. It is called a kind of leading world in Han. Technology.
When developing the integrated power system of warships, various countries have encountered various problems. Only Han has not encountered such problems and has reached the final maturity. This shows how powerful Han's technology is.
Now, Qin Guan pointed out this plan at once. We need to bypass the medium voltage AC or low voltage AC and directly develop the medium voltage DC system.
He believed that Comrade Xiao Ma would be able to do it.
In the past, Qin Guan never thought about making arrangements in this area. After all, all-electric propulsion is a thing in the 21st century. However, since superconductors and pre-research on electromagnetic ejection are needed, if there is no all-electric Pushing forward, it was still a castle in the air, so it was all promoted. This thing originally belonged to the weapon material cemetery, and Qin Guan could easily get all these materials out.
"I have some technical information, you can take it back and study it, I hope we can make this kind of thing as soon as possible." Qin Guan said to Comrade Xiaoma.
Little Ma nodded: "Don't worry, I will work hard, but I have one more request."
Have a request? Qin Guan looked at him in surprise.
"I guess, our system must be pre-researched for the new Aegis warship, right?" Xiao Ma asked: "I have been teaching in school. I don't have time to read it. I really want to see it. Our battleship."
At present, Han is building the latest Aegis warships in China. These warships are expensive to build and have high performance, including phased array radars, vertical launch systems, gas turbine power systems, etc., and the displacement is as high as eight or nine. Thousand tons, similar to the four imported King Kong.
Although Comrade Xiao Ma is also in the navy system, the level of this kind of warship is very high. It is impossible for people with insufficient level to see it. Comrade Xiao Ma has long wanted to see it, and has never This opportunity, right now, in front of Qin Guan, expressed this idea.
