After roughly scanning, Zhang Yifu figured out the situation as soon as several sets of data were unfolded.

Jiutan Power Plant, the entire plant unit tripped and the load was 890,000 KW, causing the frequency of the power grid to drop sharply from 50.05Hz, causing the nearby frequency modulation power plant to triple and drop 390,000 KW, resulting in the loss of 1.29 million KW of power in the province's power grid, 23% of the power generation power in the entire network, and the system frequency was reduced to 48.93%.

This series of data and terms are very professional, and power grid experts need to understand it for a while, not to mention the people from the power plant, not to mention the newcomer Zhang Yifu. But the current situation is-

That's how he understood it, and Duan Youwei thought he must have understood it.

Trouble...

If you throw away those professional terms, this is actually a very simple question.

An accident occurred in a power plant and the units were shut down, which led to problems with the voltage of the entire power grid and the region, which forced the power plant specifically responsible for adjustment to make some reactions to recover. As a result, the guy who saved the people fell into the water. The power grid in the province lost 23% of the power generation power, and 1/5 of the province's area fell into darkness.

Fortunately, this darkness lasted for less than half an hour, and Jiutan Power Plant quickly solved the problem.

Even so, it was still a very serious accident.

Electricity accidents are not ordinary industrial accidents. It is not that if this equipment explodes and that equipment is burned, it is an accident. Of course, equipment damage is an accident, but the most serious accident is that it is a power outage for users, delaying life and damaging the surgery in medical care, and the steel furnace in production affects the affairs of the party, government and military affairs. In terms of personal future, the leaders of the Ministry of Electricity must also be promoted, right? There have been several large-scale power outages in the past year, and will he still be confused?

Therefore, things that are hindered from the leadership's future and face must be a big deal.

The power system is safety first, just like Niu Dameng grabs an oil filter and wants to punish the person in charge, the leaders in the department will definitely try their best to emphasize this accident.

So, what is the cause of such a major accident?

Answer: Automatic monitoring system failure.

Putting aside the cumbersome terms, it is actually an automation system failure and a software failure.

Zhang Yifu quickly searched his "electronic" computer and quickly learned about the information of Jiutan Power Plant. This is the first pilot power plant in the country to popularize automation. Almost all data and parameters are processed by the computer automatic monitoring system. The system calculates by receiving measurement signals such as generator sets, switching equipment, current and voltage, and comprehensive scheduling instructions. It has the function of automatically adjusting power generation. At the same time, a series of control operations including "grid connection" and "uninterruption" of generator sets are also completed through this system.

Late at night on May 15, the software of this computer system was in trouble. Because there was a connection between the computer system for automation monitoring and the computer system for administrative offices of the power plant, the information was repeatedly circulated back and forth, filling the receiving buffer, resulting in the crash of the automated computer system. The principle is similar to the meaning of "violent hackers" poking the White House website and causing the crash. However, the power plant monitoring system is much more important than the White House. This crash, there is no power generation instructions, and the entire factory will be clicked.

Fortunately, this "click" is aimed at the switch, not the human head. The staff of Jiutan Power Plant and South China Power Grid quickly investigated the accident, handled it manually within half an hour, and resumed production without causing much social impact.

The luck this time is really good. There has been no evening golden dramas and talent shows in 1990. Now everyone has already washed up and went to bed. If there were thousands of girls watching the TV on TV after 20 years, there would be a sudden power outage! The complaint must be unlucky, and then the boss of this power plant will be dead!

The social influence has been extinguished. We cannot fool things within us. We must deal with it seriously. After a week of research and analysis, the department formed an accident investigation expert team and published this accident report and informed it to various units and power plants across the country. It is a warning. As for the degree of accountability of the relevant responsible persons, it has not yet been determined. The factory director of Jiutan is disgusting for at least one year.

"Mr. Duan, I've finished reading it." Zhang Yifu closed the materials and nodded in Duan Youwei.

Seeing that Zhang Yifu saw so quickly, Duan Youwei was afraid that he would not understand the content of the power grid thoroughly, so he asked: "Do you understand these things involved in the power grid?"

After all, power systems are a very specialized discipline, and there are many subdivided directions.

The power plant mainly consists of boilers, steam engines, power generation parts, and the power grid is about power transmission and distribution management such as lines, switches, transformers, etc. In addition, there are specialized directions such as relay protection and automation, which is obviously a bit too much for a 22-year-old undergraduate to get a little bit of a problem.

Zhang Yifu can only be an excessive person.

"I understand it basically." He nodded and said, "There is no way, this is an inevitable accident."

"Is it difficult to avoid?" Duan Youwei couldn't help but raise his eyebrows.

"It can certainly be avoided in theory. If the power plant monitoring system is isolated from MIS, it should not cause such a serious crash. If the switching state quantity is introduced, there is also a possibility of avoiding it. In addition, it is human factors. Of course, this will not happen if manual operation is done. But we always have to popularize automation. This process will always have to pay tuition fees and constantly polish it to ultimately perfect."

After hearing this, Duan Youwei revealed the confusion that only he had when he was a teenager.

This pile of things is simply...it's simply...it's just a fucking confusion!

He has heard of MIS. It is a system that manages factory office information and is only piloted in a few power plants across the country.

He also knows that there are only two values, 0 is off and 1 is on.

But once these two things are combined with the power plant monitoring system, Duan Youwei is completely confused.

In fact, this principle is not complicated. The so-called isolating MIS is equivalent to setting up a firewall to prevent congested information from pouring in and avoiding crashes from the source; and the so-called introduction of the status amount is to bypass the monitoring system and directly allow the actual equipment to obtain the switch, so that the operation will not be missed due to the paralysis of the monitoring system, and accidents can also be avoided.

If you don’t understand these, you can’t blame Duan Youwei. After all, his major is not automation in the design and construction of power plants. The software piloted by Jiutan Power Plant was introduced from the United States. At this moment, few people in China can understand it.

He asked Zhang Yifu to communicate, actually trying to discuss the handling measures after the accident and analyze and investigate matters, but he didn't expect that Zhang Yifu directly proposed two methods to avoid accidents. The most annoying thing is that before proposing these two methods, he specifically said "inevitably".

This made Duan Youwei not know how to answer the conversation.
