After a rough sweep, as soon as several groups of numbers were unfolded, Zhang Yifu figured out the situation.

Jiutan Power Plant, the whole plant unit tripped, load dumping 890,000K, the source of the provincial power grid frequency 5o.o5Hz dropped sharply, resulting in the adjacent frequency modulation power plant tripping load 390,000K, the provincial power grid lost 1.29 million K power, 23% of the power of the whole network, the lowest system frequency dropped to 48.93%.

This series of numbers and terminology is very specialized, and the power grid experts have to understand it for a while, not to mention the people at the power plant, let alone the newcomer Zhang Yifu. But the current situation is-

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

Trouble......

If you throw away the jargon, it's a very simple question.

There was an accident in a power plant, and the units were stopped, which led to problems with the voltage of the entire power grid and the regional power grid, so that the power plant that was specifically responsible for adjustment was forced to make some reactions to recover, and as a result, the guy who saved people also fell into the water, and the province's power grid lost 23% of its electric power, and 1/5 of the province's area fell into darkness.

Thankfully, the darkness lasted less than half an hour, and the problem was quickly solved at the Jiutan Power Plant.

Even so, it was still a very serious accident.

The power accident is not an ordinary industrial accident, not that the equipment is blown up and the equipment is burned, of course, the equipment damage is an accident, but the most serious accident is the power outage for the user, the delay in life is small, the operation in the medical treatment, the steel furnace in production, and the impact on the party, government and military affairs are big. As far as his personal future is concerned, the leader of the Ministry of Electric Power also has to be promoted, right? There have been several large-scale power outages in the past year, and he is still not mixed?

Therefore, it must be a big deal because of the leader's future and face.

Power system, safety first, just like Niu Dameng grabbed an oil purifier to punish the person in charge, the leaders of the ministry will definitely play with their lives to emphasize this accident.

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

Answer: Automatic monitoring system failure.

Cumbersome jargon aside, it's actually automation system failures, software failures.

Zhang Yifu searched for his "electric" brain and quickly learned the information of the Jiutan Power Plant. This is a pilot power plant for the popularization of automation in the whole country, almost a number of qiē and parameters are processed by the computer automatic monitoring system, the system receives the measurement signals of the motor unit, switchgear, current and voltage, etc., and calculates the comprehensive scheduling instructions, with the function of automatic electrical adjustment, and at the same time, a series of control operations including the "grid connection" and "network disconnection" of the motor unit are also completed through this system.

In the middle of the night on May 15, the software of this computer system was buggy, because there was a connection between the special computer system for automatic monitoring and the computer system for the administrative office of the power plant, the information was repeatedly wound back and forth, full of receiving buffers, and the automatic computer system crashed, and the principle was similar to the meaning of the "violent hacker" poking the White House website to cause a crash, but the power plant monitoring system is much more important than the White House.

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

This time the luck is really good, 9o years there is no evening golden drama and talent show, at this time everyone has already washed and slept, if it is placed in 2o years, tens of millions of girls watch the puppet on TV, suddenly the power outage!

After a week of research and analysis, the ministry formed an accident investigation expert group and reported it to all units and power plants across the country.

"Mr. Duan, I'm done. Zhang Yifu closed the material and nodded his head.

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

After all, power system is a very specialized discipline, and there are many subdivisions in it.

The power plant is mainly boilers, steam turbines, and electricity, and the power grid is the transmission and distribution management of lines, switches, transformers, etc., in addition to relay protection, automation and other specialized directions, so that a 22-year-old undergraduate student is obviously a little too much to grasp every problem.

Zhang Yifu can only be an excessive person.

"Basic understanding. He nodded and said, "No way, it's an inevitable accident." ”

"Is it inevitable?" Duan Youwei couldn't help but raise his eyebrows.

"Theoretically, of course, it can be avoided, if the power plant monitoring system is isolated from mIs, it should not be so strict with the crash, and if the switching state amount is introduced, it is also possible to avoid it. In addition, there is the human factor, of course, this kind of thing will not happen if you operate it manually, but we always have to popularize automation, this process will always have to pay tuition, and continuous polishing can finally be perfect. ”

After Duan Youwei heard it, he revealed the confusion that only teenagers can have.

This bunch of stuff, it's just ...... It's ...... It's just fucking confused!

mIs, he has heard, is a system for managing factory office information, and it is only running on a pilot basis in a few power plants across the country.

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

But as soon as these two things were combined with the power plant monitoring system, Duan Youwei was completely confused.

In fact, this principle is not complicated, the so-called mIs isolation, is equivalent to a firewall, do not let the congested information rush in, from the source to avoid crashes, and the so-called introduction of state quantity, is to bypass the monitoring system, directly let the actual equipment get the switch, so that the monitoring system will not be paralyzed and miss the operation, the same can avoid accidents.

If you don't understand this, you can't blame Duan Youwei, after all, his specialty is in the design and construction of power plants, not automation, and the software for the pilot operation of Jiutan Power Plant is imported from the United States, and I am afraid that few people in China can figure it out at this time.

He communicated with Zhang Yifu, in fact, he wanted to discuss the handling measures after the accident and the analysis and investigation, but he didn't want Zhang Yifu to directly put forward two ways to avoid the accident, and the most annoying thing is that before proposing these two methods, he also deliberately said "difficult to avoid".

This made Duan Youwei not know how to answer.

Seeing Lao Duan's confused expression, Zhang Yifu felt that he had accidentally shown off his skills again, a big taboo!
