At 9 p.m. on March 4, at the last moment of the emergency repair project for the Shuweih power plant and the desalination plant, the dispatch center of the Kuwait National Power Company was brightly lit and full of tension. Kuwaiti, Saudi, Chinese and German electrical engineers all walked in a hurry, with serious expressions.

The tall and sturdy Elbulda closed two thin lips, crossed his arms and pondered something, looked at the watch on his wrist from time to time, and paced back and forth in front of the large screen with the simulation function.

As the chief engineer of the emergency repair project, he is very confident in the Schweich power plant and the medium and high voltage lines in the main urban area. The reason for this tension is entirely due to the temporary addition of the grid automation system on the third day of the intensive repair project.

In order to achieve the ultimate goal of remote signaling, remote control, and telemetry, a self-supporting optical cable and spread-spectrum radio station worth nearly $4 million were even pulled from the Saudi National Power Company's material warehouse to form an electric power communication network.

The NB electrical automation system has only been tested at the Berlin waste incineration power plant, and has not even been officially put into use, so it is undoubtedly very risky to apply such an immature technology to the big network.

At 9:20, one after another, under the escort of heavily loaded soldiers, one after another bulletproof luxury cars came to the dispatch center building, which was not seriously damaged.

The first to get off the bus was Kuwaiti Deputy Prime Minister Al-Sabah, followed by Faisal, chairman of the Kuwait National Electricity Company. Then there is the chairman of the Saudi National Power Company, Abdul Ahmad. Aziz and Prince Metbu, the real big boss of the repair works.

The Deputy Director of the Kuwaiti Reconstruction Commission, Al-Faisal, the nominal general contractor, Mohammed, and representatives of the Kuwaiti military and journalists from various countries came...... The hall was packed. It was not until the Kuwait National Electricity Company invited the reporter to the reception room. The dignitaries, accompanied by Chairman Faisal, walked into the dispatch center.

Such an important occasion. Naturally, the charter cannot be absent.

But the protagonist is not him, but Muhammad, who has spent two days making up for this moment.

"Distinguished Mr. Deputy Prime Minister, Chairman Faisal, Chairman Abdul, Distinguished Reconstruction Committee officials, first of all, on behalf of all colleagues and partners of Mohammed Power Installation Company, NB Electric, please allow me to announce the good news that six 120 MW generating units of the Schweich Power Plant were officially idled and supplied with heat to the Schweich desalination plant thirteen hours ago. By the end of the hour, 3,450 tons of seawater had been desalinated. ”

This was undoubtedly a miracle in the history of engineering, and Deputy Prime Minister Al-Sabah was the first to stand up and give him a heartfelt round of applause. There was thunder in the dispatch center for a while, and it couldn't be calmed down for a long time.

"Thank you, thank you very much."

Muhammad grabbed the corners of his white robe, bowed slightly, and continued in a frustrated voice: "Everyone can see that the Schweich power plant with a total installed capacity of 720 megawatts has not been connected to the grid, but the important facilities have been lit up for the past few days. For this. Our company and our company's closest partner NB Electric, as well as China's power company have invested a lot of manpower and material resources.

Temporary power supply for a single engine from the first day of the emergency repair project. By 4:20 a.m. on the third day, when multiple diesel generator sets were connected to the power supply, we overcame one difficulty after another. In order to increase the power supply capacity and not affect the normal operation of important facilities, we had to temporarily set up six power stations.

In order to ensure that the instantaneous voltage, frequency and phase of the 389 diesel generator sets of our company, NB Electric and our power company are the same when generating electricity, thousands of engineers and technicians have made great efforts. In 15 minutes, we will face the last and most serious challenge, which is to get the Schweich power plant officially connected to the grid! ”

He is not deliberately exaggerating the difficulty of grid connection, and Faisal, chairman of the Kuwait National Power Company, agrees, and explains sideways: "Under normal circumstances, grid connection must go through three stages of experimental tests of no-load, load-bearing and 168-hour full-load operation before it can generate electricity normally, and we obviously don't have that much time."

In addition, the demand for electricity in the city is so great that the six temporary power stations cannot stop generating electricity until several other power plants are restored. This means that the multiple generators will be connected to the grid at the same time as the six large generator sets at the Schweich power plant. In particular, a change in the voltage of any one of the generators of a temporary power station may cause a change in the grid voltage......"

Both hardware and software must be hard, and the real technical work is done.

Deputy Prime Minister Al-Sabah was worried, and couldn't help but look at the young Hong Kong engineer behind him, nodded slightly, and showed a knowing smile, wanting to tell him that everything was normal, and there would be no problems with the next grid connection.

At this time, the intercom of the chief engineer of Alberta came from the front report one after another: "The dispatching center, the dispatching center, the power plant booster station has been inspected, and the power plant booster station has been inspected!" ”

"Dispatching center, dispatching center, the high-voltage side of substation No. 1 is disconnected, and the high-voltage side of substation No. 1 is disconnected."

"Dispatch center, the high-voltage side of substation No. 2 is disconnected."

"The dispatch center, the switch station is all right, the switch station is all right."

"Dispatch center, No. 1 repair team in place."

"I am the dispatching center," the chief engineer of Alberta grabbed the walkie-talkie and called out with a stern expression in fluent English: "Attention to the power plant, water plant, stations and repair teams, I am the dispatching center, and now I have entered the countdown to grid connection, please strictly abide by the operating procedures, and close the circuit according to the original plan to ensure the safety ......of the power grid in the main urban area."

The equipment has been tested, but no one can guarantee that there will be no problems until it is officially put into operation.

It is not easy to set up a power grid in the main urban area, and the progress cannot be wasted because of this. Therefore, each substation must be disconnected from the 132 thousand volt high-voltage line, until it is confirmed that the output voltage is stable and the high-voltage line is fine, and then it will be closed and energized one by one.

Real equipment is easy to charge for, but automatic control systems are not so easy to price.

Not wanting to miss this once-in-a-lifetime opportunity, Muhammad moved on to explain: "Gentlemen, I believe you have noticed that Chief Engineer Eburda is using walkie-talkies for dispatch and command. Ten minutes later, another miracle of the emergency repair project, the NB grid automation control system, will be officially put into use. Replace this most primitive and backward command and dispatch method.

NB Electric's microcomputer relay protection technology and reliable products. As well as our company's excellent installation and commissioning capabilities. It will provide modern equipment monitoring and control management and remote online monitoring for the Kuwait power grid to ensure a stable and reliable supply of the power system, as well as an optimized, flexible and diverse power load management structure.

The large screen behind me has a reliable management system simulation and simulation function, from which you can intuitively monitor the operation of the power grid. Through this series of automatic control devices on my left, I can remotely control terminals such as power plant booster stations, switch stations and substations, and implement intelligent load offloading, generator output sharing, medium and low voltage automatic power switching, medium voltage circuit fault location, isolation and network reconstruction, power monitoring and shunt metering, real-time primary equipment detection and maintenance management, alarm and event management and other operations......"

Third-rate enterprises make products, and second-rate enterprises do brands. First-class enterprises do standards.

In such a short period of time, the installation of a set of immature power grid automation control system is to take advantage of this opportunity to set up the next large-scale power grid reconstruction standard.

For the sake of business, for the sake of performance, it is also worth taking a little risk.

If something goes wrong, I'm afraid that I can't solve it.

In order to ensure that nothing goes wrong, almost all the engineers from NB Electrical Automation Control are here. Even the charter went into battle in person, soaked in the communication room for two whole days, and only returned to the nanny ship three hours ago to take a shower and change into clean clothes. And rush back here non-stop to witness this historical moment that can almost affect the development of NB Electric in the next ten years.

The countdown entered the final fifteen seconds, as Chief Engineer Alberta gave the order. Electrical engineers stationed at the Schweich power plant were the first to finally close the circuit breaker at the booster station.

Everyone was sweating, and two minutes later, good news came one after another.

The step-up transformer is operating safely, more than 30 kilometers of 132 thousand volt high-voltage lines are safe, the switch station is normal, the No. 1 132 thousand volt substation is energized, and the No. 1 33 thousand volt substation is energized and operated......

It wasn't until the last 33 kV transformer was put into operation, and until several automated control tests had been done, that the chief engineer of Alberta looked back with relief: "Gentlemen, I think we have succeeded. ”

Warm applause resounded in the dispatch center, and Deputy Prime Minister Al-Sabah and other senior Kuwaiti officials stood up and shook hands with all the staff members one by one to express their heartfelt thanks and congratulations.

Mohammed suppressed the excitement in his heart, clasped the hand of Faisal, chairman of the Kuwait National Electricity Company, and said with a sincere face: "Mr. Chairman, I'm very sorry, this is just a trial operation, and it will take us at least half a month to hand over the power grid to you." ”

Just after the war, there are all kinds of waste waiting to be rebuilt, even if it is taken over now, there are not so many people, not to mention that it is a reflection of responsibility for people to do this, Chairman Faisal agreed without hesitation: "Of course there is no problem, in fact, even if you don't say it, we will make a corresponding request." ”

Saudi National Power Company Chairman Abdullah. Aziz would not miss this once-in-a-lifetime opportunity to immediately pull Deputy Prime Minister Al-Sabah aside and lose no time in discussing the possibility of a high-voltage line to be built by Mohammed to provide electricity to southern Kuwait.

The real boss, Prince Mateb, pulled the officials of the reconstruction committee to negotiate the restoration of the remaining power plants. The Kuwait National Electricity Company's dispatch center suddenly became a place of business, and by the time reporters were invited to visit, orders with a total contract value of up to $1.6 billion had been finalized.

On the way back to the nanny ship, Chen Zhenghuai felt very unbalanced, and sighed and said: "A big order of 1.4 billion US dollars!" The pay and the gain are too unequal, and the Saudi National Power Company provided some construction vehicles and some equipment, and it became the biggest winner. ”

The charter smiled and said casually: "That's where people sell electricity, and besides, we can still get a piece of the pie in the erection of transmission lines." ”

"A lot of money has been made by Saudi Arabia, and you don't feel distressed at all?"

The reconstruction of the two power plants was handed over to the Mohammed Power Installation Company for general contracting, and the grid automation control system was approved by the Kuwait Power Company. (To be continued......)
