Great Power Technology

The layout of new energy, especially the photovoltaic industry, is a big chess game. The chess pieces have already been placed at key positions, and now, with the high-density battery as the killer piece, the whole chess game will follow. Be active.

In the far northwest, north of the Kunlun Mountains, is the Talatan Photovoltaic Power Station.

This is the world's largest photovoltaic power station, covering an area of ​​more than 600 square kilometers, with more than 10,000 effective solar panels and an annual power generation of 80 million kilowatt hours. In addition to meeting the power demand in Ching Hai Province, excess electricity is also transported across thousands of miles. to the northern Jiangsu region.

Today, this power station welcomed a new batch of guests.

It was a large fleet of dozens of heavy-duty trucks, and the cabins of these trucks contained the energy storage inverters that were to be replaced as a whole.

The commander-in-chief and rear guard of the convoy is called Xu Shengtian. He is a native of Qinghai. From the time this batch of goods entered Qinghai by train, he has been responsible for the organization and dispatch of the entire transport convoy. After a day and night of driving, , and finally arrived at this photovoltaic power generation base.

After getting out of the car, the first thing the bearded Xu Shengtian did was to drive away the sheep at his feet, and then shouted at the top of his lungs to the shepherd not far away:

"Old Li Tou! Old Li Tou! Drive your sheep away quickly! We are about to unload the goods. Let's go to the village and call some strong laborers to help!"

Old Li Tou at the other end heard his shout, ran over with a jolt, smiled, handed over the cigarette, and then asked:

"What kind of new equipment is this time? Why do you want to blast the sheep? I haven't finished eating the grass yet. It's time for the little comrades in the power station to criticize me again."

In recent years, because the solar panels of the photovoltaic power station have blocked a large amount of sunlight, weeds have grown under the solar panels, posing a serious fire hazard. Therefore, the power station simply invited herdsmen from surrounding villages to come over to herd sheep and rely on the sheep. Eat all the grass.

But what is frustrating is that the villages near this huge photovoltaic power station are not large in size, and there are not many sheep. The grass grows faster than the sheep eat, so the staff of the power station give endless instructions every time. Herdsmen must watch the sheep eat up a piece of grass, otherwise if the grass roots are left, they will grow back soon.

Hearing what Old Li Tou said, Xu Shengtian waved his hand and drove away the sheep that gathered around him, and then replied:

"New equipment is new equipment. I don't understand. I'm just a salesman. Hurry up and get rid of the sheep. The power station will be renovated today. You sheep are too much trouble here. Come back tomorrow after the replacement is completed. .”

"Hurry up and call someone. Look, how long can we unload this large amount of cars by ourselves? The engineering team hasn't arrived yet. We can do whatever we can."

"Okay, okay, I'll go right away. You can go and do your work."

As he spoke, Old Li turned around and left, while Xu Shengtian also walked toward the back of the car, and together with the power plant staff who came to greet him, he planned to complete the acceptance and unloading as soon as possible.

After all, he also knew that the power station was very tight on time, otherwise he would not have needed to personally escort such a large batch of goods over day and night.

On the other side, in the conference room of the power plant building, several core leaders were discussing the upcoming large-scale inverter replacement.

".So the current situation is like this. If we follow the normal schedule, it will take at least a month for us to complete the inverter replacement of all 10,000 solar panels."

"But now the superiors have assigned a professional delivery team, with a total of 200 people. Based on the basic working hours, each person can install about 4 to 5 inverters per day. If we extend the working hours a little, we can do it within a week. After completing all the changes, we can basically meet the time requirements set by our superiors."

The young man sitting opposite him shook his head and denied:

"No, it can't be achieved. It will take a week to change the equipment. What about our subsequent debugging? If an abnormality is found during debugging, a comprehensive overhaul and reinstallation will be carried out. This will take at least three days."

"After these three days, there will be power flow tests before grid connection, circuit protection tests, and various emergency off-grid tests. It will take at least a week to complete all these tests."

"Furthermore, these 3+7 days of testing time cannot be saved, as this involves the operational safety of the entire power grid."

"Calculated based on this time, it actually takes us a total of close to 20 days - you still have to consider unforeseen circumstances and leave enough margin."

"Twenty days is five days longer than the 15-day target given to us by our superiors."

"This five-day delay will have a huge impact on the overall plan, and we cannot afford the risk."

After listening to his words, everyone in the conference room nodded in agreement.

"What you said is indeed correct, but the problem is that we really don't have a good solution - I can compress it for you during the installation stage. Considering the full workload and the training of old people and new people, the most I can do is Compressed to 4 days.”

"However, this is still two days short of our goal. Where can we squeeze out these two days? We really can't squeeze out the dressing process."

The young man looked at the speaker's tired face, sighed and said:

"Brother Liu, I know you really have nothing to do, but the more helpless you are, the more we have to find a solution. I want to confirm with you, is the replacement process of energy storage inverter complicated?"

After pondering for a moment, the man named Brother Liu replied:

"It's not complicated to say it's complicated, but if you want to recruit a group of completely inexperienced workers, it's completely unnecessary. Firstly, the efficiency improvement will not be much. Secondly, the safety is too poor. If something goes wrong, If there is any problem, it will slow down our overall progress, and I won’t agree to it.”

The young man nodded and said calmly:

"I know what you mean, but what I want is not to introduce new people. Just like what you said, this plan is too unreliable."

"What I am thinking is, if the inverter replacement process is not complicated, is it possible for us to disassemble the steps and change the single-person single-board operation method into an assembly line operation?"

"As you know, our operation interface is relatively neat and unified. If a group of 10 people are responsible for an area and each person only does one step, the speed should be much faster."

Hearing the young man's words, the man was stunned for a moment. After thinking for a moment, he replied:

"Yes, this plan is very feasible. The delivery team we have are all experienced workers. They are familiar with every process. If we make a list and let each of them be responsible for only one or two processes, it can indeed form a The effect of assembly line work.”

"But the problem is, I don't know how effective this method is in practice - this method of operation has not been tested anywhere else, and there are certain risks."

The young man silently recorded the key points of the meeting on paper, and then replied without looking up:

"There will definitely be risks, so we will take half a day to test first. If the effect is good, we will continue to implement it in this way. Of course, if the effect is not good, I will find ways to save time in terms of testing."

"The 10-day test time, if related projects are jointly tested, I estimate can be compressed to within 8 days. Once all unexpected situations are eliminated, we should be able to complete the grid connection before July 3."

"Are you sure there's no problem?"

"I am not sure."

The young man shook his head and then continued:

"However, we have to give it a try. At the same time, we must also monitor the progress in real time. Once we find that the progress is slower than expected, we must report it immediately and adjust the strategy uniformly to avoid our problems affecting the overall layout."

"Now, everyone should go to their places. Time waits for no one, so let's not waste any more meetings."

After saying that, the young man stood up and left first. After opening the door, the dazzling sunlight reflected from the solar panel array area, throwing his figure into a dazzling light.

Beside him, herders, villagers, students on vacation, teachers from rural primary schools, and power station staff in different costumes gathered near the heavy truck and began the intense but orderly unloading work.

In the past ten years, it is this group of people who have held up the sky that is about to collapse in China's photovoltaic industry.

Today, they will wield the invisible shovel in their hands and lay the last shovel for the fossil energy industry under Western hegemony!
