Chapter 273 Replace the energy storage inverter and bury the last soil
The layout of new energy, especially the photovoltaic industry, is a big chess game. The chess piece has already been dropped at a key position, and now, with the high-density battery falling, the whole game will follow closely. Be active.

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

This is the largest photovoltaic power station in the world, covering an area of ​​more than 600 square kilometers, with more than 1 effective solar panels and an annual power generation capacity of 8000 million kilowatt-hours. In addition to meeting the electricity demand in Qinghai Province, the excess electricity is also transported across thousands of miles to the northern Jiangsu area.

Today, the power station welcomes a new group of guests.

It was a large fleet of dozens of heavy-duty trucks, and the compartments of these trucks were equipped with energy storage inverters that were to be replaced as a whole this time.

The general commander and escort of the convoy is called Xu Shengtian. He is a native of Qinghai. He has been in charge of the organization and dispatch of the entire convoy since the cargo entered Qinghai by train. After a day and a night of driving , and finally arrived at the photovoltaic power generation base.

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

"Old Litou! Old Litou! Hurry up and blow your sheep away! We are about to unload, go to the village and call some strong laborers to come and help!"

Hearing his shout, the old Li on the other side ran over step by step and handed him a cigarette with a smile, and then asked:
"What new equipment is it this time? Why are you going to blast the sheep? I haven't finished eating the grass yet, and the little comrades in the power station who can't clean it after a while should criticize me again."

In recent years, because the solar panels of the photovoltaic power station have blocked a lot of sunlight, weeds have grown under the solar panels, which has brought serious fire hazards. Therefore, the power station simply invited herdsmen from surrounding villages to herd sheep. Eat up the grass.

But what is frustrating is that the villages near this huge photovoltaic power station are not large, and there are not many sheep. The herdsmen must watch the sheep eat up a piece of grass, otherwise, if the grass roots are left behind, they will grow back in a short time.

Hearing Old Li's words, Xu Shengtian waved away the sheep gathered around him, and then replied:
"New equipment is new equipment. I don't understand. I'm just a hauler. Hurry up and drive the sheep away. The power station is going to be reinstalled today. Your sheep is too much of a hindrance here. Come back after the replacement is over tomorrow." .”

"Hurry up and call someone. Look at this large area of ​​cars. When can we unload them by ourselves? The engineering team hasn't arrived yet. We can do a little bit."

"Alright, alright, I'll go right away, you hurry up and do your work."

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

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

On the other side, in the conference room of the power plant, several core leaders are 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 [-] solar panels."

"But now the superior has dispatched a professional delivery team, with a total of 200 people. Based on the basic working hours, each person can replace 4 to 5 inverters per day. We can extend the working hours a little and we can do it within a week. Complete all the costume changes, which can basically meet the time requirements of our superiors."

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

"No, it can't be achieved. It takes a week to reinstall, so what about our subsequent debugging? If abnormalities are found in the debugging, we need to conduct a comprehensive overhaul and reinstall. This part 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."

"Also, the 3+7 days of testing time cannot be saved, which involves the operation safety of the entire power grid."

"According to this time calculation, in fact, we need to spend a total of nearly 20 days——you have to consider unexpected situations and leave ample margin."

"20 days, compared with the 15-day target given to us by our superiors, 5 full days more."

"This 5-day delay will have a huge impact on the overall plan, and we cannot afford the risk of song."

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

"You're right, but the problem is that we really don't have a good solution—I can compress it for you during the installation phase. Considering the full load of work, plus the old and new training, I can at most Compressed to 4 days."

"However, this is still two days away from our goal. Where do we squeeze out these two days? The dressing session really can't be squeezed out."

Looking at the tired face of the speaker, the young man sighed and said:
"Brother Liu, I know you really can't do anything, but the more we have no way, the more we have to find a way. I want to confirm with you, is the replacement process of the energy storage inverter complicated?"

After pondering for a while, the man named Brother Liu replied:
"It's not complicated, but if you want to recruit a group of completely inexperienced workers to replace them, it is completely unnecessary. First, the efficiency improvement will not be too much. Second, the safety is too poor. In case something goes wrong What kind of problem will slow down our overall progress, I will not agree."

The young man nodded and said in a calm tone:

"I know what you mean, but I don't want to introduce new people. Just like you said, this kind of plan is too unreliable."

"What I think is, if the inverter replacement process is not complicated, is it possible for us to dismantle its steps and change the operation method of a single board into an assembly line operation?"

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

Hearing the young man's words, the man was taken aback for a moment, and after thinking for a moment, he replied:

"Yes, this plan is very feasible. The delivery team in our hands is all experienced workers who are familiar with every process. If a list is made and each of them is only responsible for one or two processes, it can indeed be formed. The effect of pipelining."

"But the problem is, I don't know how effective this method is in practice—this method of operation has never been tested anywhere else, and there are certain risks."

The young man silently recorded the main points of the meeting on paper, and then replied without raising his head:
"There will definitely be risks, so we will take half a day to test it 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 a way to save time from the test."

"The 10-day test time, if the related projects are jointly tested, I estimate that it can be compressed to within 8 days, and after excluding all unexpected situations, we should be able to complete the grid connection before July 7."

"Are you sure there is no problem?"

"I'm not sure."

The young man shook his head, then continued:

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

"Now, everyone take their places, time waits for no one, let's not waste any more meetings."

After all, the young man got up and left first. After opening the door, the dazzling sunlight reflected from the solar panel array area, throwing his figure into the glare.

Beside him, herdsmen, villagers, students on vacation, rural elementary school teachers, and power station staff in different costumes gathered near the heavy trucks, and they had already started the intense but orderly unloading work.

In the past decade or so, it was this group of people who propped up the sky that was about to collapse in China's photovoltaic industry.

And today, they will brandish the invisible shovel in their hands to bury the last bit of soil for the fossil energy industry under Western hegemony!
