The construction of the Tree House Guest House is proceeding in an orderly manner under the arrangement of Wang Wenlin and others, and according to the workload, it will take about half a year.

After Wei Minsheng was idle, he thought carefully about the energy structure of the entire villa and found that there were still some problems to be dealt with.

First, the rated output power of the gas generator is 60 KW, but the band saw machine and woodworking power tools together, that is, plus the ten chainsaws purchased later, the power used at the same time is less than 40 KW, and the remaining 20 KW is wasted.

Second, in other places where electricity is used, the power supply has been relatively tight, and due to the limitation of power resources, many convenient electrical appliances cannot be used.

Third, after the construction of the guest house, there will suddenly be a large increase in electricity demand, and the electricity generated by the two fans and solar panels alone is far from enough.

Fourth, the long-distance transmission of electricity, for the voltage of 220V, if the transmission distance is more than one kilometer, excluding the loss of the line, there may be less than 100V voltage.

Fifth, the power in the power generation base needs to be sent out in the future, so the voltage can only be raised to 10KV through the transformer, and then transmitted to the nearby power point, and the transformer is used after the voltage is reduced, after all, the best transmission distance of the 10KV line is also about 15 kilometers.

These problems in the real world are all solved by the State Grid, and there is no need for ordinary people to consider them. But in this other world, where can Wei Minsheng go to find the State Grid, he can only build it slowly.

Those stories that cross a wire connecting thousands of miles in the text, just listen to it after dinner, and people with a little knowledge of electricity will take it as a joke.

Fortunately, there is a twenty-four-fold time difference between the two worlds, otherwise this power grid will not be completed until Wei Minsheng dies of old age.

Wei Minsheng believes that the main problem at present is to transfer the wasted 20 KW of electricity resources to the power consumption points of the courtyard, the teaching area and the guest house, so as to ensure that the transmission capacity of the power grid will not be limited for at least five years.

Wei Minsheng has not considered distributing gas generator sets to these power points, but first, the noise problem is difficult to solve, and second, there is no suitable operation and management personnel, after all, whether the main component is carbon monoxide gasified gas or high-pressure electricity is a potentially fatal thing.

Only after the completion of the transmission network can the installed capacity of the power generation base be increased, otherwise it will be a waste if there is more electricity generated.

There is another reason why Wei Minsheng chose to use the 10KV transmission network, that is, ordinary cement poles can be used, as long as the safety distance of 6 meters under the line is guaranteed. Moreover, a 10KV to 220V or 380V transformer is easy to buy, which requires less investment and simpler equipment than other high-voltage transmission methods.

Now only Wei Minsheng, Wang Wu'an and Wang Wujia have some knowledge of electricity in the villa, but fortunately, Wei Minsheng can obtain the construction design drawings of various power transmission projects from the network in the real world.

After all, this power transmission network cannot be completed in a few days, so Liu Mengling and her sisters can have more time to purchase relevant equipment.

The excavator has played a great role in the work of standing the cement pole, and the position of each cement pole has been determined according to the actual situation of the single rod span and the terrain on the line design diagram.

The front is dug by hand, and the cement rod connected with bolts is hoisted up by the excavator in the back, and the verticality is detected with a conical line hammer, and after simple fixing with a small stone, it is solidified with a concrete seat, and finally it is necessary to detect whether the cement rod is kept in the vertical direction again.

Due to the fact that there are many restrictions in the real world in the other world, and the materials and labor are guaranteed, it only took ten days to install all the cement poles connecting several power consumption points from the power generation base to the farthest valley.

When the cement pole was installed in the teaching area, the excavator hoisted the tall cement pole left an indelible image in the hearts of those students. This Huaxia Villa is too powerful, not to mention how such a heavy and high stone pole is made, even if a few people erect this stone pole, it is not something that people outside can do.

When the cement had not yet reached its highest strength, Wang Wu'an and Wang Wujia led a few villagers to install the crossbars and insulated porcelain bottles on the telephone poles to prepare for the future wiring.

After installing the crossbar and porcelain bottle, Wei Minsheng took Wang Wu'an and Wang Wujia to repair the places where the transformers were placed at each power point, of course, the necessary lightning protection measures were still needed.

After all the facilities were ready, the equipment such as aluminum wires and transformers were also in place, and it took a few more days to finally complete the simplest transmission network.

Thinking about the hardships of this period of time, Wei Minsheng didn't believe that those traversers could build a world power without the support of modern resources, just by relying on those superficial common sense in their memory.

After the completion of the transmission network, in order to prevent excessive power consumption, the output power of the generator set will be exceeded, causing damage to the power generation equipment. Wei Minsheng selected a villager as the power dispatcher at each power point, and numbered the transformers at each power point.

Because the current power consumption of each power point is not very large, there used to be UPS backup power supply, so if the backup power of the power point is insufficient, when it needs to be charged, use the walkie-talkie to contact Wang Wuan or Wang Wujia, when the output power has a balance, Wang Wuan and Wang Wujia use the walkie-talkie to schedule the excess power.

For example, after the No. 1 power point is closed, there is still power left, so you can continue to close the No. 2 power point. If several power consumption points are in the peak period, you can also temporarily stop the work of the woodworking processing plant to fully protect the electricity consumption in other places.

With this primary high-voltage transmission network, the wind, thermal and solar power resources in the villa can be fully utilized. Even if more wind turbines and more solar cells are available in the future, the power generated can be fully utilized by this transmission line and the distributed storage network at each power consumption point, avoiding the waste of energy.

Even if each waterwheel only has a power generation capacity of 3 KW, but ten waterwheels also have 30 KW, and it is a clean energy that almost does not require many people to manage, and it can work 24 hours a day, and it can generate at least more than 700 kWh of electricity a day.

By connecting hydropower to the transmission grid, there is another stable source of electricity supply in the lodge.

Since this artificial waterway does not block the flow of water, it will not affect the survival of fish in the river, and Wei Minsheng feels a little painful in his heart when he thinks of the disappearance of wild Chinese sturgeons in the world because of the existence of dams.

I am also making use of the abundant forest resources here, but after using them, I will plant other trees, which can be considered sustainable.

Development must not come at the expense of the environment. Wei Minsheng hopes that there will always be white clouds, blue skies and green water and clear mountains here.
