What should we do when there is a large-scale power outage? [Copy link]

 

At the beginning of this year, a large-scale power failure occurred in Texas, and large areas of the country were hit by a power outage.

Nowadays, human life is very dependent on electricity, whether it is daily work, entertainment, life, and every aspect. So what should we do if there is a power outage one day? Will it be a disaster?

It's time to make a complete backup plan for our electricity consumption.

How do you think we should deal with it? ? What do you do when there is a power outage? ?

I just saw a related news:

Intel Technologies Drive Energy Network Transformation to Address Climate Change Challenges

You can also learn about it. Guan Guan roughly summarized the following two points

1. Increase the use of renewable energy: including the creation of clean energy and the flexible application of smart grids

2. Deploy and apply smart energy, apply artificial intelligence and Internet of Things technologies to existing systems, and thus form a "flat grid". No matter where you are in the grid, you can use the market to determine the highest and best energy source. The flat grid can use 100% clean, renewable and intermittent energy and enter the real-time energy market.

What do you think about this? ? ?

Large-scale power outages need to consider what electricity is more important, but now there is no classification, so it is difficult to fight for the following classification in different areas, supply different electricity.

1. Electricity for lighting: Candles can be used

2. Electricity for heating, firewood can be burned

3. Water and electricity supply, essential

4. Electricity for cooking

5. Emergency contact electricity, telephone

6. Internet access and electricity consumption

"What if one day the power goes out? ?"

no way.

1. Popularize solar power generation (grid-connected) + appropriate storage at each end-user (enterprises, institutions and even individual homes). When there is excess power generation, it can be uploaded to realize a distributed system and decentralization (commonly known as baldness ) to reduce the risk of a single failure affecting a large area.

2. We are committed to promoting high efficiency and low power consumption of various electrical appliances to reduce the burden on terminal power generation equipment and help realize the distributed system for all people.

A large-scale power grid failure is catastrophic. It is difficult to survive in the city. The best way is to go to the countryside.

Below I list the impacts of a city power outage.

1. When there is no electricity in the city, almost all transportation will be affected, including airplanes, high-speed trains, railways, subways, and buses (all of which are now powered by new energy batteries).

2. There are no traffic lights and no mobile phone communication, so there will be huge traffic jams on city roads. Then you can't leave the city by driving an ordinary car.

3. There was no electricity, no lighting, no water, and I couldn't go to the toilet in two days. There was no signal on my cell phone, so I couldn't call the police or ask for help.

At this time, a motorcycle with a fuel drum is the best means of transportation. Go to the countryside, as long as you have water, firewood, rice and vegetables, you will not starve to death. Wait for the power to be restored. For backup power, I recommend solar panels + intercom + rechargeable batteries + flashlight + radio.

　　At around 17:18 on January 19, 1996, a crane operated illegally by Shougang Company caused the generator set of Beijing No. 2 Thermal Power Plant to shut down, and the local power grid connected to 18 substations collapsed.
　　That night, Xinhua News Agency broadcast the news to the world: a large-scale power outage occurred in western Beijing. The accident caused relatively serious consequences: the computer networks of the State Planning Commission, the Ministry of Finance, the National Information Center, and the Industrial and Commercial Bank of China stopped operating for a time. Some programs of the Central People's Broadcasting Station and Beijing People's Broadcasting Station were suspended; the subway was paralyzed, and the four subway trains parked in the tunnel had more than 2,000 passengers. The tram stopped on the road, and the elevator stopped halfway; the equipment of many hospitals such as Fuwai Hospital, Fuxing Hospital, and Children's Hospital stopped working; Fuxing Commercial City , Xidan Shopping Mall , Chang'an Shopping Mall, etc. urgently evacuated customers; from the Shougang compound in Shijingshan in the west to Qiansanmen in the east, including Xidan, Fuxingmen, Gongzhufen and other large areas were shrouded in darkness; due to the shutdown of the No. 2 Thermal Power Plant, more than 3 million square meters of heating area stopped heating.
　　The large-scale power outage caused by the "1.19" accident was disastrous for large cities and caused huge losses.
　　When the "1.19" power outage occurred, the Beijing Municipal Government took emergency measures, and the public security, subway, hospital, bus, shopping mall and other systems took emergency actions. The power outage did not cause social shocks, no riots occurred, and no one died. The citizens of Beijing showed good quality and self-control. After emergency repairs by the power department, power supply was restored to all power outage areas two hours later.
　　However, this sudden accident also exposed many problems. The generator of a hospital had not been maintained for a long time and was not started until more than 20 minutes later. A sightseeing elevator was forced to stop between 233 meters and 245 meters because they had no backup power supply.

During the several hours of power outage during the accident on January 19, 1996, the Central Military Commission also experienced a power outage.

Power was restored to most areas of Beijing within hours, but Beijing No. 2 Thermal Power Plant was unable to resume normal operation for several days. As a result, heating stopped in millions of square meters and pipes were frozen and cracked.

daemondong posted on 2021-8-24 09:13 What needs to be considered in case of large-scale power outages is what is more important for electricity use, but now there is no classification, so it is difficult. The following classification is different in different regions and different electricity supply...

I think what you said is really good. However, at present, household electricity is simply introduced and then used by each household. If you want to achieve grading, the circuit must be greatly modified.

Appropriate storage? Does it mean that we can store the electricity we use at home? It seems that it is not easy to do this under the current situation.

You must have a radio at home that can be used in an emergency. A small radio that can receive FM and AM will do. It doesn't need to be large or advanced. It's best to use No. 5 batteries. For example, in the special case of a total power outage, you can listen to national instructions and local disaster situations.

I don't have this one, but after hearing what you said, I think I should buy one. It instantly reminded me of a disaster movie...

Yes, and there must be storage (such as batteries, supercapacitors), otherwise it will not be possible to store electricity during the day and use it at night.

This has been achieved many years ago, but the cost is not cost-effective compared with the mains electricity. However, it makes sense from the perspective of "preventing power outages".

Power outages in winter are the most troublesome thing. Now many places have switched from coal to electricity.

In 2008, the snowstorm in South China caused the power systems of several provinces to collapse, railways to be interrupted, hundreds of thousands of people to be stranded at Guangzhou Station, and the coal supply to power plants in the south was insufficient, so they had to transfer diesel locomotives from North China and bring fuel to the south for support. You may want to search "2008 snowstorm" on Baidu to experience the dilemma at that time.

After the accident on January 19, 1996, the State Council ordered the administrative and technical leaders of all units in the Beijing power system to hold a meeting to find out who was responsible. The public security officers were waiting outside the meeting room with handcuffs: "The public security officers don't know who is responsible. Find the responsible person and we will handcuff him immediately." The administrative and technical leaders of each unit argued fiercely at the meeting, and several chief engineers had heart attacks and were carried out of the meeting room and sent to the hospital by ambulance.

In the end, the police only arrested two people from Shougang: one was the crane driver and the other was the driver's assistant.

Now many places are rethinking high-rise residential buildings and restricting their construction.

When there is a power outage due to one of the reasons, such as a large-scale power outage, a long-term power outage, or a catastrophic power outage, there are many disadvantages.

okhxyyo posted on 2021-8-24 11:04 Can you tell me more about it? I only know that there is a kind of home generator.

There isn’t much to brag about, as almost everything is available for purchase: solar panels, DC/DC converters (with MPPT function), and batteries (an ordinary car battery will do).

You may need to make the switching circuit yourself. The structure is not complicated, but you must pay attention to the fact that it must be able to handle a current of at least tens of A.

To power ordinary household appliances, you need to connect an inverter to output AC power.

If you want to connect to the grid to transmit electricity, it will be more troublesome and you have to consider the grid-connected circuit.
