Through big data analysis and intelligent diagnosis, the automatic monitoring and early warning of the limited power status of the photovoltaic system have been realized. The application of this technology can effectively improve the performance indicators and operation and maintenance efficiency of photovoltaic systems, and provide good technical support for the sustainable development of the photovoltaic industry.
The reason for the old power limit of the inverter The power limit of the inverter caused by the high internal temperature. Due to the low voltage of the power grid, the low-voltage crossing function is triggered, resulting in the limited power operation. The inverter application scenario is wrong, resulting in the self-drop operation. The third-party data issued a power limit instruction, resulting in the power limit operation of the inverter.
Current limit: that is, limit the current ampere, and jump when it reaches a certain value, but from your description, it is not like.
The Northeast power restriction will have some different impacts on different industries. This impact will still cause certain fluctuations in the development of China's economy. As for the upward or downward fluctuations, it depends on the subsequent development. Why pull the gate to limit electricity? The instruction of pulling the gate to limit electricity is beneficial to the energy sector.
First of all, let's look at the temperature. Since December, the temperature in Hunan and Jiangxi has been extremely low due to the influence of strong cold air. Especially in Hunan, the whole province will enter winter one month earlier than in previous years this year. And the north of heating and centralized heating in these areas is different, which is dominated by electricity.
At the same time, most regions have also put forward restrictions on electricity use for factories in relevant areas, requiring factories to use electricity reasonably, and formulating relevant electricity use plans.
Why is the power restriction notice issued? These cities will be restricted from electricity, mainly to save energy and reduce emissions. As an active practitioner of the Paris Climate Agreement, China requires China to reduce domestic carbon dioxide emissions by 65% by 2030 compared with 2005.
1. After all, the college dormitory is not their own home, and the population of the dormitory is also relatively dense, so the school's electricity restriction is also for the safety of our students. Every year, there are fires in colleges and universities that do not pay attention to electricity safety, and the impact of fires in the dormitory is very serious, so there is no Anyway, we should still focus on safety.
2. In students' daily life, they often secretly use high-power electrical appliances in the dormitory, which seriously affects the safety of electricity in the dormitory. In recent years, there have been many fires caused by high-power electrical appliances in the dormitory. So there is a restriction on the use of high-power electrical appliances in student dormitories, which has become the focus of the new college dormitory.
3. The intelligent power limit of Shandong Agricultural University is basically 200w to 300w per person, and the power limit is different for different dormitory buildings.The power limit in the dormitory of the school headquarters is 300w per person, and the power is limited at night in summer. What electrical appliances can be used after installing the intelligent power limitation system: all safety appliances can be used normally.
4. First of all, college students are in college, the so-called blooming period, when they are exposed to the Internet and know the world without leaving home. If the power is limited, it will be a blind man touching an elephant, which is unimaginable. Secondly, the function of electricity is not only reflected in the outside world within reach, but also gives college students the opportunity to innovate.
5. This is the power factor set. If the light is turned on, the power factor will change. It's just that there is a general power switch on each floor of the dormitory, and then it is divided into all the way to send electricity to each room. There is a power distribution box all the way. There is a row of small single air switches inside. Just choose the switch to 2a.
If you want to limit the power, you can use some smaller power, or you can buy a voltage regulator. Generally speaking, you can use high power after using the transformer. There are also special circumstances when the school's power limit is too strong, the voltage regulator is useless. Don't ask me why I know so much, because I The school is also limited in electricity.
Just buy a good quality voltage regulation. It is very easy to use. Without turning on the electrical switch, plug it in, turn the knob to 0, then turn on the switch, slowly turn it in the direction of 10, and do not turn it when the electrical appliance starts to work (below 2500W is fine).
As long as the phase shift device (capacitor, diode, controllable silicon voltage regulation, etc.) is added, the intelligent power limitation system of the university dormitory can be completely cracked and the illegal electrical appliances can be used at will. However, the intelligent power-limiting module (DK-20 series) produced by Yijia Technology cannot be cracked. It can identify illegal electrical appliances and phase shift devices. It is safe and reliable, low power consumption and long life.
W's clipboard is rumored to be an intelligent power-off system that can identify whether it is a heating appliance. The alien computer in our dormitory measured that the CPU accounted for more than 50W, and the graphics card was close to 300W, plus other internal power and loss. The battery just arrived yesterday. Stay! Give up! Limited! Electricity! They are all illegal electrical appliances, and we must cooperate with the school's management.
Yes, Yes, Yes, Our Dormitory Is Limited To Electricity, And We Can Only Charge Mobile Phones. OnceThe computer and the mobile phone power bank are charged together, and the power used exceeds the specified range, so the power is cut off for us.
Second, the fundamental way to really solve the safety of electricity is not to limit electricity. The relationship between logistics groups, dormitories and students is essentially the relationship between property companies, residential areas and residents. Most of China's fires caused by electricity occur in residential areas.
