What does it mean to increase the power distribution capacity of the power system?

Capacity increase refers to the production and operation of the electricity consumer.

In the process, due to the expansion of production capacity demand, the original application for the use of electricity capacity has been unable to meet the needs of production and operation, and must be applied for an increase in capacity on the basis of the original.

If the electricity consumer needs to increase the capacity, it must submit a written application to the legal power supply entity (power supply department), and issue the relevant application materials of the power consumer, which can only be carried out after the power supply party reviews and approves.

Electricity capacity increase means that in the process of production and operation, due to the expansion of production capacity demand, the original application for the use of electricity capacity can no longer meet the current production and operation needs, and must apply for capacity increase on the original basis.

Power capacity increase refers to the fact that in the process of production and operation, due to the expansion of production capacity demand, the original application for the use of electricity capacity (usually calculated according to the capacity of the transformer, the unit is KVA) can no longer meet the needs of production and operation, and must apply for capacity increase on the original basis.

The main structure of the power system consists of a power source, a power network, and a load center. Power supply refers to all kinds of power plants and stations, which convert primary energy into electrical energy; The power network is composed of step-up substations, transmission lines, load center substations, and distribution lines of power sources.

Its function is to boost the electric energy emitted by the power supply to a certain level and then transmit it to the load center substation, and then lower the voltage to a certain level, and then connect with the user through the distribution line.

A user capacity increase is when your original transformer capacity is not enough, and you need to replace a larger transformer or add a transformer. Grid capacity increase refers to the upper-level substation being hung on the grid with a higher voltage level, or replacing the transformer like the user.

Capacity increaseRong is generally said to replace small transformers with large transformers according to load growth.

Because the load increases, the system needs to increase the capacity, that is, the switch, the fixed value, the wire, and the transformer are all increased.

way to develop the power distribution business.

Some people in the industry believe that the main purpose of incremental distribution reform is to break the monopoly, improve services, reduce costs, and innovate in technology. In the process of reform, the biggest benefit is that it is found that the stock distribution assets on the user side are currently free from the power industry management system.

outside. At least twice as much as the power grid assets, precipitating huge assets, ignoring professional management, distorting the market, and constituting high losses. The user's stock assets will become the main breakthrough of the incremental distribution reform.

On October 8, 2016, the National Development and Reform Commission and the National Energy Administration issued the Administrative Measures for the Orderly Liberalization of Distribution Network Business (Fagai Jingti No. 2016 No. 2120), which clarified the scope of liberalization of distribution business.

In principle, the distribution network refers to the voltage level of 110 kV and below.

Power grids and local power grids such as 220 (330) kV and below voltage level industrial parks, such as economic development zones, in addition to the stock assets of power grid enterprises, the stock distribution network invested, constructed and operated by other enterprises.

Power distribution is the power system.

It is directly connected to the user and distributes electrical energy to the user. The power distribution system is composed of a distribution substation, a high-voltage distribution line, a distribution transformer, a low-voltage distribution line and the corresponding control and protection equipment.

The distribution system is composed of a distribution substation (usually the transmission voltage of the power grid is reduced to a distribution voltage), a high-voltage distribution line (that is, a voltage of more than 1 thousand volts), a wide wheel, a distribution transformer, a low-voltage distribution line (a voltage below 1 thousand volts) and the corresponding control and protection equipment. The distribution voltage is usually 35 60 kV and 3 10 kV, etc.

As the name suggests, high and low voltage power distribution engineering is a power distribution equipment that connects high-voltage distribution cabinets, low-voltage switchgears and connecting cables. General Electricity Supply Bureau.

The substation uses a high-voltage distribution cabinet, and then a transformer to a low-voltage switchgear, and a low-voltage switchgear to a switchboard for each electricity.

Control box, switch box.

Inside is nothing more than putting some switches, circuit breakers, fuses.

Buttons, indicators, instruments, wires and other protection devices are assembled into an integrated power distribution equipment.

The power capacity increase fee is also the electricity supply (distribution) subsidy fee. HiddenIt consists of two parts: the electricity supply fee and the distribution fee.

The power supply subsidy refers to the construction cost of the external power supply project of the split search hall with a voltage level of more than 10,000 volts and its supporting facilities (auxiliary production, living welfare and other facilities in the estimated budget of the project) that the user shall bear;

The distribution subsidy refers to the construction cost of external power supply projects and supporting facilities of 10 thousand volts (including 6 thousand volts) and below that should be borne by the user.

It is the construction cost of external power supply project and its supporting facilities.

Power capacity increase refers to the fact that in the process of production and operation, due to the expansion of production capacity demand, the original application for the use of electricity capacity (usually calculated according to the capacity of the transformer, the unit is KVA) can no longer meet the needs of production and operation, and must apply for capacity increase on the original basis.

If the electricity consumer needs to increase the capacity, it must submit a written application to the legal power supply entity (the stove draft power supply department), and issue the relevant application materials of the power consumer, which can only be carried out after the power supply party reviews and approves.

2. The maximum capacity of single-phase meter capacity increase is single-phase 12kw (60A), and the maximum capacity of three-phase meter capacity increase is three-phase 40kw (60A);

3. If the villa originally installed as a single-phase meter, and the external three-phase power supply conditions are available, it can be accepted to increase the capacity of Fan Yin Xiaowei.

Power capacity increase. It refers to the production and operation of the electricity consumer.

In the process, due to the expansion of production capacity demand, the original application for the use of electricity capacity (usually calculated according to the capacity of the transformer, the unit is kva) can no longer meet the current production and operation needs, and must apply for an increase in capacity on the basis of the original.

The electricity capacity increase fee is the common name of the power supply (distribution) subsidy fee, which includes two parts: the power supply subsidy and the distribution subsidy. Among them, the power supply subsidy refers to the voltage level of more than 10 thousand volts that the user should bear.

the construction cost of the external power supply project and its supporting facilities (auxiliary production, living welfare and other facilities in the project budget); The distribution subsidy refers to the construction cost of external power supply projects and supporting facilities of 10 thousand volts (including 6 thousand volts) and below that should be borne by the user.

Power capacity increase refers to the enhancement of the power transmission capacity of transmission lines or substation equipment through a series of technical means, so as to improve the reliability, stability and safety of the power grid. At present, power capacity increase has become one of the important means to improve the operation capacity of the power system.

With the growing demand for electricity, the increase in grid capacity has become an inevitable choice for the power industry. The traditional way is to expand power facilities, but the environmental pollution and waste of resources caused by it are difficult to ignore. In contrast, power capacity increases are more environmentally friendly and economical.

The technical means of power capacity increase mainly include:

1.Upgrading and renovating transmission lines, using new technologies such as conductors and vertical isolators to improve the load capacity and transmission efficiency of the lines;

2.Optimize substation equipment, increase the capacity of transformers and switchgear, and enhance the carrying capacity of equipment;

3.The use of double return to lift the number of wires and the use of two cables for round-trip power transmission, the power grid capacity is doubled;

4.Use intelligent substation technology to comprehensively upgrade the substation, improve the control, protection and automation level of the equipment, and improve the operation efficiency and safety.

Power capacity increase can not only improve the reliability and stability of the power grid, but also meet the growing power demand, alleviate the imbalance between power supply and demand, and promote the sustainable development of energy. However, at the same time, it is necessary to pay attention to prevent the overload of equipment after capacity increase to ensure the stable operation of the power system.

The use of electric capacity increase is a stable adjustment method of the power system. Often, load changes in the power system are complex and difficult to regulate and balance with conventional generator sets and transformers. Electrical capacitance enhancement technology increases the capacity of the power system by introducing corresponding capacitors into the power system, thereby improving the voltage and stability of the power system.

This method can improve the reliability and stability of the power system in the case of load fluctuations in the power system.

In addition to improving the stability of the power system, galvanic capacity enhancement technology can also better control the current and voltage in the power system. By adding capacitors to the power system, the frequency response of voltage and current can be effectively controlled, so as to ensure that the load change of the power system can be better regulated and balanced. At the same time, the electric capacity increase technology can also save the operating cost of the power system, making it more energy-saving and environmentally friendly.

In addition, electrical capacity enhancement technology can also be used to leak or improve the load capacity and overload capacity of the power system, increase the load rate of the power grid, and thus improve the life and reliability of the power system. For the power system in some rural and remote areas, the power capacity increase technology can also effectively alleviate the problem of voltage instability and power shortage in the power system, improve the power supply efficiency of the power system, and promote the development and stability of the local economy.

In short, electric capacity enhancement is an effective power system control technology, which can increase the capacity and stability of the power system, improve the load capacity and life of the power system, save the operating cost of the power system, and promote the development and stability of the local economy. <>

Summary. Hello, the increase in capacity of residents is to increase the capacity of electricity, from the management refers to a kind of procedure, in the past, the capacity increase is required to spend a fee to increase the capacity, pay the capacity increase fee, and then you can replace the energy meter that adapts to it, so that you can use the corresponding capacity of electric energy.

Hello, the increase in capacity of residents is to increase the capacity of electricity, from the management of the hypocrisy refers to a kind of rental blind combustion procedures, in the past capacity increase is required to spend a capacity increase fee, pay the capacity increase fee, and then you can replace the electric energy meter that is suitable for its shirt, so that you can use the corresponding capacity of electric energy.

Technically speaking, capacity increase is also to modify the power receiving facilities to adapt to the pre-increased capacity. For example, in the past, the electricity capacity of our residents was 1kw, and the installed electric energy meter could only be connected to a few lights; Now increase to 8kw, to replace it with a 10 (40) A electric energy meter, it means that your lead acacia can use electricity current to reach 36A, but you need to account for the wire and switch, if the current capacity of the wire and switch is less than 40A, it needs to be replaced to prevent the occurrence of electrical overheating accidents. The technological transformation is divided into two parts, which are divided by assets; For the equipment (wires) on the power supply side above the general electricity meter, the assets are owned by the power supply enterprise, and if they need to be replaced, the power supply enterprise shall be responsible for replacement; The equipment (wires and switches) on the load side below the meter are owned by the user, and if they need to be replaced, they will be replaced by the user's own investment.
