High voltage reactive power compensation, what are the effects of high voltage on reactive power com

Regardless of the voltage level, reactive power compensation is divided into capacitive compensation and inductive compensation. However, the compensation is usually capacitive compensation, because the capacitive compensation is very small, usually only in the process of road transmission, the mutual inductance between the lines is capacitive, and most of the loads are capacitive inductive loads that require capacitance compensation. The difference between them is that the circuit is turned on at the moment, whether the reactor bears the impact or the capacitor bears the impact, because our reactor is produced by ourselves, and the impact resistance is strong, so I generally connect the reactance first.

The reactor and the capacitor form an LC tuning loop for a specific harmonic, so that the impedance of the filter branch to a certain harmonic is very low, and this filter branch plays the role of filtering. The selection of reactor is related to the capacitance of the capacitor and the number of filtering. The choice of contactor depends on the voltage level, current size, breaking capacity, and whether it is frequently switched, like 10kV 6kv usually uses vacuum contactor, but pay attention to:

In 10kV and 6kV systems, the vacuum contactor is not fully suitable for frequent switching. The capacitor selection is mainly the voltage level, the capacity of compensation, the elevation of the capacitor voltage by the reactor, and so on.

A reactance is only related to the capacitance of the capacitance, and has nothing to do with the number of capacitors.

There are many things to pay attention to about the design of the filter, such as the number of harmonics, the size of harmonics, the short-circuit capacity, etc., not a few words can be finished, if necessary, you can q me or send me an email.

1. Active power determines frequency, reactive power determines voltage, when the voltage is high, the capacitor can not be put in, and then the capacitor will make the voltage higher, and the high voltage will also harm the safety of the capacitor itself;

2. The voltage is very high during the day, and the voltage is higher at night, so the capacitor can not be put into it, and the high voltage is not only harmful to the capacitor, but also harmful to other electrical equipment; Hungry beat.

3. If the power factor is low, especially when paying the electricity bill, you should pay the "power factor" fine, then the power factor should be increased, the easiest way is to change the section switch of the transformer, reduce the voltage of the transformer, and then put in the capacitor;

4. If your load is relatively small, you can replace the transformer with a smaller capacity, such as 50kva, or 30kva, which not only reduces the power loss of the transformer itself, but also saves electric energy;

5. If the power consumption capacity is small, the reactive power compensation that needs to be adjusted should also be fine, and the capacitor with small capacity is required, and the compensation amount of a single capacitor should not be greater than 1 3 of the capacity of a single electrical equipment. If the capacitance of the capacitors in the compensator is not consistent, the compensator controller should be adjusted and set.

Reactive power compensation, referred to as reactive power compensation, plays a role in improving the power factor of the power supply system of the power grid, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency and improving the power supply environment. Therefore, the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid.

On the contrary, if the selection or use is improper, it may cause many factors such as power supply system, voltage fluctuations, harmonic increases, etc.

Hello, the high-voltage reactive power compensation device can be provided by the power supply enterprise or the user himself. According to the provisions of the "Measures for Adjusting the Electricity Charge of the Power Factor of Accompanying Return", the power factor standard is the assessment standard, the standard, and the preferential standard. If the load power factor is lower, the electricity fee will be increased, but if it is higher, you may get a discount on the electricity fee.

Hello, about the provision of high-voltage reactive power compensation device, the following schemes can be considered according to different situations:1If it is a reactive power demand caused by industrial and commercial users, the reactive power compensation device should be provided and installed by the power users themselves.

This is in accordance with the provisions of the Law on the Management and Rent Management of Reactive Power Compensation for Electricity Users. 2.If the reactive power loss of the power grid itself needs to be compensated, the reactive power compensation device can be configured by the power generation enterprise or the power grid enterprise itself.

3.For important public facilities such as airports, hospitals, etc., if reactive power compensation has an important impact on power quality, reactive power compensation devices can also be provided by power grid enterprises or relevant departments. 4.

For the reactive power compensation of residential users, the power distribution enterprise can set up a compensation device, but the cost may be passed on to the user's electricity price. 5.If the capacity of the reactive power compensation device is large, the installer can apply for the joint construction of the compensation device with the power generation enterprise or the power grid enterprise, and the two parties can sign a power purchase and sale agreement.

6.If conditions permit, virtual reactive power compensation can also be considered to save hardware investment. To sum up, the provision of reactive power compensation rental device needs to be determined according to the actual situation, and the user-provided mode is mostly adopted, and a more economical compensation scheme can also be realized through multi-party cooperation.

Summary. The reactive power compensation is particularly high, which will make the voltage of the power system increase and affect the life of electrical equipment, easy to produce overvoltage and resonance to affect the power equipment, and reduce the power quality due to the increase of power in the line.

The reactive power compensation is particularly high, which will increase the voltage of the power system and affect the life of electrical equipment, and it is easy to produce such as selling overvoltage slag and resonance to affect power equipment, and the power quality will decrease due to the increase of power in the line.

What is the reason for the reactive electricity bill of more than 3000.

The reason for the reactive power socks is that the reactive power compensation of the line or equipment is insufficient, resulting in the power factor of the yard is lower than the power specified by the power supply department, and the power factor is lower than the reactive power charge charged below.

Hey. In the 31 years that our company has been engaged in the research and development, production and sales of reactive power compensation equipment, there are often novices who ask us similar questions. This way:

The monthly average power factor is generally used by the power supply company to assess the user's data, and he uses the active electricity consumption of the month and the reactive power consumption of the month to calculate, and the calculation formula is:

Monthly average power factor = monthly active power [(square of monthly active power + square of monthly reactive power)open squared].

Say a few more words: because the technology of the conventional compensation cabinet is very mature, and the components used in the cabinet are also very mature, so a large number of small factories and even small roadside electrical appliances stores dare to make compensation cabinets, which is a very fatal thing, because the technology of the industry is mature, does not mean that the producer's process and technology are mature, and does not mean that the producer does not use fake and inferior components and materials, especially a large number of low-cost cottage compensation controllers flood the market, ** looks very attractive, but a fine is enough for you to bear. Therefore, it is necessary to use a qualified manufacturer's cabinet.
