Reactive power compensation is the process of connecting devices with capacitive power loads and inductive power loads in the same circuit, where energy is exchanged between the two types of loads. In this way, the reactive power required by inductive loads can be compensated by the reactive power output by capacitive loads. Let's take a look at the effects that can be achieved by using reactive power compensation.
1. According to the power factor of the electrical equipment, the energy loss of the transmission line can be calculated. Through on-site technical transformation, power factors lower than the standard requirements can be made to meet the standard, achieving the goal of energy conservation.
2. Adopting reactive power compensation technology to improve the power factor of low-voltage power grids and electrical equipment has become an important measure for energy-saving work.
3. Reactive power compensation refers to the use of reactive power compensation equipment to provide necessary reactive power, in order to improve the power factor of the system, reduce energy consumption, improve the voltage quality of the power grid, and stabilize equipment operation.
4. To reduce power loss, the power distribution in general factories has a power loss of about 2% -3% depending on different lines and load conditions. By using capacitors to increase the power factor, the total current is reduced, which can reduce the power loss at the supply and consumption ends. SVG reactive power compensation
5. Improve power supply quality, increase power factor, reduce total load current and voltage drop. Installing capacitors on the secondary side of transformers can improve power factor and increase secondary voltage.
6. Extend the lifespan of the equipment. After improving the power factor, the total current of the line is reduced, which reduces the capacity load of transformers, switches, and other machinery and equipment that are close to or already saturated. Therefore, it can reduce the temperature rise and increase the lifespan (for every 10 ° C decrease in temperature, the lifespan can be doubled)
7. Meet the monitoring requirements of reactive power compensation in the power system and eliminate fines caused by low power factor.
8. Reactive power compensation can improve power quality, reduce power loss, tap into the potential of power generation and supply equipment, and reduce user electricity expenses. It is an energy-saving measure with low investment and fast results.
