Characteristics of reactive power compensation capacitor

Reactive Power Compensation Capacitor Characteristics:

① Reactive Power Compensation Capacitor is a capacitive reactive power supply source that operates for a long time under power frequency AC voltage.

② reactive power compensation capacitor's own active power loss is small, accounting for about 0.3~0.5 of the ordinary reactive capacity.

③ power capacitor device is simple, easy to use, maintenance workload is small, a less investment.

④ Due to the structural characteristics, excessive ambient temperature and operating voltage will affect its applicable performance and life, and even cause accidents.

⑤ The reactive power of the capacitor is proportional to the square of the voltage. When the system voltage decreases and more reactive power compensation is required, the reactive power of the power capacitor is reduced at this time, showing the lack of performance.

power capacitor is the power system reactive power compensation of the wrist, the operation of the parallel capacitor capacitive current offset rational current, so that the transmission components such as transformers, lines in the reactive power response is reduced, therefore, not only reduces the reactive power flow caused by the active loss, but also reduces the voltage loss, improve the power factor. So the use of parallel capacitors to stop the reactive power compensation at all levels of the power grid is the most common application of the power system.
