Shunt Reactor is an absorber of reactive power,it is same as power transformer but it has only one winding per phase as compared to power transformer.
1.Increasing the energy efficiency of the system. It is the most compact device commonly used for reactive power compensation in long high-voltage transmission lines and in cable systems. The Shunt Reactor can be directly connected to the power line or to a tertiary winding of a three-winding transformer.
2.Improving power quality and reducing transmission costs .
Over long transmission lines, reactive power is generated as an effect of the capacitance be- tween the lines and earth. The reactive power cannot be used for any application and should be balanced to reduce energy losses. Shunt Reactors absorb the reactive power, thus increasing the energy efficiency of the system.
Jingcheng Shunt Reactors increase the energy efficiency of power transmission systems by improving power quality and reducing transmission costs.Improve the utilization rate of electric energy and extend the service life of electrical equipment.
3.Improving voltage stability at low load
At low loads, the voltage increases along the transmission line. A Shunt Reactor reduces the voltage increase, keeps the voltage within the de- sired limits, and contributes to the voltage stabil- ity of the system.
What kind of place use Shunt Reactor ？
1. When the load of transmission and distribution system is no-load or light load, it is capacitive to reduce the power frequency transient overvoltage.
2.Improve voltage distribution on long transmission lines. Prevent possible self excitation resonance of generator with long line.
3.Reduce the power frequency steady-state voltage on the high-voltage bus when the large unit is paralleled with the system, so that the generator can be paralleled in the same period.
4.When the neutral point of the reactor is connected to the small reactance grounding device, the small reactor can also be used to compensate the phase to phase and phase to ground capacitance of the line, so as to accelerate the automatic extinction of the potential supply current and facilitate the adoption of single-phase automatic reclosing.
What are Shunt reactor advantages ?
Shunt Reactors are the most compact and cost-ef- ficient way to compensate for reactive power generation in long high-voltage power transmis- sion lines and in cable systems. They can be per- manently used in service to stabilize power trans- mission, or switched in under light-load conditions for voltage control only.
What kind of types of Shunt Reactors do we have ?
Oil-immersed reactor, Dry-type Air-core reactor, Iron-core reactor .
