Q: What are the roles of reactors in the power system? Â
Answer: Reactors used in power systems are commonly found as series reactors and shunt reactors. Series reactors are mainly used to limit the short-circuit current, and are also used in series or in parallel with capacitors in the filter to limit higher harmonics in the grid. Â
The working principle of the reactor:
The reactors in the 220kV, 110kV, 35kV, and 10kV power grids are used to absorb the capacitive capacitive reactive power of the cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors. The ultra-high voltage shunt reactor has various functions for improving the operating status of the reactive power of the power system, and mainly includes: (1) a capacitive effect on a lightly loaded or lightly loaded line to reduce the power frequency transient overvoltage. (2) Improve the voltage distribution on long-distance transmission lines. (3) Make the reactive power in the line at the light load as balanced as possible, prevent the irrational flow of reactive power, and also reduce the power loss on the line. (4) When the large unit is in parallel with the system, reduce the steady-state voltage of the power frequency on the high-voltage bus, so that the generators can be juxtaposed at the same time. (5) Prevent self-excitation resonance phenomenon that may occur in the long line of the generator. (6) When the neutral point of the reactor is used to pass the small reactance grounding device, the small reactor can also be used to compensate the phase and phase capacitance of the line to accelerate the automatic extinguishing of the submerged current, which is convenient to adopt.
