At present, the series reactors installed in capacitors can effectively suppress harmonics and closing inrush currents to reduce the impact of switching capacitors on the power grid. In addition, the series reactors can limit the passage of harmonics on the power grid through capacitors on a large scale, thereby protecting capacitors and switching switches. Therefore, series reactors are widely used in the operation of the power grid.
Line parallel reactors can compensate for the capacitive charging current of the line, limit the increase in system voltage and the generation of operating overvoltage, and ensure the reliable operation of the line.
Bus series reactors can limit short-circuit current and have high residual voltage on the bus. Connecting capacitors in series with reactors can limit high-order harmonics and reduce reactance.
The main function of a series reactor is to suppress high-order harmonics and limit closing inrush current, prevent harmonic damage to capacitors, and avoid excessive amplification and resonance of grid harmonics caused by the connection of capacitor devices. Parallel reactors are generally connected between the end and bottom of ultra-high voltage transmission lines to provide reactive power compensation. A reactor connected in parallel in the power grid to compensate for capacitive current. The reactor used for the full load test of the generator is a prototype of a parallel reactor. Due to the attraction of alternating magnetic fields between segmented iron core cakes, the noise of iron core reactors is generally about 10dB higher than that of transformers of the same capacity.
