Application Fields
Series reactor: reactive power compensation, new energy stations, electrical railways, metallurgy, petrochemical and other enterprise users, used to suppress capacitor inrush current and harmonic amplification.
Parallel reactor: ultra/extra-high voltage transmission, new energy collection, used for line capacitive reactive power compensation and voltage stability control.
Usage
Series — used in series with high voltage shunt capacitor banks to suppress grid harmonics (such as 3rd and 5th harmonics) and limit closing inrush current during capacitor switching (up to 10-20 times the rated current). It also forms a resonant circuit with the capacitor to absorb specific order harmonics, ensuring stable operation of the power system.
Parallel — connected in parallel to transmission lines or the low-voltage side of substations to suppress power frequency overvoltage by compensating capacitive reactive power of the line, maintain system voltage stability, especially suitable for long-distance transmission scenarios, and can also suppress high-order harmonics to prevent resonance and improve grid power quality.
