Hence, the use of detuned reactors in series with capacitors offers higher impedance for harmonics, thus eliminating the risk of overload in capacitors. The inductance value of detuned reactors is selected such that the resonance frequency is less than 90% of the dominant harmonic in the spectrum.
Function and working principle of the capacitor compensation cabinet the function of the compensation cabinet is: the current is 90 degrees ahead of the voltage, and the parallel connection of capacitors is used to increase the line voltage and reduce the reactive power loss. 1. In the actual power system, most of the loads are asynchronous motors.
Capacitor banks, a common feature in power systems, are employed to optimize power factor and enhance overall system efficiency. However, the integration of capacitors introduces the potential for resonance issues, which can result in elevated voltage stress, excessive currents, and equipment failures.
The capacitor has the function of "connecting AC and isolating DC", that is, in the AC circuit, the frequency characteristic of capacitive reactance is used to "connect high-frequency AC and block low-frequency DC". Capacitors are capacitive loads, mainly used to compensate reactive power and store energy.
This resonance can be avoided by putting a detuned reactor in series with the capacitor. The reactor shall be such that the tuning frequency with the capacitor shall be less than the dominant harmonics. This combination of power factor correction capacitor and detuned reactors behaves inductively to frequencies above the tuning frequency.
Reactor capacity = matching capacitor capacity x reactance rate. For example, if 50kvar capacitor is connected in series with 7% reactor, then reactor capacity = 50kvar x 7% = 3.5kvar. Reactance ratio refers to the ratio of reactance value of series reactor to capacitance reactance value of capacitor bank.

When selecting reactors (7%), the voltage at the capacitor terminals in a 400V system rises to 430V, so use 0.45kV or 0.48kV capacitors instead of 0.415kV ones. Comparatively, 0.48kV capacitors are more reliable in terms of voltage endurance but reduce compensation capacity, requiring comprehensive consideration.
This paper aims to provide an in-depth understanding of detuned reactors, their role in mitigating harmonics, and how they prevent resonance in capacitor banks.
