Capacitor harmonic amplification effect is analyzed theoretically

Harmonics and low power factor compensation capacitors in parallel loop meritorious cause measurement error increases, thereby affecting bus power balance. In this paper, a capacitor harmonic amplification effects of the theoretical analysis, harmonic analysis of the shunt capacitor equivalent circuit analysis of the role of mcb circuit breaker and reactor reactance rate selection, the parallel capacitor circuit capacitors in parallel and series reactor voltage and current theoretical calculations. Shunt capacitor Circuit breaker  amplification system with Voltage stabilizer  and branch equivalent reactance ratio related to the capacitor branch to join the series reactor, it can reduce the number of parallel resonant harmonics, reduce severe enlarged area width.
