2. Summary of second chapter

To facilitate the mentioned goals in Introduction Section , Chapter 2 written by Alexandru Băloi and Adrian Pană proposes a method for network harmonic impedance determination, practically. The network harmonic impedance has been used as a tool to predict the harmonic condition amplifications in the case of reactive power compensation by capacitor banks [4]. Based on the measured network harmonic impedance, a quick method has been developed to

anticipate the harmonic voltage and current amplifications. Amplification factors have been calculated depending on the equivalent harmonic impedance of the network seen in the compensation bus [5]. A distribution network containing harmonics has been modeled, and then harmonic impedance has been determined in different operating conditions using MATLAB Simulink. Using the measured values and the capacitive reactance of the capacitor bank, the amplification of the harmonic voltages and currents has been estimated by calculus [6, 7]. To validate the method, the obtained results have been compared with the values obtained by simulation after the connection of the capacitor bank to the network. The chapter has proved that the network harmonic impedance is a useful tool to estimate the harmonic amplification caused by power factor correction using shunt capacitor banks.
