Algorithm for Selecting Cross-Capacitive Compensation Device Parameters with High Harmonics Accounted For

摘要

The article deals with the matters of reactive power compensation by means of capacitor banks with harmonic distortions in voltage and current, resulting from both their own nonlinear load and the same from third party consumers connected to the connection point shared by consumers. It is advised to reduce the capacitor bank currents overload by varying the reactive power compensation device parameters depending on the system resistance and the linear electric load parameters. Based on the characteristics obtained, capacitor bank parameters are selected in a manner that provides for their overload not exceeding planned values, and the maximum power factor would be provided. In addition, an algorithm is presented for compensation device parameters selection that accounts for minimum capacitors overload and the maximum network power factor.
