Abstract

Existing conditions in industrial ac–dc power systems may result in significant commutation resistances. If the resistance to reactance ratio of the commutation impedance is high, significant errors can result in load-flow studies which neglect the resistive portion. A method is presented for inclusion of a resistance–inductance fed bridge rectifier in a Newton–Raphson (N–R) load flow program. Polar form of the power flow equations is assumed. An example problem is provided for comparison.
