Description
Summary:In this paper a distribution system of 2 MVA, 11 KV standalone generator is feeding a group of six branches of pulse width modulation (PWM) drive nonlinear loads, such a distribution power system is used in oil fields drilling rigs, each branch is fed through a step down transformer of 11/0.4 KV and of capacity proportional to its branch load rating. For this group of nonlinear loads, the total current harmonic distortion (ITHD) and total voltage harmonic distortion (VTHD) are calculated at the point of common coupling (PCC#1) which show that the system failed to meet IEEE Std 519 harmonic limits. A shunt passive single tuned filters are designed to mitigate (ITHD) and (VTHD). The addition of these filters to this power system were effective in making it compliance with IEEE Std 519.
