The unique characteristics of source-grid-load in oilfield distribution networks make the power quality issues particularly prominent. The power quality assessment and comprehensive governance strategies for oilfield distribution networks are studied. By monitoring and tracing the harmonic characteristics of loads at a typical station, the types, features and distribution of harmonic sources are revealed, and the level of power quality is quantitatively assessed. Furthermore, aimed at the harmonic sources, a double-layer harmonic governance scheme using active and passive measures is proposed. Passive filters are designed based on reactive power compensation, and a harmonic optimization compensation objective function for the local power grid is established. Simplified geometric calculations combined with nonlinear programming algorithms are employed to find the optimal solution, thus determining the optimal placement and capacity of active filtering devices in the distribution network. Finally, the effectiveness of the proposed algorithm was validated using an IEEE 33-bus test system. In addition, governance experiments in oilfield distribution networks were carried out, and the overall harmonic performance was optimized with active filters of the minimal quantity and smallest capacity, reducing the voltage total harmonic distortion (THD) from 7.2% to 2.1% and current THD from 44.5% to 7.1%, thus proving the efficacy of the proposed scheme.
