Customized power quality control schemes and comprehensive evaluation method for an offshore oil platform

Aiming at the power quality problems existing in offshore oil platforms, this paper analyzes three typical power quality problems on a platform through actual measurement, such as high harmonic content, low power factor and voltage sag. Then multiple customized power quality control schemes were proposed, and by considering energy -saving, reliability, and economy, the weight of indicators was determined by AHP-EWM method, and different schemes were compared by the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Finally, the optimal scheme which balances management effectiveness, reliability, and economy was obtained, and its effectiveness was verified through electromagnetic transient simulation.
