Harmonic Analysis and Control Solution of DC Driven Offshore Drilling Rig Power Station

By studying the working characteristics of DC-driven offshore drilling rig, this paper analyzes the generation mechanism and harm of harmonic in power station, compares the advantages and disadvantages of passive power filter and active power filter in harmonic control, and puts forward the solution of DC-driven offshore drilling rig harmonic control. In a DC drive offshore drilling rig power station as an example, establishes equivalent circuit of power distribution system harmonic analysis, builds simula tion platform of the SCR system. Through the actual measurement of harmonic parameters of the platform of power station, the harmonic components of each order are analyzed and calculated. According to the tuning relationship, the matching capacity of the filter device is determined and the elements safety is verified.
