Marine Drilling Platform Power Plant Modeling And Harmonic Analysis

With the rapid development of offshore oil and gas exploration anddevelopment of the cause of marine drilling and production platforms have beenmore and more attention in the world as one of the very important equipment.Marine drilling platform power plant involving marine drilling and productionplatforms power system, to become one of the most important system of marinedrilling platforms, marine drilling platform power plant modeling and harmonicanalysis of power system and its related theory and technology part of.Marine drilling platform power plant modeling based on actual ocean drillingand production platforms station, the use of system modeling principles and systemsimulation, power system analysis, power system stability and reliability analysistechnology, marine drilling and production platforms topological structure andworking principle of the power station, a mathematical model of basic power systemunit of power plant systems, power grids, non-linear load, and ultimately theestablishment of marine drilling platform power plant model.Marine drillingplatform to power plant systems and other power systems, will also be harmonictroubled, and more significantly due to the smaller power plant capacity, stabilityand reliability of the harmonic problems of power plant systems and other powerindicators Therefore, we must on the harmonic analysis of power plant systems.The main content of this paper the following aspects:1、The composition of the marine drilling platform power plantThe composition and characteristics of the power plant system of marinedrilling and production platforms, offshore oil931jack-up drilling platforms, forexample, detailed analysis of the parameters of the various components.2、Power plant modeling and simulation of marine drilling and production platformsPower plant according to the marine drilling platform structure, workingprinciples,operating characteristics, first create the various parts of the mathematicalmodel, and then set up a mathematical model of the entire marine drilling platformpower plant, a single generator sets and generator sets in the impact of heavy loadthe start when the next simulation, the simulation by changing the two rectifierconduction angle, the bus voltage of the power plant system of marine drilling andproduction platforms.3、Harmonic Analysis and SimulationPower plant power quality problems of marine drilling and productionplatforms, as well as the hazards of the harmonic problem of the power system, theanalysis of marine drilling platform, the power plant model in the simplified harmonic source systems division of responsibility, and describes two detectionharmonic (harmonic detection method based on instantaneous reactive power theoryand the HHT method). Then were analyzed by EMD mode decomposition ofharmonic sources in the case of multi-harmonic source bus voltage.
