【摘要】 针对海洋油田测井装置,对其驱动液压泵电机的供电方式进行了研究,比较分析了七种供电方式的优缺点,提出了一种最有应用前途的马达电机供电方式。这种供电方式克服了传统的"调压器加变压器"的海洋油田测井电源方案的诸多缺点,具有体积小、质量轻、电压调节方便、起动电流小、动态响应快、智能化程度高等优点。这种供电方式由多个IGBT功率变换单元组成,经过了多个电压变换环节,实现了从单相AC110V低压至双相AC600～AC1200V中压的变换。该电源装置设计方案新颖、技术先进、性能指标优越,可以在海洋油田测井行业内推广应用。更多还原

【Abstract】 For marine oil well testing equipment,the mode of power supplies for driving hydraulic pump motor was studied.Seven kinds of advantages and disadvantages of power supplies were analyzed comparatively.The mode of motor power supply of the most promising application was proposed,which overcame the many disadvantages of traditional mode of marine oil well testing,voltage regulator and transformers,mode,and had many advantages,for example,small size,light weight,convenient voltage regulating,small starting current,fast dynamic response,high intelligence,and etc.The power supply consisted of many IGBT power conversion units,which had many AC/DC/AC-AC/DC/AC voltage conversion links,and achieved the conversion from the single-phase low voltage AC 110 V to the two-phase medium voltage AC 600-AC 1200 V.The power supply equipment has innovative designing,advanced technology,and superior performance,and can be promoted in the marine oil well testing industry.更多还原
