变频电源在海上油气平台电网中的应用

Application of Variable Frequency Power Supply in Offshore Oil and Gas Platform Power Grid

在港口船舶岸电供电技术基础上,研究变频电源技术,将某合作油田群60 Hz交流电变换成适合于利旧FPSO的50 Hz交流电,以满足利旧FPSO移位初期无伴生气源期间的供电问题。以该项目为基础分析了适用于海上油气田微电网中大型变频电源变压器励磁涌流的抑制措施,为今后海油合作油田开发供电方案提供新思路。

Based on the shore power supply technology of port ships,the frequency conversion power supply technology is studied.The 60 Hz AC of a cooperative Oilfield Group is transformed into 50 Hz AC suitable for the old FPSO to meet the power supply problem during the period when there is no associated gas source at the initial stage of the old FPSO shift.Based on this project,the suppression measures of inrush current of large variable frequency power transformer in offshore oil and gas field microgrid are analyzed,which provides a new idea for the power supply scheme for the development of offshore oil and gas field in the future.
