Abstract: By introducing advanced inverter technology,the traditional soft startup mode of export pump on HYSY 161 platform is upgraded to inverter start mode,which not only improves the startup efficiency of the pump,but also greatly improves the stability of the power grid. After the renovation,the power grid fluctuation problem during the platform’s export is effectively improved,providing a solid guarantee for the stable operation of the platform. The production process of the platform is optimized,and energy consumption is reduced,achieving a win-win situation of economic and environmental benefits.

Key words: offshore platform, power grid, export pump, inverter
