HYSY161天然气发电机组快速脱扣改造探索

On the Fast Tripping Reform of Gas Generator for HYSY161 Offshore Platform

海洋石油161平台发电机组当2台发电机组并联运行而其中1台因紧急故障突然关断时,为避免出现生产关停和安全事故就需要采取保护措施,即快速脱扣,也就是电力系统的自动卸载。提出改造思路及改造方案,使快速脱扣系统成为平台电力系统安全平稳运行的可靠保障。

The problems of the generator group in HYSY161 offshore platform are analyzed. When 2 generating units of op- erate in parallel and 1 generating unit shutdown suddenly for emergency, the measure of fast tripping needs to be taken to avoid production stop and safety accidents, the protective measures unloads the power system automatically. Some innovation ideas and plans are set forth. The practices show that fast tripping system is an important guarantee for the safe and stable operation of the power system platform.
