海上平台电能质量问题及其改善措施

Offshore Platform Power Quality Problems and Improvement Measures

目前大多数海上平台采用自发电的方式提供平台用电,电网容量小。另外平台上大功率设备占比大,钻井、采油等生产过程工况复杂,导致平台的供电电能质量存在无功变化快、谐波含量高及电压波动大等严重问题。文章结合实际应用项目介绍了目前常见的海上平台电能质量问题及改善措施,并对海上平台电能质量改善方法提出了一些建议。

At present,most offshore platforms provide platform electricity by means of self-generating,offering small power grid capacity.What’s more,on platforms,there is a large proportion of high power Equipments.The working conditions of drilling,oil extraction and other production process are complicated,resulting in the serious issues of quickly changes of reactive power,high content of harmonic wave and highly voltage fluctuate on platforms.Taking practical applications into account,the article makes an introduction to the normal quality problems and improvement measures of electricity energy of offshore platforms and offers some suggestions for improving Power Quality of offshore platforms.
