摘要： 随着中国海油“碳达峰碳中和”行动方案的实施及渤海油田群岸电的接入,海上平台高耗能系统的节能控制改造尤为关键。以海上石油平台电伴热系统为例,结合海上平台电伴热系统节能发展现状,在阐述海上平台伴热系统结构、运行方式、控制策略的基础上,提出采用脉宽调制（PWM）控制伴热系统功率的节能设计方案,并对该方案在海上平台试用的节能效果及经济性进行了分析,肯定了其可观的经济社会效益。

Abstract: With the implementation of CNOOC’s “peak carbon dioxide emissions and carbon neutrality” action plan and the shore power connection of Bohai oilfield groups,the energy-saving control transformation of high-energy-consuming systems on offshore platforms is particularly crucial. Taking the electric heat tracing system on offshore oil platforms as an example,this paper provides an overview of the current status of energy-saving development of electric heat tracing systems on offshore platforms. The structure,operation mode,and control strategy of the current heat tracing system on offshore platforms are elaborated. An energy-saving design scheme of heat tracing system power controlled by thyristor is proposed. The energy-saving effect and economy of this scheme during its trial on offshore platforms are analyzed,affirming its considerable social and economic benefits.

Key words: offshore oil platform, electric heat tracing, energy saving, economy
