差动保护是海上生产平台配电系统的主保护之一,广泛应用于发电机、变压器和海底电缆等关键设备。从实际工作经验和案例出发,详细分析了发电机差动保护、变压器差动保护和海缆差动保护的相同点和不同点、发现的问题及处理方法。最后,明确了差动保护对海洋石油平台配电系统的重要性,需进一步加强对差动保护的研究和应用。
Differential protection is one of the main protection systems for distribution platforms in offshore production platforms and is widely used in key equipment such as generators, transformers and submarine cables. Starting from actual working experience and case, the similarities and differences between differential protection of generator, differential protection of transformer and differential protection of submarine cable are analyzed in detail. The problems and solutions are analyzed. Finally, the importance of differential protection to the offshore oil platform power distribution system is clarified, and the research and application of differential protection needs to be further strengthened.
