基于群岛可靠性供电研究

Research on Reliability of Power Supply Based on Islands

传统海岛供电方式多采用柴油发电机自行离网供电或通过海底电缆连接大陆联网供电,然而污染环境且成本极高。虽然,近些年岛屿使用分布式电源,但大多为孤岛离网,供电稳定性和可靠性不佳,亟需一种可靠的海岛供电方案。基于此,采用海岛群岛联网方案,包含能量控制器和设备装置改进的下垂控制两方面的研究,共同协调配合群岛间的分布式新能源发电出力和故障处理,大大提高了海岛供电的可靠性。

Traditional island power supply methods mostly use diesel generators to supply power off the grid by themselves or connect to the mainland to supply power via submarine cables.However,it pollutes the environment and is extremely costly.Although distributed power sources have been used in islands in recent years,most of them are isolated islands and off-grid.The stability and reliability of power supply are not good,and a reliable island power supply scheme is urgently needed.Based on this,this article adopts the islands and islands networking scheme,which includes the research of energy controllers and improved droop control of equipment and devices.They coordinate and cooperate with the distributed new energy power generation and fault handling between the islands,which greatly improve the reliability of island power supply.
