为充分发挥柴油发电系统在孤立海岛微电网供电模式下的作用，并最大限度地降低孤立海岛微电网系统的建设费用，有必要对岛上传统老旧柴油发电系统的改造进行研究。针对传统老旧柴油发电系统在孤立海岛微电网供电模式下普遍存在的问题，提出了具体的改造方案，分别对柴油发电机控制器、调速器、调压器、自动化系统及通信网络等进行改造；并对改造后的柴油发电机与微电网之间的交互联系进行了分析。经改造后，柴油发电机能够实现与微电网控制中心的“四遥”功能，并通过与微电网中其它分布式电源以及储能系统的协调配合，参与孤立海岛微电网的整体运行控制，以保证微电网的稳定、可靠、经济运行。

To fully exert the role of diesel power generation system under isolated island microgrid power supply mode and minimize construction cost of isolated island microgrid system, it is necessary to study the modification scheme for traditional and old diesel power generation system on island. Aiming at common prob-lems of traditional and old diesel power generation system under isolated island microgrid power supply mode, a specific modification scheme is presented, according to which diesel generator controller, speed governor, voltage regulator, automatic system, communication network and so forth are modified respectively. Further-more, the interaction between modified diesel power generation system and microgrid is analyzed. After modi-fication, diesel power generation system can realize the four-remote functions with microgrid control center, and it can involve in the whole operation control of isolated island microgrid through coordinating with other distributed generation and energy storage system in microgrid and thus ensure stable, reliable and economical operation of microgrid.
