摘　　要：孤岛电站受外界负载的波动影响很大,当各机组负荷分配性能不好时,可能会导致个别机组保护停机。文章介绍了柴油发电机组调速、调压系统的结构及特点,对多机组并列运行产生的问题进行分析,最后根据孤岛电站本身的特点进行控制系统硬件及功能的设计,解决了有功无功分配不均及外部大负载启动时频繁跳机的问题。The power generation of island power station is greatly affected by the fluctuation of external load.When the load distribution performance of each unit is not good,it may lead to individual unit protection shutdown.The structure and characteristics of the speed regulation and pressure regulation system of the diesel generator set are introduced,and the problems caused by the parallel operation of multiple generator sets are analyzed.Finally,the hardware and functions of the control system are designed according to the characteristics of the isolated island power station,which solves the problems of uneven distribution of active and reactive power and frequent trips when the external large load starts.
