摘　　要：在孤网运行条件下,辅机的启动顺序对于发电机组的安全稳定运行至关重要。本文以印尼某生物质发电项目为例,分析了不同辅机启动顺序对系统电流冲击和潮流的影响。通过对三种不同辅机启动顺序的电流和潮流计算对比,提出了最优启动顺序,并提出合理的负荷分配和潮流管理建议。结果表明,合理的启动顺序能够有效减少系统的电流冲击,优化系统的潮流分配,确保系统的稳定运行。本文为类似项目的设计和运行提供了技术参考。In islanded power plant,the start-up sequence of auxiliary systems is critical for the safe and stable operation of the power plant unit.This paper analyzes the impact of different auxiliary system start-up sequences on system current surges and power flow,using a biomass power generation project in Indonesia as an example.By comparing the current and power flow calculations of three different start-up sequences of auxiliary systems,the paper proposes an optimal start-up sequence and offers recommendations for reasonable load distribution and power flow management.The results show that a well-designed start-up sequence can effectively reduce current surges,optimize power flow distribution,and ensure stable system operation.This study provides technical references for the design and operation of similar projects.
