【摘要】 船舶电力系统的电压调节和无功功率分配密切相关。在同步发电机并联运行时,各并联运行发电机组之间稳定合理地分配机组间的无功负荷,是由各台发电机的励磁调节装置(AVR)来实现。本文根据船舶发电机两机并联后出现的严重安全隐患,分析了交流同步发电机组的电压调整特性及发电机并联运行时的无功分配特性,绘制了发电机的实际调压特性,根据发电机的工作要求进行了调整,解决了无功分配不均的故障。更多还原

【Abstract】 There had close relation between voltage adjustment and reactive power distribution in ship power system.When inparallel running for generators,how to share reactive power,it was decided by AVR.According to a serious fault in parallelrunning,this paper analyzed the voltage adjust characteristic and reactive power sharing characteristic,drawn the actual voltage adjustcharacteristic,according to actual demand for generators,adjustment had been done,the serious fault had been eliminated.更多还原
