摘要
该文阐述了大型火电机组低负荷辅机跳闸摸底试验的开展过程,对相关结果进行了分析,找出了低负荷辅机跳闸的特点以及当前控制机制的不足之处。在此基础上,围绕风机、制粉系统两大辅机的优化跳闸控制方式进行了分析,并对此种优化方式是否具备实用价值展开了结果论证。最终结果表明,该文基于大型火电机组低负荷工况下辅机跳闸发生原因而提出的解决方式具备可行性。
This paper describes the development process of low load auxiliary tripping test in large thermal power units,analyzes the relevant results,and finds out the characteristics of low load auxiliary tripping and the shortcomings of the current control mechanism.On this basis,the optimal trip control mode of fan and pulverizing system is analyzed,and the practical value of this optimization mode is demonstrated.The final results show that the solution proposed in this paper based on the causes of auxiliary machine trip under low load conditions of large thermal power units is feasible.
