某余热发电机组一次调频试验问题分析

摘要

The values of primary frequency compensation test are unable to meet the requirements in a waste heat power generation unit. The factors which influence primary frequency compensation test including digital electrical hydraulic (DEH) logical structure, the forming of main steam pres⁃sure, extraction and admission are analyzed.%某余热发电机组在一次调频试验过程中，调频幅值始终无法达到要求。分析了该余热机组DEH逻辑结构、主汽压力形成特点、抽汽供热和补汽等因素对机组一次调频试验的影响。
