摘　　要：研究发电机进相运行的重要性及其影响因素,分析欠励限制对机组进相运行的安全控制及其整定原则,通过现场进相试验,进一步说明发电机进相能力影响因数及欠励限制整定值与机组实测进相能力相关性,可供发电机组进相试验及欠励限制参数整定参考。The importance and influencing factors of leading phase operation of generators are analyzed.Safety control effect of the under-excitation limit on the leading phase operation and its setting principles are summarized.Then,with in-situ leading phase operation experiments,the relationships between the leading phase influencing factor,the under-excitation limit setting value and the measured leading phase capacity of generators are determined,which provides useful reference for the further study of the leading phase experiments and the setting of under-excitation limit parameters.
