摘　　要：在发电机变压器组保护整定中 ,整定者常因无据可查或资料各执一词感到无所适从而套用兄弟单位的整定定值 ,造成了许多隐患 ;同时存在对整定原则理解不透 ,致使定值错误的情况。文中对发变组保护中某些整定原则的可行性、合理性提出疑义 ,对有些保护的整定配合及现场实际问题提出自己的观点、看法。During the protection setting for generation transformer unit,because of the lack or contradictory of data, the setting values from other units are often adopted, which will cause potential problems. The misunderstanding of setting principles will also make setting errors. Author doubts the feasibility and rationality of current setting principles for generation transformer unit and puts forward his opinions on the protection setting coordination and practical site problems.
