摘　　要：分析发电机励磁调节器过励保护、并网信号等原理,查找并网信号异常的原因。根据上述原因完成回路改造和完善。基于空载情况下的励磁电流值,重新设定励磁调节器AVR过励保护和限制定值。This paper analyzes the principle of over excitation protection and grid signal of generator excitation regulator, and finds out the cause of abnormal grid signal. According to the above reasons, complete the circuit transformation and improvement. Based on the excitation current value under noload condition, reset the over excitation protection and limit setting value of AVR.

关 键 词：励磁调节器 并网信号 过励保护 过励限制 保护定值
