基于小波分析的次同步振荡检测研究

摘要:

考虑次同步振荡和轴系的特殊关系?使用小波变换实时监测轴系次同步分量?并在突发故障的情况下?及时检测到突发故障的奇异点?达到及时报警和采取相应对策的目的。该方法简单实用?监测设备易于实现。

Abstract:

Because of the special relationship between SSO （subsynchronous oscillation） and shafting of turbine－generator set?wavelet analysis is applied to torsional oscillation real－time detection and fault feature extraction of sudden fault?so that it can alarm in time and take some corresponding countermeasures．The method is simple and practical?and the detection device is easy to be realized．
