Twin Signal Signature Sensing: Application to Shorted Winding Monitoring, Detection and Localization

9523323 El-Sharkawi提出了一种基于双信号特征传感的电力系统绕组短路匝数监测、检测和定位方法。这类设备包括同步汽轮发电机、转子、变压器和电机。到目前为止，还没有有效的方法来做到这一点。实施后，该技术将对通过定期在线短路绕组监测和诊断来提高设备性能具有不可估量的价值。这项技术在应用于可靠性不确定的老化电力设备时将特别有效。拟议的项目将在南加州爱迪生的合作下进行，爱迪生将提供实物支持。南加州爱迪生公司对监测涡轮发电机励磁回路的短路匝数特别感兴趣。拟议技术的成功部署将节省数百万美元，因为它减少了直接维护性费用，并且(1)节省了在转子停机期间所需的替代更昂贵的能源(例如核能)的额外成本，以及(2)通过例如避免因屈曲而造成的损坏来延长机器的使用寿命。***

9523323 El-Sharkawi Using twin signal signature sensing, we propose a method to monitor, detect and localize shorted turns in power system equipment with windings. This equipment class includes synchronous turbine-generators, rotors, transformers and motors. There has, to date, been no effective way to do so. When implemented, the technology will be invaluable for enhancing device performance through periodic on-line shorted winding monitoring and diagnostics. The technology will be especially effective when applied to aging power equipment whose reliability is uncertain. The proposed project will be undertaken with the cooperation of Southern California Edison who will provide in- kind support. Southern California Edison is particularly interested in the monitoring of shorted turns of the field circuit of turboalternators. Successful deployment of the proposed technology will save millions of dollars by decreasing direct maintainability expense and (1) by saving the added cost of alternate more expensive energy sources (e.g. nuclear) required during the rotor's down time and (2) by increasing the operational life of the machine, through, for example, avoidance of damage due to buckling. ***
