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

小行星9523323 利用双信号特征传感，我们提出了一种方法来监测，检测和定位电力系统设备的绕组短路匝。 这类设备包括同步涡轮发电机、转子、变压器和电动机。 到目前为止，还没有有效的方法来做到这一点。 一旦实施，该技术将通过定期在线短路绕组监测和诊断来提高设备性能。 该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。拟议中的项目将与南加州爱迪生公司合作进行，后者将提供实物支持。南加州爱迪生公司对监测涡轮交流发电机励磁电路的短路匝数特别感兴趣。 所提出的技术的成功部署将通过以下方式节省数百万美元：减少直接维护费用;（1）节省在转子停机时间期间所需的替代的更昂贵的能源（例如，核能）的增加的成本;以及（2）通过例如避免由于屈曲而导致的损坏来增加机器的操作寿命。 ***

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. ***
