CAREER: Condition-Based Maintenance of Electric Power Systems

该项目将专注于使用移动传感器监测电气绝缘。他们的网络将适应对电能质量敏感的客户和高度竞争但注重成本的放松管制的电力行业提出的全方位的空间和时间分辨率要求。几种几乎相关的传感器技术将被组合在一个系统中，以非破坏性地评估绝缘电缆和电力设备中的老化状态、早期故障的存在和故障部分的准确位置。移动式微制造平台将用于定期、全面和按需驱动绝缘状态的纵向扫描，而传统的固定传感器将为多传感器诊断提供系统范围的信息。该项目将带来分布式电力系统的新概念，特别是地下电缆，其中整个网络将由自动“爬行器”定期测试。主要的传感机制将包括边缘电场介电测量、声传感和红外传感。一旦移动平台的第一个原型完成，可能会安装更多的传感器。通信链路和设备运行的电源将决定移动平台的最大射程和小型化方面。

This project will focus on monitoring of electrical insulation with mobile sensors. Theirnetwork will accommodate a full range of spatial and temporal resolution requirements posed by powerquality sensitive customers and a highly competitive yet cost-conscious deregulated power industry. Severalmost relevant sensor technologies will be combined in a single system to nondestructively evaluate agingstatus, presence of incipient faults, and exact location of failing sections in insulating cables and powerequipment. A mobile micro-manufactured platform will be used for periodic comprehensive and need-drivenlongitudinal scanning of insulation status, whereas traditional of stationary sensors will providesystemwide information for multi-sensor diagnostics. The project will lead to a new concept of distributionpower systems, especially for underground cables, in which the entire network will be periodically testedby automatic "crawlers". Prime sensing mechanisms will include fringing electric field dielectrometry,acoustic sensing, and infrared sensing. Additional sensors are likely to be installed once the first prototypeof the mobile platform is complete. Communication links and source of power for device operation woulddetermine maximum range and miniaturization aspects of mobile platforms.
