The broader impact/commercial potential of this I-Corps project is the development of a technology with the potential to substantially reduce downtimes and associated costs to electricity customers following power outages. This includes the cost to industrial consumers, such as production lines shutting down, as well as property/goods damage or life-threatening conditions to residential and commercial consumers (e.g. loss of heating system or refrigeration unit during a natural phenomenon). In addition, our technology provides a rich ground for scientific and technological advancement in the field of power system protection given its versatility and accuracy features. The proposed fault location technology is applicable in different research areas including transmission, distribution, microgrids and hybrid systems for overhead lines and underground cables. Furthermore, the unique visualization capabilities of our technology pave the way for its utilization outside of the realm of fault location and detection, such as for conditioning monitoring, fault prediction, and preventive maintenance, all crucial aspects for reliable and continuous delivery of electricity to consumers.This I-Corps project is based on the development of a method that reconstructs the complete fault line and produces a visually rich colormap in the space-time plane. This colormap clearly illustrates not only the fault location, but also the fault type and severity. The comprehensive data provided by this colormap is further processed to obtain a very accurate fault location estimation. Unlike existing methods, our method is not restricted to certain types of systems or fault conditions and, given its visual capabilities, it does not require the amount of time needed by existing tools to identify a fault. The technology relies on the combination of: versatility: applicable to any type of transmission system under any type of fault; accuracy: the reconstruction of the complete fault condition along the line allows exact pinpointing its position; and speed: its visualization features enable very fast fault location with low sampling rate, which translates into low computational burden.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是开发一项技术，有可能大大降低电力停电后电力客户的下降和相关成本。这包括对工业消费者的成本，例如关闭生产线，以及对住宅和商业消费者的财产/商品损害或威胁生命的条件（例如，在自然现象中失去加热系统或制冷单位）。此外，鉴于其多功能性和准确性功能，我们的技术为电力系统保护领域的科学和技术进步提供了丰富的基础。拟议的故障位置技术适用于不同研究领域，包括用于间接头线和地下电缆的传输，分配，微电网和混合系统。此外，我们技术的独特可视化功能为其在故障位置和检测领域之外的利用铺平了道路，例如用于调节监控，故障预测和预防性维护，所有这些方面都可以可靠，连续地向消费者传递电力。该结肠不仅清楚地说明了故障位置，而且说明了故障类型和严重性。进一步处理该结肠所提供的综合数据，以获得非常准确的故障位置估计。与现有方法不同，我们的方法不仅限于某些类型的系统或故障条件，而且鉴于其视觉功能，它不需要现有工具所需的时间来识别故障。该技术依赖于：多功能性：适用于任何类型的故障的任何类型的传输系统的组合；精度：沿线的完整故障条件重建允许精确指出其位置；和速度：其可视化功能使非常快速的故障位置具有低采样率，这转化为低计算负担。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来提供支持。
