Wide-area monitoring of the power system is becoming increasingly important as the UK is transitioning to a net-zero economy. To prevent blackouts, high-performance distributed sensors are required to provide sufficient real-time data for rapid control and protection of the power system. Moreover, extensive condition monitoring of often dynamically-rated power lines and cables is required as the grid undergoes unprecedented stresses due to the volatile loading scenarios and new weather extremes.Synaptec's distributed photonic sensing technology is an ideal solution to this challenge as it piggybacks on the grid pre-installed fibre and offers cost-effective coverage of large geographic areas using high-performance passive sensors, not requiring buildings, power supplies, communication infrastructure, or GPS signals. Synaptec's customers have implemented novel control or protection schemes with a fraction of the cost of conventional technologies.However, the technology requires a significant upgrade in terms of the sensor dynamic range and accuracy to be adopted universally by the network operators -- including circuits both outside and within the substation. While protection-grade measurements external to the substations are sufficient to implement hybrid or multi-ended circuit protection schemes, metering-grade or combined metering/protection-grade sensors are necessary to offer a holistic approach for extra- and intra-substation measurements. We estimate a 10-fold increase of the market share for Synaptec's solutions if the extended dynamic range challenge could be solved.Consequently, this project will develop an extend-range sensor based on a ground-breaking new concept of passively auto-ranging the photonic transducer. The concept has been patented and early proof-of-concept investigations indicate its great success; however, the technology requires significant development before it can be turned into a commercial offering.Therefore, the project consortium comprising Synaptec, University of Strathclyde and ITL will design and demonstrate a TRL6-7 distributed sensor system based on the auto-ranging concept. The innovation will involve ultra-low-power electronics to deliver passive auto-ranging functionality that is local to the sensors, together with extended-range current-to-voltage inductive converters, and an algorithm operating within the firmware of the central sensor interrogator to detect remote range changes and provide output scaling. The project will deliver a technology demonstrator that will be proven using Strathclyde's kA-level current injection facilities. The solution will compete on the measurement range and accuracy with nonconventional optical instrument transformers while offering an unprecedented level of multiplexing and geographical coverage, unachievable at this price point by any other technology. The project will significantly benefit and accelerate UK's transition to a sustainable energy economy.

随着英国向净零经济转型，电力系统的广域监控变得越来越重要。为了防止停电，需要高性能的分布式传感器来提供足够的实时数据，以实现电力系统的快速控制和保护。此外，由于不稳定的负载场景和新的极端天气，电网承受着前所未有的压力，因此需要对通常动态额定的电力线路和电缆进行广泛的状态监测。Synaptec 的分布式光子传感技术是应对这一挑战的理想解决方案，因为它搭载了电网预装光纤，并使用高性能无源传感器以经济高效的方式覆盖大面积地理区域，不需要建筑物、电源、通信基础设施或 GPS 信号。 Synaptec 的客户以传统技术成本的一小部分实施了新颖的控制或保护方案。但是，该技术需要在传感器动态范围和精度方面进行重大升级，才能被网络运营商普遍采用，包括外部电路以及变电站内。虽然变电站外部的保护级测量足以实施混合或多端电路保护方案，但计量级或组合计量/保护级传感器对于提供变电站外和变电站内测量的整体方法是必要的。我们预计，如果能够解决扩展动态范围的挑战，Synaptec 解决方案的市场份额将增加 10 倍。因此，该项目将开发一种基于被动自动调整光子范围的突破性新概念的扩展范围传感器。传感器。该概念已获得专利，早期的概念验证研究表明其取得了巨大成功；然而，该技术在转化为商业产品之前需要进行重大开发。因此，由 Synaptec、斯特拉斯克莱德大学和 ITL 组成的项目联盟将设计并演示基于自动测距概念的 TRL6-7 分布式传感器系统。该创新将涉及超低功耗电子设备，以提供传感器本地的无源自动量程功能，以及扩展范围的电流电压感应转换器，以及在中央传感器询问器的固件中运行的算法，以检测远程范围变化并提供输出缩放。该项目将提供一个技术演示器，该演示器将使用 Strathclyde 的 kA 级电流注入设施进行验证。该解决方案将在测量范围和精度方面与非传统光学仪器变压器竞争，同时提供前所未有的多路复用和地理覆盖水平，这是任何其他技术在这个价位上无法实现的。该项目将显着受益并加速英国向可持续能源经济的转型。
