Digital voltage and current sensors for an intelligent grid

该项目是不列颠哥伦比亚省政府能源与矿业部、不列颠哥伦比亚省理工学院（BCIT）和总部位于温哥华的NuGrid电力公司（NuGrid）之间的合作项目，旨在开发具有直接数字输出的光学中压（>1000 V和<100 kV）电流和电压传感器，以提供电网上的主动测量和实时测量通信。今天，配电网是相当被动的控制，没有任何实时测量的馈线。使用模拟仪表变压器和独立通信系统的混合系统具有显著的成本、安全性和安装挑战，使得它们对于变电站外部的电网的广泛仪表来说不切实际。光学传感器承诺增强的安全性，紧凑性和与传感器电子设备的集成通信，使其成为变电站外部（和内部）电网仪表的理想选择。NuGrid Power Corp（NuGrid）专注于为配电网（中压1 kV至<100 kV范围）开发具有成本效益的光学电压和电流传感技术。NuGrid的创始人在为输电网（100 kV至800 kV电压等级）开发光学传感器解决方案方面有着良好的记录。该项目将包括智能电网25 kV级电压（可能还有电流）传感器的开发、测试和认证。BCIT是加拿大智能电网系统和技术的应用研究领导者。BCIT在智能电网技术开发和认证方面进行了大量投资，包括RTDS系统（真实的时间数字仿真系统）和一些先进的数字控制器和智能电子设备。BCIT还成功完成了一系列重要的智能电网计划，包括微电网系统，以及电动汽车充电站的太阳能/电池能源管理系统。该项目将利用BCIT在先进电网技术方面的数百万美元投资，为智能电网开发、测试和鉴定光学传感技术。

This project is a collaborative effort between Government of British Columbia's Ministry of Energy & Mines, British Columbia Institute of Technology (BCIT) and Vancouver based NuGrid power Corp (NuGrid) for the development of optical medium-voltage (>1000 V and <100kV) current and voltage sensors with direct digital output to provide active measurement and real-time communication of measurements on the electric power grid. Today, the distribution grid is fairly passively controlled without any real-time measurement on the feeder lines. Hybrid systems using analog instrument transformers and separate communication system have significant cost, safety, and installation challenges, making them impractical for wide-spread instrumentation of the grid outside the substations. Optical sensors promise enhanced safety, compactness, and integrated communication with sensor electronics making them ideal for instrumenting the grid outside (and inside) the electric power substations. NuGrid Power Corp (NuGrid) is focused on developing cost-effective optical voltage and current sensing technology for the distribution grid (medium voltage 1 kV to <100 kV range). The founders of NuGrid have a strong track record in developing optical sensor solutions for the transmission grid (100 kV to 800 kV voltage level). The project will include development, testing and qualification of 25kV class voltage (and possibly current) sensors for Smart Grid. BCIT is an applied research leader in Canada in Smart Grid system and technologies. BCIT has made significant investment in smart grid technology development and qualification, including an RTDS system (Real Time Digital Simulation system) and a number of advanced digital controllers and Intelligent Electronic Device. BCIT has also successfully completed a number of significant smart grid initiatives, including a microgrid system, as well as a solar/battery energy management system for Electric Vehicle charging stations. The project will leverage millions of dollars of investment in advanced power grid technology at BCIT to develop, test and qualify optical sensing technologies for Smart Grid.
