挑战
项目大学长期以来一直在努力提高校园建筑和设施的整体能源效率。为了提高电能效率，大学采用了更经济的照明系统、高效电机、楼宇管理系统和其他措施。然而，有一个几乎完全被忽视的电能节约领域——通过优化校园配电电压可以实现的节能。与全国许多大学一样，默里州立大学 (MSU) 一直致力于提高校园的能源效率。 MSU 占地 236 英亩的主校区位于肯塔基州默里市，该市约有 18,000 名居民。该大学成立于 1922 年，已从 202 名学生发展到今天的 10,400 名学生。大学从市政拥有的田纳西河谷管理局 (TVA) 配电公司 Murray Electric System (MES) 购买所有电力。 2011 年 3 月，Utilidata 在默里州立大学校园部署了其 AdaptiVolt™ 电压优化软件。获得专利的 AdaptiVolt™ 软件已安装在美国和加拿大的主要电力公司和工业设施中，在实施节能降压时可显着节省能源。

解决方案
MSU 主变电站由 Murray Electric System 的两条 69 kV 子输电线路供电。每条 69 kV 线路都为一个三相变压器供电，它们都配备了 ±16 步的有载分接开关 (OLTC)。任何时候只有一台变压器为校园供电，另一台作为备用。这些馈线上的负载包括从小马力到 1500 马力的感应电机、变频驱动器、照明、HVAC、楼宇控制以及其他典型的大学校园设施和居住负载。 AdaptiVolt™ 系统安装在变电站的控制柜中，远程访问控制台安装在 MSU 电气车间。作为新能源管理系统 (EMS) 的一部分安装的 22 个电力监视器通过校园的以太网系统向 EMS 和电压提供 AdaptiVolt™ 的信息。此外，在变电站安装了两个收入级电力监视器，用于电力和能源测量，两个具有光纤通信能力的新数字 OLTC 控制器取代了原来的机电控制器。 AdaptiVolt™ 软件连接到电力计量系统以获取电压读数，然后向 OLTC 发出控制命令以调节变电站中的电压。 MSU 工程师和当地电力公司运营商可以通过操作员界面终端全面了解和控制系统。

IoT Solutions for Smart City | Internet of Things Case Study
There were several challenges faced: It is challenging to build an appliance that can withstand a wide range of voltage fluctuations from as low at 90v to as high as 320v. Since the device would be installed in remote locations, its resilience was of paramount importance. The device would have to deal with poor network coverage and have the ability to store and re-transmit data if networks were not available, which is often the case in rural India. The device could store up to 30 days of data.

Automation of the Oguz-Gabala-Baku water pipeline, Azerbaijan
The Oguz-Gabala-Baku water pipeline project dates back to plans from the 1970’s. Baku’s growth was historically driven by the booming oil industry and required the import of drinking water from outside of the city. Before the construction of the pipeline, some 60 percent of the city’s households received water for only a few hours daily. After completion of the project, 75 percent of the two million Baku residents are now served around the clock with potable water, based on World Health Organization (WHO) standards. The 262-kilometer pipeline requires no pumping station, but uses the altitude differences between the Caucasian mountains and the capital to supply 432,000 m³/d to the Ceyranbatan water reservoir. To the people of Baku, the pipeline is “the most important project not only in 2010, but of the last 20 years.”

GPRS Mobile Network for Smart Metering
Around the world, the electricity supply industry is turning to ‘smart’ meters to lower costs, reduce emissions and improve the management of customer supplies. Smart meters collect detailed consumption information and using this feedback consumers can better understand their energy usage which in turn enables them to modify their consumption to save money and help to cut carbon emissions. A smart meter can be defined in many ways, but generally includes an element of two-way communication between the household meter and the utility provider to efficiently collect detailed energy usage data. Some implementations include consumer feedback beyond the energy bill to include online web data, SMS text messages or an information display in consumers’ premises. Providing a cost-effective, reliable communications mechanism is one of the most challenging aspects of a smart meter implementation. In New Zealand, the utilities have embraced smart metering and designed cost effective ways for it to be implemented. The New Zealand government has encouraged such a move to smart metering by ensuring the energy legislation is consistent with the delivery of benefits to the consumer while allowing innovation in this area. On the ground, AMS is a leader in the deployment of smart metering and associated services. Several of New Zealand’s energy retailers were looking for smart metering services for their residential and small business customers which will eventually account for over 500,000 meters when the multi-year national deployment program is concluded. To respond to these requirements, AMS needed to put together a solution that included data communications between each meter and the central data collection point and the solution proposed by Vodafone satisfied that requirement.

NB-IoT connected smart meters to improve gas metering in Shenzhen
Shenzhen Gas has a large fleet of existing gas meters, which are installed in a variety of hard to reach locations, such as indoors and underground, meaning that existing communications networks have struggled to maintain connectivity with all meters. The meter success rate is low, data transmissions are so far unstable and power consumption is too high. Against this background, Shenzhen Gas, China Telecom, Huawei, and Goldcard have jointly trialed NB-IoT gas meters to try and solve some of the challenges that the industry faces with today’s smart gas meters.

British Gas Modernizes its Operations with Innovative Smart Metering Deployment
The UK government has mandated that smart meters are rolled out as standard across Great Britain by end of 2020, and this roll-out is estimated to create £14 billion in net benefits to the UK in consumer energy savings and lower energy generation demand, according to the Oxford Economics report, “The Value of Smart Metering to Great Britain.” While smart-metering systems have been deployed in many countries, the roll-out in Great Britain is unique because it is led by energy retailers, who have responsibility for the Electricity and Gas meters. The decision to have a retailer-led roll out was made by DECC (Department of Energy and Climate Change) to improve customer experience and drive consumer benefits. It has also led to some unique system-level requirements to support the unique local regulatory model.
