节能降压是在允许水平的较低电压范围内操作配电系统的做法，从而提高许多电力利用设备（例如感应和同步电机、变压器、照明系统等）的效率。这种方法可以应用于各种工业环境；但是，使用 AdaptiVolt™ 等先进的实时控制系统对于确保电压不会下降到使重要过程面临风险的水平至关重要。 AdaptiVolt™ 实时监控整个设施的电压并做出控制决策以安全地降低电压，从而在保持过程可靠性的同时实现能源效率提升
Plum Creek Timber Company 是美国最大、地理上最多样化的私人土地所有者，在美国主要木材产区占地约 700 万英亩。该公司生产木材和其他木制品
2008 年 9 月，Utilidata 在蒙大拿州哥伦比亚瀑布市的 Plum Creek Timber 中密度纤维板 (MDF) 工厂部署了 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。在以前的部署中实施保护电压降低时，AdaptiVolt™ 软件提供了显着的节能效果。实时电压监测和 Utilidata 的专利算法使系统能够在具有不同工业流程的设施中运行，同时节省成本并提高可靠性。 Plum Creek 的 MDF 设施有两条生产线：工艺线#1 和工艺线#2。每条生产线都有由大马力（10,000+ hp）同步电机驱动的大型精炼机，每台都直接连接到来自配电变电站的三个 13.8 kV 馈线之一。每条生产线还有另一个直接连接到变电站的馈线，为过程的平衡提供动力，包括用于轧制、压制、材料处理和环境调节的电机。为 MDF 设施供电的五个电路中的每一个都在变电站由三相电压调节器单独控制。 Plum Creek 安装了一个电能计量子系统来为该项目收集电压。变电站的每个电路都安装了电表；安装在每台同步电机上；并且，安装在整个设施的 27 个其他位置。 AdaptiVolt™ 软件连接到电力计量系统以获取电压读数，然后向变电站中的电压调节器发出控制命令。 Plum Creek 工程师和当地电力公司运营商可以通过 SCADA 用户界面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.
OneWireless Enabled Performance Guarantee Test
Tata Power's power generation equipment OEMs (M/s BHEL) is required to provide all of the instrumentation and measurement devices for conducting performance guarantee and performance evaluation tests. M/s BHEL faced a number of specific challenges in conducting PG tests: employing high-accuracy digital communications for instrumentation, shortening setup and dismantling time, reducing hardware required, making portable instrument setup, avoiding temporary cabling work and the material waste costs
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.
