关于客户
Connecticut Reserve Technologies, LLC (CRT) 是一家位于美国的工程咨询公司。他们专注于分布式电力系统的开发，特别关注用于紧凑型热电联产机组的微型涡轮机。这些装置旨在为制造工厂和其他设施提供现场电力，为公用事业线路提供经济可靠的替代方案。 CRT 的工作通常涉及使用先进的结构陶瓷，例如氮化硅，它允许微型涡轮机在比传统金属合金更高的温度下运行。这可以显着节省燃料并减少排放。 CRT 的工作通常在美国能源部的分布式能源计划下进行。
挑战
康涅狄格储备技术公司 (CRT) 在开发用于紧凑型热电联产机组的微型涡轮机时面临着重大挑战。这些装置旨在为制造工厂和其他设施提供经济可靠的电力，依赖于氮化硅等先进结构陶瓷。虽然这些陶瓷允许微型涡轮机在比传统金属合金更高的温度下运行，从而显着节省燃料和减少排放，但它们的断裂强度也表现出很大的变化。当考虑到各种表面处理造成的固有缺陷时尤其如此。面临的挑战是考虑这些复杂的统计强度分布，以便更准确地预测预期部件寿命。另一个挑战是定义和实施一种方法，根据特定组件为氮化硅供应商建立威布尔分布指标。这需要将转子叶片的各种处理表面的使用应力状态与规定的部件可靠性相结合，以制定材料性能曲线。
解决方案
CRT 利用 ANSYS Structural 分析软件来应对这些挑战。通过使用 ANSYS 参数化设计语言 (APDL)，可以识别具有指定表面处理的转子部件表面，查询 ANSYS 结果文件，并将应力映射到相关单元表面。然后使用 CRT WeibPar 算法分析故障数据。 CARES 算法使用 ANSYS 生成的信息（几何形状和应力状态）计算组件可靠性。 ANSYS 技术的开放性以及与其他软件集成的便利性使得 ANSYS、CARES 和 WeibPar 程序能够以平稳高效的方式协同运行。该解决方案允许开发可缩放至标准陶瓷弯杆测试样本的材料性能曲线，从而使材料供应商更容易理解组件要求。

Case Study
Hydro One Leads the Way In Smart Meter Development
In 2010, Ontario’s energy board mandated that time-of-use (TOU) pricing for consumers be available for all consumers on a regulated price plan. To meet this requirement, Hydro One needed to quickly deploy a smart meter and intelligent communications network solution to meet the provincial government’s requirement at a low cost. The network needed to cover Hydro One’s expansive service territory, which has a land mass twice the size of Texas, and its customers live in a mix of urban, rural, and remote areas, some places only accessible by air, rail, boat or snowmobile. Most importantly, the network needed to enable future enterprise-wide business efficiencies, modernization of distribution infrastructure and enhanced customer service. To meet these needs, Hydro One conceptualized an end-to-end solution leveraging open standards and Internet Protocols (IP) at all communication levels. The utility drew upon industry leaders like Trilliant to realize this vision.

Selling more with Whirlpool
Whirlpool wanted to add connectivity to appliances and transform the company's relationship with customers. Traditionally, Whirlpool interaction with customers was limited to purchases made once every ten years. Connected washer and dryers provide exciting new features like remote management of start times and inter-machine communication.

SAS® Analytics for IoT: Smart Grid
Companies face falling revenues, rising infrastructure costs, and increasing risk of outages caused by inconsistent energy production from renewable sources. Less money is coming in as more people and organizations take steps to curb their energy use. Utilities are paying more to maintain and build infrastructure due to increasing complexity, resulting from the rising number of intermittent and variable renewable energy sources connected in the distribution grid.

Enel Secures Italian Power Generation Network
Electric energy operators around the world are working to increase the reliability and cyber resiliency of their systems. This includes Enel, a global power company that manages and monitors the Italian power grid. This grid:• Serves 31 million customers• Has a net installed energy capacity exceeding 31 gigawatts• Includes more than 500 power generation plants,including hydroelectric, thermoelectric, and wind• Is managed and monitored by Enel 24/7/365• Is operated by Terna, the Italian Transmission System Operator (TSO)Enel is responsible for the availability of the grid’s underlying ICS and industrial network. It also manages Regional Control Centers and Interconnection Centers which connect with the TSO. The TSO manages the flow of energy to the grid plus controls and remotely regulates the power generation of power plants, increasing and decreasing power production as required. The complex system of interaction and cooperation between Enel and the TSO has strong security implications as well as operational and business challenges.

IoT based Energy Quality Availability Monitoring Solution
There were several challenges faced:Since this data would be in the public domain, accuracy and authenticity of this data were of paramount importance. It should be able to withstand scrutiny.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.The platform that deals with the data should be readily available and highly reliable and never lose a packet of data.
