关于客户
本案例研究中的客户是加拿大航天局 (CSA),这是一个政府机构,负责加拿大所有民用太空相关活动,包括加拿大对国际太空计划和伙伴关系的贡献。 CSA 旨在通过科学推进太空知识,并确保太空科学和技术为加拿大人带来社会和经济效益。 CSA 是一位经验丰富的客户,对空间技术以及与设计和测试流动站原型相关的挑战有着深入的了解。他们正在寻找一种解决方案,可以减少总体开发时间,并允许在危险场景下进行组件测试,而不会有损坏整个流动站原型的风险。
挑战
在航天工业中,流动站原型的设计、建造和测试是一个昂贵且耗时的过程。系统测试通常要到设计/测试过程的后期才进行,从而导致开发时间较长。面临的挑战是在完整的流动站原型可用之前找到一种在模拟循环中测试组件的方法。这将为被测组件创建一个虚拟测试环境,欺骗它认为它正在完整的原型中运行。目标是在硬件组件可用时逐步将其添加到仿真循环中,即使没有所有硬件组件也可以进行系统测试,从而缩小设计和测试阶段之间的差距。
解决方案
滑铁卢大学的 Amir Khajepour 博士和他的团队与加拿大航天局 (CSA) 和 Maplesoft 合作,使用 MapleSim 开发了太阳能行星漫游车的硬件在环 (HIL) 测试平台。建模和仿真工具。该平台允许模拟在实验室设置中难以复制的场景,例如火星环境或尚不可用的组件。 MapleSim 建模环境还用于自动生成流动站的运动学方程,为项目中的其他任务(例如 HIL 仿真、路径规划和功率优化)奠定基础。在 MapleSim 中开发了一个流动站组件库,并在 LabView Real-Time 中导入,其中开发了模拟的 HIL 程序和 GUI。

Vestas: Turning Climate into Capital with Big Data
Making wind a reliable source of energy depends greatly on the placement of the wind turbines used to produce electricity. Turbulence is a significant factor as it strains turbine components, making them more likely to fail. Vestas wanted to pinpoint the optimal location for wind turbines to maximize power generation and reduce energy costs.

Siemens Wind Power
Wind provides clean, renewable energy. The core concept is simple: wind turbines spin blades to generate power. However, today's systems are anything but simple. Modern wind turbines have blades that sweep a 120 meter circle, cost more than 1 million dollars and generate multiple megawatts of power. Each turbine may include up to 1,000 sensors and actuators – integrating strain gages, bearing monitors and power conditioning technology. The turbine can control blade speed and power generation by altering the blade pitch and power extraction. Controlling the turbine is a sophisticated job requiring many cooperating processors closing high-speed loops and implementing intelligent monitoring and optimization algorithms. But the real challenge is integrating these turbines so that they work together. A wind farm may include hundreds of turbines. They are often installed in difficult-to-access locations at sea. The farm must implement a fundamentally and truly distributed control system. Like all power systems, the goal of the farm is to match generation to load. A farm with hundreds of turbines must optimize that load by balancing the loading and generation across a wide geography. Wind, of course, is dynamic. Almost every picture of a wind farm shows a calm sea and a setting sun. But things get challenging when a storm goes through the wind farm. In a storm, the control system must decide how to take energy out of gusts to generate constant power. It must intelligently balance load across many turbines. And a critical consideration is the loading and potential damage to a half-billion-dollar installed asset. This is no environment for a slow or undependable control system. Reliability and performance are crucial.

Remote Monitoring and Control for a Windmill Generator
As concerns over global warming continue to grow, green technologies are becoming increasingly popular. Wind turbine companies provide an excellent alternative to burning fossil fuels by harnessing kinetic energy from the wind and converting it into electricity. A typical wind farm may include over 80 wind turbines so efficient and reliable networks to manage and control these installations are imperative. Each wind turbine includes a generator and a variety of serial components such as a water cooler, high voltage transformer, ultrasonic wind sensors, yaw gear, blade bearing, pitch cylinder, and hub controller. All of these components are controlled by a PLC and communicate with the ground host. Due to the total integration of these devices into an Ethernet network, one of our customers in the wind turbine industry needed a serial-to-Ethernet solution that can operate reliably for years without interruption.

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.
