关于客户
NEM Energy bv 是全球发电和工业应用蒸汽发生设备领域的领先公司。该公司以独特的专业知识和持续的技术创新为动力,开发了太阳能蒸汽发电等新应用。他们的聚光太阳能 (CSP) 系统是一种可持续的能源,使用镜子或透镜将阳光集中到一个小区域,以驱动连接到发电机的热力发动机。
挑战
NEM Energy bv 的聚光太阳能发电 (CSP) 系统面临重大设计挑战。 CSP 系统使用镜子或透镜将阳光集中到一个小区域,以驱动连接到发电机的热机。关键的挑战是提高 CSP 镜子的刚度。这对于确保尽可能多的反射光被引导到目标(称为接收器)而不产生成本溢价至关重要。刚度至关重要,因为距离塔 380 米处的定日镜仅 1 度的旋转误差就会导致 6.6 米的跟踪误差,这意味着反射光从距离塔上的预定目标 6.6 米处传递。
解决方案
NEM Energy bv 利用 ANSYS® Mechanical™ 来应对设计挑战。该工程解决方案涉及使用壳(网格)元素对定日镜的 16 个镜面或面进行建模。 ANSYS Workbench™ 用于使用 5 毫米公差值自动添加 1,000 多个接触点。对模型的小部分进行塑性变形计算,以解释结构的永久变形。作为批处理过程的一部分,ANSYS 参数化设计语言 (APDL) 命令片段用于评估不同角度和风速下的模型。 APDL 命令片段的输出被导出到光线追踪例程,该例程确定结构变形对到达接收器的光的影响。然后,这些结果用于计算每个定日镜设计可以产生的潜在电量。

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.
