系统集成商和oem实现创业成功- Tesco Controls, Inc.-优德网页版

以下是系统集成商和oem在水/废水资本项目调试和启动阶段遇到的共同问题的解决方法.

Alan Horikawa, national service manager, and Scott Okasaki, Northern California field services manager, both of Tesco Controls, 最近为《优德网页版》杂志2019年8月号合写了一篇文章. The article is titled Systems Integrators And OEMs Achieve Startup Success. 这是一个摘要，点击上面的链接查看全文.

Water/wastewater capital projects, 无论是新的绿地开发或改造棕地事业, 在许多层次的承包商和供应商之间进行需求协调. 大多数现代项目都有电气控制和自动化元素, often provided by a control system integrator (SI), and the SI must work closely with many entities. Unfortunately, 典型的设计/投标/建造(DBB)项目组织层次结构会阻碍沟通.

堀川和冈崎指出了SIs面临的共同挑战.

重要的基础系统通常由原始设备制造商(OEMs)提供。, adding to the challenges. 这包括三种主要类型的原始设备制造商:电气设备供应商, 过程滑块供应商和自动化部件供应商.

In this article, they cover some strategies, 并展示SIs如何在调试和启动期间成功地与oem合作.

Theory versus Reality

In theory, most issues should be resolved before construction, 但在实践中，存在许多技术和范围差异的接口和机会, 其中一些可能会持续存在或在启动期间暴露出来. During startup, SIs are performing many tasks and time is of the essence, with SIs often operating under the motto “last in, first out”.

Automation Commissioning and Startup Basics

Although projects use varying terminology, 在本文中，调试涉及基本的信号验证, while startup refers to functionally operating equipment. 理想情况下，大部分设计都是通过工厂验收测试过程进行预测试, 但作者描述了各种自动化平台如何只能与现场的实际信号完全集成.

输入/输出信号，无论是硬连接的还是现场总线的，必须进行测试并记录. 这涉及到SI、电气承包商和受影响的OEM供应商. 然后进行功能检查，每个团队都必须在内部测试他们自己的区域, and then perform integrated testing with each other.

Engaging Electrical OEMs

因为确保足够和安全的电力是任何启动工作的基础, 电气设备制造商通常是SI第一个委托来检查开关设备的人, generators, motor controls, and other elements. Usually this involves monitoring these systems, 但有时需要测试更复杂的自动化和联锁.

Integrating Process Skids

在电力公用事业已经证明，过程滑集成是下一步. Process skids take many forms. They may ship complete or require field assembly, may be provided with on-board controls, 或者可以作为需要现场自动化的裸设备采购. 堀川和冈崎说，这增加了并发症.

Process skids, however, 更有可能有广泛的自动化需求, each of which affect overall performance. This includes sequencing for events like backwashes, 根据需求循环使用紫外线系统等设备, timing of trains within a unit, 连续调节控制的调整，如化学注射, and other process operations. 当process skids带着他们自己的控制包到达时，可能会有一个简单的启用/禁用接口通过硬连线连接暴露给主自动化系统. But even in this case, 打滑也可能需要确定操作参数, set and tested.

At this point, the SI is focusing not only on specific equipment, 但可能是解决自动化设计或控制平台的核心问题.

Automation OEM Issues

SIs必须善于使用各种自动化硬件, software, networking, and field instrumentation products and issues. 作者确定了许多必须执行的常见任务. 每个活动都需要测试过程和文档来提供完整的结果并支持有效的问题解决.

So, if any one thing, small or large, fails to work as planned, it may be difficult to identify the root cause. 最好的项目是避免推卸责任，而是采用基于团队的解决问题的方法. 建立这种积极的文化，以执行工作和解决不可避免的挑战，必须由业主和总承包商领导, with the proper degree of autonomy granted to the SI.

当将多个OEM系统集成为一个整体时，SI的独特定位可以发现并帮助解决任何问题, helping the entire team achieve startup success.
