明确的行动建议

工厂能效管理系统(PEEMS)是横河电机深入研究、全方位考虑后的EEM解决方案,可根据工厂的能耗提供合适的解决方案。

上述图表清楚地表明横河电机解决方案的基本原理和架构,通过这些操作可以帮助客户提高EEM

然而,在过程工业中,确定和实现工厂的潜在成本削减有四个基本条件:
1.一个数据量庞大且合格的数据库
2.智能数据分析和说明
3.清晰可视化结果
4.明确且有意义的行动方案

所有相关能源流的概述

目的是通过评估原始数据尽可能自动推导出最合适的能源使用方案然后以结构化形式将这些方案传达给相关操作人员。这是一个优势,用熟悉的流程图像解决工厂操作员的问题,并为他们提供容易理解的能量流概览。为了这个目的需要一个其他的指标,类似于Sankey中的箭头。

在多级菜单中提供了详细的补充信息。直观的配色方案清晰的屏幕布局和简单的图标使关键分析结果能够快速准确地被理解吸收。对于负责横河新的工厂能效管理系统PEEMS)的研发团队来说,易理解是首要被考虑的。

专用信息过滤器

企业决定运行EEM系统时,必须同时考虑当工厂扩和复杂增加时,EEM系统的扩展性。在极端情况下,一个基于记录仪的小系统可以逐步发展为使用独立PLC进行控制,并最终引入过程控制系统。EEM过程的结构 - 通常是能量优化操作的最重要手段 - 保持完整无缺,因此需要有意识的保留和扩展这种技术。

EMM系统不是取代工厂操作员的自动操作仪。相反,一系列其他参数,例如安全性原材料质量、特殊产品质量、生产效率和生产能力要求的可用组合都有着至关重要的影响。该系统就像是操作员辅助工具,集成以下重要功能:
1.比较趋势和能量优化操作
2.向工厂操作员显示,切换到不同的操作模式能节省多少能量
3.必要的时候,帮助操作员完成从现有操作模式到优化操作模式的转换

为了圆满完成这些任务,需要满足几个条件:可靠、有意义的数据库对数据的结构和优先级的说明,清晰且易于理解的可视化结果以及推荐一个或多个行动方案。

除了满足这些要求,横河电机的EEM系统可以最大限度地提高效率和降低成本,同时最大限度地减少工厂操作员的额外负荷

ISA S88.01 provides great benefit to users and vendors by solidifying batch operating models and standardizing batch control terminology. On the other hand, as befits an industry-wide standard, ISA S88.01 leaves great flexibility for individual users to apply their own project practices and implementation methodology. Even when utilizing ISA S88.01 models and terminology, many pitfalls remain for those who implement batch controls and recipe management without thinking ahead. Real-world project experience has demonstrated a number of design and implementation "lessons" which might be overlooked to the eventual grief of the batch engineer.

概述:

The S88.02 draft standard defines a means for depicting procedural control in master and control recipes. This depiction method is called a Procedural Function Chart (PFC). This standard depiction is based on the requirements of S88.01, technical report ISA-TR88.0.03-1996, user requirements, previous standards and commonly used procedure depiction methods in use today. PFCs can provide a common basis for the exchange of recipes, reduce the learning curve between control systems, and establish a common ground for improved human communication. This paper provides a brief overview of the development of PFCs, the rules for their use and some of the benefits expected by their adoption in the industry.

概述:

The case study in this paper illustrates the value of integrating front-end scheduling with a batch control system. Recipe changes, and addition of recipes, occur frequently in the target process. However, since both scheduler and batch packages were designed with the ISA-S88.01 model in mind, these packages could be tightly coupled (well integrated) – and, as a result, it is easy to add or change recipes. The front- end scheduler is not limited to performing scheduling; it also provides an easy-to-grasp real-time production status display which can help enhance efficiency and productivity.

概述:

As batch processes are automated, it is common to leave certain less essential field devices without automatic actuators. Thus, the initial control design must accommodate both automated and manual activities. Later, the manual field devices may be automated, either one-at-a-time or in related groups as equipment modules. These field changes, often occurring over a period of years, each require rework of the batch control logic, which can easily exceed the cost of the actuator. In response to this undesirable situation, a technique has been developed which permits the batch design to automatically modify itself, or evolve, to accommodate changes in field automation.

概述:

Six Sigma is a quality improvement methodology applied to improving any type of process. It is a methodology endorsed by and heavily integrated into several major chemical companies.

概述:

Key Performance Indicators (KPIs) are used in batch processing industries as measurements of production performance. Their use is one element in the current trend of real-time performance management. A single KPI used as the primary measurement of production can cause other dimensions of production performance lose importance. When multiple KPIs are used to measure a batch's production performance it can be difficult to reconcile differences between them for individual batches or for groups of batches. KPIs based upon meeting a target, or specification, measure absolute performance yet do not provide relative information regarding how a batch performed against its peers. The peer comparisons are important for monitoring variability of production performance, which is a critical factor in documenting ROI.

概述:

The application of DCS-based "advanced controls" is a common method of achieving enhanced performance from continuous processes such as refinery units. However, it is less widely recognized, but nonetheless true, that modern DCS systems can include other software tools for the significant improvement of batch plant productivity, product quality, and economic performance. Due to the fundamental processing differences between the two types of plants, unique batch "advanced control" features are required which are different from those used for continuous plants.

概述:

ARC believes that by implementing procedural automation, many process plants can minimize variability to help ensure smooth, efficient, and safe state transitions.
