Process Asset & Energy Management
As plants drive to improve efficiency and gain better understanding of their costs there is a renewed focus on energy management. A general strategy for energy management would include: monitoring, measuring and optimizing your process, assigning costs to your energy consumers and finding ways to improve their efficiency. It is not enough to look at your process asset management but you also need to include the energy efficiency of those devices in your methodology. Siemens PCS 7 approach is to integrate the process, asset and energy management data and provide you the transparency to make informed decisions. Your Advantage With Siemens
This information provides a better understanding of the plant's purchased power so that your can insure proper billing, reliability and quality to avoid upsets in the process. Now that the power has been supplied to the plant, you want to insure protection, distribution and sub-metering to understand consumption and internal billing and optimization. Reports can be generated which can help identify power quality, reliability, correlations between production and consumption to make informed decisions about what processes and applications you are running when. You can then use this information for manual or automated strategies to optimize your process using integrated power monitoring, adding drives to process applications, boiler optimization to more advanced strategies for process equipment optimization, load shedding and co-generation.
Examples of plant assets as it relates to the process automation system are:
Asset Maintenance Strategies
SIMATIC PCS 7 enables you to implement different maintenance strategies depending on whether a response to failures or preventive actions is required.
Corrective maintenance strategies are followed when a fault has occurred, for example failures occurred in this case are minimized by a redundant plant design.
Preventive strategies allow you to complete maintenance measures before faults occur, preventing unplanned downtimes
Preventive strategies can be implemented by the following three ways:
Time-based measures such as, regular maintenance activities
Condition-based measures which are initiated depending on the degree of wear
Predictive measures which can recognize problems early and provide the you with information on the remaining service
