METTLER TOLEDO (2018) Smart Alarms for Better Power Plant Monitoring

This video provides an overview of the role that analytical equipment can play in a power plant’s Smart Alarm system. It discusses Smart Alarms as a method to support technical teams in validating alarms, and managing labor resources to respond to the most critical alarms first. For more on Smart Alarms, download the white paper, Optimizing Alarm Management Through Qualified Input Parameters: https://www.mt.com/global/en/home/lib… Smart Alarms is an Alarm Management Guidance strategy that has been developed by industry standard organizations as a result of in depth research and knowledge gained from power plant management processes. Alarm Management Guidance is about providing better definition for alarm configuration, management and action plans through experience planning and technology. Smart Alarms, a key part of Alarm Management Guidance, uses technology, plant operation experiences and common failure analysis data to create Distributed Control System (DCS) logic that looks at possible causes for an alarm, and recommends actions that should be taken to help mitigate the alarm. A properly set up Smart Alarms system will use this logic to validate the alarms against other inputs. For example, if a reading from your pH sensor in the condensate stream begins dropping, the DCS can take that information and compare it to the calculated pH from a conductivity sensor connected to a METTLER TOLEDO M800 transmitter. If that pH calculation is not dropping, the Smart Alarm system could advise that you may have a problem with the pH sensor. As a next step, if you are using a pH sensor with Intelligent Sensor Management (ISM®) you can check predictive diagnostics such Adaptive Calibration Time (ACT) and Dynamic Lifetime Indicator (DLI) to verify that all you sensors are measuring accurately. Thus with ISM you receive alerts and clear guidance on actions to take if problems with your sensors arise. But, if the DCS finds that the calculated pH at the Conductivity sensor is also dropping, you may receive other guidance from the Smart Alarms system. The decision-tree logic set up as part of the Smart Alarms system is designed to help validate alarms and make sensor management easier.
