ActivePoint HMI (Human Machine Interface) To improve worker efficiency, reduce operating costs, and deliver a superior power plant user experience, GE engineered the ActivePoint HMI in close collaboration with more than 100 operators globally. The ActvePoint HMI is in compliance with ISA 18.2, the High Performance HMI Handbook, and other industry standards. It is a total solution enabling system monitoring and controlling from any device, anytime, anywhere. HMI screens for all GE power generation equipment will conform to this new design guideline to provide a common interface across the entire plant and to create a user experience that is visually appealing and enhances situational awareness.


Alarm and Protection Rationalization GE’s new alarm management system is fully integrated into the ActivePoint HMI. Alarms are now directly represented and actionable within both HMI screens and dedicated lists, and are based on GE’s three-step alarm rationalization process (Design, Categorization, and Alarm Prioritization). By applying common philosophies and rationalization rules across all equipment within the plant, enunciated items are categorized as Events, Diagnostics, Alerts, or Alarms (levels 1, 2, and 3) to greatly improve operator responsiveness.


Actionable alarms can be reduced by as much as 80 percent and are organized into parent-child hierarchies to simplify determining root causes. The alarm management system details the urgency, consequences, potential causes, and suggested actions. Using the Mark VIe distributed control system (DCS) for controlling the entire plant enables enhanced alarm configuration and presentation capability, as well as an integrated operating experience across GE equipment.


Similar to alarm rationalization, GE developed a consistent process for rationalizing the controls protection system associated with plant equipment (Trips, Shutdowns, Runbacks, Pre-Start Checks, and Permissives). Trip optimization reduces or eliminates nuisance trips. Startups are streamlined through the categorization of pre-start checks (not required for startup) and permissives (required for startup).
