The symposium committee is pleased to announce that Bill Hollifield from PAS will be an invited speaker for the 2013 WWAC symposium. He will be presenting a talk about how using High Performance HMI (human machine interface) computer screens result in higher operator effectiveness and decrease chances of operator mistakes. Bill will be highlighting a recent EPRI (electric power research institute) study, with particular focus on how the study results can be applied to the water/wastewater sector. This is a follow-up to the talk Bill gave at WWAC2012 symposium about what High Performance HMIs are. Bill also recently published an article in ISA InTech magazine about high performance HMIs.
Bill Holllifield is a member of the ISA-18 Alarm Management committee, the ISA-101 HMI committee, the API-1167 Alarm Management committee, and is a co-author of the Electric Power Research Institute’s Alarm Management Guidelines. Bill is also co-author of The High Performance HMI Handbook.
High Performance HMI – Proof Testing in Real-World Trials
Speaker: Bill Hollifield, PAS
Almost all industrial processes are controlled by operators using dozens of graphic screens. The graphic designs are typically little more than P&IDs covered in hundreds of numbers. This traditional, “low performance” Human Machine Interface (HMI) paradigm is typical in all processes controlled by DCS and SCADA systems, including the water and wastewater sector. It has been shown to be lacking in providing operator situation awareness and in facilitating proper response to upsets. In many industries, poor HMIs have contributed to major accidents, including fatalities.
HMI improvement has become a hot topic. This talk will cover the basics of High Performance HMI, which provides for much improved situation awareness, improved surveillance and control, easier training, and verifiable cost savings.
Additionally, a major proof test of High Performance HMI concepts was carried out by the Electric Power Research Institute (EPRI) and PAS. The test involved a major power plant with a full-fidelity process simulator. Operators were put through various abnormal and hazardous situations using both the traditional graphics and new, high performance graphics. The details and very positive results from this thorough test can now be presented outside of the EPRI member companies, and are applicable to a wide range of processes.
