The plant operator has an extremely valuable and important responsibility: being the force and energy managing a capital enterprise easily worth hundreds of millions of dollars to produce or impact a daily revenue stream of millions, give or take. We ask him to be ever mindful of what the plant might be doing. We ask him to be capable of finding every little problem before it grows into a big one. We ask him to shoulder the burden of everything that goes wrong during his watch, all without any recognition when nothing does, and precious little (if not actual blame) when it goes wrong and he manages to manage. Within his area of responsibility and authority he must be able to view every control loop, most sensors, most pieces of equipment, and much of the supporting utilities, and then adjust as appropriate.
The failure to maintain situational awareness has been present in almost every disaster event that was not the result of spontaneous complete surprise. Start with the assumption that no one wants an accident. That no one would chose disaster over success. But accidents and disasters happen. We now know to a high degree of certainty that they happen because those in charge of ensuring that they do not happen, aren't aware that they are happening. They fail to know the situation. They are unaware of what is really going on, what is likely to happen, or what isn't happening that they think is. As explained in my book Alarm Management for Process Control, the solution is facilitated by effective operator interface design. Let's follow the path of interface design that can lead to better situation awareness.07/08/2009

Starting a power-generating unit involves bringing a plant from shutdown conditions to synchronization between the electrical generator and the transmission network or grid. Optimizing this process requires a careful balance which minimizes startup energy costs and limits plant damage. Traditionally, the startup of a coal-fired unit is performed manually by highly skilled operators. For RWE npower, however, an analysis of the startup methodology using the PI System from OSIsoft revealed significant variation in the company's techniques. Having identified the reasons for the variations, RWE npower then standardized and optimized the procedures to ensure that best practices were achieved for every startup.06/01/2009
As with most electric transmission and distribution (T&D) companies, growth does not come without many challenges commonly faced by most large utility companies: diverse data sources in different locations with restricted access; numerous manual data retrieval processes with limited ability for people outside the control center to immediately observe what problems have occurred; and operating in an interactive environment.
In 2003, one T&D utility implemented OSIsoft's PI System (PI) across all transmission and distribution operations. This decision dramatically changed the way the utility was able to access power system data and conduct business. Now operators, engineers, analysts, managers and executives are able to monitor real-time power system data using easy-to-configure displays with the ability to trend and analyze in real time or historical mode. PI gave the utility the ability to monitor transmission line status from the Emergency Operations Center when crises arise. Systems are now integrated, and data is provided to operations, management, planning, forecasting and regulatory compliance groups.06/01/2009
Westar Energy Inc. turned to WiredCitys IT Monitor as its primary means of preventing network and system problems inside its power plant network. The decision was spurred on by Westar Energy's familiarity and satisfaction with WiredCitys parent company, OSIsoft Inc., whose Real-time Performance Management (RtPM) Platform has had a successful track record in Westar Energy's power generation plants. In addition to improving the quality of network service and ensuring that power traders maintain critical Internet connectivity, Westar Energy discovered new uses for IT Monitor, including tracking down a virus and tuning an Oracle database, which saved a potentially costly upgrade.06/01/2009
Surface Acoustic Wave Technology-Based Temperature Monitoring of High Voltage and High Current Switchgear Boxes
Safety is a big concern when it comes to managing power distribution systems. High voltage and high current switchgear boxes serve an important role in establishing points of control within the power distribution system. The high voltages and current flowing through switchgear boxes greatly increase the probability of electric arcing and arc blasts. An arc blast is characterized by intense amounts of heat, pressure, shrapnel and molten copper. Great strides have been made in building arc resistant switchgears, nevertheless accidents have happened and the state of technology is far from completely eliminating them. One solution to this problem is to monitor the temperature of switchgear boxes to elicit early warning signs of imminent failure. Conventional methods of monitoring switchgear temperature are expensive and not entirely effective. Surface Acoustic Wave (SAW) technology can provide a passively powered (battery-less), wireless temperature measurement solution that is suited for switchgears. This application note explores how a SAW based solution can provide a reliable, safe and cost-effective means of monitoring switchgear temperature.05/27/2009
Until a few years ago, QNIs cobalt/nickel refinery in Yabulu, Australia, used manual process-recording methods. Process engineers found it difficult to determine the influence of variables on product quality and to generate timely reports for management. Management was frustrated by the challenges of accounting for monthly reconciled recovery, determining where losses occurred and tracking quality by batch.
To gain control over its operations and processes, QNI needed to track key performance indicators (KPIs) and overall equipment effectiveness (OEE). Though QNI already had a functioning ABB distributed control system, it couldnt store process data for more than three weeks not really long enough to track production records and monitor KPIs. Faced with ISO 9001 compliance and the need to implement Six Sigma in its manufacture of high-grade nickel and cobalt products, QNI chose OSIsofts solution to combine production data from its six business units with their total of eight separate control rooms.05/22/2009

The Kodak Park, located in Rochester, N.Y., is over 100 years old. The site has 1300 acres, two utility power plants, two company-owned water and waste water treatment plants, 150 buildings and 11,000 employees. The Kodak Park utility power plants have enormous generation output and demand requirements including 2,000,000 pounds per hour steam load and a 125 MW electric load.
The site also has 600 electric distribution meters, 600 additional non-electric distribution meters and many generation site meters. The utilities systems were operated and monitored by a group of disparate building automation systems and distributed control systems.
With such a vast energy and management system, Kodak shares many of the same concerns as regional utility companies conservation, optimization of resources and consolidation of data from various legacy systems. Any new technology solution added to this mix had to be compatible with our well-defined information architecture requirements.05/01/2009
Formed in 2001 as the result of a government initiative to create competitive subsidiaries in the power generation industry, Korea Hydro & Nuclear Power Company (KHNP) needed to monitor different variables at its multiple nuclear power facilities. KHNP also wanted to actively manage the changing business conditions in Korea. There was increasing public and government concern about safety and the environmental impact of nuclear power. Residents in the towns surrounding the plants were demanding greater transparency of operations and systems. Additional requirements were to enhance the efficiency of information between facilities and integrate plant data with the companys SAP Enterprise Resource Planning system. To solve information access and transparency problems, KNHP chose the PI System from OSIsoft.05/01/2009
As industrial Ethernet networks grow in number and importance, keeping the right traffic on and off the network becomes essential
The use of Ethernet for industrial automation has grown dramatically. One of the main benefits of moving from legacy fieldbus to Ethernet is the ability to connect the front office to the manufacturing system. This is possible because Ethernet is not a proprietary communication protocol. The non-proprietary nature of Ethernet allows engineers to mix and match equipment from different vendors and get competitive bids. This combination of better office-factory communication and open standards helped industrial Ethernet gain recent widespread acceptance.
But with these benefits come potential problems. As networks and the services they provide evolve and servers or user machines are replaced and upgraded, the likelihood of passing unwanted, often obsolete protocols within the network increases.
Potentially more challenging is the existence of unknown protocols that may degrade the performance of the network. Unknown protocols are often caused by well-intended but uninformed employees who attach unauthorized devices, such as wireless access points, to the network. They can also be caused by traffic such as streaming audio from employees listening to Internet radio stations while working.04/28/2009
In 2000, Innovenes Sarralbe, France plant updated its antiquated legacy system infrastructure with the OSIsoft PI System to provide real-time and historical information. Next, the company wanted to increase operational and development efficiencies. They sought to avoid multiple manual inputs and to minimize custom application development.
In 2004, the Innovene, Sarralbe site implemented OSIsofts Analysis Framework (AF) for faster application configuration to help employees analyze and optimize processes more efficiently.
