We describe a work domain analysis of a hydropower plant that operates in the two independent markets, the electricity market and the irrigation market. Based on the results of a work domain analysis, the authors develop configural displays that represent abstract functions of the hydropower system and that are intended as part of an ecological interface.(More)
We discuss the human role in hydropower system control, noting how it is different from other supervisory control environments and noting the typical shortcomings in current displays provided to hydropower system controllers. We describe steps towards evaluating proposed functional displays with industry hydropower controllers whose time with us was limited(More)
We present a simulator of a hydropower company’s view of its scheme, and its broader market and network context, which has been developed to evaluate advanced displays for control room operations. Although simplified, the simulator captures all the main aspects of scheme operations. The simulator allows controlled studies to be performed that test the(More)
Much electrical generation in the developed world is now conducted within deregulated energy markets, providing new layers of uncertainty for human controllers and new challenges for analysts wishing to understand and support cognitive work. In this paper we outline some of the challenges encountered when attempting to describe the work domain of(More)
We present the design process of a highly portable integrated power system simulator developed to support investigation into human interface design for a complex hydro power system. The most important development phases of the simulator are described followed by insights that guided developers to the final version. The architecture of the simulator is(More)
This paper presents part of a project aimed at evaluating ecological interfaces in a real world complex system –a hydropower system. We investigate whether an advanced measurement method—here called the control adaptation method (CAM)—can be extended to evaluate how effectively a human operator is coupled to a complex process control environment. So far the(More)
This paper discusses the temporal fit of teams of controllers to a real world hydropower system (HPS) in a deregulated market environment, emphasizing how well displays support quality of control performance by industry controllers. The results of an empirical evaluation suggest that displays that integrate task constraints over appropriate time scales help(More)
We present the design rationale and basic workings of a low-cost, easy-to-use power system simulator developed to support investigations into human interface design for a hydropower plant. The power system simulator is based on three important components: models of power system components, a data repository, and human interface elements. Dynamic Data(More)
