Advanced Monitoring Advanced Monitoring provides intuitive, intelligent, and integrated real-time monitoring via a state-of-the-art interface. Energy Accounting Energy Accounting provides detailed energy consumption and cost analysis. Reports are generated based on energy tariffs and electrical power market exchange information. Real-Time Simulation Real-Time Simulation is a powerful set of analytical modules that allows the prediction of system behavior in response to operator actions and events using real-time and archived data. Event Playback Event Playback is especially useful for root cause and effect investigations, improvement of system operations, exploration of alternative actions, and replay of What If scenarios. Load Forecasting Load Forecasting reliably predicts and trends system loading based on algorithms that adaptively correlate multiple input variables such as weather conditions as part of an accurate load forecast. Automatic Generation Control Automatic Generation Control is a multi-area supervisory control that utilizes real-time data to regulate generation levels in order to maintain system frequency and power exchanges with neighboring areas at scheduled values. Economic Dispatch Economic Dispatch allocates changing generation demand of a power system amongst controllable generator units to achieve optimum area economy. Supervisory Control Supervisory Control performs steady-state real-time optimization allowing energy consumers to automate the operation of their power system, reduce system losses, and reduce peak load consumption. Energy producers can improve power exchange and maximize security.

    Load Shedding Substation Automation Intelligent Load Shedding (ILS) is the smartest and fastest proven method of its kind on the market. ILS provides optimal, fast load shedding based on actual operating condition of the system including type and location of the disturbances. ILS dynamically determines the best load shedding priority in a fraction of a second. Intelligent Substation (iSub) is a state-of-the-art management application packaged as a focused product for substation automation. iSub provides protection, control, automation, monitoring, and communication capabilities as a part of a comprehensive substation solution. Load Preservation Load Preservation first calculates the minimum required power to be shed for each subsystem and accordingly selects the optimal combination of loads that will satisfy the requirements. Load Restoration Load Restoration monitors system operating conditions after a load shedding event and restores loads while maintaining system stability and reliability. Load Shedding Validation Load Shedding Validation evaluates and confirms load shedding decisions in real-time mode. ILS integrates with the ETAP Transient Stability Analysis module to simulate and verify the load shedding requirements and recommendations before system commissioning. Substation Automation Substation Automation utilizes intelligent analysis processes to dynamically manage the monitored data for substation level and central system evaluation. Switching Management Switching Management allows the dispatcher to build, simulate, and verify a complete switching program using a fully graphical user interface and execute the approved switching programs in one step while maintaining compliance with safety and security procedures. Load Management Load Management evaluates and implements energy-reducing strategies such as peak load shifting, load start inhibition, and shedding of non-critical loads to reduce energy cost. The most intelligent load preservation system available, hands down. Speed Speed Power Power Performance Performance Automate & Optimize Your Substation Operations 8 | Real-Time | 9
    Enterprise Solution ETAP Power System Enterprise Solution can maximize the entire production process, reduce losses, and increase profits through continuous monitoring, simulation, and optimization of the system. Operations The ability to seamlessly integrate process information with electrical system constraints is essential to a reliable operation. Virtual testing of operator actions (predicting system response) prior to implementation can reveal potential problems, hence reducing human errors and the risk of service interruptions. ETAP assists operators in making informed and logical decisions to reduce operating costs and improve system reliability. Maintenance Real-time maintenance alerts and assessments of system components insures just-in-time predictive maintenance of critical plant equipment. Mean-time-to-repair and mean-time- to-failure rates are calculated to evaluate the network and equipment online reliability indices. This translates into cost reduction and prevention of expensive unplanned shutdowns. Engineering As the world leader in power system engineering analysis tools, ETAP integrates with data acquisition devices to provide actual system operating condition for the purpose of real-time simulation. ETAP takes the guesswork out of system analysis. Financial ETAP interfaces with existing accounting and billing systems to provide up to the minute energy usage and fuel cost information while providing recommendation and prediction scenarios to minimize peak power consumption and eliminate tariff penalties. Planning System planners can improve performance of production scheduling thus increasing the system capacity using adaptive planning tools provided by ETAP’s trending and prediction functions. As a component of the Enterprise Resource Planning (ERP) system, ETAP optimizes the exchange of information between diverse tiers of an organization while channeling domain sensitive information. 10 | Real-Time | 11
