It transforms LVDAC-EMS software and the workstation’s computer into a local workstation that can be monitored and controlled over a local network from a supervisory computer. Using the OPC Server protocols, SCADA-EMS enables users to design their own interfaces by calling the different applications running on the local workstations. SCADA-EMS enhances LVDAC-EMS by adding several new features: – Collect data from local workstations. – Observe and control one or multiple stations from one or multiple supervisory stations. – Remotely control several applications in a lab. – Use a workstation in a different room to present actual demonstrations over the network in your classroom without having to bring a workstation to class. – Introduce students to the fundamentals of SCADA in a grid context. – Recreate a complete grid with several different applications running. The LVDAC-EMS software is a userfriendly tool that facilitates the use of the various functions which can be implemented with USB peripherals, such as the Data Acquisition and Control Interface (DACI) and the Four-Quadrant Dynamometer/Power Supply. Together, the DACI and LVDAC EMS provide a complete set of modern computer-based instruments to measure, observe, analyze, and control electrical and mechanical parameters. The provided instruments eplace a multitude of actual data acquisition devices and include voltmeters, ammeters, power meters, frequency meters, efficiency meters, impedance meters, power factor meters, energy meters, torque and speed meters, an oscilloscope, a phasor analyzer, a harmonic analyzer, and a spectrum analyzer. – The Metering window displays up to eighteen meters that can be configured to measure a multitude of parameters. – The Oscilloscope displays up to eight waveforms simultaneously. Each waveform is of a different color for easy identification. – The Phasor Analyzer displays the phasors related to measured voltages and currents instead of the values and waveforms related to these voltages and currents. – The Harmonic Analyzer allows observation and analysis of the harmonic components in the measured voltages and currents. Training Packages in Electric Power Technology Software Programs The DACI and LVDAC-EMS also allow manual and timed data recording. The recorded data can be saved to files in any specified location, graphically represented with the provided graph plotting tool, and exported into a spreadsheet application. The DACI and LVDAC-EMS can also be used with the Four-Quadrant Dynamometer/Power Supply to implement a variety of control functions for advanced training in various fields of electricity and new energy, including electric power technology, AC/DC rotating machines, renewable energy, transmission lines, and power electronics. The LVDAC-EMS software and the Data Acquisition and Control Interface allow complex power system applications such as hydropower generators, large-scale wind turbines (PMSG and DFIG), high-voltage direct current (HVDC) transmission systems, static var compensators (SVCs), and static synchronous compensators (STATCOMs) to be implemented. SCADA windows are available in the LVDAC-EMS software for these complex applications to ease system control and monitoring, as well as to allow students to quickly understand what is going on in these applications. Free download on our → website. A locked version of the SCADA-EMS software program can be downloaded from our website and can be unlocked by a USB dongle. A dongle unlocks five workstations; order as many dongles as required. LVDACEMS is required to run SCADA-EMS. Order no. 8094377
