AMETEK Programmable Power, the global leader in programmable AC and DC power test solutions has released the External Drive (-EXTD) option for the RS Series of high-power regenerative programmable AC sources.
Hardware-in-the-loop (HIL) is a technique that is commonly used in real-time embedded systems for electrical emulation of a power plant. Using HIL techniques allows simulation of real-time feedback and control of such complex systems. Most common applications include simulation of power plants, hybrid electric vehicles and most recently, renewable energy generation and their effect on the utility grid.
The RS Series features advanced Digital Signal Control technology to the power amplifiers within the source. The source features typical remote control methods, such as GPIB or LAN that inherently introduces control delays in the 100’s if milliseconds which do not simulate realtime control. The introduction of EXTD allows real-time control via analog signal so delays are typically reduced to 100 microseconds (figure 1). EXTD essentially allows the RS to be used as a high bandwidth amplifier, while the internal DSP continues to monitor the output in order to ensure safe operation. RS Series_1Available with outputs ranging from 90 kVA to 1MVA, the RS is the latest series of products to use AMETEK’s high-performance, pulse-width modulation (PWM) switching technology to provide advanced performance solutions for AC power test applications.
