Addressing the Challenges of Onboard Power Systems Testing

Over the last decade, onboard power systems have advanced significantly due to the increased adoption of More Electrical Aircraft (MEA), All Electric Ships (AES) and electric high-speed rail within industry. By replacing certain mechanical, hydraulic and pneumatic functions with electric systems, engineers can now reduce costs, increase architectural flexibility and improve acoustics. While onboard power systems offer significant benefits, stringent regulations concerning reliability and survivability require more comprehensive control and protection testing. As a result, airplane, ship and train manufacturers and suppliers must spend more time designing, testing, validating and certifying this new generation of complex electrical systems.

Moreover, the implementation of newer electrical technologies within onboard power system designs promises to pose still greater challenges requiring, more efficient tools and processes for this emerging area.

More Electrical Aircraft (MEA) Pushes HIL to New Heights

The increased usage of electrical power intensifies the power demands on the electrical system, placing new constraints on dynamic performances and power quality. Today’s new power systems architectures must be designed, extensively analyzed, tested, validated and certified prior to implementation in actual aircraft.

Real-time simulation of MEA has been used ensure compliance with a wide variety of avionics test standards. Read more about using real-time simulation on the Bombardier Global Express for Avionics standard validation.

The Next Generation of Testing Tools

OPAL-RT provides the widest range of proven, state-of-the-art real-time simulation solutions for engineers working on onboard power systems applications. Accelerate projects by testing designs with Hardware-in-the-Loop (HIL), while reducing overall project cost and staff and equipment risks. Benefit from the same advanced OPAL-RT solvers and libraries already being used across the industry to precisely simulate complex onboard power systems.
Onboard Power Systems HIL Testing tools - ARTEMiS-SSN

ARTEMiS-SSN

ARTEMiS-SSN provides the industry’s fastest and most accurate solvers for microgrid and onboard power system applications. With ever-shorter configuration of transmission lines and thinly coupled grids, standard HIL solving methods can be prevented from work optimally.


ARTEMiS solvers and algorithms use advanced decoupling techniques to circumvent this limitation, while providing accurate real-time simulation results.
