Electrical Equipment Testing With Power Hardware-in-the-Loop

Use power hardware-in-the-loop testing to validate connected and fully-powered electrical equipment thoroughly

Electrical engineers use power hardware-in-the-loop (Power HIL) testing to test electrical equipment that is connected and fully powered. Connect the electrical terminals of your hardware to a virtual electrical system such as a transmission or distribution network, microgrid, electric car, more electric aircraft, or fully electric ship. Power HIL testing enables the thorough validation and verification of your electrical equipment’s typical operation and fault conditions before final deployment to the power grid, electric vehicle, or any other DC or AC power system. Typical equipment under test (EUT) includes power converters, protection relays, EV chargers, or onboard power system components. High-bandwidth electrical interfaces are emulated using power amplifiers ranging from a few hundred watts to megawatts.

“Speedgoat together with MathWorks products offer a very efficient workflow to design, test and validate algorithms for Battery Management Systems.”

Featured Application Use Cases

Testing of Electrical Equipment

When developing electrical equipment, testing the integration with the rest of the system is rarely possible due to limited availability, high cost, or safety considerations. For example, it usually is impossible to connect to the power grid when testing renewable energy integration. When testing electric powertrain components, the electric motor or battery pack may not be ready. One cannot reproduce extreme and fault conditions with field testing. Therefore, engineers use Power HIL testing to thoroughly test power equipment under typical and fault conditions by connecting to a virtual electrical plant.

Power HIL is a technique in which electrical equipment is incorporated into an electrical simulation through its electrical power interface. A power amplifier creates the electric power interface with the equipment. The actual and simulated interfaces are synchronized via a high-end real-time simulation.

Grid and Battery Emulation

new

Test renewable energy sources, power converters, or protection relays against virtual AC grids, DC grids, or battery packs using Power HIL with Speedgoat real-time solutions. Test typical operating conditions and electric fault conditions thoroughly by using power amplifiers, virtual transmission lines.

Simulate the grid network or battery pack dynamics in detail using Simulink and Simscape Electrical. There are several examples to get started, including microgrids, grid-tied inverters, renewable energy sources, and energy storage solutions.

Electric Motor Emulation

Use electric motor emulation to test power inverters and EV power converters against a virtual motor. Emulate any motor type like internal permanent magnet synchronous machines (IPMSM), induction motors, or switched reluctance machines (SRM). You can even include non-linear effects, saturation, and space harmonics by using specific motor data from FEA tools. Use our joint solution with EGSTON Power to emulate motors from 10 kW up to 2 MW.
