1 On Board Power Electronics Real-time Simulation, Verification and Validation Martin Belanger American Sale Manager 1

2 OPAL-RT TECHNOLOGIES Established in 1997, HQ in Montreal, CA Offices, subsidiaries and distributors worldwide Over 160 Employees More than 600 customers More than 20% of turnover reinvested in R&D Fully digital simulators for MIL, RCP, HIL, PHIL Leader in Power Electronics, Electrical Drives and Power Systems applications Integrated with MATLAB/SIMULINK COTS HW and SW based Compatible with Software Industry standards 2

3 Why Power Electronics Real-time Simulation, Verification and Validation Early design validation Simulation + Prototyping Testing on the real system is not always practical Reduce the risk of damaging equipment while testing Software regression testing Faster time to market & improved reliability Sorry, the controller was not tested to handle IGBT failure! 3

4 On Board Power System Overview 4

5 Application Example HIL Testing and RCP Testing Testing the controller against a virtual system Simulator Analog Outputs Digital Inputs Measurements Firing Pulses Controller Measurements Controller Firing Pulses Analog Inputs Digital Outputs Measurements Firing Pulses Simulator Control Logic 5

6 HIL Application Example Designing & testing a power electronics controller Measurements Firing Pulses Controller 6

7 Fixed-Step Computing for Real-Time A Typical Simulation Step Model outputs Inputs / Outputs Model Computation Waiting for next step 0 us 50 us Step size I/O time Execution must be deterministic Simulation must be as real as possible Simulation time must follow the real time Controllers expects a precise I/O update 7

8 Challenges of Electric Marine World and More Electrical Aircraft Integration of new converter topologies into the ship / MEA on-board system Complex control laws for the optimal control of electrical systems (converters, electrical machines, ) New measuring and protection devices: sophisticated and communicating Helping academic and industrial researchers to develop innovative electrical systems 8

9 Tests and Validation Real-time simulation best way to test and validate these converters Instead of a physical prototype a virtual replica of an airplane or ship s on-board power supply equipped with power converters Simulation makes possible the emulation of detailed converter operations to test and validate different control systems Aviation 9
