| Abstract: | Power interface is the important link between the digital simulator and the object to be tested and is crucial to the stability and accuracy of PHIL(Power Hardware In the Loop) simulation. A circuit model of PHIL is built based on the equivalent modelling theory of PHIL interface to analyze its stability. A control strategy of power interface is designed based on the repetitive control theory to ensure the stability and accuracy of simulation. An outer P-control loop of voltage is introduced to improve the dynamic performance. A PHIL simulation platform is established and a 380 V 50 kW power interface device is applied to realize the hybrid real-time simulation of complex system, with excellent stability performance, fast dynamic response and strong robustness. |
