摘要：

Real-time simulation technique of power systems is becoming realizable due to the growing significant computational power of computing platform. This paper builds a real-time prototypical platform based on PXI and LabVIEW as its main hardware and software architecture. Taking advantage of the integration characteristics of NI products, the platform embodies high expansibility and good compatibility and fits the needs of studying in university labs. Based on the platform, a real-time algorithm considering the multiple switching events is developed with a tradeoff between the computing power and the simulation accuracy. To validate the algorithm on the real-time prototypical platform, three-phase voltage source converter circuit and buck chopper circuit are studied with a 10 mu s time-step and 2kHz PWM frequency. The captured real-time results demonstrate high goodness of fit in comparison with the offline simulation of the systems in PSCAD/EMTDC.
