Then, considering the demand of the prototype platform of real-time simulation, the PXI computing platform is established.The hardware architecture based on peripheral module and external hardware, and the software architecture of programming tools such as Lab VIEW and its accessories, are used to build a real-time simulation prototype platform for power system design, analysis and research.Through two typical circuit examples with multiple switches, the algorithm validity and applicability of the prototype platform based on the real-time simulation are verified.
