This paper proposes a component-oriented modeling method to enhance the computational efficiency of FPGA-based real-time digital simulators (FRTDS) in power system simulation. It presents a user-friendly and scalable modeling process for different types of elements in FRTDS. By applying the concepts of combination and reconstruction of components, it becomes better suited for combined elements with fixed connection modes and elements that require online model replacement. The variable declaration structure and node elimination strategy in the simulation script are optimized to fit better with the hardware structure of FRTDS. A substation is simulated in FRTDS to verify the correctness of the component-oriented modeling method and its ability to improve computational power.
This paper proposes a component-oriented modeling method for power system simulation, which optimizes the modeling process of the FPGA-based real-time digital simulator (FRTDS) to enhance its computational efficiency. In this paper, a component modeling method for various types of elements in the power system is presented, which makes the modeling process in FRTDS more user-friendly and highly scalable. By applying the concepts of combination and reconstruction of components to electrical components, the component-oriented modeling method becomes better suited for combined elements with fixed connection modes and elements that require online model replacement in the power system. Utilizing the characteristics of component-oriented modeling, the variable declaration structure and node elimination strategy in the simulation script are optimized, enabling the simulation script to fit better with the hardware structure of FRTDS. Additionally, a substation is simulated in FRTDS with a simulation step size of 50 mu s, thus verifying the correctness of the component-oriented modeling method and its ability to improve the computational power of FRTDS.
