Research on High Performance Electromagnetic Transient Simulation Platform of HVDC Transmission System

High performance electromagnetic transient simulations play an indispensable role in the field of modern electronic design and research and development, providing engineers with the ability to predict and optimize product performance during the design phase, significantly reducing the number of iterations required in the actual manufacturing and testing process, and effectively reducing the cost and time of research and development. These software not only have a critical impact on improving the efficiency and performance of product design but also play a crucial role in promoting technological innovation and achieving autonomous control of the industry. Restricted by modelling and simulation capabilities, computational efficiency, scalability and other aspects, traditional electromagnetic transient simulation tools are difficult to adapt to the needs of new power systems. In this paper, we design a power modelling and simulation software for a new type of power system. The software supports a variety of numerical integration methods, adapts to the characteristics of new power systems, effectively eliminates the problem of numerical oscillation, and can construct multiple control system models with the same structure but different parameters. This paper takes the Tianzhong DC project as an example, builds a simulation model in the SimuNPS environment, and verifies the rationality and superiority of the simulation platform by comparing it with the traditional electromagnetic transient simulation software.
