摘要

With the rapid development of deep offshore wind power, flexible direct current (DC) transmission has become the preferred technology option for grid connection. However, large-scale flexible DC systems present complex control and protection hierarchies and multidimensional strategies, Make a huge Challenges to the safe and stable operation and performance testing of control system hardware and software, as well as performance testing. This paper focuses on the KMVA-level offshore wind flexible DC integration project by the China Electric Power Research Institute. A real-time simulation model for electromagnetic transients and a hardware-in-the-loop testing platform were developed using a CPU+FPGA Heterogeneous computing platform with RTLAB and Hypersim. The platform enables system control testing through full-scale hardware control and real-time digital models. Experimental results show the control system's excellent performance, supporting future offshore flexible DC engineering applications.
