Abstract：To ensure the operation reliability of relay protection devices in substations， by breaking through the limitations of the original thermal design and analysis merely based on experience， builds precise models of domestic core chips and printed circuit boards， and optimizes the layout of heat sources by using force-directed algorithm. The refined thermal analysis and experimental verification indicate that the optimized method improves the local hot spot and temperature gradient distribution of the pcb， increases the thermal safety margin of the domestic relay protection device， and reinforces the long-term operation reliability of the device on project site.

Keywords：domestic chip; relay protection device; precise modeling; force-directed algorithm; refined thermal analysis; reliability

0引言

长期以来，变电站继电保护装置CPU、FPGA等核心芯片完全依赖进口，随着中美贸易摩擦加剧，尤其是美国《2022芯片与科学法案》的签署，使自主可控、安全可靠成为智能电网的重要发展方向［1-2］，继电保护装置芯片自主化进程进一步加速。（剩余6047字）
