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

長期以來，變電站繼電保護裝置CPU、FPGA等核心芯片完全依賴進口，隨著中美貿易摩擦加劇，尤其是美國《2022芯片與科學法案》的簽署，使自主可控、安全可靠成為智能電網的重要發(fā)展方向［1-2］，繼電保護裝置芯片自主化進程進一步加速。（剩余6047字）
