为保证变电站继电保护装置的运行可靠性,突破原有仅凭经验进行热设计与分析的局限,对国产核心芯片与板卡进行精准建模,采用力导向算法优化热源布局.通过精细化热分析及实验验证表明:本方法改善了板卡局部热点与温度梯度分布,增加了国产化继电保护装置的热安全余量,提升了装置在工程现场长期运行的可靠性.
Thermal Optimization Method of Domestic Relay Protection Device Based on Force-directed Algorithm
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.
