摘要
为保障模块化串联结构电源系统的正常运行,探讨模块化串联结构电源系统中两级分组控制的故障检测策略.该方法通过优化模块化串联结构电源的故障反馈信号接收机制,引入基于最大功率点跟踪(Maximum Power Point Tracking,MPPT)的两级分组控制直流孤岛检测技术.同时,设计故障判据,并优化检测结果输出流程.通过实际案例验证,文章提出的方法能够在短时间内精准检测出故障,从而显著提升电源系统的运行稳定性.
Abstract
To ensure the normal operation of modular series structure power supply systems,this paper explores the fault detection strategy of two-stage grouping control in modular series structure power supply systems.This method optimizes the fault feedback signal reception mechanism of modular series structure power supplies and introduces a two-stage grouping control direct current islanding detection technology based on Maximum Power Point Tracking(MPPT).At the same time,fault criteria were designed and the detection result output process was optimized.Through practical case verification,the method proposed in this article can accurately detect faults in a short period of time,thereby significantly improving the operational stability of the power system.
