摘要
针对煤矿用大功率整流电源存在的功能单一、缺乏保护措施的问题,设计基于SIMADYN数字处理器的煤矿用大功率整流电源系统。重点分析了主回路系统、控制系统以及保护系统设计,并完成电阻负载试验和充电机应用试验。电阻负载试验结果表明,该大功率整流电源系统满足设计要求,可实时、高效的调节每台机组的直流电流值,误差可控制在0.5%左右;充电机应用试验结果表明,该大功率整流电源系统可将输出充电电流提升至DC300A,可将充电时间减少约16%。
Aiming at the problems of single function and lack of protection measures of high power rectifying power supply for coal mine,the author designs a new high power rectifying power supply system for coal mine based on SIMADYN digital processor,mainly analyzes the design of main circuit system,control system and protection system,and completes resistance load test and charger application test,whose results show that the high power rectifying power supply system meets the design requirements,can efficiently adjust the DC current value of each unit in real time,control the error at about 0.5%,increase the output charging current to DC300A,and reduce the charging time by about 16%.
