摘要
针对二十辊可逆冷轧机生产线,介绍了天津电气科学研究院TAC1系列高性能大功率变频产品的应用。整体传动系统采用AIC有源整流单元和逆变器组成公共直流母线形式的多传动系统,首先介绍了系统的装置选型、变压器容量的计算,然后描述了装置并联的高速光纤通信并联方式,以及系统的PROFINET通信网络。通过上位机IBA分析软件记录的装置实时参数曲线,反映了逆变器运行时的转速和转矩精度;使用功率分析仪测量的电网数据对电网侧功率因数进行了分析;同时为了避免装置超温故障导致系统无须停机造成断带,导致废品率提高,系统可对环境温度和装置温度实时预报警,实现了张力可控停机,减少断带几率。该系统在保证系统稳定运行的同时,提高了系统的控制精度,同时减小了能源的消耗。
Application of TAC1 series high performance high power inverter products of Tianjin Electric Research Institute on 20-high reversible mill was introduced.The common DC bus multi drive system consists of active infeed converter and inverter.Firstly,the device selection of the system and the calculation of transformer capacity were introduced,then the parallel connection mode of high-speed optical fiber communication of parallel inverter was described,and PROFINET communication network of the system.The real-time parameter curve recorded by the software was analyzed by the upper computer IBA,and reflected the speed and torque accuracy on inverter during operation;the system used the power data measured by the power analyzer to analyze the power factor of the grid side;in order to avoid the overtemperature fault of the device,the system does not need to shut down and cause belt break,which increases the rejection rate,the system can make real-time warning of the ambient temperature and the device temperature,realizing the tension controllable shutdown and reducing the chance of broken tape.The system not only ensures the stable operation of the system,but also improves the control accuracy of the system and reduces the energy consumption.
