凿井绞车群变频调速集控系统设计

Design of variable frequency adjustable speed centralized control system for sinking hoists

针对传统凿井绞车控制难以实现快速准确就位、缺乏现场数据记录的缺点,设计了基于模型参考PID自适应差速补偿的同步控制算法,利用增量式轴编码器、SIMENS S7-200控制器以及安川G7变频器,实现了对4台凿井绞车的同步平衡控制,加快了立井施工的进度,同时监测和记录了凿井绞车的实时运行参数,为凿井绞车性能的评判提供了依据,具有良好的经济效益。

In view of difficulties in rapid and accurate location and lack in field data recording during the control of traditional sinking hoists,the paper designs a synchronous control algorithm based on model references PID self-adaptive differential compensation,which makes use of incremental shaft encoder,SIMENS S7-200 controller and YASKAWA transducer G7 to realize the synchronous balanced control of four sinking hoists.Thus,the speed of shaft construction raises,and the real-time operation data of the sinking hoists are monitored and recorded,which offers basis for assessing the performance of sinking hoists and achieves excellent economic benefits.
