Investigation on Variable-speed Coupling Twin-engined Driving System Synchronizing Regulation and Power Balance Control

介绍了工业生产实际当中常见的2种调速型液力偶合器多机同步运行控制方式,分别针对风机并联偶合器同步调速控制及带式输送机双机驱动运行功率平衡问题提出相应的控制方案。针对2类系统的关键控制参数(涡轮输出转速和电机工作电流)进行了PID闭环控制跟踪响应实验,得到了偶合器调速过程动态响应结果。

Two types of variable - speed coupling multi - engined drives running control manners widely used in practice are discussed. Different schemes are suggested for the synchronizing regulation and power balance nvolved coupling fan speed system. Closed - loop PID control, response test with critical parameters （output soeed of the turbine and working current of motor） is done. Speed regulated dynamic response results for the coupling speed regulating system are achieved.
