| 摘 要： | 针对港口起重机械位能性负载特性,通过分析起升电机的控制原理及状态方程,建立了基于PLC和变频器的起升电机拖动测试系统。通过转差频率控制的控制策略,进行了模型的仿真与试验分析,从而验证了变频调速控制系统具有较大的节能空间,尤其对于满载及重载的控制更为明显。这为港口起重机械的节能提供了理论和试验基础。

| Abstract: | According to load characteristics of the port crane, through the analysis of lifting control principle and the state equation of the motor, the motor drag test system had been established base on PLC and inverter, the simulation and experimental analysis of the model were carried out by the control strategy of the transfer frequency control. It was verified that the VVVF control system had large energy saving space, especially for full load and heavy load control, which provides a theoretical and experimental basis for the energy saving of port cranes. |
