摘　　要：针对小浪底电站地下厂房桥机原电气系统技术较落后、控制精度较差、电气系统设备老化严重及设备故障率高等问题,采用目前较成熟先进的基于数据总线式PLC控制技术和全数字式矢量变频控制技术,全面升级改造了原电气控制系统和电气传动系统(包括电动机),改造后的电气系统显著提高了桥机的控制精度,也提高了设备运行可靠性尤其是并车运行时的同步可靠性。Electrical system of crane for underground powerhouse of Xiaolangdi hydropower plant has some problems, such as backward in technique, poor precision of control, aging equipment and high failure rate. The advanced PLC control technique based data bus and digital vector variable frequency control are used to update the original electrical control and driving system （including motor）. Improving electrical system increases the control precision of crane and raises the operation reliability of equipment, especially the synchronicity when 2 cranes working together.
