摘　　要：为解决当前大功率电力机车无法实现全速度范围之内对其稳定、安全控制的问题,在对大功率电力机车牵引系统简单概述的基础上,以HXD2C型电力机车为研究对象,为其匹配性设计了全速度范围之内的分段矢量控制策略;针对无电状态和传统准转矩控制劳动量大的问题,设计了直流电压控制策略和准恒速度控制策略。经试验表明,调制控制策略可实现对电力机车的稳定安全控制,且总效率可达86%。In order to solve the current problem that high-power electric locomotives cannot achieve stable and safe control within the full speed range,based on a brief overview of the traction system of high-power electric locomotives,a segmented vector control strategy within the full speed range is designed for the HXD2C type as an example,and a DC voltage control strategy and a quasi-constant speed control strategy are designed for the problem of no power state and the large amount of traditional quasi-torque control labor.The modulated control strategy can achieve stable and safe control of the electric locomotive and the total efficiency can reach 86%.
