摘　　要：加强再生制动能量利用技术研究及应用,有助于铁路节能、节支和绿色发展。为实现再生制动能量直接与高效利用,基于变电所间再生制动能量调度互用原理,设计了一种由能量管理装置和能量调度装置构成的电气化铁路再生制动能量利用系统,提出了基于牵引负荷需求、再生制动能量、系统额定功率和预设调度阈值等多约束条件的最优控制策略,并通过示范工程进行了全面的现场应用验证。测试结果表明,系统方案设计合理,控制策略正确可行,再生制动能量利用率达到62.5%,符合设计预期。It will contribute to the energy saving and green development of railways by means of strengthening the research and application of regenerative braking energy utilization technology.In order to realize the direct and efficient use of regenerative braking energy,based on the principle of mutual scheduling use of regenerative braking energy between substations,a kind of regenerative braking energy utilization system for electrified railway that composed of an energy management device and an energy scheduling device was designed.Taking into account multiple constraints,including the traction load demand,regenerative braking energy,system rated power,preset scheduling threshold and so on,an optimal control strategy was proposed.Finally,comprehensive on-site tests were carried out through demonstration project.The test results show that the system design is reasonable,the control strategy is correct and feasible,and the regenerative braking energy utilization rate reaches 62.5%,which meets design expectations.
