摘要

文章以高海拔地区内燃机车功率修正需求为设计输入，详细介绍了目前高原内燃机车在不同运用场景下的功率修正控制方法的理论依据、控制效果和局限性，提出了一种自适应功率修正控制策略。通过对柴油机工作特性和高海拔地区复杂运行条件的深入分析，建立了其功率输出与海拔、环境温度、增压器排温、增压器转速等参数之间的算法模型，并结合多机重联隧道运行工况下主从机车中冷后空气温差变化特性，设计了一种全场景自适应的柴油机功率修正控制算法，并通过现场试验验证其正确性，实现了在保证柴油机可靠性的基础上最大程度发挥柴油机功率输出。

Abstract

This paper introduced in detail the theoretical basis

control effects

and limitations associated with existing power correction control methods for plateau diesel locomotives in different application scenarios

and proposed an adaptive power control strategy

considering the power correction requirements of diesel locomotives operating at high altitudes as the design input. Through a thorough examination of operating characteristics of diesels and complex operating conditions at high altitudes

an algorithmic model was established to capture the relationships between diesel power outputs and parameters such as altitude

ambient temperatures

supercharger exhaust temperatures

and supercharger speeds. Subsequently

a full-scenario adaptive diesel power correction control algorithm was designed

taking into account the fluctuating features in post-intercooling temperature differences between the leading and other locomotives while operating under coupled conditions in tunnels. Furthermore

the validity of the proposed algorithm was verified through field experiments

where the power outputs of the diesels were maximized while ensuring their operational reliability.
