This paper introduced in detail the theoretical basis,control effects,and limitations associated with existing power cor-rection control methods for plateau diesel locomotives in different application scenarios,and proposed an adaptive power control strate-gy,considering the power correction requirements of diesel locomotives operating at high altitudes as the design input.Through a thor-ough examination of operating characteristics of diesels and complex operating conditions at high altitudes,an algorithmic model was es-tablished 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 de-signed,taking into account the fluctuating features in post-intercooling temperature differences between the leading and other locomo-tives 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.
