Study on the relationship between dynamic energy utilization of power plant in extremely cold environment

By constructing a complete power plant model and using the idea of coupling simulation, this paper analyzes the energy utilization characteristics of vehicles under the influence of different environmental factors. It is found that with the decrease of environmental temperature, the overall energy consumption of vehicles is reduced by about 10.8%, the driving energy ratio is increased by about 1.9%, the exhaust energy ratio is reduced by about 3.0%, and the heat dissipation energy ratio is increased by about 5.1%. The energy consumption of the fan is reduced by about 6.2%. Based on the change in the proportion of vehicle energy, the cause analysis is carried out, and previous studies are made for heavy vehicles to adapt to different environments.
