Optimum allocation method of electric quantity and power for toilet insulation equipment of electric locomotive

Abstract

The invention belongs to the technical field of power supply for heat preservation equipment of electric locomotives, and relates to a method for optimal configuration of electric quantity and power of heat preservation equipment for toilets of electric locomotives. The specific steps are: by extracting the relevant parameters of the thermal insulation equipment; establishing a thermal network model; obtaining the minimum value of the heat dissipation power and the total energy consumed by the heater as the goal, optimizing and determining the controllable parameters of the thermal insulation equipment, and then determining the power consumption of the electric locomotive toilet thermal insulation equipment. The power is optimally configured to improve the capacity utilization of the battery, effectively reduce the capacity of the battery, and correspondingly reduce the volume, weight and cost of the battery. In addition to reusing the heater of the original electric locomotive bathroom heater, the other devices of the heat preservation equipment are independent from the original system, which has strong versatility and is easy to promote.

Description

technical field [0001] The invention belongs to the technical field of power supply for heat preservation equipment of electric locomotives, and relates to a method for optimal configuration of electric quantity and power of heat preservation equipment for toilets of electric locomotives. Background technique [0002] For Harmony electric locomotives, the toilets for drivers and passengers are mainly used to: collect and temporarily store human excrement, and there are also sinks, mirrors and foot stoves inside to provide a humanized toilet environment for drivers and passengers. Such as figure 1 , 2 As shown, the toilet is composed of the upper part of the car and the lower part of the car. The bathroom on the car is a cabinet close to sealing, and facilities such as toilet, water tank, distribution box (ie control cabinet), dirt box and pipeline are housed in the cabinet. The under-vehicle pipeline provides the connection and discharge of water and air for the bathroom ...

AI Technical Summary

Problems solved by technology

[0007] The disadvantages of the above prior art are: the impact of ambient temperature and heater power on the battery capacity is not considered, and the battery capacity is not optimized

In addition, because of the thermostat inside the shared bathroom, the maintained temperature value cannot be changed, and the power consumption cannot be optimized through temperature adjustment
