Calculation of Coach Body Heat Transfer Coefficient for the High-Speed Railway Train in China It can keep a comfort passenger environment and decrease demand for the cooling load of air-conditioning system. The determination of coach body heat ... S Shi,HX Gao,M Li,... - 《Advanced Material...
There are a lot of important applications of PPP(Purchasing Power Parity) in practice.One usually uses the linear weighted method to calculate PPP in practice.In this paper the equations used to calculate PPP are deduced by the maximum utility law.The major conclusion of this paper is that it...
Here we present a method to combine half-hourly publicly available electrical\ngeneration and interconnector data to create a timeseries that approximates\nGreat Britains electrical demand. Publishing the method and the data provides a\nresource to the wider community that can be further enhanced or...
The data of the distribution feeders, transformers rating and percentage loading are presented in Appendices 1 and 2, respectively. The total power demand supplied through the two feeders is about 3.5 MVA. Lf and Lsf are assumed to be 0.8 and 0.688, respectively. Electrical transient Simulation ...
Battery EDVs can charge during low demand times and discharge when power is needed. Fuel cell EDVs generate power from liquid or gaseous fuel. Plug-in hybrid EDVs can function in either mode. Each vehicle must have three required elements: (1) a connection to the grid for electrical ...
The heat accumulator operates in discharge mode during the hours of maximum electricity demand. During this time, regenerative extraction № 1 from the high-pressure cylinder (HPC) to the high-pressure heater № 1 is turned off. The electric power of the turbine unit is increased by increasing...
Therefore, the maximum contact force of the HD occurs at the position with the smallest no-load backlash. It can be seen that at the maximum contact load, the disposable HD is lower than that of the conventional HD. In addition, there are certain differences between the meshing areas of ...
