Energy Management system of hydrogen train

 

  24 TH February 24, 2023   Actions for Week 4:        We assigned finishing work into different group members. As the the academic work parts are nearing the end. We  divide the group into three parts: Yanwu Zhu to complete the EMS code; Zengzhi Jie and Yankai Xu to do poster; Zijie Zhang and Li Yi to write blog. Successfully, we accomplished the tasks including completing the blog and poster design. In addition, the graph displaying the energy consumption difference before and after the using of EMS was made finally.   the code is improved and generally completed, basically meeting the expected goals. It can not only manage the energy from fuel cell, but also calculate the total consumption of hydrogen based on EMS and make a comparison with original situation. Also, all comments are exchanged into English. Below are some demonstrations of codes and figures Last but not least, we finished preparation work for presentation and some ot...

  17 TH February 2023  Aim for Week 3: 1.  Improved original hydrogen consumption calculation. 2. Build EMS rule for specific hydrogen train.  3. Develop EMS code. Actions for Week 3:  For a more rigorous calculation,  according to the chemical equation:         for the calorific value of hydrogen combustion, the heat required for the complete combustion of 1 kg of hydrogen is obtained. Secondly, According to the reading reference,  we can get: η 1 fuel cell combustion efficiency is about 49.5%,   η 2 DC conversion when the efficiency is about 91%, remove the train air conditioning, lights and other equipment power supply for the train on wheels energy conversion efficiency is about η 3 = 77%. In the end, we just need to select the train and get the total energy requirement by simulation to calculate the hydrogen consumption by    With the help of the reference online and the flow chart for calcu...

  10 TH February 2023   Aims from Week 2: 1.Clear calculation method and formulas.  Preliminary design codes.      2.Keep reading relevant materials. Actions for Week 2:   In week 2, two groups steadily made progress to their own tasks based on the first week’s division.  EMS is a challenged  target, the small group still need one week to finish their related learning. To calculate the total consumption of hydrogen, we basically achieved the building process based on the brief structure given by our academic advisor. What’s more, we succeeded in obtaining the efficiency of the hydrogen fuel cell as well as the battery by studying the reference online. In addition, we made attempt to understand the different situations of speed and battery charge and discharge states when it comes to managing energy.                                   The figure abov...
