Part 1: The system contains a plant (AEV) and a controller (PLC). The mechanism is divided into two stages: boost and buck stage. Stage 1: A DC source of 220 V is connected to the plant as an input and it needs to be boosted to 400 V. Furthermore, two input current signals need to be tracked to the reference signals, respectively. The reference signal could be any sinusoidal or disturbed random signals of 14 A and both current signals are in parallel with a sum of 28 A. The output voltage needs to be regulated at 400 V constantly. Stage 2: The boost stage outputs are taken as inputs to the buck stage. Output voltage needs to be regulated (from 400 to 220 V) at 220 V during this stage and the input current signals must be tracked to the desired signals (desired or reference signals could be any disturbed signals of around 34.5 A each and must be in parallel, with a sum of 69 A). The tasks to be performed are mentioned in the following lines:- 1. Illustrate how an AEV works and label all its important parts. Also critically analyze the future of Electric Vehicles both globally and locally. 10 lines (max.). 2. Graph suitable PFDs and diagrams for each stage of the AEV. 3. Figure out the ladder logic for each stage and simulate it in software. 4. Analyze the system and control on PLC and plot suitable results for output voltage and input currents (both separate and combined) against time (optional but more than 10 seconds at least) along with the respective desired signal using an oscilloscope. Part 2: Now let use suppose that the system contains three sources: source 1, source 2, source 3. The system draws input currents from each source and voltage of source 1 is same as part 1. Source voltage is 250 V and the input currents are of 10 A each (in parallel). Source 3 voltage is 180 V and input currents are 5 A each (in parallel). In the next stage, source 1 and 2 need to be charged and the system takes 400 V input voltage and input currents for source 2 need to be tracked to the desired currents of 6.25 A rms (sinusoidal/disturbed) each. For source 3, the current to be tracked to desired value is 2.5 A rms (sinusoidal/disturbed). The source 2 and 3 output voltages must be maintained (regulated) at 250 V and 180 V, respectively. Conditions and Logic: The system operates in different modes during both stages: boost and buck stage. The working cycle must be of 30 sec for this part. System operates for first 10 sec on the source 1 while other sources are kept off during this period. Moreover, from 10-20 sec time period, the system operates on source 1 and 2 only and 3rd source is kept off. Additionally, for the time period of 20-25 sec, system operates on source 1 and source 3 only and source 2 is kept off. Lastly, from 25-30 sec period, the system operates on all three sources. Tasks: The tasks to be performed are mentioned in the following lines:- 1. Illustrate the ladder logic for all the modes and repeat it for the next stage (buck stage) as well. 2. Graph suitable PFDs and other relevant diagrams. 3. Test the logic on PLC and document the findings. 4. Plot suitable results using oscilloscope.
