Project 1

The logic which is been told to develop in this that if the powerdemand from the vehicle is less than the minimum FC power than the FC must go on standby and the power should be supplied from the battery storage system and if the power demand is greater than the min FC power than the FC should be used and if the power demand of vehicle is for than the max power of FC than the battery should supply the power.

The simulink model is been developed for this as shown below.

For this ,min FC power is kept between 0 to 1000w

Operating region of FC is 1000w to 9000w

max power demand is set till 9000w to 10000w

Simulink Model.

 

The signal buider block is used as the input to give the power demand required by the vehicle ,the simultion is been run for 598sec and the output such as FC power,battery power and FC status are been studied by the connecting to the scope.

Inside the subsystem is shown ,the interval test block used for setting the limits of the FC maximum and operating region,the limits are been set as discussed above.Then as per logic the switch block are been set and the output is been connected to FC or battery as mentioned in flowchart.

 Signal buider as shown above.

 From 0 to 210sec the power demand is between 0 t0 1000w and from 210-390sec the power demand is between 1000-9000w and for rest of the time its above 9000w so respectively first the battery should provide the power at the same time the FC should be at standby and when the power demand is greater than min FC power than FC should be used and if the power demand exceeds max FC power than the battery should be switched back.

Results can be seen below

 From the results its clear that the logic which is been developed is full proof and working properly as per the logic defined.
