Standalone hybrid generation system for the remote area of Thar, Pakistan
Basic Elements
There are two major categories of elements in Simulink:
•
Blocks
•
Lines
Blocks
Blocks are used to generate, modify, combine, output, and display signals. Lines, on the other
hand, are used to transfer signals from one block to another.
There are several general classes of blocks, some of which are:
•
Sources: Used to generate various signals. Sources blocks have outputs but no inputs. One
may want to use a Constant input, a Sine Wave, a Step, a Ramp, a Pulse Generator, or a
Uniform Random number to simulate noise. The Clock may be used to create a time index for
plotting purposes.
•
Sinks: Used to output or display signals. Sinks blocks have inputs but no outputs. Examples
are Scope, Display, To Workspace, Floating Scope, X-Y Graph, etc.
•
Discrete: Discrete Filter, Discrete State-Space, Discrete Transfer Fcn, Discrete Zero-Pole,
Unit Delay, etc.
•
Continuous: Integrator, State-Space, Transfer Fcn, Zero-Pole, etc.
•
Signal routing: Mux, Demux, Switch, etc.
•
Math Operations: Abs, Gain, Product, Slider Gain, Sign, Sum, etc.
Lines
Lines transmit signals in the direction indicated by the arrow. Lines must always transmit signals
from the output terminal of one block to the input terminal of another block. One exception to
this is that a line can tap off of another line. This sends the original signal to two (or more)
destination blocks.
Lines can never inject a signal into another line; lines must be combined through the use of block such
as a summing junction. A signal can be either a scalar signal or a vector signal.
