User defined procedures enable the execution of frequently used sets of macro commands, for example calculations or reporting actions.

 

Definition of a procedure:

Procedure ( procedure_name )

...

...

End

 

Using a procedure:

Call ( procedure_name )

 

The procedures do not have parameters and use only global variables. The definitions may not be nested. However, a previously defined procedure may be called in a next procedure definition. It is allowed to recursively call procedures.

 

Example:

procedure(calculate_deviation)

// calculate (U-Uref) / Uref * 100%

set(x,U)

subtract(x,Uref)

divide(x,Uref)

multiply(x,100)

end

 

procedure(print_voltages)

text(U:6:2,' kV   ',Uref:6:2,' kV   ',x:6:2,' %')

end

 

loadflow(0,,true)

if(Network.Result,=,'LF')

   text('Voltage     Reference   Deviation')

   text('=======     =========   =========')

   set(Uref,node('MS-Station').U)

   forselection(node('MS-net'),MyNode)

      set(U,MyNode.U)

      call(calculate_deviation)

      call(print_voltages)

   end

else

   text('no loadflow')

end 

 

On the demo network this macro results in:

Voltage     Reference   Deviation

=======     =========   =========

 10,36 kV    10,36 kV     0,00 %

 10,08 kV    10,36 kV    -2,75 %

 10,31 kV    10,36 kV    -0,48 %

  9,93 kV    10,36 kV    -4,16 %

 10,37 kV    10,36 kV     0,09 %

  9,93 kV    10,36 kV    -4,16 %
