bode plots in power systems smulink

In power system from simulink, is there a block to capable of tracing bode diagrams? If not, does anyone knows an easy method to get bode diagrams from the circuit elements at power system (not from Matlab or Simulink transfer functions) ?

Many thanks for the help, Cheers, Rudi

If I understand correctly, you need to get the frequency response of the circuit. you can use the LTI Viever of Powergui. read HELP about powergui

Use Simulink Control Design to linearize your model. If it does not linearize analytically, use frequency response estimation.

Example showing how to do exact linearization : http://www.mathworks.com/products/demos/slcontrol/beaver_control/index.html

just type the watertank in your comond window. There is one example by this name. in side simulink control design, linear analysis plot is there. just go inside and find bode plot block. use this bode block and linerize this with your circuit as it did in watertank example.
