Thread Subject:

need help for Compliation error

Hi everyone,
           Anyone know how to solve this error?
Derivative input 1 of 'untitled/Active and Reactive Power control/Integrator2' at time 0 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances).

Thanks

Jade,

Did you try the following tech note:
Why am I receiving error messages about singularities in my Simulink model?
http://www.mathworks.com/support/solutions/en/data/1-16GR6/?solution=1-16GR6

Another one with the same error message
Why do I receive division by zero errors when passing in transfer functions with leading zeros for denominator in model reference arguments?
