How to solve the following error whiling running the system with the Wind generator with induction motor along with the PV and grid system

Derivative of state '1' in block 'untitled/Wind Turbine Induction Generator (Phasor Type)/Data acquisition/Mean Value/integrator' at time 0.00085000000000000006 is not finite. The simulation will be stopped. 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).

Please help out, where to change the parameter to get off from the error
