Dear friends, I have been implement a test power system in the simulink by simpowersystems blocks without any problem. I need use "3-phase PLL block" in the simpowersystems>>Extra library>>control block, but simulation hits this error:"Unable to reduce the step size without violating a minimum step size of 7.4732139418071823E-017 at time 0.02103522720223934 for model". I used powergui with discrete simulation type and sample time is equal 5e-6 ;that is very long with 2 sec. for my necessity time simulation. please help me to solve this error.
Yours faithfully.
