I want to study the stability of a single machine infinite bus system with MATLAB. My problem is not in simpower systems, but in simulink.
Hello Abdollah .... If I understood you correctly, you modeled your power system (i.e., generator ) using Simulink functions and signal connections and you want to implement a 3 phase fault at the generator terminals ...well, you can model the three phase fault mathematically to go along with the mathematical-based model you have built. However, a better solution will be to use the SimPower 3 phase fault block, by using connection ports at the terminals of the generator, hence you can combine between the classical simulink function-based signal line subsystems with Simpower blocks ....... Search "Connection Port" ........ Hope that answers your question ..... Good Luck.
hello Dear Mohammed,
I was modeled my system with matlab function block,and solving differential equations using ode methods,i was modeled 3-phase fault by setting the Vt to zero for a period of 100 ms of time, is this way true?
اگر خودت معادلات دیفرانسیل مدل کردی تا حلشون کنی باید سیستم در نقطه کار مناسبی در نظر گرفته شده باشده و مدل ژنراتور بر اساس ولتاژ پایانه باشه تا بتونی در بازه های زمانی بروز خطا ولتاژ ترمینال را صفر بدی
