Öz Understanding and researching about power quality techniques are one of the most important issue in power plant sectors, costumers and has been explored by many researchers. And it becomes more important to understand the causes of electronic equipment being damaged and effected by power disturbances, for this purpose there is need for reliable techniques and algorithms that can work for power quality analysis. In this paper, the different models for Power Quality disturbances are developed using Matlab – Simulink and graphical user interface for users. These models are including three-phase sources, three-phase breaker for removing large load to simulate the voltage swell and three-phase fault and removal large load are used for simulation of voltage sag, three phase nonlinear loads are used for to simulate unbalance voltage, permanent there-phase fault for simulation model of interruption and converter with a source impedance for voltage notch system models are gave with the results of the models
