The Multiple Power Quality Disturbance Classification Based on Power System Time Domain Analysis

Multiple power quality disturbances classification methods mostly are based on the analysis of the disturbance mathematical expressions. This paper presents a method of multiple power quality disturbances classification and evaluation which is based on the analysis of IEEE 9 nodes system. The method resolves the problem that the existing algorithms can´t reflect the power system parameters and if there´s any change in the power system. An IEEE 9 nodes standard model is built by Simulink and all the usual complex power disturbances are simulated in the model. These disturbances are all classified and evaluated by the method of time domain characteristic analysis accurately. The simulation results shows that this method can also be used in the power disturbance classification based on power system. And it can also reflect the system´s parameters.
