Bad data analysis and detection using PMU with UPQC integration to grid during fault conditions

<span lang="EN-US">Analysis of bad data in an IEEE 14 bus system with <a name="_Hlk121211016"></a>phasor measuring units (PMU) devices is carried out this paper. The normal operating condition achieved from the PMU compared to during faults system. A principal component analysis (PCA) technique proposed paper for distinguishing difference between transmission and fault conditions. PCA approach detects dynamical magnitudes measurements taken also determines noise caused by disturbances. grid updated unified power quality conditioner (UPQC) improvising parameters mitigate fault. use a comparative measured components analyzing performance under different simulation these modules Simulink environment MATLAB software done concerning time.</span>
