Abstract
This paper utilizes several mathematical techniques based on the method of minimizing least squares to integrate synchronized measurements and power system operations planning data. The intent is to use several measurements and system data to enhance the overall accuracy of measurements in a power transmission system, thus integrating the calibration process. The techniques used include a least squares estimator, the Newton Raphson method to attain low discrepancies between measurements, and the least squares method to match measurements made simultaneously (e.g., obtained from phasor measurement units). A novel process is proposed which is applicable in real-time synchronized measurements calibration.
