KONCAR-Institute-Load Angle and Power Measurement System - 2

LOAD ANGLE & POWER MEASURMENT SYSTEM Web HMI (real time data, trends, spectrum, alarms ) One of the key parameters of the generator, in sense of control and stability protection, is the angle of the induced voltage internal to the generator (load angle). Current practice is to estimate this value using measurements from the terminals of the generator and mathematical models. Load Angle & Power System (LA&P) enables direct measurement of the generator load angle based on key phasor and electrical values measurement of the generator. Besides load angle measurement, LA&P system enables...
