Monitoring of Electrical Quantities on Generator in HEPP Peruca

Abstract

The electrical quantity monitoring system installed on generator 1 in HPP Peruca is described. The system is defined to monitor quantities that are relevant for the generator’s behavior in stationary and dynamic states: armature voltages and currents, excitation voltage and current, rotor rotation angle and field in the air gap. Two independent systems were installed and investigated for measuring the rotor rotation angle (measurement using an encoder, or using a magnetic sensor), and two independent procedures for determining the load angle were defined. The signal of the loop flux of the measuring coil in the air gap allows for the identification of the stray reactance of the armature winding. The selection of the identification procedure requires further theoretical and experimental research. The modernly designed continuous monitoring system in HPP Peruca, with the development of appropriate software support, provides the possibility for on-line identification of the parameters of the synchronous generator and the equivalent network using a standard estimation algorithm. The article describes some experiences and gives the results achieved in the development of the monitoring system installed on the generator at HPP Peruca.
