New possibilities of hydrogenerator analysis based on electrical quantities monitoring

Abstract

The article describes a system for continuous monitoring of electromagnetic quantities of a hydrogenerator, which includes: armature voltages and currents, excitation voltage and current, air gap field and rotor rotation angle. The monitoring system is designed so that, in addition to monitoring individual quantities, it represents the basis for on-line parameter identification and analysis of a synchronous generator. The procedures for: measuring the load angle, identifying the voltage and reactance of the equivalent network, determining the stray reactance of the armature winding and identifying the main reactance in the longitudinal and transverse axes of the synchronous machine are described.
