Load angle estimation of synchronous generator

Determination of Load Angle for Salient-pole Synchronous Machine

This paper presents two methods for load angle determination for salient-pole synchronous generator. The first method uses optical encoder to detect the rotor position. In some cases the end of the rotor shaft is not free to be used and mounting of an encoder is impossible. Therefore, the second method proposes estimation of the load angle based on the measured electrical values that have been ...

Synchronous Generator Model Identification and Parameter Estimation From Operating Data

A novel technique to estimate and model parameters of a 460-MVA large steam turbine generator from operating data is presented. First, data from small excitation disturbances are used to estimate linear model armature circuit and field winding parameters of the machine. Subsequently, for each set of steady state operating data, saturable inductances and are identified and modeled using nonlinea...

Control and stability improvement of combined wind-battery system with permanent magnet synchronous generator supplying active load

This paper deals with the control and stability enhancement of a wind power generation system feeding active load with constant power characteristic. The under study system is a combined wind-battery generation system with permanent magnet synchronous generator (PMSG) supplying active load by using interfaced power electronics converters. The employed active load is indeed an active rectifier b...

Artificial Neural Networks applied to Measurements Rotor Angle in a Synchronous Generator

This work analyzes the advantages of Artificial Neural Networks applied in development of a technique for estimation rotor angle and speed, transient stability assessment and control in real-time in Synchronous Generator. Two multi layered feed-forward Artificial Neural Networks are used for this technique. One is used for the estimation of rotor angle and another for the estimation of rotor sp...
