Control of a hybrid excitation synchronous generator connected to a diode bridge rectifier supplying a DC bus in embedded applications

Abstract

This study deals with the modelling and the control of the hybrid excitation synchronous machine connected to a diode bridge rectifier. The set operates as a DC generator that supplies an isolated grid in embedded applications such as aircraft electrical power generation. The elaborated model includes the magnetic circuit saturation effect. The aim of the control is to maintain the DC bus voltage constant when the load and/or the speed of the rotor vary. Simulation results and experiments validate the approach. The electrical parameters of the laboratory prototype machine are identified prior to the control test.

A review of power electronics equipment for all-electric ship MVDC power systems

“…The easiest solution is the employment of a diode rectifier if voltage regulation is possible by means of the excitation control of synchronous machines [41,42] or hybrid excitation synchronous machines [43,44]. This solution has many positive features such as simplicity, reliability, efficiency and low cost.…”

High Performance Reduced Order Models for Wind Turbines with Full-Scale Converters Applied on Grid Interconnection Studies

“…The modeling of this control considers the delay caused by the thyristors, the field and damping winding time constants. Two Proportional-Integral (PI) controllers can be used, where the outer DC voltage loop gives a reference to an inner current loop that controls the voltage applied in the field winding [24]. In this work, the field voltage is assumed to be constant, because during voltage dip, the machine is decoupled from the grid and, also, wind speed is considered with slow variations.…”

Hybrid excitation synchronous machine finite simulation model based on experimental measurements

“…For control purpose, the conventional Park first harmonic model, commonly used to represent rotating machines, can be used [11,12]. However, this model does not accurately describe the HESM responses.…”
