Wound-field synchronous machines (WFSMs) are included in the majority of large power generating units and special high-power motor drives, due to their high efficiency, flexible field excitation and intrinsic flux weakening capability. Moreover, they are employed in a wide range of high-end solutions in the low-to-medium power range. This contribution presents a comprehensive survey of classical and modern methods and technologies for excitation systems (ESs) of WFSMs. The work covers the fundamental theory, typical de-excitation methods and all the modern excitation equipment topologies in detail. It also includes a description of the state-of-the-art and the latest trends in the ESs of wound-field synchronous motors and generators. The purpose of the paper is to provide a useful and up-to-date reference for practitioners and researchers in the field.

This article proposed a position signal-free field current estimation method for brushless synchronous starter/generator (BSSG). Generally, the estimation of the field current of BSSG depends on the position signals provided by a physical sensor or position estimation algorithm. However, there are risks in using the traditional method when the position sensor is broken or using estimated position information to evaluate the field current. To overcome this problem, this paper proposes a position signal-free estimation method. In this method, the mathematical relationship between the field current of the main machine (MM) and the current vector modulus (CVM) of the main exciter (ME) rotor currents are analyzed. The theoretical findings reveal that the average field current of the main machine (MM) equates to the minimum or √3/2 times the maximum of ME's rotor CVM in both rotating and stationary coordinates. Since the ME's rotor CVM is independent of the rotor position information, the estimation of the field current of BSSG can be achieved without the rotor position signal departing in. Finally, an experiment platform is established to emulate the BSSG, and experimental results validate the theoretical findings.

Brushless power generation sets are a technology of choice for on‐board power generation in aerospace and marine applications, emergency and backup power systems, etc. Efficient modelling of these systems is necessary for various purposes such as design, analysis, control and specially condition monitoring. An accurate and efficient model of a diesel‐engine generator‐rectifier system consisting of a three stage brushless synchronous generator is presented. The constant parameter voltage‐behind‐reactance model of the pilot exciter (PE), main exciter (ME) and main generator are derived and integrated to form a unified model suitable for efficient simulation of a diesel‐engine brushless generation system. Simulation studies are carried out in MATLAB using PLECS toolbox and the results are compared to experimental results to verify the performance of the proposed integrated model.
