“…In 1968, the IEEE Excitation Modeling Subcommittee introduced guidelines for the excitation systems in use at that time, which would include a standard nomenclature and criteria for those models [2]. New models were launched in 1981 which reflected facilities improvements and improved quality standards.…”

This paper involves the characterization and the performance evaluation of various types of synchronous generator excitation systems in the transient stability enhancement of power systems. The Investigations are carried out by modelling the typical DC, AC and static excitation systems represented by IEEE types DC1A, DC2A, AC4A, AC5A, ST1A and ST2A attached with a generator connected to the infinite bus. The performance evaluation of these excitation systems is performed in terms of their response ratio and ceiling voltage together with the system settling time and the critical clearing time following a sudden three-phase short-circuit in the system. Each excitation system together with its power system stabilizer is considered in the analysis. 4th order Runge Kutta method is utilized for transient stability analysis of the power system with the 3rd order model for synchronous generator representation. The investigations reveal that the IEEE ST2A Excitation System is better than the other types of excitation systems.

“…Hooke and Jeeves method is used to determine the machine variables. A more detailed discussion of some excitation control systems for brushless synchronous generators is presented in [5]- [7], and different methods of voltage regulation in generators are proposed in [8]- [10]. In this context, the objective of this paper is to present and discuss the results obtained from the modeling, construction and testing of a synchronous generator with asynchronous excitation (SGEA) and with an uncontrolled rectified bridge.…”

This paper presents the main features of design, construction, performance analyses and experimental studies of a brushless self-excited three-phase synchronous generator. The basic construction, principle of operation, and exciting characteristics are described. In proposed machine the rotor winding is shorted through diodes and the self-excitation is reached by a slip between rotor and stator winding built with different pole numbers. Computer simulations performed with MATLAB® software were used to verify the mathematical model of the brushless self-excited synchronous generator and the achieved results showed similar behavior with experimental values.

“…THE DESIGN OF TWO CLOSED LOOP EXCITATION CONTROLLERWe can see the structure chart of two closed loop excitation controller fromFigure 3. The controller consists of AVR, ACR, PWM, circuit of voltage signal sampling and circuit of current signal sampling; the driver is made of pulse amplifying circuit and power switch; protection circuit consists of over voltage protection circuit and low speed protection circuit[4][5].The process of automatic excitation regulatory system is: if the generator voltage drops voltage detection amplify error signal output of voltage regulator increases output of current regulator increases pulse width increases excitation voltage of exciter increases voltage output of exciter increases exciting current of generator increases output voltage of generator increases. When voltage of generator is increasing, the adjusting process is contrary to what aforementioned.…”

Aiming at the characteristic of excited single-phase brushless synchronous generator, it is analyzed that the single closed-loop excitation regulator has a defect that its output voltage is reducing with increasing load. Using double closed loop speed regulation system of DC motor for reference. Design a new type regulator which has a excitation current inner loop and voltage outer loop, and use PWM method to regulate excitation current. Based on mathematic model and design target of the diesel generator and voltage regulation of generator's steady and dynamic state, Current and voltage regulator are designed by typical link which is known by relation of target and parameter. The test result shows that the whole system has advantage that is regulating voltage precision and fast response. The voltage regulator is designed by engineering method, and it meets the requirements after correcting.
