“…That is why, the researchers in this field have been trying to design a controller that drives the two control inputs; the field excitation and the fuel input, simultaneously, since it is believed that if the two input controls are coordinated, the performance of the controller under peculiar situations such as the one explained in McCowan et al (2003) will be improved. Rahman et al (1996) proposed a non-linear model of the isolated permanent magnet synchronous generator driven by a Diesel engine. Then, the non-linear model was linearised around steady-state values.…”

“…Further, a performance index was suggested to find an optimal controller to regulate the terminal voltage and frequency, where they used two control inputs; the fuel mass to control the torque of the engine, and the firing angle of a thyristor to control the terminal voltage, Rahman et al (1996). Although Rahman et al (1996) used a first order model of the Diesel engine, the simulations presented showed the effectiveness of the proposed controller. Then, Goh et al (2003) proposed a sliding-mode speed controller of the Genset.…”

A generating set (Genset) comprises a prime mover such as a Diesel Engine, and a synchronous generator. The most important controllers of such systems are the speed governor to regulate the engine or shaft speed and the automatic voltage regulator (AVR) to regulate the terminal voltage. The speed governor is a PID controller that uses the difference between the speed and its desired value as a feedback signal to change the fuel mass input by changing the fuel rack position. AVR is also a PID that uses the difference between the terminal voltage of the generator and its desired value, and changes it by manipulating the voltage of the field excitation circuit. Thus, the two controllers act separately. That is to say, if the speed varies from the desired value, the speed governor will react, while the AVR will not react as long as the voltage is stable, and vice versa. In this work, a control-oriented model is suggested for a Genset, and then a controller, that regulates the shaft speed and the terminal voltage, is designed by feedback linearisation. The proposed controller has two inputs: the fuel mass and the field circuit voltage. Simulations show that the proposed controller makes the two inputs act, simultaneously. Thus, any change of the speed e.g., forces the two input controls to react, in contrast to the ordinary PID controllers. Further, we discuss the robustness of the proposed controller to uncertainties and time delay.

“…It is due in large part to its cost effectiveness and high reliability. In particular, the application of direct-driven Permanent-Magnet Synchronous Generation (PMSG) WPGS is a trend in the development of WPGS applications, especially in offshore and home scale WPGSs [4]- [9]. As a result, in order to decouple the speed of a PMSG from a grid, especially when all of the energy should go through the grid interface system [10], [11], the demand for power electronic devices with a higher rating at a lower cost has risen, as shown in Fig.…”

Permanent-Magnet Synchronous Generators (PMSGs) are used widely in Wind Power Generation Systems (WPGSs), and the Vienna rectifier was recently proposed to be used as the generator-side converter to rectify the AC output voltage in PMSG-based WPGS. Compared to conventional six-switch two-level PWM (2L-PWM) converters, the Vienna rectifier has several advantages, such as higher efficiency, improved total harmonic distortion, etc. The motivation behind this paper is to verify the performance of direct-driven PMSG wind turbine system based-Vienna rectifier by using a simulated direct-driven PMSG WPGS. In addition, for the purpose of reducing the reactive power loss of PMSGs, this paper proposes an induced voltage sensing scheme which can make the stator current maintain accurate synchronization with the induced voltage. Meanwhile, considering the Neutral-Point Voltage (NPV) variation in the DC-side of the Vienna rectifier, a NPV balancing control strategy is added to the control system. In addition, both the effectiveness of the proposed method and the performance of the direct-driven PMSG based-Vienna rectifier are verified by simulation and experimental results.

: This paper presents the dynamic analysis of load following performances of split-shaft microturbine generator (MTG) and Diesel Generator systems considering P-I type load following and P-I type speed controllers under stand-alone mode of operation. In this paper microturbine system coupled with a synchronous generator (SG) is considered. The dynamic performances of split-shaft MTG and Diesel Generator system are also examined when they are connected together to satisfy the load demand. Finally, the MTG and diesel generator systems are connected to an 11 kV rural distribution network to examine the transient behaviour during active power injection. Simulation result for all the cases are analyzed and presented in this paper.
