Abstract:

Abstract In this paper a system of a grid side and a generator side converters, both working with a common capacitor, is presented. The 6-phase asymmetric inset-type SMPMSM generator is used. A large pole pair number of this generator enables a gearless wind turbine operation. The fundamental and 3rd harmonic cooperation is used to increase the generator performance. This is accomplished by means of the 3rd harmonic current injection. For that reason the generator side converter must have a neutral connection.

Abstract:

Five-phase induction generators in variable-speed wind energy systems are a focus of this study, and a unique method of regulating them utilizing indirect vector control is proposed in wind energy systems. Grid-side regulation is handled by a two-level converter, whereas machine-side control is handled by a five-phase three-level converter. There are five electrically distinct phases in ASG, and each one is 720 apart. More power can be generated in the same machine frame with this configuration than with a normal three-phase induction generator, and the system is also more stable and sturdier.

Brushless doubly-fed induction generators have higher reliability, making them an attractive choice for not only offshore applications but also for remote locations. These generators are composed of two back-to-back voltage source converters, a grid side converter and a rotor side converter. Existing techniques use the rotor side converter for reactive current control; however, it is more suitable for stabilizing steady state behavior. In order to stabilize the voltage fluctuations at the point of common coupling (PCC) due to sudden inductive load introduction, the grid side converter may be a

Abstract:

Switch open fault characteristics and simple diagnosis scheme in a back-to-back converter are presented for a permanent magnet synchronous generator (PMSG) based variable-speed grid-connected wind power conversion. In the back-to-back converter, the failure in switching devices may occur either in a machine side converter (MSC) or in a grid side converter (GSC), which decreases the generator output power and degrades the stability in wind power generation system. To detect such a fault, the second-order harmonic components of the q-axis current are monitored in the MSC as well as in the GSC. T

Abstract:

This paper proposes a low voltage ride through (LVRT) scheme of doubly fed induction generator (DFIG) based on the supercapacitors energy storage. The novel control strategy of the bi-directional converter and the grid side converter is established. Simulation model of the DFIG system is developed. Simulation results show that the presented scheme can efficiently reduce the DC-link overvoltage, supply reactive power to the power system through grid side converter, and help grid recovery under system fault, improving the LVRT capability of the system.

Abstract:

Low-voltage ride-through (LVRT) and grid support capability are becoming a necessity for grid-tied renewable energy sources to guarantee utility availability, quality and reliability. In this paper, a swap control scheme is proposed for grid-tied permanent magnet synchronous generator (PMSG) MW-level wind turbines. This scheme shifts system operation from maximum power point tracking (MPPT) mode to LVRT mode, during utility voltage sags. In this mode, the rectifier-boost machine-side converter overtakes DC-link voltage regulation independently of the grid-side converter. The latter attains gri

Abstract:

The most widely used generator type is the Doubly-Fed Induction Generator (DFIG). Because of the close coupling of the generator and the gird, the stator flux of DFIG is distorted while the Grid voltage dip happens. To achieve the LVRT, the LVRT control strategy of DFIG, especially the association of gird side and rotor side converter, is discussed under gird voltage dips. Simulation and experiment have been implemented to prove the idea.

The article presents an induction generator connected to the power grid using the AC/DC/AC converter and LCL coupling filter. Three-level inverters were used in the converter, both from the generator side and the power grid side. The algorithm realizing Pulse Width Modulation (PWM) in inverters has been simplified to the maximum. Control of the induction generator was based on the Direct Field-Oriented Control (DFOC) method. At the same time, voltage control has been used for this solution. The MPPT algorithm has been extended to include the variable pitch range of wind turbine blades. The act

Nowadays, multiphase machine drives are considered in many applications, especially for medium and highpower applications. This paper focuses on the topology of the six to three phase (hexaphase) indirect matrix converter (IMC). The matrix converter (MC) is designed based on twelve bidirectional switches for the rectifier stage and six single switches for the inverter stage. It is interfaced to a high-performance, fault-tolerant multiphase permanent magnet synchronous generator (PMSG) on one side and to the grid on the other side.

This paper presents a performance enhancement of a permanent magnet synchronous generator (PMSG) system with control of generator-side converter for a wind turbine application. This method uses zero d- axis stator current control to minimize winding losses of the generator.

Abstract:

Developing a low-cost power converter for small-scale wind turbine systems using permanent magnet synchronous generators (PMSG) is one of the hot topics in the wind power generation research. Using minimum number of switches with high efficiency is the target of this proposal. The proposed converter consists of six-switches in the generator and grid side. The DC-link side is divided into two capacitors with mid-point to connect the third phase of the PMSG to this point. The topology and the control strategy is implemented and the validity of this topology is validated by using PSIM software.

The control strategy minimizes quality functions, which represent the desired behavior of the converter. The technique developed uses predictive direct power control to control the rotor and grid side converter. The main advantages of this method are no need of linear controllers, coordinates transformations or modulators for converter and inverter.
