In this work, we are interested in the experimentation of an autonomous wind energy conversion system (WECS) using a test bench emulating a variable speed wind turbine (VSWT). This wind generator is connected to isolated loads through a DC bus and an inverter. The regulation of the DC bus voltage is carried out by a DC load controlled by a chopper. The goal of our work is to show the load voltage...
In this paper, a novel grid integration system for a variable-speed wind turbine using an interior permanent-magnet synchronous generator (IPMSG) is developed. The power conditioner system (PCS) consists of a series-type 12-pulse uncontrolled diode rectifier powered by a phase-shifting transformer and then cascaded to a pulsewidth-modulated (PWM) voltage source inverter. The active current of the...
Wind power is one of the common distributed generation in microgrid. According to the requirements of microgrid, permanent magnet synchronous wind generator (PMSWG) for wind energy distributed generation was designed in this paper and it has simple structure, easy control and low cost characteristics, non-controllable rectifier and grid-connected PWM convertor is adopted as the AC grid-connected circuit...
Microturbine generator system is one of the most promising distributed generation systems because it is small, efficient and mobile. When it is running, the high-frequency alternating current of permanent magnet synchronous generator generating must be rectified and inverted into 50Hz AC to meet the user requirements. Normally, the diode rectifier is used. When we need to regulate voltage, the DC/DC...
In this paper, a novel grid integration system for a variable-speed wind turbine using Interior Permanent Magnet Synchronous Generator (IPMSG) is developed. The power-conditioning system consists of a series-type 12-pulse diode rectifier powered by a phase shifting transformer and then cascaded to a PWM voltage source inverter.

This paper proposes a control strategy for tracking and maintaining a constant voltage and frequency across remote loads through stand alone variable speed wind energy conversion system (VSWECS). The system consists of a variable speed wind turbine coupled to a permanent magnet synchronous generator (PMSG). Output of the PMSG is first converted into a fixed DC voltage using a buck chopper. The control...
This paper proposes a low-cost power converter for micro wind turbine systems using permanent magnet synchronous generators (PMSG). The proposed converter consists of a two-leg three-phase PWM inverter for the generator control and a single-phase half-bridge PWM converter which is connected to the utility grid. For the two separate DC-link voltages, a balancing control is added and the adverse effect...
