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...
Back to back full-size PWM converter is widely used in direct drive wind power system (DDWPS). It is the most cost-effective converter topology verified in field application. The characteristics of back to back full-size converter of DDWPS based on permanent magnetic synchronous generator (PMSG) are researched on in detail through a precise simulation and an experiment. The control strategy is given...
This paper discusses a control strategy of direct-drive permanent magnet wind power system, and proposes back-to-back PWM converter control method that PWM technology is employed both in generator-side and grid-side. The system consists of permanent magnet synchronous generator (PMSG), PWM rectifier in generator-side, intermediate DC circuit, and PWM inverter in grid-side. DC voltage control is used...
