The precise information of permanent-magnet synchronous generator (PMSG) rotor position and speed is essentially required to operate it on maximum power points. This paper presents an adaptive network-based fuzzy inference system (ANFIS) for speed and position estimation of PMSG, where an ANFIS-based model reference adaptive system is continuously tuned with actual PMSG to neutralize the effect of...
This paper introduces a study for the small wind energy conversion system (WECS), which aims to select the optimum design parameters to achieve high performance system. The main features of the studied system are high efficiency, operation at maximum power point tracking (MPPT) and long battery lifetime. The Permanent Magnet Synchronous Generator (PMSG) operates at variable wind speed and it is connected...
During recent years the market for small wind turbine generators (SWTG) has been continuously growing. In this context, the supply of components for this product has also been increasing. The main components of SWTG are the rotor, the generator and the wind energy conversion system (WECS), typically formed by a rectifier plus an inverter. The settings of WECS affect the SWTG behaviour, especially...
This paper presents the performance analysis of a variable speed wind energy conversion system that employs permanent magnet generator (PMG) coupled to horizontal axis wind turbine. The study involves a computer simulation of the wind turbine driven PMG connected to the grid through an inverter. The switching signal for the PWM inverter has been generated by a method of DC link voltage control adopted...
The recent development of power electronic technology encourages to use variable speed wind turbine (VSWT) driving a doubly fed induction generator (DFIG), wound field synchronous generator (WFSG) or permanent magnet synchronous generator (PMSG) for wind power generation. Among those, stability analysis of DFIG type of VSWT has already been reported in many literatures. On the other hand, stability...
This paper presents a model of a wind turbine-fed interior permanent magnet synchronous generator (IPMSG) connected to converter middot inverter drive system. Control inputs are defined as a torque of a wind turbine and the converter voltages and inverter voltages of the IPMSG drive. The drive system becomes a multi-input and multi-output controlled object. Variable control objects such as maximum...
