This paper explores the performance of alternative voltage control strategy applied to direct drive synchronous wind generators, more specifically with permanent magnetic (PMSG). The reactive power control of the grid-side converter is investigated for voltage control purposes. In Brazil, the Grid National Operator (ONS) requires that wind turbines stay connected to the grid during voltage dips, but...
The paper investigates the possibility of ranking synchronous generators in a power system according to their contribution to system angular and voltage stability. The aim of this research is to establish fast semi-analytical methodology, i.e., avoiding transient simulations, to determine which synchronous generators can be safely disconnected from the network or replaced by other types of generators,...
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...
Compared with the doubly-fed AC excited wind-power generation system, the directly-driven permanent magnet synchronous generator (PMSG) for wind-power system has advantage of simpler structure, higher generation efficiency and more reliable operation. To solve the weakness associated with the traditional id=0 control scheme, such as relatively large power rating for generator-side converter and correspondingly...
Permanent magnet synchronous generation (PMSG) has been more and more used in the wind power generation system due to its advantage of simpler structure, higher generation efficiency and more reliable operation. However, the behavior of wind power system during grid disturbances becomes more important with an increasing amount of wind energy installed. Nowadays the grid code demands that the wind...
Since variable-speed generation has a higher energy capturing and converting efficiency than the fixed-speed system, new proposals for wind power system utilize variable-speed generators are introduced, among which permanent-magnet synchronous generator(PMSG) is an attractive choice. This paper describes a sensorless vector control strategy for a direct-driven PMSG, which is connected to the power...
