The double-fed induction generator wind turbine has recently received a great attention. The steady state performance and response of double fed induction generator (DFIG) based wind turbine are now well understood. This paper presents the analysis of stator and rotor flux linkage dq models operation of DFIG under different faults and at different locations.
The doubly fed induction generators (DFIGs) are used in almost 50% of the offshore and onshore wind power plants. The DFIGs offer advantages compared to fix speed induction generators. The DFIGs are sensitive to grid voltage disturbances and require additional protection for the rotor side power electronic converter, like crowbar protection. In the present paper two active crowbar topologies are compared,...
An important aspect of wind power plant (WPP) impact studies is to evaluate the short circuit (SC) current contribution of the plant into the transmission network under different fault conditions. This task can be challenging to protection engineers due to the topology differences between different types of wind turbine generators (WTGs) and the conventional generating units. This paper presents simulation...
In this paper, the authors propose an algorithm to react to fault in the grid, this is based in block control scheme using sliding modes, for a double fed induction generator. In normal operation the electric torque and reactive power be controlled; when a fault occurs the electric torque and the stator current is controlled. The applicability of the proposed scheme is tested via simulations.
Distributed resources are connected to distribution feeders using synchronous generators, induction generators, or power electronic converters. Models of these interface technologies are developed for use with an open-source distribution system simulator. Test cases and examples are presented for voltage control, short circuit, and dynamic analysis. This modeling level is appropriate for distribution...
In this paper, a model-based strategy for stator-interturn short-circuit detection on induction motors is presented. The proposed strategy is based on the generation of a vector of specific residual using a state observer. The vectorial residual is generated from a decomposition of the current estimation error. This allows for a fast detection of incipient faults, independently of the phase in which...
