“…The resistors also dissipate part of the generated power thus avoiding rotor overspeed. A low value of the resistance, as well as its fast insertion once fault occurs and for a short duration as possible, leads to improved DFIG stability [13,[63][64][65][66].…”

There is increased worldwide wind power generation, a large percentage of which is grid connected. The doubly fed induction generator (DFIG) wind energy conversion system (WECS) has many merits and, as a result, large numbers have been installed to date. The DFIG WECS operation, under both steady state and fault conditions, is of great interest since it impacts on grid performance. This review paper presents a condensed look at the various applied solutions to the challenges of the DFIG WECS including maximum power point tracking, common mode voltages, subsynchronous resonance, losses, modulation, power quality, and faults both internal and from the grid. It also looks at approaches used to meet the increasingly stringent grid codes requirements for the DFIG WECS to not only ride through faults but also provide voltage support. These are aspects of the DFIG WECS that are critical for system operators and prospective investors and can also serve as an introduction for new entrants into this area of study.

Electric power conversion system (EPCS), which consists of a generator and power converter, is one of the most important subsystems in a direct-drive wind turbine (DD-WT). However, this component accounts for the most failures (approximately 60% of the total number) in the entire DD-WT system according to statistical data. To improve the reliability of EPCSs and reduce the operation and maintenance cost of DD-WTs, numerous researchers have studied condition monitoring (CM) and fault diagnostics (FD). Numerous CM and FD techniques, which have respective advantages and disadvantages, have emerged. This paper provides an overview of the CM, FD, and operation control of EPCSs in DD-WTs under faults. After introducing the functional principle and structure of EPCS, this survey discusses the common failures in wind generators and power converters; briefly reviewed CM and FD methods and operation control of these generators and power converters under faults; and discussed the grid voltage faults related to EPCSs in DD-WTs. These theories and their related technical concepts are systematically discussed. Finally, predicted development trends are presented. The paper provides a valuable reference for developing service quality evaluation methods and fault operation control systems to achieve high-performance and high-intelligence DD-WTs.

Resumo -Devido à crescente participação da energia eólica nas redes elétricas, códigos de rede de muitos países requerem que sistemas de conversão de energia eólica permaneçam conectados durante afundamentos de tensão, entregando potência e participando do controle dos níveis de tensão da rede. Para turbinas eólicas baseadas no gerador síncrono de ímã permanente, a estratégia mais utilizada para satisfazer esse procedimento é o controle das potências ativa e reativa entregues à rede em conjunto com o braking chopper, em que o controle de potência é do tipo proporcional-integral. Neste trabalho, propõe-se a utilização desta estratégia com uma modificação na malha de controle da potência ativa, visando a ampliação da suportabilidade a afundamentos de tensão. Testes da modificação proposta são realizados a partir da modelagem e simulação no Matlab/Simulink de um sistema de conversão de energia eólica conectado a um alimentador de distribuição.Palavras-chave -Afundamentos de Tensão, Controle PI Modificado, Energia Eólica, Gerador Síncrono de Ímã Permanente. PMSG-BASED WIND TURBINE GRID-SIDE CONTROL MODIFICATION TO IMPROVE THE LOW-VOLTAGE RIDE-THROUGH CAPABILITYAbstract -Due to the increasing wind power grid penetration, grid codes of many countries require wind energy conversion systems to continue grid-connected during voltage sags, delivering power and aiming the control of system voltages. For permanent magnet synchronous generator-based wind turbines, conventional strategy to do low-voltage ride-through is the active and reactive power control in connection to the braking chopper, where the power control is of the proportionalintegral type. In this work, an active power control loop modification is proposed from the conventional strategy in order to improve the low-voltage ride-through capability. Tests of the proposed modification are carried out through Matlab/Simulink modeling and simulation of a wind energy conversion system connected to a distribution feeder.
