Modeling and control of diode rectifier fed PMSG based wind turbine

Abstract

This paper analyzes and models Permanent Magnet Synchronous Generator (PMSG) based wind turbine with diode rectifier + boost converter + PWM inverter based power electronic interface, and proposes corresponding control strategy that is capable of maximum power point tracking (MPPT), reactive power regulation and fault ride through (FRT) capability. Using DIgSILENT/Power Factory 14.0, simulations are carried out to show the superior features of such wind turbine and the validity of proposed control strategy.

A review of low-voltage ride-through enhancement methods for permanent magnet synchronous generator based wind turbines

“…The advantages of this structure are low cost and simple control structure as shown in Fig. 13 [60,68,70]. In [60], as shown in Fig.…”

“…In [68], the duty ratio for the BC switch is built by the dc-link voltage error after passing through PI controller ( Fig. 13(b)).…”

“…In some papers, a Braking Chopper (BC) or active crowbar system is proposed to be placed in dc-link to dissipate the active power during the grid faults [60,[66][67][68][69]. Braking chopper consists of a high power resistor with a series switch as shown in Fig.…”

“…The two foremost types of LVRT capability enhancement methods are external devices based methods and modified controller based methods. Energy Storage Systems (ESSs) , Braking Chopper (BC) or active crowbar system [66][67][68][69][70], FACTS devices [71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87][88][89][90] and some other methods such as Series Dynamic Breaking Resistor (SDBR), electronic on Load Tap Changer (OLTC) [91][92][93][94][95] are popular methods for LVRT capability enhancement using external devices. Pitch Angle Control (PAC) [96][97][98][99] and modified back-to-back converter controllers [100][101][102][103][104][105][106][107][108] are modified controller based methods.…”
