Fault Ride-Through Capability of Voltage-Controlled Inverters

IEEE Transactions on Industrial Electronics, 2018
An auxiliary voltage controller is proposed for the fault ride-through (FRT) control of voltage-controlled inverters used in distributed energy resources. The proposed auxiliary controller can be added to different existing voltage control strategies with minimum or no need to alter the original structure of the voltage controller.

A DC Solid-State Transformer With DC Fault Ride-Through Capability

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
This paper investigates a dc solid state transformer (DCSST) with dc fault ride-through (FRT) capability for medium voltage dc (MVDC) systems. The fault ride through requirement for DCSST in dc gird is investigated. Short circuit fault clearance on the medium voltage (MV) side is realized by introducing full bridge converters with cascaded dc converter

Fault Ride-Through Capability Enhancement by using Fuzzy Control

Power and Energy Systems, 2012
This paper proposes a fuzzy controller for improving Fault Ride-Through (FRT) capability of Doubly Fed Induction Generator (DFIG) based Wind Turbines (WTs). The controller is designed in order to compensate the voltage at the Point of Common Coupling (PCC) by regulating the reactive and active power generated by WTs simultaneously.

Fault Ride Through Capability for Solar Inverters

EPE Journal, 2012
AbstractA solar inverter for utility scale has been developed in this paper, and the inverter has fault ride through (FRT) capability, which is now discussed in Japan and similar to requirement in U.S.A and Europe. This solar inverter consists of a boost chopper and a three-phase 2-level inverter, and the capacity covers from 20 kW to 600 kW.

An enhanced MMC topology with DC fault ride-through capability

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
High-voltage direct current system using modular multilevel converter (MMC-HVDC) is a potential candidate for grid integration of renewable energy over long distances. The dc-link fault is an issue MMC-HVDC must deal with. This paper proposed an enhanced MMC topology with dc fault ride-through capability.

Fault ride-through capability of DFIG wind turbines

Renewable Energy, 2007
This paper concentrates on the fault ride-through capability of doubly fed induction generator (DFIG) wind turbines. The main attention in the paper is, therefore, drawn to the control of the DFIG wind turbine and of its power converter and to the ability to protect itself without disconnection during grid faults. The paper provides also an overview on
