Improved Voltage Sag Ride-Through for Line-Connected Synchronous Machines
In this paper, the voltage sag ride-through capabilities of the line-connected electrically excited synchronous machine with damper windings (EESM) is investigated. We will design an algorithm for voltage sag ride through by controlling the flux. Two aspects are investigated, first the capability to keep the nominal speed and second the damping of speed oscillations. We will show through simula...
متن کاملVoltage Sag Ride-Through of AC Drives: Control and Analysis
This thesis focuses on controller design and analysis for induction motor (IM) drives, flux control for electrically excited synchronous motors with damper windings (EESMs), and to enhance voltage sag ride-through ability and analysis for a wind turbine application with a full-power grid-connected active rectifier. The goal is to be able to use the existing equipment, without altering the hardw...
متن کاملImprovements to Voltage Sag Ride-through Performance of Ac Variable Speed Drives
Voltage sags originating in ac supply systems can cause nuisance tripping of variable speed drives (VSDs) resulting in production loss and restarting delays. In ac VSDs having an uncontrolled rectifier front-end, the effects of voltage sags on the dc link causing dc under-voltage or ac overcurrent faults initiate the tripping. This paper suggests modifications in the control algorithm in order ...
متن کاملLow Voltage Ride-Through Capability Improvement of Doubly Fed Induction Generator using DVR and SMES
Abstract: With the growth of communities and the increasing need for electricity, and because of the many benefits of renewable energy sources, the wind turbine has become a completely commercial and inevitable process, with increasing penetration into the electricity grid. Distribution networks, on the other hand, are subject to fault that cause power fluctuations and outflow of wind units. In...
متن کاملVoltage Sag Ride through Improvement of Modern Ac Drives: Review of Methods and a Case Study
ABTRACT Modern solid-state induction motor drives are highly sensitive to voltage sags. Their nuisance tripping can cause long re-start delays and production losses. Although it is the supply utility’s responsibility to maintain a good quality supply system, drives manufacturers also have to take steps to harden the performance so that a drive stays on line as long as possible during a voltage ...
