Tuning harmonic absorption of voltage source converters

Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010
This paper develops a tool for controlling the harmonic absorption of hysteretic controlled voltage source converters that are connected to a power system. Each VSC is controlled by a state feedback control input to a hysteretic comparator. A suitable model of the converter is first developed by including the state feedback gains and hysteretic ...

Autonomous Load Sharing of Voltage Source Converters

IEEE Transactions on Power Delivery, 2005
An autonomous load-sharing technique for parallel connected three-phase voltage source converters is presented. An improved power-frequency droop scheme computes and sets the phase angle of the voltage source converter (VSC) directly to yield more rapid real power sharing without sacrificing frequency regulation.

Adaptive control of a Voltage Source Converter

CCECE 2010, 2010
This work presents a new trajectory tracking control strategy for a three phase Voltage Source Converter (VSC). The design is based on a third order nonlinear model of the VSC expressed in the dq frame. By suitable approximation of the dc voltage dynamics, the system is transformable to a LTI form by a nonlinear change of state coordinates.

Vectorial control of a Voltage Source Converter

2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA), 2010
The Voltage Source Converter (VSC) offers the possibility of full four quadrant operation and the total control active and reactive power with the minimal generation of harmonics with the SPWM technique. This paper presents the dq transformation of a VSC and its design of a vectorial control to regulate the DC voltage and reactive power in a rectifier ...

Modelling and modulation of voltage source converter

2008 13th International Power Electronics and Motion Control Conference, 2008
The basic operational principle of the three-phase voltage source converter system is the subject of this paper . This type of converter is regarded as well known. Despite this, there are some details worth analysing and describing. In the drawn-out analysis the aggregated transistor state function for one branch of the converter is introduced ...

Derivation of multilevel voltage source converter topologies

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
Multilevel converters have gained popularity in both medium voltage and low voltage applications. To find out the connections between various multilevel voltage source converter topologies and reveal how to obtain new topologies, this paper has presented four methods to derive multilevel converter topologies.

Current Trends in dc: Voltage-Source Converters

IEEE Power and Energy Magazine, 2019
High-power electronics have been employed in transmission and distribution systems for many years, using thyristor-based currentsource converters. This approach has seen approximately 200 high-voltage dc (HVdc) systems and more than 1,000 static VAR compensation systems installed worldwide. The introduction of voltagesource converters (VSCs) across the
