| | A Survey of Fast Power Reduction Methods for VSC Conntected Wind Power Plants Consisting of Different Turbine Types - Paper
By Arjen A. van der Meer, Ralph L. Hendriks, Wil L. Kling | |
|
Abstract: In this paper, a survey of fast active power reduction methods is given for improving fault-ride-through capabilities for wind parks that are connected to the grid through a voltage sourced converter (VSC) HVDC transmission scheme. In case of faults in the main grid, the limited current rating of the converter causes the direct voltage to rise quickly and hence fast reduction of generated power is required to keep the scheme in operation. This contribution studies the working principles of the power reduction methods on different turbine types and four particular cases with mixed turbine types have been studied. It turned out that frequency increase and voltage reduction is the most promising and cost effective option. Furthermore it is shown that a combination of the proposed reduction methods leads to robust fault ride-through operation of the VSC-HVDC connected wind park.

| | Load-Frequency Control of Synchronous Areas Using a Wind Farm Connected via HVDC-VSC - Paper
By S. Jensen, F.W. Fuchs | |
|
Abstract: The power system control in terms of primary control of a HVDC-VSC fed wind farm grid is designed and analyzed. Due to decoupling effects of the DC-link, classical approaches are not sufficient for participating of a wind farm at load-frequency control of synchronous areas. This paper presents a theoretical analysis and investigation results of primary reserve allocation and retrieval with three different methods to cope this problem.

| | Design Considerations for a Power Electronic Converter for Series Connection of Wind Turbines - Paper
By Stefan Lundberg, Torbjörn Thiringer | |
|
Abstract: When connecting the wind turbines in series the output voltage will not be constant as in a shunt connection. The common quantity for the turbines will be the current and the output voltage will vary depending on the power production. For the DC/DC converter transformer a toroid shape is proposed and an approximate expression for the electric field inside the transformer were derived and compared with FEM calculations.
