In the wind farms, fans are widely distribution with large amount and they are away from the monitoring center, working environment is poor. In order to ensure the safe and stable operation of the wind farms, the wind power operation requirements need to be satisfied, own better function performance and stability of remote monitoring system to improve the management efficiency. In view of this,...

This paper surveys recent results in game theory and cooperative control and highlights their implications for the problem of optimizing energy production in wind farms. One such result is a simple payoff-based learning rule that is completely decentralized and leads to an efficient configuration of actions in virtually any distributed system. We demonstrate that this learning rule can be used ...

Large offshore wind farms are recently emerging as promising alternative power sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC t...

INTRODUCTION Recently, amplitude modulation, low frequency and infrasound noise from wind farms has been the subject of complaints, many different media reports and a Senate Inquiry in Australia. The Ministry of Environment of Ontario province in Canada, amongst many other regulators, has been considering a new policy on low-frequency infrasound noise from wind farms and commissioned a literatu...

High-voltage direct current (HVDC) lines with line-commutated converter (LCC) are being increasingly employed to transmit bulk wind power over long distance. However, this may cause the sub-synchronous torsional interaction (SSTI) between the wind farms and the LCC-HVDC system. The SSTI characteristics of wind farms with fixed-speed induction generator (FSIG) wind turbines connected to LCC-HVDC...

. The main purpose of the standard IEC 61400-25 is the unification of communication systems in wind power plants, both for internal exchange of information and for remote control. Most of the current control and monitoring systems used in wind farms are vendor-specific and the protocols and data provided by these systems are therefore dependent on their manufacturer. This paper explains the mai...

Wind farm capacities and transmission distances will be increased significantly in the UK, Round 3 offshore wind farms. This will be a serious challenge when HVDC transmission technologies are considered. The purpose of high temperature superconductor (HTS) cables as the transmission conductor in HVDC transmission system is mainly to reduce the joule losses (IR) arising from the power transmiss...

Taiwan is located on the Pacific seismic belt, and the soil conditions of Taiwan’s offshore wind farms are softer than those in Europe. To ensure safety and stability of the offshore wind turbine supporting structures, it is important to assess the offshore wind farms seismic forces reasonably. In this paper, the relevant seismic and geological data are obtained for Chang-Bin offshore wind farm...

Wind energy has huge potential to become major source of renewable energy for the modern world. For integrating wind farms to the AC grid, HVDC transmission systems have several advantages over AC transmission systems. This paper presents the design and control of voltage source converter based HVDC system for integration of wind farms in to AC grid. The designed VSC-HVDC system performance und...

Recent advancements in the wind turbine technology, combined with available federal and state incentives, have greatly enhanced the development of wind powered electric generation facilities in the Eastern United States. Particularly ridges of the Allegany Mountains in New York, Pennsylvania, Maryland, West Virginia, and Virginia have become attractive sites for commercial wind farm developers....
