Coordinated Utilisation Of Wind Farm Reactive Power Capability For System Loss Optimisation, Lasantha Meegahapola, S Durairaj, D Flynn, B Fox
Coordinated Utilisation Of Wind Farm Reactive Power Capability For System Loss Optimisation, Lasantha Meegahapola, S Durairaj, D Flynn, B Fox
Dr Lasantha G Meegahapola
Most wind farms currently being installed are based upon doubly fed induction generator (DFIG) or direct-drive synchronous generator (DDSG) technology. Given that one of the impacts of introducing distributed generation is an alteration of steady-state power flows and voltages, both technologies are capable of providing local voltage support. Wind farms may, therefore, be included in optimal power flow (OPF) calculations to minimise fuel cost and/or network losses. The IEEE 30-bus system is considered as a case study, comparing fixed-speed induction generator (FSIG) requirements with DFIG capability. Results are presented for a range of DFIG capability modes, at varying system load …
Voltage And Power Quality Improvement Strategy For A Dfig Wind Farm During Variable Wind Conditions, L Meegahapola, T Littler, B Fox, J Kennedy, D Flynn
Voltage And Power Quality Improvement Strategy For A Dfig Wind Farm During Variable Wind Conditions, L Meegahapola, T Littler, B Fox, J Kennedy, D Flynn
Dr Lasantha G Meegahapola
This paper presents a voltage and power quality enhancement scheme for a doubly-fed induction generator (DFIG) wind farm during variable wind conditions. The wind profiles were derived considering the measured data at a DFIG wind farm located in Northern Ireland (NI). The aggregated DFIG wind farm model was validated using measured data at a wind farm during variable generation. The voltage control strategy was developed considering the X/R ratio of the wind farm feeder which connects the wind farm and the grid. The performance of the proposed strategy was evaluated for different X/R ratios, and wind profiles with different characteristics. …

Bovine tuberculosis (bTB) is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in MI, USA. Currently, the rates of farm visitation by deer and co-use of forage resources by cattle and deer are poorly understood. To evaluate the extent deer and livestock may share forage resources, we investigated farm, yard, and cattle-use area visitation by white-tailed deer and compared visitation with common livestock management practices. We fitted 25 female white-tailed deer near the bTB-infected zone in Michigan’s Lower Peninsula with global positioning system collars. Livestock management practices associated with farm visitation included presence of confined feeding pastures, number of …

Nebraska Farm Real Estate Reports
This report represents the 35th annual edition of the Nebraska Farm Real Estate Market Developments series. It has continued to provide an important informational role regarding agricultural land market dynamics for the many stakeholders. As stated in the introduction of the first annual report: “The dynamics of the farm real estate market, particularly in recent years, suggests that accurate and complete information concerning this market is of great importance. From the standpoint of the public interest as well as that of individual participants, all land market decisions should be based upon a sound understanding of the current market situation.” 1 …

A Guide To The Pomona College Organic Farm: An Introduction To The Farm’S History And Basic Gardening Skills And Techniques, Adam J. Long
Pomona Senior Theses
It was almost four years ago when I first visited the Pomona College Organic Farm and since then I have learned everything from the basics of gardening to the complex steps required to organize students for events and activities. As I learned more and saw so many students come and go, I saw a need for written documentation that would allow future generations of students to benefit from the skills that my peers and I have learned in our time at the Farm. The value of the Farm is grounded in having a vibrant physical space, and right now the …

Historic Preservation
The primary wood columns and secondary wall studs show a variety of conditions. Most notably, the columns at the foundation level have been cut to remove rotted portions and are now supported by concrete footings. The columns on the first floor level have been reinforced with additional pieces of wood. An additive process of building up the structure is evident, although it is not clear if this is historically original or the results of the repair efforts circa 2005.
