Allen Report
This document summarizes a wind power project in Rameswaram, India that analyzed the feasibility of installing two Gamesa G58 wind turbine generators (WTGs) with a rated capacity of 850 kW each. WindPro software was used to model the site's wind resource, estimate annual energy output of 2,131 MWh per WTG, and calculate a capacity factor of 28.6%. Economic analysis estimated a payback period of 7.3 years based on the local electricity rate. Noise and shadow modeling found the WTGs would meet regulatory limits. The project was deemed economically feasible if other installation costs beyond the turbine costs were reduced or excluded.
LOW VOLTAGE RIDE - THROUGH CAPABILITY OF WIND FARMS
Nowadays wind turbines are generally required to offer ancillary services similar to those
provided by conventional generators. One of the most important services wind turbines must offer is
to stay connected to the grid in fault situations delivering the reactive current specified in the recent
grid codes. In this paper, FACTS solutions for fixed speed wind farms such as DVR (Dynamic
Voltage Restorer) are presented as well as classic control and crowbar solutions for variable speed
wind turbines.
Overview lvrt capability of dfig techniques
This document summarizes techniques for providing low voltage ride through (LVRT) capability for doubly fed induction generator (DFIG) wind turbine systems. It discusses three main techniques:
1) Active crowbar protection disconnects the rotor side converter during faults to protect it, turning the generator into a squirrel cage induction machine. This allows the DFIG to stay connected but draws a large reactive power.
2) Flexible AC transmission systems (FACTS) devices like STATCOM and dynamic voltage restorer (DVR) can provide external protection by injecting compensating voltages. Using a DVR avoids the need for internal DFIG protection methods.
3) Stator current feedback is investigated as another technique for

The document summarizes research on Low Voltage Ride Through (LVRT) capability for wind power systems. It discusses LVRT requirements specified in grid codes that require wind turbines to remain connected during faults and provide reactive power support. It then reviews different wind turbine generator topologies and their responses to faults. Several control strategies and technologies to enable LVRT capability are presented, including chopper resistors, energy storage, and derated generator operation. Simulation results validating one control scheme are shown through various graphs. The conclusion states that combining multiple technologies can help implement LVRT and connect wind power systems to the grid more effectively.
Wind power
Wind turbines convert the kinetic energy of wind into electrical energy. They consist of blades, a rotor, a nacelle housing a generator and gearbox, and a tower. As wind passes the blades, they spin the rotor which turns the shaft and gearbox to increase rotational speed and power the generator to produce electricity. Egypt has over 500MW of installed wind power capacity concentrated in farms along the Red Sea coast. The advantages of wind power are that it is renewable and produces no emissions, while the disadvantages include intermittent availability and potential negative impacts on landscapes and communities. Problems faced by wind power include noise, transmission issues due to intermittent wind, social impacts, and fire risks from overheated or failed components inside nacelles.
Wind Energy Technology
This document provides an overview of a presentation on wind energy technology. It discusses:
1. The status and development of wind energy in India, including installed capacity and leading states.
2. The key components and aerodynamics of wind turbines, including blades, generators, foundations and towers.
3. The different types of wind electric generators and their operating principles.
4. The control and safety systems used in wind turbines and their important functions.
5. The integration of wind power into electrical grids and technical regulations for connecting wind farms to the grid.
Improved reactive power capability with grid connected doubly fed induction g...
In the past, most national grid codes and standards did not require wind turbines to support the power system during a disturbance. For example during a grid fault or sudden drop in frequency wind turbines were tripped off the system. However, as the wind power penetration continues to increase, the interaction between the wind turbines and the power system has become more important. This is because, when all wind turbines would be disconnected in case of a grid failure, these renewable generators will, unlike conventional power plants, not be able to support the voltage and the frequency of the grid during and immediately following the grid failure. This would cause major problems for the systems stability.
Therefore, wind farms will have to continue to operate during system disturbances and support the network voltage and frequency. Network design codes are now being revised to reflect this new requirement. A special focus in this requirement is drawn to both the fault ride-through capability and the grid support capability. Fault ride-through capability addresses mainly the design of the wind turbine controller in such a way that the wind turbine is able to remain connected to the network during grid faults (e.g. short circuit faults). While grid support capability represents the wind turbine capability to assist the power system by supplying ancillary services, i.e. such as supplying reactive power, in order to help the grid voltage recovery during and just after the clearance of grid faults. Due to the partial-scale power converter, wind turbines based on the DFIG are very sensitive to grid disturbances, especially to voltage dips during grid faults.
Faults in the power system, even far away from the location of the turbine, can cause a voltage dip at the connection point of the wind turbine. The abrupt drop of the grid voltage will cause over-current in the rotor windings and over- voltage in the DC bus of the power converters. Without any protection, this will certainly lead to the destruction of the converters. In addition, it will also cause over-speeding of the wind turbine, which will threaten the safe operation of the turbine. Thus a lot of research works have been carried out on the LVRT ability of DFIG wind turbines under the grid fault. These LVRT strategies can be divided into two main types: the active method by improving control strategies, the passive scheme with additional hardware protective devices.
Power Electronic Converter
This document provides an overview of wind turbine systems that use power electronics converters. It discusses how wind energy is converted into electrical energy and fed into the electrical grid. Power electronics converters are necessary to regulate voltage and frequency from the generator to meet grid requirements. Common converter configurations for wind turbines include the doubly fed induction generator with a partial scale back-to-back converter and permanent magnet synchronous generators with a full-scale back-to-back converter. Power electronics improve system stability and power quality by enabling control of active and reactive power flow between the generator and grid.

Wind Turbine Generators
The document discusses different types of wind turbine generators used in wind energy technology. It covers the fundamentals of wind power generation and describes various generator and motor types used - including induction motors, permanent magnet synchronous generators, squirrel cage induction generators, wound rotor induction generators, and doubly fed induction generators. The document also discusses high temperature superconducting wind turbine generators and provides comparisons of advantages and disadvantages of different generator types.
Power electronics in Wind Turbine Systems
Wind turbines use power electronics like doubly fed induction generators (DFIGs) consisting of wound rotors, induction generators, and AC/DC/AC converters. DFIGs allow variable speed operation, reduce converter size/cost, and enable reactive power control. They work by converting the turbine's mechanical energy to electrical energy. The stator is directly connected to the grid while the rotor is fed at variable frequency by the converter. The converter controls the rotor speed and active/reactive power flow. DFIGs offer advantages like low losses, compact design, and speed regulation from ±20-25% but have disadvantages like slip ring maintenance and complex control.

CCCS successfully moved many Career and Technical Education (CTE) courses to blended/hybrid formats. Originally only 15 of 122 relevant courses were hybrid, but a deadline of December 2013 required all 122 be hybrid. CCCS developed a plan with the following steps:
1) Analyze certificates and courses, identifying high-enrollment and certifiable courses for hybrid conversion.
2) Create a course development plan with benchmarks and incentives for colleges to share hybrid courses.
3) Work with faculty through onsite instructional designers to "chunk" content into online and hands-on activities, and assess quality.
4) Publish hybrid courses openly online to increase enrollment in certificate programs and meet industry demands within

FRCC MAT050 Intro
This document provides information about a quantitative literacy course called MAT 050. It is a hybrid course designed for students planning to take other math courses. Students will spend about 12 hours per week on course material, including 2-3.5 hours in class and the remaining hours outside of class. The course uses an online learning platform called D2L and online homework system called My Math Lab. Students will have access to course resources like power point presentations, online tutoring, and help centers. Assessment includes group activities, homework, quizzes, tests, and a final exam. Students are expected to complete practice problems, activities, and homework each week.
FRCC MAT050 Unit 2 Changes
The document outlines several changes and updates to instructional methods. Scaffolding is described as a learning process that provides support tailored to student needs to help them achieve learning goals, with supports gradually removed as students develop independent strategies. Note-taking no longer requires template collection. Videos replace textbooks and will not have associated problems collected. Group work will still be collected but allows selecting two assignments weekly. Homework can also select two assignments weekly but does not require complete sentences. Online homework will now be graded directly rather than collecting printouts.
FRCC MAT050 Unit 3 Changes
Unit 3 focuses on getting students ready for transfer level courses through flipped teaching with math videos students must watch before class. The instructor will check that students watched videos and took notes in each class, no longer providing note templates. Group work will now be graded in class with students earning points for participating, and cannot be made up if absent. Homework from the textbook and online platform will no longer be collected, though similar questions may appear on exams.
FRCC MAT050 Factoring (Sect 3.11)
This document provides instructions and examples for factoring trinomials and binomials. It begins with an introduction to factoring trinomials of the form ax^2 + bx + c. It then gives examples of factoring different types of expressions, including factoring out negatives, dealing with two variables, and factoring completely. It concludes with a list of homework problems from the textbook for further practice factoring expressions.
FRCC MAT050 Dividing by a Monomial (Sect 3.10)
This document discusses dividing polynomials by monomials. It provides examples of dividing terms with variables by monomials, including factoring out negatives. The homework assignments are to complete odd problems from pages 297 and 303 of the textbook, with no additional problems from an online system.
FRCC MAT050 Linear Inequalities (Sect 3.9)
This document discusses linear inequalities and their properties. A linear inequality is any relationship of the form ax + b, where a is not equal to 0. The key points covered include:
- Linear inequalities can use the symbols <, >, ≤, or ≥ to represent relationships.
- When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality symbol flips.
- Graphing linear inequalities results in solutions represented by regions on a number line.
- Compound inequalities involving AND or OR statements can be solved by evaluating each inequality separately and combining the solutions appropriately.
FRCC MAT050 Solving Formulas (Sect 3.8)
This document outlines the steps to solve formulas in Section 3.8, including group work to explore problems on page 272 numbers 1-8, a class discussion of how it works using problems on page 274 numbers 9-11, and homework assignments of problems on page 279 numbers 1-12 and the My Math Lab Section 3.8.
FRCC MAT050 Equations of Lines (Sect 3.7)
This document provides instructions for group work and homework on equations of lines. Students are asked to explore examples of writing equations of lines and describe how it connects to group work. For homework, students should complete selected problems from the textbook on how to write equations of lines without using the online system My Math Lab.
