Tv Triangle Case Study
V. CASE STUDY FOR A TWO-STAGE CONVERSION For two stage grid connection the PV array consists of 5 series and 11 parallel string. After that the boost converter used which are controlled to extract maximum power and at the same time to control the dc link voltage at 600 volts. Inductance of 10mh and capacitance of 2500 µF are used in the boost converter. The three phase VSI has the current control loop and the inverter is modeled to supply 20amps line current. The IGBT model used is STGW30NC120HD. Fig.4.Two stage control diagram A. Control Strategies • MPPT: - In this article perturb and observe MPPT algorithm is used for simplicity.If there is an increment in the power, the perturbation should be kept in the same direction and if the power …show more content…
The input to the PLL is the three-phase grid voltage, which will be converted in to synchronously rotating reference frame and the PLL gets locked by setting V*d to be zero. Where V*d is the direct-axis reference voltage. The loop filter PI is a low pass filter and is used to provide the controlled signal to the Voltage Controlled Oscillator (VCO) which acts as an integrator. The output of the PI- controller is the grid frequency, which will be integrated by the VCO to obtain the phase angle of the converter. Whenever the difference of phase angles between the inverter and the grid reduced to zero, PLL becomes active which results in synchronously rotating voltage vectors with Vd as zero and Vq will be of the magnitude of grid voltage. The next question is about the active and reactive components of grid current. Simply active component of grid current means the component which defines the active power and reactive component of grid current means the component which defines the reactive power .Sine the reference vector rotating in the dq-reference frame has aligned with quadrature-axis means, Vd will be zero and Vq will be of the magnitude of grid voltage. In this case the in phase component that is quadrature-axis current will be the active current and direct-axis current will be the reactive current component as shown in Figure
Texas Iron Triangle
931 Words | 4 PagesAdvancement in politics requires many factors, but the most significant component to achieve success in politics is to maintain good relationships with other institutions – both unofficial and official institutions. Together, the bureaucracy, interest groups, and committees of the Congress form the iron triangle, which refers to the concept that the bureaucrats, the interest groups and the congressional committees must work together in order to spread their influence throughout the nation – or the state – and to develop their powers. Iron triangles also exist in Texas, and one of Texas’ iron triangles focuses on higher education. One of the interest groups of Texas’ higher education iron triangle is the Texas Coalition for Excellence in Higher
Gil's Sportsplex Analysis
550 Words | 3 PagesIn his essay “Gil’s Sportsplex”, Gil Fried states that Gil Giles is always obsessed with softball and thus, he tends to invest a sportsplex after he retired (1). Fried introduces Gil’s backgrounds that he is a former police officer without any experiences in running a sports facility (2). Elsewhere, Fried demonstrates various industry analyses about sportaplex, for example, the definition of sportsplex is a facility offering multiple indoor and outdoor sports (2), and the “Sportsplex Operators and Developers Association (SODA)” propose some guidelines for implementing a sportsplex, such as “developing a needs assessment, feasibility study and preliminary design”(2). In addition, Fried cites CT sportsplex information, which includes the location, population, the charging fees, sponsorship packages, and the competing component research, as a frame example for Gil’s sportsplex (3-4).
The Role Of Television In The 1960's
659 Words | 3 PagesTelevision in the 1960’s The television was and still is an important invention to society.

Comparison Of WCBS 880 And 1010 WINS
955 Words | 4 PagesWCBS 880 and 1010 WINS are both radio stations owned by CBS radio. These radio stations are in a competition to gain more audiences. Both stations main purpose is to target a specific audience, and its primary product is to sell listeners to advertisers. After comparing both radio stations one found that WCBS 880 delivers the news in a direct way while 1010 WINS delivers the news in a dramatic way. WCBS 880 and 1010 WINS are on AM dials and have a news format.
WIAT III Case Study
846 Words | 4 PagesThe WIAT-III has several limitations to include the time it takes to administer, the measure is only available in English, the test is highly verbal, some of the scoring criteria for the writing sections did not provide an adequate explanation, and although the sample was normalized on over 2,000 students, it was still normalized on a very small number of people (Vaughan-Jensen, Adame, McLean, & Gamez, 2011). Administering the assessment can take over two hours for a person who is well training in administering the assessment. The WIAT-III is widely used therefore only having the measure in English is a limitation, everyone that is administer the assessment may not have English as their native language, resulting in misinterpretation of the
Six Degrees Of Separation: Film Analysis

Television In The 1950's
432 Words | 2 PagesTelevision wasn’t a product that was owned by the public until the 1950s, the essential technology was created earlier in the century. John Logie Baird started constructing a functional television shortly after the World War I in the South Coast of England. In 1924, he finally made progress when he transmitted a flickering image across the space of several feet, then in 1925, he created the first real television picture in grayscale, with the use of a ventriloquist 's dummy and then a human face. The TV was brought into the eyes of many people in 1926, when John Logie Baird presented the device in presence of 50 scientists. John’s main goal was to provide a new source of entertainment which can help bring families together.
Tip Top Lodge Analysis
245 Words | 1 PagesO’Brien describes his experience at the Tip Top Lodge as one that resolved an immense inner conflict he faced. When O’Brien received his draft card in the mail to fight in Vietnam, he immediately had to face the fact that he had been “drafted to fight a war that [he] hated” (O’Brien 38). In the face of danger and what he deemed as “moral confusion,” O’Brien suddenly decided that fleeing to Canada was the only way to avoid fighting in Vietnam. While driving north, O’Brien stopped at a fishing resort called the Tip Top Lodge and met Elroy Berdahl. While he refrained from asking obvious questions during O’Brien’s six-day-stay, Berdahl presumably understood O’Brien’s situation.
How Entertainment Conquered Reality Analysis
1448 Words | 6 PagesNeal Gabler defines entertainment in his book Life the Movie: How Entertainment Conquered Reality as a damaging power which is able to “ruin” society (Gabler, 1998). However, according to Longman Dictionary, entertainment refers to “things such as films, television, performances etc that are intended to amuse or interest people”; to be more objective, it “entails communication via external stimuli, which reaches a generally passive audience and gives some portion of that audience pleasure” (Bates & Ferri, 2010). The contradiction of these definitions shows that entertainment makes both negative and positive influences on society, so it is not entertainment itself, but the way how it is used by human beings has the capacity to “ruin” or improve
