The book consists from three parts concerning simulation of some power system, control system and power electronics case studies using matlab and powerworld simulator programs• Part A: Simulation of Some Power Electronics Case Studies in Matlab Simpowersystem Blockset:• Part B: Control of DC Motor Using Different Control Strategies in Matlab:• Part C: Investigation of the Usefulness of the PowerWorld Simulator Program Developed by “Glover, Overbye & Sarma” in the Solution of Power System Problems:I. Part A: Simulation of Some Power Electronics Case Studies in Matlab Simpowersystem Blockset:This part covers some case studies that provide detailed, realistic examples of how to use SimPowerSystems in modeling power system dynamics in various types of application that use power electronics converters. The following case studies are simulated on the paper:1- Thyristor-Based Static Var Compensator.2. Transient Stability of a Power System with SVC and PSS.3. GTO-Based STATCOM.4. Control of load flow using UPFC.5- Control of AC motor.6- Control of DC motor.7- VSC-Based HVDC Link.II. Part B: Control of DC Motor Using Different Control Strategies in Matlab:A simple model of a DC motor driving an inertial load has the angular speed of the load, , as the output and applied voltage, , as the input. The system was used as an example in [1]. The ultimate goal of this paper is to control the angular rate by varying the applied voltage using different control strategies for comparison purpose. The comparision is made between the proptional controller, integral controller, propotional and integral controller, phase lag compensator, derivitive controller, lead integral compensator, lead lag compensator, PID controller and the the linear quadratic tracker design based on the optimal control theory.III. Part C: Investigation of the Usefulness of the PowerWorld Simulator Program Developed by “Glover, Overbye & Sarma” in the Solution of Power System Problems:The objective of this part is to investigate the usefulness of the power system simulator PowerWorld program developed by “Glover, Overbye &Sarma”. The results obtained from the power simulator program were presented for different case studies. The power system network used in this study consists from 6 buses. Area 1 includes bus 1-5 while Bus 6 will be part of Area 1 in some case studies, or will form separate area 2 in other case studies for comparison purpose. Note that the Available Transfer Capability (ATC) analysis add-on which determines the maximum MW transfer possible between two parts of a power system without violating any limits, and the voltage adequacy and stability tool (VAST) add-on that can solve multiple power flow solutions in order to generate a PV curve for a particular transfer or a QV curve at a given bus, was not studied here because we don’t have yet VAST add-on and the ATC add-on packages.

The Meaning of Surah 54 Al-Qamar The Moon (La Luna) From The Holy Quran Bilingual Edition In English and Spanish Languange. The Surah revolves around the Signs of Allah SWT (God) and those who believe and deny them from amongst the polytheists. The splitting of the Qamar [moon] is amongst the great signs shown by God to the people of Makkah which they still resulted on them continuing their disbelief. The Surah talks about the approaching Day of Judgment. It describes some of the scenes of that Day. It also tells us that Allah's judgment may come here and now. There are references to the flood that came at the time of Prophet Noah AS, the punishment of the people of 'Ad, Thamud, People of Prophet Lot AS, the Pharaoh and his people. It ends with the good news for the Believers who will be near their Lord in the gardens of bliss. This Surah takes its name from the first Ayat: "The Hour has come near, and the moon has split [in two]." (54:1). Surah al-Qamar is in the 27th Juzz and the word Qamar [moon] appears in the Qur'an 27 times. An interesting observation is that the Moon orbits the Earth every 27 days. There are 55 Ayat in this Surah. La sura gira en torno a los signos de Allah SWT (Dios) y aquellos que los desmienten y niegan entre los politeístas. La división de Qamar [luna] es una de las grandes señales mostradas por Dios a la gente de La Meca, que todavía resultaron en que continuaran con su incredulidad. La sura habla del próximo Día del Juicio. Describe algunas de las escenas de ese día. También nos dice que el juicio de Allah puede venir aquí y ahora. Hay referencias al diluvio que vino en la época del profeta Noé AS, el castigo del pueblo de 'Ad, Thamud, el pueblo del profeta Lot AS, el faraón y su pueblo. Termina con las buenas nuevas para los creyentes que estarán cerca de su Señor en los jardines de la dicha. Esta Surah toma su nombre del primer Ayat: "La Hora se ha acercado, y la luna se ha partido [en dos]". (54: 1) Surah al-Qamar está en el 27 de Juzz y la palabra Qamar [luna] aparece en el Corán 27 veces. Una observación interesante es que la Luna orbita la Tierra cada 27 días. Hay 55 Ayat en esta Sura. [more]

And David's heart smote him after that he had numbered the people. And David said unto the Lord, I have sinned greatly in that I have done: and now, I beseech thee, O Lord, take away the iniquity of thy servant; for I have done very foolishly. For when David was up in the morning, the word of the Lord came unto the prophet Gad, David's seer, saying, Go and say unto David, Thus saith the Lord, I offer thee three things; choose thee one of them, that I may do it unto thee. So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thine enemies, while they pursue thee? or that there be three days' pestilence in thy land? now advise, and see what answer I shall return to him that sent me. And David said unto Gad, I am in a great strait: let us fall now into the hand of the Lord; for his mercies are great: and let me not fall into the hand of man. So the Lord sent a pestilence upon Israel from the morning even to the time appointed: and there died of the people from Dan even to Beersheba seventy thousand men. And when the angel stretched out his hand upon Jerusalem to destroy it, the Lord repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the Lord was by the threshingplace of Araunah the Jebusite. And David spake unto the Lord when he saw the angel that smote the people, and said, Lo, I have sinned, and I have done wickedly: but these sheep, what have they done? let thine hand, I pray thee, be against me, and against my father's house. And Gad came that day to David, and said unto him, Go up, rear an altar unto the Lord in the threshingfloor of Araunah the Jebusite. And David, according to the saying of Gad, went up as the Lord commanded. And Araunah looked, and saw the king and his servants coming on toward him: and Araunah went out, and bowed himself before the king on his face upon the ground. And Araunah said, Wherefore is my lord the king come to his servant? And David said, To buy the threshingfloor of thee, to build an altar unto the Lord, that the plague may be stayed from the people.

King Solomon said this. I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit. Ecclesiastes 1 King James Version (KJV) 1 The words of the Preacher, the son of David, king in Jerusalem. 2 Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity. 3 What profit hath a man of all his labour which he taketh under the sun? 4 One generation passeth away, and another generation cometh: but the earth abideth for ever. 5 The sun also ariseth, and the sun goeth down, and hasteth to his place where he arose. 6 The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits. 7 All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again. 8 All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing. 9 The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun. 10 Is there any thing whereof it may be said, See, this is new? it hath been already of old time, which was before us. 11 There is no remembrance of former things; neither shall there be any remembrance of things that are to come with those that shall come after. 12 I the Preacher was king over Israel in Jerusalem.

Romantic love poem. The One Who Feeds My Soul. In the depths of my mind, I come to find. That there is one who feeds my soul. Whether far or near, she is always here, And she's the one who makes me whole. In a thousand dreams, it always seems. That her beauty speeds my way Past valleys and peeks as my spirit seeks. To create in each new day. With this passion and drive, I live, I thrive! And all because she is there. For her touch and her love, I rise above, Seek to better myself in her care. She is ever my queen, she is kind and serene, And a vision of heavenly ways. For eternity's years, through both laughter and tears. I am hers to the end of days. [more]

When Sailors Have Discovered Rocks Or Breakers, And Have Had The Good Luck To Escape With Life From Amidst Them, They, Unless They Be Pirates Or Barbarians As Well As Sailors, Point Out The Spots For The Placing Of Buoys And Of Lights, In Order That Others May Not Be Exposed To The Danger Which They Have So Narrowly Escaped. What Man Of Common Humanity, Having, By Good Luck, Missed Being Engulfed In a Quagmire Or Quicksand, Will Withhold From His Neighbours A Knowledge Of The Peril Without Which The Dangerous Spots Are Not To Be Approached? 2. The Great Effect Which Correct Opinions And Sound Principles, Imbibed In Early Life, Together With The Good Conduct, At That Age, Which Must Naturally Result From Such Opinions And Principles; The Great Effect Which These Have On The Whole Course Of Our Lives Is, And Must Be, Well Known To Every Man Of Common Observation.
