Transcript of Numerical Methods: Numerical Analysis of A Power Flow Problem

Mohammed Mushtaha Abdullah Zia Khalid Abdullatif Numerical Analysis of A Power Flow Problem 1. Introduction A. Single Line Diagram Single Line Diagrams are used to describe power networks. B. Voltage Representation C. Real and Reactive Power E. Power Flow 2. Problem Solving Methodology Problem Solving Methodology 4. Problem Solving Methodology Introduction and Background Single Line Diagram Voltage as a vector quantity Real and Reactive Power Per Unit System Power Flow Problem Solving Methodology Problem Statement and Solution Simulation using Power-World Simulator Developing MATLAB Code Conclusion Content Electrical Power Generation The magnitude of the AC voltage is defined as the voltage equivalent to the DC voltage that can produce the same power dissipation in a load. In AC circuits, the magnitude of the voltage is the RMS result of the oscillating voltage power is the rate of consuming or producing energy The real power is the actual amount of electrical energy consumed by a circuit or generated by a source. Reactive power is energy that gets stored inside the circuit and don’t get consumed. D. Per Unit System The per-unit is used primarily in power flow studies to help in simplifying complicated power systems. The term “Power Flow”, also called “Load Flow”, referrers to the study of how the steady state electric power is distributed all over the electric loads. Slack bus: This is an open bus that has a generator connected to it. PV bus: This is a bus with generator connected to it. PQ bus: This is a bus that has no generator. 3. Problem Statement and Solution 3. Problem Statement and Solution 3. Problem Statement and Solution 4. Simulation using Power-World Simulator 5. Developing MATLAB Code Conclusion The use of numerical analysis in not only limited to power systems in electrical engineering. Other aspects of electrical engineering including analogue filter design, Very Large Scale Integration (VLSI) chip designing, and analogue electronics. This project shows that numerical analysis is an incredibly strong and versatile tool that helps engineers in solving and designing technical processes. Thank you
