Power System Note 1 4 Power System Analysis Studocu The components or various sections of power system may operate at different voltage and power levels. it will be convenient for analysis of power system if the voltage, power, current and impedance rating of components of power system are expressed with reference to a common value called base value. advantages of per unit system i. Introduction to power system analysis, single line diagrams, impedance diagrams, reactance diagrams, and per unit system calculations. •with per unit quantities, all voltage magnitudes would be close to 1.0 for normal operation. •going from per unit quantities to actual quantities, or vice versa, is just a rescaling operation. •to obtain actual voltages from per unit values, multiply the per unit values with the “base voltage” of each node. 27the per unit system per unit system the per unit system has a major advantage in power system analysis, it simplifies the solution of a circuit containing transformers. easy to analyze real power that contains a mixture of y – delta connections, and also containing very, very many transformers.

The reason the per unit system is employed is because it simplifies calculation of voltages, currents, and impedances o f a power system network. imagine a 3 phase system with a generator, a transformer, a t line, another transformer, and a load. This document provides sample problems related to power system analysis including per unit calculations, modeling of system components, single line and reactance diagrams, bus admittance and impedance matrices. specifically, it includes: 1. In order to calculate the performance of a power system under load condition or upon the occurrence of a fault, the one line diagram is used to draw the single phase or per phase equivalent circuit of the system. refer the one line diagram of a sample power system shown in fig. 1.4. Fundamental to any power system analysis is the know how of per unit systems. this metric is widely used to describe voltages, currents, and impedances in a power system.
