PDF-Module Power System Structures Lecture A vertically integrated utility Objectives

In this type of structure one utility handles the all functions of generation transmission and distribution within a certain geographical area The operation and coordination of such a system is somewhat simple since all functions are controllable by. e LSI Linear shift invariant systems We shall define the term Impulse response in context to LSI systems We shall learn Convolution an operation which helps us find the output of the LTI system given the impulse response and the input signal NOTE I Unit impulse function Unit step function Their relation in both continuous and discrete domain We shall even look at the Sifting property of the unit impulse function Basic Signals in detail We now introduce formally some of the basic signals namely Balanced and unbalanced transmission line Transit time effect on a transmission line at high frequencies Dominance of the reactive component over resistive component Concept of distributed elements and conditions under which the lumped element circu Generator Excitation Systems and reactive power characteristics of power system components Since voltage magnitudes in a system are intimately related to the ability of various components to absorb or supply reactive power we shall begin by reviewin 1 Motivation Why is power dissipation so important Power dissipation considerations have become important not only from reliability point of view but they have assumed greater importance by the advent of portable battery driven devices like laptops c In an equilibrium situation there cannot be an electric field inside a conductor as this would cause charges electrons or ions to move around Charge density inside a conductor is zero This follows from Gausss law As the charge density This does no The velocity of different frequencies can be different due to intrinsic properties of the medium or due to dispersive nature of the bound structure like the optical fiber Due to dispersion when the optical pulses travel along the fiber they broaden Memory Memory is a property relev ant o nly to systems whose input and output signals have the same independent variable A system is said to be memoryless if its output for each value of the independent variable is dependent only on the input signa 46 Bending Deflection due to Temperature Variation Consider a beam member refer Figure 429 subjected to temperature gradient over the depth of beam such that 422 where temperature at the top of the beam and temperature at the bottom of the beam Th Calculate the magnetic field for certain current configuration using Amperes law Derive the differential form of Amperes law Amperes Law BiotSavarts law for magnetic field due to a current element is difficult to visualize physically as such element What is a vertically integrated utility? What are the conditions that have led to changes in the traditional power system structure ?
