    Characteristics of DC Series Generator: Experiment # 16

    Uploaded by

    Ahmad Raza
    The document describes building a Simulink model of a DC series generator. It includes the following steps: 1. Search and drag relevant components like the DC machine, constant load, voltage measurement, scope, and ground blocks into the model. 2. Select parameters for the DC machine like speed and connect all components in the proper configuration. 3. Run the simulation. The output shows voltage in the negative due to there being no pre-existing magnetic flux in the ideal MATLAB model, unlike a real generator.

    EXPERIMENT # 16

    Characteristics of DC Series Generator


    1.0 Objectives

    The objective of this lab is to introduce students to the Simulink environment and
    enable them to perform basic operations related to Simulink.

    2.0 Learning Outcomes

    i. Observe the Output and Input of Dc Series Generator with Matlab Simulink
    Environment.

    3.0 Software

     MATLAB Simulink

    4.0 Introduction

    There are generally three most important characteristics of series wound DC generator
    which show the relation between various quantities such as series field current or
    excitation current, generated voltage, terminal voltage and load current.
    5.0 Starting up Simulink

    In order to use Simulink, you must first start MATLAB. With MATLAB running,
    there are two ways to start Simulink:
    1-Click on New (+ icon) then from the drop down menu click on Simulink Model
    as shown in the picture.
    2-Type ‘simulink’ at the MATLAB prompt followed by a carriage return (press the Enter
    key)

    Fig 2: Method 2 to open Simulink.


    Fig 3: Simulink Library Browser.

    Next, select New Model from the File pull-down menu in the Library Browser.
    The following blank window appears on your screen. We will refer to this window
    as the model window.

    Task-1
    Building a Simulink Model for DC Series Generator

    Building a Simulink model of a system consists of selecting the appropriate blocks and
    connecting them in a way that represents the mathematical models. Since the best way
    to learn a simulation tool is to work with it, this first tutorial will guide you through a
    simple example. We will build the block diagram for a simple model consisting of a
    sinusoidal input multiplied by a constant gain, which is depicted below.

    6.0 Procedure
    Following are the steps to draw the desire model on the DC Series Motor

    1. In search bar, type the desired component and drag it into the model as shown
    in
    figure below:
    One bye One Search All Components and select it,

    i. DC Machine
    ii. Constant Load

    iii. Select DC Voltage Measurment


    iv. Select The Scope To Observe The Output Waves of DC Series Generator
    Parameters

    v. Select The Ground


    vi. Select the Voltage Measurement for Observe Output

    vii. Select the Powergull


    viii. Select DEMUX

    ix. Select The Display to Check the Output Voltage

    x. Select The RLC Branch Load


    1. Use method and draw the DC Series Machine model by using simulink tools .

    2. Now Select Parameter of DC Machine

    3. Now “Run” the simulation, clicking on the icon as shown into the figure below:
    Circuit With Output Values

     Speed
    1750 rpm
     Armature Voltage
    -3.88 e-0.7
     Armature Current & Field Current
    3.88 e-08

     Observation and Conclusion ( Why Voltage Is Not Generated )

    The starting voltage in a DC series generator is generated by the residual


    magnetism, which is actually saved in the series winding. But there is an ideal case
    in the mat lab because of which there is no pre-existing magnetic flux in the field
    due to which the field winding does not get voltage to be Excitation. That is why
    we are getting the value of voltage in negative .
