    introduction to scada for pv
  • 00:00:28
    systems we will start off by listing the
  • 00:00:31
    misconception about scada
  • 00:00:35
    it's not something that was built
  • 00:00:38
    based on magic
  • 00:00:41
    nor voodoo
  • 00:00:43
    nor a single piece of equipment
  • 00:00:46
    block box
  • 00:00:47
    a computer
  • 00:00:51
    or something like internet or
  • 00:00:53
    telecommunications
  • 00:00:56
    so what is scada then
  • 00:00:58
    scada is an acronym that stands for
  • 00:01:01
    supervisory control and data acquisition
  • 00:01:06
    it is a system
  • 00:01:10
    which is integrated an integrated set of
  • 00:01:12
    software hardware
  • 00:01:14
    network and control subsystems that work
  • 00:01:18
    together to provide real-time visibility
  • 00:01:20
    in control of a facility
  • 00:01:23
    like in this tutorial a pv or a
  • 00:01:27
    photovoltaic power plant
  • 00:01:31
    in other words
  • 00:01:32
    it's just a centralized system that
  • 00:01:34
    monitors and controls the entire plant
  • 00:01:43
    when we talk about scada we can
  • 00:01:46
    associate
  • 00:01:47
    its functionality to the human nervous
  • 00:01:50
    system
  • 00:01:51
    wherein
  • 00:01:52
    it is a network of neurons whose main
  • 00:01:55
    feature is to generate
  • 00:01:58
    modulate and transmit information
  • 00:02:02
    between all the different parts of the
  • 00:02:05
    human body
  • 00:02:08
    you have your fiber optic and ethernet
  • 00:02:11
    networks
  • 00:02:14
    that acts like nerves
  • 00:02:16
    and your sensors
  • 00:02:19
    are value
  • 00:02:20
    generators like mirrors and
  • 00:02:22
    weatherizations
  • 00:02:24
    acts as eyes
  • 00:02:26
    ears or skin
  • 00:02:29
    and your grid controllers
  • 00:02:32
    serves as the autonomic side of the
  • 00:02:35
    nervous system
  • 00:02:38
    then your operators
  • 00:02:40
    or end users of the data set
  • 00:02:43
    would be
  • 00:02:44
    your brain
  • 00:02:46
    and can then respond accordingly
  • 00:02:51
    let's illustrate the scada elements for
  • 00:02:54
    a photovoltaic flower plant
  • 00:02:59
    in this basic diagram for a pv plant
  • 00:03:04
    attributes such as
  • 00:03:06
    kilowatts
  • 00:03:08
    voltage
  • 00:03:10
    operating status
  • 00:03:12
    and alarms
  • 00:03:15
    are being pulled from the inputs
  • 00:03:18
    like what you have on the left
  • 00:03:21
    your inverse
  • 00:03:23
    and those data sets are being
  • 00:03:26
    transmitted to
  • 00:03:28
    the scada server rack on the right
  • 00:03:32
    through a fiber line
  • 00:03:36
    via modbus tcp
  • 00:03:39
    this also shows the essential
  • 00:03:41
    communication elements
  • 00:03:43
    like communication module interfaces
  • 00:03:46
    as well as network switches
  • 00:03:52
    in addition
  • 00:03:53
    live data parameters such as irradiance
  • 00:03:58
    wind speed
  • 00:03:59
    ambient temperature
  • 00:04:01
    and all that relates to your weather
  • 00:04:04
    station on the left
  • 00:04:06
    are also being collected
  • 00:04:11
    adding more functionality such as
  • 00:04:13
    controls
  • 00:04:17
    we now have grid controllers and relays
  • 00:04:19
    that would enable the user to send set
  • 00:04:22
    points
  • 00:04:23
    and breaker operations
  • 00:04:27
    with those information now available on
  • 00:04:29
    the scada server rack
  • 00:04:32
    you can also configure it to send those
  • 00:04:34
    parameters out to the internet
  • 00:04:38
    once
  • 00:04:39
    this has been configured properly
  • 00:04:42
    your data is now accessible
  • 00:04:45
    anywhere and remote operators
  • 00:04:49
    can now access the site remotely
  • 00:04:52
    as from there we can transmit the data
  • 00:04:54
    over the internet
  • 00:04:58
    in this slide we can associate those
  • 00:05:00
    equipments to their physical location in
  • 00:05:03
    the pv plant
  • 00:05:05
    namely the operations and maintenance
  • 00:05:08
    building at the right wherein we would
  • 00:05:11
    typically place those scada servers and
  • 00:05:14
    telecommunication equipments
  • 00:05:17
    your array on the left
  • 00:05:20
    which
  • 00:05:20
    are field devices that are located out
  • 00:05:23
    in the field
  • 00:05:24
    like inverse your solar panels
  • 00:05:28
    weather stations and trackers
  • 00:05:31
    and
  • 00:05:32
    you have your substation control
  • 00:05:34
    building at the bottom
  • 00:05:36
    where you have your relays
  • 00:05:39
    and grid controllers
  • 00:05:44
    in this section we will discuss briefly
  • 00:05:46
    the core elements
  • 00:05:48
    or
  • 00:05:49
    aspects to be taken in consideration
  • 00:05:52
    when putting up a functional scada
  • 00:05:54
    system
  • 00:06:00
    first we have engineering
  • 00:06:03
    when it comes to the core
  • 00:06:05
    engineering plays a big role as this
  • 00:06:08
    involves
  • 00:06:09
    balance of the plant
  • 00:06:11
    substation automation
  • 00:06:13
    as well as network and
  • 00:06:16
    telecommunications
  • 00:06:19
    the ideal scada system should have an
  • 00:06:21
    integrated data system
  • 00:06:24
    telemetry and control systems for
  • 00:06:27
    utility interconnections
  • 00:06:29
    this should also have the support for
  • 00:06:32
    system owners
  • 00:06:34
    and
  • 00:06:35
    third
  • 00:06:36
    party data feeds
  • 00:06:38
    using opc
  • 00:06:40
    the np3
  • 00:06:42
    modbus
  • 00:06:43
    and other communication protocols
  • 00:06:48
    nowadays teleprotections and network
  • 00:06:51
    security
  • 00:06:52
    is becoming a standard
  • 00:06:55
    your scada system should have a cyber
  • 00:06:58
    security
  • 00:06:59
    best practices
  • 00:07:01
    using encryption
  • 00:07:03
    network vlan segmentation
  • 00:07:06
    and
  • 00:07:07
    permit by exception policies
  • 00:07:12
    when it comes to hardware considerations
  • 00:07:16
    a rovus scale server rack is needed for
  • 00:07:20
    large pv plants
  • 00:07:23
    virtual machines are more suitable
  • 00:07:25
    due to their flexibility and
  • 00:07:28
    manageability
  • 00:07:30
    credit controllers plc's are definitely
  • 00:07:33
    needed for controls
  • 00:07:37
    as for the weather station
  • 00:07:39
    there is already a wide range of
  • 00:07:41
    equipments we can choose from
  • 00:07:46
    if in case we need real-time automation
  • 00:07:51
    our tank is the best way to go
  • 00:07:55
    if you have a large-scale pv plant
  • 00:07:59
    distance from the substation building
  • 00:08:01
    where your equipments are should be
  • 00:08:02
    considered as they will be connected to
  • 00:08:05
    the inverters out in the field
  • 00:08:08
    this is where fiber line comes into play
  • 00:08:12
    and are being terminated through the
  • 00:08:14
    scada communications panel
  • 00:08:19
    commissioning comes next as this will be
  • 00:08:22
    the foundation of your system's
  • 00:08:24
    performance
  • 00:08:25
    throughout your system's lifecycle
  • 00:08:30
    you should have a good system acceptance
  • 00:08:33
    testing
  • 00:08:34
    procedure
  • 00:08:36
    and monitor your power plan startup and
  • 00:08:40
    lastly
  • 00:08:42
    compile your documentation and execute a
  • 00:08:45
    formal handoff
  • 00:08:46
    to your operations and maintenance team
  • 00:08:53
    on the subject of a software features
  • 00:08:57
    here we list down all the essential
  • 00:09:00
    functions of the scada software
  • 00:09:03
    it should have a comprehensive alarm and
  • 00:09:06
    event management system for example the
  • 00:09:09
    scada system quickly notifies an
  • 00:09:11
    operator that a batch of a product is
  • 00:09:14
    showing a high incidence of errors
  • 00:09:18
    the operator then can pause the
  • 00:09:20
    operation and view the scada system data
  • 00:09:24
    via an hmi
  • 00:09:26
    to determine the cause of the issue
  • 00:09:30
    on the historicization
  • 00:09:33
    scada software that utilizes the power
  • 00:09:36
    of sql databases provides huge
  • 00:09:39
    advantages
  • 00:09:41
    one big advantage of using sql databases
  • 00:09:45
    with a scada system
  • 00:09:47
    is that it makes it easier to integrate
  • 00:09:50
    into existing mes and erp systems
  • 00:09:55
    allowing data to flow seamlessly through
  • 00:09:58
    an entire organization
  • 00:10:02
    historical data from scada system can
  • 00:10:04
    also be logged in a sql database
  • 00:10:08
    which allows for easier data analysis
  • 00:10:13
    through data trending
  • 00:10:16
    for controls
  • 00:10:18
    ideally we would need a fast acting
  • 00:10:21
    and fault tolerant grid control systems
  • 00:10:25
    this should have features like closed
  • 00:10:27
    loop curtailment
  • 00:10:29
    power factor
  • 00:10:31
    reactive power and run plate controls
  • 00:10:38
    as a summary
  • 00:10:39
    the main goal of this
  • 00:10:42
    supervisory system is to monitor and
  • 00:10:45
    control equipment within the pv plant
  • 00:10:49
    and its core functions are
  • 00:10:52
    data acquisition
  • 00:10:55
    network data communication
  • 00:11:01
    data presentation
  • 00:11:08
    and lastly controls
  • 00:11:14
    these are the four
  • 00:11:16
    core functions
  • 00:11:17
    of a scada system
