PowerWorld Trainer Highlightsg g

• Uses PowerWorld’s industry‐leading user interface and• Uses PowerWorld s industry‐leading user interface and visualization platform

• Easy to customize for company‐specific training requirements. PowerWorld Trainer supports:– multiple one‐line diagrams and graphical system representations– full breaker topology ‐ use the actual EMS system model not afull breaker topology use the actual EMS system model, not a

planning equivalent– customizable monitors and alarms

conditional remedial action schemes (RAS)– conditional remedial action schemes (RAS)– multiple simultaneous participants: transmission operators,

generation dispatchers, etc.• Instructor may pre‐program a sequence of events to which students

must respond, or participate alongside operators

Monitors and Alarms

• Can be configured and sent from server• Can be configured and sent from server• Monitors work like filters

– Users can specify a type of device to monitor and a condition on a particular field (e.g. Bus voltage > 1.08 pu)pu)

– To make the alarms more decipherable, it is also possible to create a description of the alarm based onpossible to create a description of the alarm based on various model fields (e.g. Bus Name, Label, Nominal kV)

• When the monitor condition is met, an alarm is generated

Monitors and Alarms

Monitors: show what is being monitored and the filters gthat define limits

Alarms: show devices that violate those limits


How Trainer Works

• Architecture• Architecture– Trainer Server– Trainer Client

• Using Trainerg– Develop Training Content– Server SetupServer Setup– Client Setup

• Operation• Operation • Demo


Trainer Architecture

Traditional operator training platform does computation on the server and passes full system state; PowerWorld Trainer approach uses less network


passes full system state; PowerWorld Trainer approach uses less network bandwidth

Trainer Architecture

E h li t i t i it d l f th• Each client maintains its own model of the power system

• To avoid every client having a different state, the server managesthe server manages– Starting point– Solution options– Changes that affect system state (e.g., opening lines, changing generator outputs, …)


Event Processingg


Event Processingg

Commands are issued as inCommands are issued as in EMS environment1. Click on device1. Click on device2. Request action3. Confirm action3. Confirm action4. Message broadcast to all clients in Trainer Logclients in Trainer Log


Trainer ServerConfigure files to send to each Client

Connected Clients tab has a list of the Clients that are connected and information b t h (B ild D t d C tabout each one (Build Date and Computer Name are not populated until GetBuildDate Command is sent)

Server Log contains a list of commands


gThat have been sent and received

Trainer Server

D i d t b i l ibl• Designed to be as simple as possible– Server has no knowledge of system state– Every client is treated the same

• Primary function is to send model and solution• Primary function is to send model and solution options and forward commands

• Several options and commands have been added to support logging, recovery from errors, pp gg g, y ,and scripted behavior


Trainer Client

Th T i Cli t i t i d d i f• The Trainer Client is a stripped‐down version of PowerWorld Simulator– Only the Trainer ribbon is available, which contains mostly one‐line diagram functionsy g

– Commands that can potentially change the state have been disabledhave been disabled

• Cannot load aux files or change values through dialogs or the Model Explorerthe Model Explorer

– All changes are made through a dialog that forwards the changes to all clients via the server


forwards the changes to all clients via the server

Developing Training Content

• Develop training scenarios or exercises in PowerWorld

p g g

• Develop training scenarios or exercises in PowerWorld Simulator and/or Retriever – Models, cases (pwb): may use topology processing for node‐

b k d lbreaker models– One‐line diagrams (pwd)

• Multiple one‐lines may be used• Supports contouring, saved views, layers, dynamic formatting, emphasis filter, one‐line links, and other features

– Auxiliary files (aux): simulation options, contingencies, alarms ( i i l l)(setup in Retriever Control Panel)

– Time Step Simulation (tsb): schedule events to happen at a certain time during training simulation

• Instructor may also participate on a Trainer Client alongside trainees: manually force outages or sabotage the system


Time Step Simulation

F t h t ti d

p

• Footer shows current time and progress through simulation


Server Setup

R S

p

• Run Server program • Choose files to send

– At a minimum the case and options files should be sent• Check server configuration optionsCheck server configuration options• Start server, wait for clients to connect• After all of the clients have connected

– Send GetBuildDate command– If the build dates are the same, send the files; the “Send all files” commands sends all the selected files


Trainer Client Setup

St t th T i

p

• Start the Trainer program• Configure the Trainer client optionsg p

– Set the server address and port number to match the server configurationthe server configuration

– Set the working directory (this is where the files from the server will be stored)from the server will be stored)


Server/Client Configuration

• Server

/ g

• Server – Manages starting point– Manages solution options– Manages solution options– Manages changes that affect system state

• ClientClient – Maintains own model of system– Only certain changes made through special dialogsOnly certain changes made through special dialogs (branch status, generator outputs, generator AVR, etc.)

– Receives changes made by other clients through the server

– Monitors and Alarms: Monitor a specific device and field and log (Alarm) when it meets this condition


field and log (Alarm) when it meets this condition

Server Operation

D i th t i i i l ti th

• During the training simulation, the server may be used to:– Log events– Automatically save system statesAutomatically save system states– Restore the simulation in the event of a blackout or failurefailure


Client Operation

p

• Files are sent from the server to each client to establish a common training scenario

• When a participant interacts with the system (e.g. opens a )circuit breaker)

– a command is sent from the participant’s client to the server– the server broadcasts the command to all clients andthe server broadcasts the command to all clients, and– the power flow is solved on each client

• Commands are stored in a buffer queue so they will be li d i h dapplied in the proper order

• If there are multiple commands in the buffer queue, several may be applied together before the power flow is solved (tomay be applied together before the power flow is solved (to enhance program speed, as solving the power flow takes much more time than applying a command)
