BackgroundWhat is Analog Model Power
System (AMPS)?A system composed of various units
involved in power protection and monitoring. Transmission Model Hardware
Multiple Power Sources Variable Impedance Fault Phase shifting transformer with tap
changer control Monitoring and Protection System
Internet Security Gateway, switches, relays, Remote Control Unit (RTU), ruggedized computer
Ethernet connection Fault Controller
Serial connectedCourtesy: Dr. Brian Johnson Senior Design Project Description

ObjectivesSystem upgrade to SEL3530: Real Time
Automation Controller (RTAC) from SEL2030: Communication Processor.
Access to fault initiator to place controlled faults.
Download event record filesUniversity Information Technology Services
(ITS) and College of Engineering (CoE) Cyber Security Compliance
Additional opportunities to conduct lab exercises
6
Old Remote Control Setup- Login website allows access to fault initiator.
https://mps.ece.uidaho.edu- Schedule - SEL 2030- Change Password - Fault Controllers
System Setup:- Server host on Windows XP (with Windows 2003 server)- Firewall hole created in UI server to allow connection to MPS Remote Control server host computer
7
New System SetupRemote desktop accessServer updateFault controller
8
Remote Desktop AccessRemote Login Via Team Viewer
Free and simple to use (drag and drop – downloading)
Works with Microsoft, Apple, and Linux Host computer has command
Host must be on, software must be enabled, connection can be terminated at anytime via Lab TA.
Secure connection Whitelisting ID, password protected, encryption
based same level as https Other features (IM and video conference)

Server UpdateNow using a windows 7 serverHost website
Lab schedule Google calendar
Documentation
10
Fault ControllerConnection not yet established
Lack of documentation Communication specs
Baud rate, parity, etc. Connection process
Terminal opens empty Keying sequence
11
Benefits of New SystemUpdated to server to supported OSNo more firewall hole, more palatable to ITS.Access to all features of the Model Power
SystemEasier to implement new lab assignments
12
Drawbacks of New SystemThird party software relianceSchedule must be manually updated and
confirmed by TAFault controller not yet available
13
Lessons LearnedSetting up a web serverHTMLPUTTYHyperTerminalDocumentation is important
14
Future WorkNew scheduler to bypass lab TA maintenance
requirement. Establish communication with fault controller
and implement into new systemIntegrate AMPS system with Real Time Digital
Simulator (RTDS)
