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

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)
