  1. Upgrading Remote Access to the Analog Model Power System Amrit Dahal Ryan Litzko Client: Dr. Brian Johnson, ECE Dept. ECE 544: Control Systems and Critical Infrastructure

  2. Background • What 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 connected Courtesy: Dr. Brian Johnson Senior Design Project Description AMPS Communication Spring 2014 Senior Design Review

  5. Objectives • System upgrade to SEL3530: Real Time Automation Controller (RTAC) from SEL2030: Communication Processor. • Access to fault initiator to place controlled faults. • Download event record files • University 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 Setup • Remote desktop access • Server update • Fault controller

  8. Remote Desktop Access • Remote 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)

  9. Server Update • Now using a windows 7 server • Host website • Lab schedule • Google calendar • Documentation

  10. Fault Controller • Connection not yet established • Lack of documentation • Communication specs • Baud rate, parity, etc. • Connection process • Terminal opens empty • Keying sequence

  11. Benefits of New System • Updated to server to supported OS • No more firewall hole, more palatable to ITS. • Access to all features of the Model Power System • Easier to implement new lab assignments

  12. Drawbacks of New System • Third party software reliance • Schedule must be manually updated and confirmed by TA • Fault controller not yet available

  13. Lessons Learned • Setting up a web server • HTML • PUTTY • HyperTerminal • Documentation is important

  14. Future Work • New scheduler to bypass lab TA maintenance requirement. • Establish communication with fault controller and implement into new system • Integrate AMPS system with Real Time Digital Simulator (RTDS)

  15. Questions/Comments?
