them in an aesthetically pleasing and easily understandable manner. This display would make our SCADA system very easy to conceptualize, and it will make our system look more attractive and functional to observers. Technical approach considerations and results Virtualization Approach Software Options for a Virtual Hypervisor o VmWare Server Advantages Can get a free license Can have multiple virtual machines on 1 computer Disadvantages Minimal functionality It runs on top of an operating system so the resources used by the operating system will hinder its performance o VmWare ESX Advantages Is the operating system for the computer, minimal resource usage and overhead. Can get a free license from the university Can have multiple virtual machines on 1 computer Already familiar with this software Software is easily installed on non-server class hardware Disadvantages License only lasts 1 year. o Citrix XenServer Advantages Is the operating system for the computer, minimal resource usage and overhead. Can have multiple virtual machines on 1 computer Disadvantages No free license available, would need to pay for one. Not as familiar with this software. o Microsoft HypverV Advantages Can get a free license from the university Can have multiple virtual machines on 1 computer Is the operating system for the computer Disadvantages Not familiar with this software.

Software Selection for a Virtual Hypervisor We chose to use VmWare ESX as our virtualization hypervisor. A team member was familiar with the software and has used it before. The university also gives us a 1 year license to the software so there was no need to spend money on the software. It was also easy to install on a PC even though it usually recommends server-class hardware be used. This software also allows for virtual machine templates to be used so it would be easier for use to deploy multiple substations. Software Options for a Software Relay Simulator o Delphin-Informatika IEC 61850 Simulator Advantages Was developed with use for SICAM PAS and Siemens Relays Connected and worked with SICAM PAS Disadvantages Only 30 day trial, expensive to purchase Trial did not include full functionality Based out of Russia, little amount of support. o SISCO AX-S4 MMS Advantages Free educational license Provides a network stack for communication Disadvantages More complex than the other solutions o SystemCORP IEC61850 DLL Advantages Free Disadvantages Poor documentation Did not connect well to our system. No Support Software Selection for a Software Relay Simulator We chose to use the SISCO AX-S4 MMS as the software for simulating relays. At first we thought the Delphin-Informatika IEC 61850 Simulator would be our selection. It worked well with our system and was developed for the same hardware and software that we are using. The draw backs to the Delphin- Informatika simulator is that the trial only lasted 30 days with basic functionality and that the full license would be too expensive. We did some more research and found the SISCO simulator. The SISCO AX-S4 MMS provides much functionality as a simulator and SISCO provides a free educational license. Even though the SISCO product is more complex and will take longer to learn, it was the best option. SDMAY11-11 10
