| LOW COST OF OWNERSHIP |
Easy to implement because data requirements are simple and easily imported Integrates with external systems because it supports industry integration standards and protocols Easy to maintain because it flexibly supports different types of communications networks and third-party LTCs, regulators and capacitor bank controls Validates the operation of message communication through command-response analysis |
| EMS/ADMS/SCADA INTEGRATION |
Integrated with several types of EMS/SCADA systems Typical and recommended integration is via DNP 3.0 protocol Will poll DNP data from the EMS/SCADA system via DNP 3.0 master/slave integration to retrieve substation data |
| OPERATIONAL VALIDATION AND ALARMING |
Supports additional features that enable cost-effective maintenance and administration of an automated system Tracks asset maintenance and troubleshooting information Automatically flags capacitor banks for testing, either due to a testing schedule or an identified operational failure Will test the capacitor bank at light load overnight by cycling the state of the capacitor bank, verifying the operation by monitoring the VAR value changes. If an unexpected VAR change is seen on one or more phases, the Yukon volt/VAR management solution will flag that capacitor as having failed |
| LOSS OF COMMUNICATION |
Will tolerate a number of stale device measurements based upon a utility-specified configurable percentage If 10% of the device measurements are stale and the configurable percentage of stale device measurements is 20%, the Yukon solution will continue to analyse and operate the devices it communicates with If 30% of the device measurements are stale and the configurable percentage of stale device measurements is 20%, Yukon will disable automated control |
| HISTORICAL REPORTING |
Provides many standardised reports necessary for system administration Yukon has a built-in, intuitive reporting interface that can mine any archived data from the database, along with useful configuration information Report templates exist to present data on capacitor bank operations, alarms and conditions and excessive bank operation counts as well as identifying failed capacitor banks Also reports on communications and operational statistics |
| SERVER ARCHITECTURE |
Eaton recommends deploying Yukon in a three-tier computing architecture, as recommended by NIST SP800-82 This architecture separates database, application and presentation services into independent servers and trusted security levels within the utility company Firewalls are used to set up segregated zones and manage the flow of traffic between these zones This architecture physically and logically separates the computing functions, with the goal of preventing an unauthorised application from accessing field devices and protecting the company in the field |
| DISASTER RECOVERY AND HIGH AVAILABILITY |
Can be deployed using the high availability, disaster recovery and back-up processes already defined by the utility company’s IT team A hierarchical relationship is established between the Yukon volt/VAR management solution core services, providing a clean application shutdown and organised dependency fail-over if a failure of some type occurs |
