Eaton's Yukon Volt/Var management software solution monitors real-time voltages, watts and VARs from LTCs, regulators, capacitors, medium voltage sensors and additional monitoring points such as customer meters and assess the characteristic of energy delivery. Based on that assessment, the Yukon Volt/Var Management software will issue a control command to a load tap changing transformer, a voltage regulator or a capacitor bank automatically without operator interaction. The solution improves the distribution system efficiency and mitigates operational issues. The Yukon Volt/Var management software solution is one of Eaton's grid automation system solutions.
Learn how flattening your voltage profile and minimizing your VAR flow can improve your bottom line.
Easy to implement because data requirements are simple and easily imported
Integrates to 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 the communications messages through command response analysis
Integrated to 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
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 during the middle-night by cycling the state of the capacitor bank and 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 failed
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 analyze and operate the devices to which it continues to communicate.
If 30% of the device measurements are stale and the configurable percentage of stale device measurements is 20%, Yukon will disable automated control
Provides many standardized 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 regarding capacitor bank operations, alarms and conditions, excessive bank operation counts as well as the report identifying failed capacitor banks
Also reports on communications and operational statistics
Eaton recommends deploying Yukon in a three-tier computing architecture as recommended by NIST SP800-82
This architecture separates the database, application and presentation services to independent servers and trusted security levels within the utility
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 unauthorized application from accessing field devices, and protecting the enterprise from the field
Can be deployed using the high availability, disaster recovery and backup processes already defined by the utility's IT team
A hierarchal relationship is established between the Yukon Volt/Var Management solution core services that provide a clean application shutdown and organized dependency failover if a failure of some type occurred
