Spectra DMS™ - Advanced Distribution Management Applications

In response to the various and growing needs of modern

distribution system operators, OSI presents Spectra DMS™ (Distribution Management System). Incorporating a full suite of next-generation distribution system management applications,

Spectra DMS represents a modern and comprehensive solution for many of the pressures and challenges facing the distribution

management operators of today. Spectra DMS encompasses a comprehensive and integrated set of powerful, electric distribution system management solutions that are accessible through a common user-interface with a standardized look-and-feel that allows for seamless navigation between individual solutions. These solutions are easy to use and support the complete business process for the targeted outcome, whether confined to the operations organization or extending to other areas of the utility.

Spectra DMS and its component applications empower distribution system operators and other users to monitor the

Feeder Reconfiguration – Volt/VAR Control – Spectra VVC

Spectra FR is an advanced switching solution that determines Spectra VVC empowers utilities to reduce system losses, release optimum load transfer switching procedures to improve the system capacity, improve voltage profiles and implement overall performance of the electrical distribution system. conservation voltage reduction with intelligent and optimum

management of reactive resources. Spectra VVC monitors Spectra FR enables operators to respond with quick solutions to distribution system voltage profiles and power flows and overload situations and to minimize damage to system assets, controls capacitor banks, voltage regulators and distribution correct low voltage conditions and improve customer substation transformer LTC’s, to achieve the objective of the satisfaction.desired Volt/VAR control strategy. Control strategies supported

by Spectra VVC include:! Management of reactive power flows! Management of system power-factor! Management of voltage profiles! Minimization of system losses! Conservation Voltage Reduction (for Demand Reduction)

Similar to Spectra FISR, Spectra FR utilizes a capacity/loading algorithm or optionally a power flow algorithm to analyze the impact that possible alternative switching steps may have on the system, presenting the operator with the best alternative feeder reconfiguration procedures. Utilizing the

capacity/loading algorithm, Spectra FR determines the switching procedures for relieving overloaded distribution substation and system feeder equipment/devices. For loss minimization and conservation voltage reduction,

Spectra VVC utilizes a robust power-flow algorithm to evaluate With the power flow algorithm, Spectra FR will determine a potential control actions and determine the best control action switching solution that balances system equipment loading, to achieve the desired results with the fewest number of steps. improves voltage profiles and reduces system losses. Spectra Spectra VVC enables utilities to best levelize feeder voltage FR can be scheduled to run periodically, on demand by the profiles, provide reactive power support and to reduce system operator, or triggered to run whenever a reconfiguration of the load while ensuring that adequate voltage levels are system occurs or when an unacceptable overload situation is maintained at the end-of-the-line customers.detected.
