1 GE Energy Digital Energy GENe DMS GE Energy s GENe Distribution Management System helps utilities optimize the performance of their networks. GENe DMS software reduces costs via intelligent peak-shaving and a more effective use of network assets; it pro-actively improves network reliability while significantly decreasing customer outage periods. Why choose GENe DMS? With today s technology, a utility can derive greater benefits from a GENe Distribution Management System than ever before. Two such advances are the installation of Smart Meter technology and the advances made in telecommunications provide better and broader communication with field devices. GENe operating system-wide results in the following: Dramatically reduced time to restore outaged customers: GENe s Fault Detection, Isolation, and Service Restoration (FDIR) function recommends switching steps to restore upstream and downstream customers within seconds of locating the fault, thereby bringing customers back on-line as quickly as possible. Significantly improved reliability: GENe s preswitching validation functions provide up-to-thesecond information on the impact of proposed switching actions ensuring unwanted results are avoided. Much faster preparation of planned switching: GENe s Automatic Switching Order Writer proposes switching actions based on the real-time state-ofthe-network and near-term loading. Its rule-based engine generates the corresponding switching order, including procedural steps that will reflect your utility s way of operating. Network Model Management Connectivity Analysis Power Flow Analysis Distribution State Estimation FDIR (Fault Management) IVVC (Integrated Volt-VAR Ctrl) Reduced peak demand: GENe s Integrated Volt- VAR Control application accurately targets voltage reduction in order to reduce load in periods of high demand. Fault Level Analysis Distribution Optimization GENe MIDDLEWARE Switching Management Outage Management SCADA Training Simulator Increased network efficiency: GENe reduces losses by providing real-time recommendations on how to reconfigure your network to minimize losses and balance loads.

2 The GENe DMS can support networks comprised of millions of devices, delivering the same exceptional performance it does for smaller networks. Graphical network colouring is updated within two seconds of a change in connectivity. GENe DMS and Smart Grid GE Energy is avant-garde in its implementation of Smart Grid principles in its applications. Our flagship FDIR application, first deployed in 2003, is a key component of a self-healing network. It includes an automatic detection of faults, and an automatic execution of upstream and downstream restoration switching. This means that more customers are restored more rapidly, reducing outage minutes and improving Quality of Service Indices. Since 2003, FDIR has been continuously improved and expanded upon with its deployment on new projects. Other examples of supporting a Smart Grid solution within the DMS include achieving network optimization via Volt-VAR Control or load transfers and supporting distributed generation within the DMS. At GE Energy, we recognize the potential of the Smart Grid initiatives and are committed to providing its benefits to our customers. Key features The GENe DMS system offers many key features.

3 GE Energy developed and deployed one of the world s very first DMS in 1991, which included a three-phase connectivity analysis and load flow. We have since expanded our offering to include a variety of applications. GENe DMS is now deployed around the globe. Effective User Interface maximizing productivity The GENe DMS User Interface is designed to meet the following main objectives: Allow the user to quickly assess the state of the network. This means different things to different types of users, but the unifying theme is to help focus their attention where needed. Give users the necessary feedback, for example in terms of potential consequences, ensuring that they can make intelligent and informed decisions. Reduce outage times The GENe DMS portfolio includes FDIR. This application is fully integrated with the GENe Switching Management application, so that within seconds of detecting a fault, GENe can propose switching steps to restore upstream and downstream customers, rapidly reducing the number of outaged customers and dropping the total outage minutes. On approval by the user, GENe translates these switching instructions into a full-fledged Switching Order that includes procedural steps such as issuing tags and safety documents, in order to meet the Operating Standards of the utility. Assist users in performing daily tasks as quickly and efficiently as possible and automating routines, while still giving them the necessary control. Ensure that the user can investigate emergency situations quickly to assess the extent of problems, evaluate options, and take action. The GENe DMS User Interface offers very rich graphicaldisplay capabilities, including geographic displays and schematics that present results from a variety of applications. The graphical displays can present Connectivity Analysis as well as Load Flow results including colouring of violations, which indicate the extent of an outage and identify the faulted device. These displays are complemented by a set of tabular displays that present application results in an intuitive fashion. GENe supports full navigation between tabular, graphical, and schematic displays. Intelligent peak-shaving Peak-shaving is realized via voltage reduction or loss optimization which can be achieved by a number of applications. The Integrated Volt-VAR Control (IVVC) recommends controlling Shunt capacitor banks and Transformer and line regulator tap positions and/or their automatic voltage regulator set points. IVVC s main objective is to either minimize the losses or minimize the voltage depending on constrains that are set by the user. IVVC recommendations can be issued automatically and directly to control field equipment.

4 A solid DMS base that can be tailored to meet your needs. The multi-faceted applications that make up the DMS provide you with tools that improve productivity and profitability. resulting violations and proper tagging are respected. A Web service is also available which enables authorized users to create an Application for Work. An Application for Work automatically appears to the authorized DMS user as a pending switching order with the proper fields populated. SMS supports the archival of completed switching orders, as well as the restoration and viewing of previously archived switching orders. Voltage Reduction and load shedding are applications that temporarily shed loads or drop the voltage in the network by a certain percentage set by the user. GENe also offers load transfer applications that optimize the use of your assets by recommending switching actions that minimize the losses or relieve overloading situations that could be present in the network. Access to all switching management functions is controlled via the mechanism of user roles and privileges. This approach enables individual utilities to assign responsibilities associated with the various functions to different types of users. SMS maintains a detailed chronological audit trail that records and highlights all changes made to a switching order after approval. Planned switching made easy The GENe Switching Management Subsystem (SMS) provides users with an integrated environment for preparing, validating, approving, and executing switching orders. SMS is the application of choice when maintenance of power system equipment, emergency isolation and restoration, load transfers, or other such activities are required and access to power network equipment is necessary. Switching order steps can be created manually, recorded from graphical operations, or created automatically by the planned outage management services. The automated switching order method produced by the switching advisor ensures certain constraints such as no

5 The vast amount of data available to utilities today is only helpful if it can be effectively managed. Part of the GENe solution is to successfully manage critical data in the most effective manner. Critical to DMS success data management The single most important factor that determines that you are getting the most out of your DMS is effective and efficient data management. The GENe GIS Gateway can interface to a wide variety of Geographic Information Systems, and will help you to streamline the process of keeping your DMS data up-to-date, both during initial build of the DMS network and through highly optimized incremental imports. GE Energy has a great deal of experience in helping utilities to put practical data management systems in place. A solid, proven base that meets your needs GE Energy recognizes that the amount of telemetry available varies from one utility to the next. To accommodate this variable, we have designed our GENe DMS to allow utilities with far less field information to derive significant benefits. While our applications are designed to respond to telemetry and to issue controls directly to the field, they can also be configured to work with manually entered data to produce recommendations. The GENe DMS applications can be configured differently on the various parts of your network according to the level of telemetry; the configuration can be adapted as you expand your field communications. GE Energy offers a solid DMS base with an extensive proven array of DMS applications; and we are always willing to develop new products tailored to specific utility needs. Our high rate of repeat customers is a very strong endorsement of both our product and our people. Let us put our experience to work for you.
