CalculatorThis convenient soft logic utility can perform applications such as substation level interlocking, feederinterlocking, and converting digital inputs to control outputs for driving a map board. Program the system tocontrol analog inputs and outputs and digital inputs and outputs based on the result of configuredmathematical and logical expressions. Create expressions using a library of constants, operators andreferences to system database points, as well as comparison operators, logic operators, logic bit operators,math operators, sign operators and expression delimiters.

Digital Fault RecorderThe Digital Fault Recorder system based on the D25 and integrated Substation Control System is aneffective way to accurately record and analyze substation events while avoiding the excessive added costs ofstandalone digital fault recorders. This scalable system can accommodate virtually any number of analog ordigital channels by employing peer-to-peer communications to cross-trigger a set of D25s. This allows youto collect a full set of data on the condition of your network.

Through the PC-based DirectView and PowerLink workstation viewers, you can get a virtual snapshot ofthe system at the time of the fault and trace the incident with dexterity. You can clearly determine the order of events, and the performance and health of the breakers. The DirectView tool makes it easy for youto zoom in on and compare event records. With these capabilities as well as on-line configuration, uniquede-trigger functions and 240 cycles of storage, you no longer need to travel to the site to carry outpost-fault analysis.

Enhanced Load Shed ControlDuring an overload crisis situation, you can count on our Enhanced Load Shed Control program to maintainsystem operation within stable limits. The GE system can rapidly shed load at select locations by removingone or more feeders from service by disconnecting the feeder’s breakers. Once the system is stable again,the breaker can be closed by a command from the master station or by an operator through Wesmaint, orby some other special application.

Load and Dead Station TransferThe Load and Dead Station Transfer application works to maintain system efficiency by monitoring anetwork of substations and moving load off of overloaded transformers to other stations in the electricalnetwork as required. The application detects when a transformer reaches a predetermined overload setpoint, then transfers load to stations that have unused capacity. The application also automatically attemptsto restore power to feeders that lose their primary supply station. The operator can set the routine toconfirm switching operations prior to execution or to be in fully automatic mode. Load transfer is a provenway to postpone construction of new substations by reducing the overload on existing stations.

and operational trends of transformers, load tap changers and breakers. By remotely monitoring primarysubstation equipment, system operators can be alerted to impending problems in order to avert, or at leastminimize, system outages, especially during periods of peak loads.

Avoid catastrophic equipment failures by monitoring the health of transformers, shunt reactors, currenttransformers and bushings for key variables such as load current, dissolved gases in oil, load tap changermonitoring, load tap changer control, moisture in oil, partial discharge, top oil temperature, ambient temperature,pressure of the inert air system, hottest spot calculation, cooling efficiency, and cooling control. Integratedtransformer monitoring contributes to enhanced system reliability and safety, operations and maintenancesavings, early warning of equipment failures, and optimized use of capital equipment.

DISTRIBUTION AUTOMATIONFeeder networks are direct lines to your customers! Whatever the cause, power outages frustrate and infuriatecustomers. Your quality of service affects their quality of life. Retain customer loyalty by keeping the lights on.

“A recent GE Energy Services analysis revealed that the fiscal justification of feederautomation can put $US1.9 million annually back into the utility’s pocket!”

Auto-SectionalizingAuto-sectionalizing is proven to reduce your outage frequency rate. The scheme works automatically to isolatefaults on distribution circuits and keep the lights on for as many customers as possible. When there is a load sidefault, the feeder IEDs, located at motor-operated switches up to ten miles apart along a distribution network, willimmediately detect and locate the over current, and automatically open the necessary sectionalizing switches toisolate the faulted section of the feeder, and try and correct the fault. Since this application resides on the feederIED, the auto-sectionalizing acts with or without communication with the master station, and it can beimplemented at new or existing switches. Utility field data demonstrates that auto-sectionalizing adds more thanfour months to Sustained Average Interruption Frequency Index (SAIFI) performance. This application is amigration path to our auto-restoration application which targets reduced outage duration.

Auto-RestorationIdeal for large commercial or industrial facilities that rely on a constant power supply, our auto-restoration scheme can reduce outages to less than a minute. This patented load transfer schemeautomatically locates and isolates faults on a feeder, qualifies the ability to restore load based onsubstation and feeder data then quickly restores power to unfaulted sections by supplying power fromanother source. System operators are kept informed of switch operations. Auto-restoration supportsmultiple seasons, modes of operation, circuit groups and complex feeder topologies.

Distribution Capacitor Bank ControlYou can gain an effective 1 MVAR of reactive support during peak loading periods on a givendistribution unit (transformer and feeders associated with that transformer) simply through the moreefficient use of already installed banks! Improve the control of your distribution capacitors bycoordinating capacitors based on the needs of the high side of the distribution substation transformer.As the power factor of the system is improved, the total current flow will be reduced and losses will bereduced. This permits additional load to be served by the same system. Holding the system closer tounity power factor also increases system stability. Typical payback for this system is less than twoyears! In addition, the system automatically alarms for blown fuses on capacitor banks saving manyutility worker-hours checking for blown fuses.

Fault Detection and AlarmingGE feeder IEDs integrate the functions of many traditional and relatively expensive devices such astransducers, fault detectors and indicators. By avoiding these discrete components in your distributionsystem design, you can drastically cut installation, commissioning and maintenance costs. All thewhile, the GE feeder IEDs provide reliable, full-time monitoring of distribution circuits and relevant faultinformation and alarms that allow you to quickly identify faults and minimize downtime. Specifically,detect both phase-to-phase and phase-to-ground faults, determine whether the protective deviceclearing the fault has successfully reclosed or locked out, and monitor the presence or absence ofvoltage and load current following a fault clearing operation.

Fault LocalizationLocate and isolate faults in seconds – not hours – and greatly reduce customer outage times! The FaultLocalization application is a fully configurable software package that provides fault detection, locationand graphical animation information within a GE system. In a typical system, the Fault Localizationapplication will query information retrieved from remote GE feeder IEDs concerning fault detection todetermine the state of a particular power distribution network. The application maintains an updatedstate of the entire distribution network; this allows the information to be accessed by a user through agraphical user interface to visually determine the condition of the distribution network.

Tri-Phase Unbalance DetectionMonitor voltage and current values from various field devices, such as RTUs or meters, based onprogrammable settings. Capabilities include detecting phase unbalance for voltage and current, andloss of phase for voltage and current, monitoring selective phase for voltage and current, andmeasuring specified time intervals of selected phases.

ENHANCED SCADAThese invaluable programs carry out fundamental functions within the SCADA system. Althoughthey are simple in themselves, these SCADA applications are indispensable for efficientlycollecting and coordinating real-time and/or historic data for use by other automation applications,the master station or operator monitoring and control.

Accumulator FreezeDetect status changes initiated by other GE applications. One or more accumulators can be frozenwhen a status input changes state and/or automatically on a configured time interval, for example,once an hour. An optional control output can be operated to externally indicate the accumulatorshave been frozen.

Analog ReferenceThe Analog Reference application is a simple way to monitor the status of analog input fielddevices. It monitors analog input points that are connected to analog input hardware, andprovides the system database with pseudo analog values. These values represent either correctlyfunctioning analog input hardware (good reference value), or failed analog input hardware (badreference value).

Communication WatchdogThe Communication Watchdog monitors the state of communication between a GE system andconnected IEDs. When the GE system is attempting communication with the IEDs, theCommunication Watchdog can indicate whether the devices and/or individual points are on-line or off-line. In a redundant system, the Communication Watchdog indicates which physical unit isactive and shows the current readiness state of the secondary unit. All indications can be used toraise alarms, if desired.

Data Change DetectionSend indications to other applications whenever changes occur on user-defined groups of points.This application can monitor multiple groups of points, and toggle digital inputs if any changesoccur within the user-defined groups. Digital input, digital output, counter, analog input, andanalog output groups can all be monitored.

Event StorageStore up to seven days of events in the GE device’s Non-Volatile Memory (NVRAM) for access byother applications. Accumulator and analog point values can be queried and stored on aconfigurable time interval. Data is time and date stamped, as it is stored. Locally and remotelydisplay and print the stored data using Wesmaint.

SOE Local LoggerLog sequence of events data by monitoring any subset of digital inputs. As time-tagged statuschanges occur, all or a subset of the events can be printed at a local printer or stored in a file onthe RTU to be uploaded at a later time. The log includes an alarm description, point number, dateand time (to the nearest millisecond).
