Automatic Generation Control (AGC)
AGC is a feedback control system that regulates the power output of electric generators within your control area so as to maintain scheduled system frequency and/or power interchange within predetermined limits. Includes Economic Dispatch, Reserves Monitoring, and Interchange Scheduling.
Advanced Metering Infrastructure (AMI) Interface
AMI Interface allows the SCADA system to obtain meter data by interrogating the AMI system using the MultiSpeak protocol. The user can request readings from any meter and display the data on-demand in the WorldView map.
Users can also define schedules for the SCADA system to automatically interrogate the AMI system for specific meter data. The received data is stored in the analog points. This data can be used by other applications such as voltage readings for voltage reduction algorithms.

Automatic Vehicle Location
AVL is an application that enables the location of GPS transponder equipped vehicles to be displayed on a map within Worldview. The location of the vehicle is updated real-time within Worldview so the user can see the actual location of the vehicle on the system map.
Command Sequencing
Command Sequencing is an easy-to-use high-level programming language which is specifically designed to be used with Survalent systems. It allows you to define and execute programs which use database points as variables. Command Sequence programs can be used for calculations, open-loop control or switching sequences and for closed-loop control.
Control Panel
Survalent's Control Panel allows you have an IED represented by an image of the IED's front panel, on which dynamic elements are superimposed. These dynamic elements not only display current values of the points in the IED, but also allow you to issue controls and setpoints.
Database Transcription
For bi-directional transcribing of SCADA data into relational databases. Target databases that are supported are Microsoft Access, SQL Server, Sybase, and Oracle. The type of data that can be transcribed includes: current values, historical data, operation messages (including alarms), and event logs (including SOE).
Disturbance Capture
This functionality monitors changes to all analog and status points periodically, defines events that trigger disturbance data captures, monitors disturbance triggers and generates disturbance capture files.
Event Data Recording
Event Data Recording records all status changes, operator controls and Sequence of Events (SOE) data. Non-SOE events are time-stamped to the nearest second. SOE events are stamped to the nearest 1 millisecond (subject to the capabilities of the RTU).
External Alarm Bell
External Alarm Bell is for operations under noisy conditions. The application can control (activate/de-activate) several different external alarm bells based on alarm priorities for any of the different alarm zone groups.
External Clock Interface (GPS)
External Clock Interface synchronizes the computer time to that of the external (GPS) clock every minute. An alarm is raised if the SCADA system cannot read the clock.
Fault Data Recorder
Fault Data Recorder program is an application that you can use to upload and record fault data from SEL relays. The application consists of a Fault Recorder editor and an executive program. The editor allows you to identify fault data points as well as other points and parameters that are involved in the process of retrieving the fault data. The executive program does the actual retrieval (i.e. detection, uploading and storage) in cooperation with the scan task.
IED Wizard
IED Wizard is a tool that automates the creation of the database points for supported IEDs. The database points are created for the SCADA system, and the mapping can be automatically downloaded to the RTU for an IED that is slaved to a Scout. Users can create their own templates, or use one of the existing Survalent-developed templates.
ICCP
ICCP (Inter-Control Center Communications Protocol) is an industry-standard protocol designed to share information with different vendors' computer systems. It is typically used for data transfer between two or more SCADA/EMS master stations.

Load Estimation
Load Estimation application works in conjunction with Survalent's Load Forecasting application. It uses the scheduled load forecasts to continually estimate the present value of the load point. By means of a special calculation function, the estimated value can be used to substitute actual telemetered values during periods where telemetry has failed. Note: Load Forecasting License is required.
Load Curtailment
Load curtailment in Windows SCADA makes use of a high-level "supervisory" program to monitor conditions on your system and make decisions about when and how load shedding will be required. It then uses a low-level "executive" program to execute the desired strategies and perform the controls necessary to shed the desired load.
Master/Slave Alarm Suppression
Master/Slave Alarms Suppression allows a defined hierarchy of primary/secondary (master/slave) alarm point relationships. These relationships may be used for either alarm suppression or group acknowledgement, or both.
MultiSpeak
Multispeak is an industry-wide open initiative sponsored by the National Rural Electric Cooperative Association (NRECA) to facilitate development of software interfaces needed by rural electric co-ops and munis. It has developed uniform interface definitions for data exchange among commonly used software. Survalent provides Multispeak 3.0 compliant interfaces to other Multispeak-compliant third party applications.
NDA API
Network Database Access (NDA) is a client/server protocol that was developed by Survalent. The NDA API (application programming interface) is a library of functions that allows PC application programs to access the SCADA system using the NDA protocol. This API is provided in the form of a DLL (dynamically linked library) that is installed on the PC. The underlying network protocol used is TCP/IP.

This program also contains the required interface to OSI's PI historian. One software module is loaded onto the Survalent server, and another module is loaded onto the PC that is running the OSI software. This allows database points (typically historical data and run-time data) to be exported to the PI database.
OPC Client/Server
OPC stands for OLE (Object Linking and Embedding) for Process Control and it is a non-proprietary technical specification that defines a set of standard interfaces based upon Microsoft's OLE/COM technology. The OPC Client/Server application includes options for both OPC Client and OPC Server to make possible interoperability between automation and control applications, field systems and devices, and business/office applications.
Operations & Outage Accounting
The Operations and Outage Accounting function is based on the Event Data Recording facility. The event data recording facility records all status changes and control operations in an event data file capable of storing events for up to 30 days. Every night at midnight, an accounting program scans the previous day's event data to generate that day's accounting information. Special-purpose report programs produce operations and outage reports. An equipment editor allows you to define the devices for which you want operation and/or outage accounting.
Operator Training Simulator
Operator Training Simulator (OTS) consists of a second independent copy of the SCADA system operating with simulation programs instead of scan tasks. The OTS system provides facilities that allow the instructor to maintain many different copies of the database to select any of these to use for a training session and to execute multiple simultaneously running event scripts.
Power Factor Control
The Power Factor Control feature in Windows SCADA is responsible for monitoring and correcting the power factor at specified locations within the power system. First, it monitors each of several specified "billing points", which usually represent the locations where power is supplied to your system. These locations normally have telemetry of real and reactive power, and perhaps also the power factor. It is usually the power factor at these locations that is most important to the user.
Remote Alarm Annunciation
The ability to send an e-mail, paging, SNMP, and SMS text message for specified alarms. The user can define which points are annunciated in this fashion, and for each point, which alarms (e.g., which states for a status point and which limits for analog point). When using SMS text messaging, alarm can be remotely acknowledged using a password.
SCADA Add-In
A Microsoft Excel and Microsoft Access option allows the user to export current and historical data from the SCADA system into Excel. All point data fields (not just values) are available to export. The menu commands are available from the standard menu bar within MS Excel or MS Access. SCADA Add-in is compatible with: MS Windows 98, 2000, XP, Vista, and Windows 7; MS Office 98, 2000, XP, 2003, and 2007.
SCADA Replicator
Real-time replication of the SCADA database to SQL. Replicator is plug-n-play, no fields to setup, and maintenance free. The entire database is replicated and made available in SQL for access by other systems or applications. SCADA Replicator is one-way, which provides added security for customers that do not require bi-direction dataflow.
Short-Term Load Forecasting
This application is based on matching historical load and weather data. The editor allows you to enter hourly weather forecasts for up to 24 hours, and daily forecasts for up to a month. The algorithm takes the five best historical matches, and averages the resulting load curves to produce the forecast.
Simple Network Management Protocol (SNMP)
This scan task is designed to communicate with one or more devices using the Simple Network Management Protocol, a protocol used to manage devices connected to a TCP/IP network.
Switch Order Preparation
A switch order is a sequence of steps involving both switching operations and tags that produce conditions for which a guarantee may be issued. Each switch order can contain up to 200 steps. Guarantees are database forms that allow you to define, issue and surrender condition guarantees complete with tags. (Guarantees are also commonly known as clearances.) Each guarantee can have up to 50 tags associated with it.
System Configuration Status
A topology processor that calculates the energized/de-energized status of electric, gas and water line sections, and displays them on world maps. The calculation is based on the topology of the distribution system and the current status of breakers and valves. For an electrical line section, the system supports 3-phase distribution, and computes the status of each phase independently, such that line sections that are downstream of non-ganged switching devices may contain a mix of energized and de-energized phases. The user can specify colors for "partially energized" or "partially looped" etc. SCS includes a feeder trace function that allows the user to select a trace color and have the extent of a feeder highlighted in the selected trace color. Multiple simultaneous traces in different colors are supported.
Virtual RTU
Virtual RTU application allows for quick and easy setup of a virtual device that can be polled by another master station via DNP3 and MODBUS protocols. Points are easily added to the Virtual RTU with the Drag-n-Drop Point Browser. Complete Datasets can be created and assigned to multiple Virtual RTUs. This means that the same data can easily be sent to more than one client system without having to maintain duplicate dataset definitions for each Virtual RTU.
Voltage Reduction
Voltage Reduction automatically lowers and raises your voltage regulators, to achieve voltage reductions in accordance with supervisory logic you provide.
