DIgSILENT PowerFactory Connectivity
DIgSILENT PowerFactory has the ability to interface directly with a number of external programs and hardware structures, such as GIS (Graphical Information Systems) and SCADA (Supervisory Control And Data Acquisition) systems. Additionally, A/D interfacing capability with the PowerFactory Monitor monitoring system is also possible.
The DIgSILENT PowerFactory DOLE software was developed in part to allow data conversion from programs, but also to meet the increasing demand for interfacing with GIS and SCADA systems. The DOLE structure is quite simple and allows users to custom design their own interface protocols, which enables compatibility with any number of SCADA and GIS systems.
SCADA Interface
Interfacing with SCADA gives direct access to dynamic and/or static SCADA data, allowing both real time system analysis and incident analysis from previous snapshots. As DIgSILENT PowerFactory integrates topology processing already, interfacing can be made on a point to point relation using foreign database keys.
GIS Interface
DOLE can also be interfaced with any existing Graphical Information Systems (GIS). For this purpose DIgSILENT PowerFactory provides the user with an auxiliary EXCEL file that permits data conversion from the GIS to DOLE formats. Figure 10.1 illustrates a typical GIS to DOLE data conversion program.
Engine Mode
DIgSILENT PowerFactory may be operated as a background process in situations where it is integrated into GIS or SCADA systems. This capability also permits the remote control of PowerFactory via the GIS or SCADA system directly, in what is called "Engine Mode". The basic advantages of this approach are summarized as follows:
- Engine Mode is an in-built feature available in all DIgSILENT PowerFactory package configurations, at no extra cost.
- All PowerFactory functionality is available in Engine Mode.
- Simple integration with the GIS or SCADA system.
- PowerFactory software upgrades will not require complex re-integration procedures on the source code level.
- The PowerFactory MMI can be activated for data maintenance, operation and display purposes at any time in Engine Mode.
A/D Interface Capability
The DIgSILENT PowerFactory A/D interface with the PowerFactory Monitor monitoring system, is the latest development in integrated operation supervision, fault recording and test analysis evaluation. This is achieved via the generic model frame and VI (Virtual Instrument) environments, and may be utilized to:
- Implement analog inputs with for up to 5 kHz per channel
- Perform signal normalization and correction
- Calculate RMS values and phasor quantities
- Realize soft-transducers for active power, reactive power, frequency, speed, frequency spectrum, system oscillation analysis and many other quantities
- Determine trigger conditions for fault recording
- Perform permanent monitoring
- Detect system oscillations
- Analyze and supervise connection conditions
- Direct interchange of signals with the model identification blocks.
