DADiSP Software
Module - COMTRADE Data File Import
 DADiSP/COMTRADE
is a menu-driven module that extends DADiSP's
importing functionality, allowing users to import COMTRADE (IEEE Standard
Common Format for Transient Data Exchange) files. Designed specifically
for the power utility indiustry, DADiSP/COMTRADE imports COMTRADE data
files by converting information in the COMTRADE configuration file into
a fully qualified DADiSP header file. This header is automatically processed
by DADiSP's Import Facility, providing a complete import of data into
a DADiSP format.
Key Features
- Simple User Interface
- Fast and Direct COMTRADE File Import
- Automatic Header Conversion Preserves Important Data Properties
COMTRADE (Common Format for Transient Data) is an important IEEE standard
(C37.111) developed explicitly for the power industry. The standard defines
a common format for data files used for the interchange of various types
of fault, test or simulation data for electrical power systems. The IEEE
standard also describes the sources of transient data such as digital
protective relays, digital fault recorders and transient simulation programs
and discusses the sampling rates, filters, and sample rate conversions
for the transient data being exchanged. The C37.111-1999 standard establishes
that the following files are necessary for the data exchange: header file
(.hdr), configuration file (.cfg) and data file (.dat).
COMTRADE Header Convesrion
DADiSP/COMTRADE imports COMTRADE data files by automatically converting
information in the COMTRADE configuration file (*.cfg) into a DADiSP header
file. The header is processed by DADiSP's Import Facility to fully import
COMTRADE data into a DADiSP series.
Simple Menu Interface
DADiSP/COMTRADE runs from the DADiSP worksheet and is accessed through
the toolbar menu. The COMTRADE toolbar menu option utilises DADiSP's easy-to-use
pull-down menus which allow the user to select the COMTRADE Filename;
PTR (Potential Transformer Ratio), CTR (Current Transformer Ratio), and
the default Series Prefix. Once the COMTRADE parameters have been defined
via the module's menu system, the COMTRADE data is imported into DADiSP
using the specific data acquisition settings listed in the configuration
file.
Full Analysis System
DADiSP provides a complete analysis, display, and processing environment
using COMTRADE data. The integration of DADiSP/COMTRADE into DADiSP makes
it easy to automate data import and analysis applications completely through
SPL (Series Processing Language), macros and command files.
COMTRADE Functions
DADiSP/COMTRADE is a fully menu driven module. However, the following
functions can be used on a standalone basis to read COMTRADE files.
