DADiSP / Comtrade 2.3
COMTRADE Data File Import Module
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 Conversion
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.
COMTRADE ASCII and Binary Formats
Both ASCII and binary COMTRADE file formats are supported. The
original or revised file specification is automatically detected
and fully processed. PTR (Potential Transformer Ratio) and CTR
(Current Transformer Ratio) scaling factors are applied to the
appropriate analog channels.
Simple Menu Interface
DADiSP/Comtrade runs from the DADiSP worksheet and is accessed
by a press of a button. The COMTRADE user interface displays
important file information and allows for individual channel
selection. COMTRADE time and count channels are optionally
supported. Once the COMTRADE parameters have been defined, the
COMTRADE data is imported into DADiSP using the specific data
acquisition settings provided in the configuration file. The imported
channels can be plotted for immediate display.
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.
Requirements
DADiSP/Comtrade requires
DADiSP 6.7 B01 or higher.
