DADiSP / COMTRADE

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.

Simple Menu Interface

DADiSP/COMTRADE runs from the DADiSP worksheet and is accessed through the toolbar menu. The COMTRADE toolbar menu option utilizes 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.

Requirements

DADiSP/COMTRADE requires DADiSP 6.0 B14 or higher. Contact us for information about updating your current version of DADiSP.
