Alternative Transients Program Features

Introducti**ATP is a universal program system for digital simulati** of transient phenomena of electromagnetic as well as electromechanical nature. With this digital program, complex networks and c**trol systems of arbitrary structure can be simulated. ATP has extensive modelling capabilities and additi**al important features besides the computati** of transients.
ATP has been c**tinuously developed through internati**al c**tributi**s by Drs. W. Scott Meyer and Tsu-huei Liu, the co-Chairmen of the Canadian/American EMTP User Group. The birth of ATP dates to early in 1984, when Drs. Meyer and Liu did not approve of proposed commercializati** of BPA (B**neville Power Administrati**) EMTP by DCG (the EMTP Development Coordinati** Group) and EPRI (the Electric Power Research Institute). Dr. Liu resigned as DCG Chairman, and Dr. Meyer, using his own pers**al time, started a new program from a copy of BPA's public-domain EMTP. Requirements of ATP development include h**esty in all dealings and n**-participati** in EMTP commerce. ATP is not in the public domain, and licensing is required before ATP materials are received (refer to Licensing).
Integrated Simulati** Modules
MODELS in ATP is a general-purpose de******i** language supported by an extensive set of simulati** tools for the representati** and study of time-variant systems.

* The de******i** of each model is enabled using free-format, keyword-driven syntax of local c**text and that is largely self-********ing.
* MODELS in ATP allows the de******i** of arbitrary user-defined c**trol and circuit comp**ents, providing a simple interface for c**necting other programs/models to ATP.
* As a general-purpose programmable tool, MODELS can be used for processing simulati** results either in the frequency domain or in the time domain.

TACS is a simulati** module for time-domain analysis of c**trol systems. It was originally developed for the simulati** of HVDC c**verter c**trols. For TACS, a block diagram representati** of c**trol systems is used. TACS can be used for the simulati** of

* HVDC c**verter c**trols
* Excitati** systems of synchr**ous machines
* power electr**ics and drives
* electric arcs (circuit breaker and fault arcs).

Interface between electrical network and TACS is established by exchange of signals such as node voltage, switch current, switch status, time-varying resistance, voltage and current sources.

Supporting Routines

* Calculati** of electrical parameters of overhead lines and cables using program modules LINE C**STANTS, CABLE C**STANTS and CABLE PARAMETERS.
* Generati** of frequency-dependent line model input data (Semlyen, J.Marti, Noda line models).
* Calculati** of model data for transformers (XFORMER, BCTRAN).
* Saturati** and hysteresis curve c**versi**.
* Data modularizati** (for $INCLUDE).
