ANATEM - Analysis of Electromechanical Transients

Introduction

ANATEM (Analysis of Electromechanical Transients) is the most used software in Brazil to analyze the dynamics of power systems. It is destined to the analysis of large disturbances in power systems, comprising the periods of transient and dynamic stability. 

 

It has a great modeling flexibility and accuracy, especially the User Defined Controls (CDUs), which allow modeling the dynamic characteristics of its main controllers. ANATEM stands out for its robustness and reliability and interacts with the software ANAREDE (Analysis of Power System Networks) and with the auxiliary programs PlotCepel (a tool which allows the visualization of results in graphic displays) and CDUEdit (a tool for creating new CDU's via graphic interface). The Anat0 application, which is currently incorporated into the ANAREDE program, aids the simulation of large systems in ANATEM and also performs the transient analysis in T0+.

 

Among the several studies that may be performed with ANATEM, some stand out such as those that take into consideration, in addition to the synchronous machine model, induction machine representation, functional loads, High Voltage Direct Current (HVDC) links, Flexible AC Transmission System equipment, relays, wind generators, Special Protection System (SEP), CDU controlled sources and Load Relief Regional Scheme (Erac).

 

The graphic interface of ANATEM allows the preparation and automatic execution of contingency analysis, integrates a post-processing tool for the inspection of the results obtained in the automatic contingency analysis and allows the execution of parallel cases if there is the availability of multiple cores or processors in the computer. The network data files to be used in ANATEM are available for download in some public sector institutions' websites.

 

Among the main users of ANATEM are: public sector entities, such as the Electric System National Operator (ONS) and the Energy Research Company (EPE); the Brazilian Ministry of Mines and Energy (MME); the Eletrobras companies; generation, transmission and distribution agents; big industrial consumers; independent producers; universities (student versions) and consulting companies.
