Electrical Networks

The Electrical Networks Department focuses on the development of software for power system operation and planning, special studies and training.

The computer programs developed by the department, such as ANAREDE (power flow), ANATEM (Transient Stability Analysis), ANAFAS (short circuit calculation), HarmZs (Harmonic Analysis), PacDyn (Small Signal Stability Analysis), FLUPOT (optimal power flow), NH2 (reliability analysis) and PLANTAC (
Transmission Planning Considering the Economic Value of Reliability), meet the needs of studies of the agents that act in the Brazilian electricity sector. In addition to Eletrobras enterprises, the Center also provides software to the Ministry of Mines and Energy and industry organizations, such as the Electric System National Operator (ONS), the Energy Research Company (EPE) and the Brazilian Electricity Regulatory Agency (ANEEL). Generation, transmission and distribution companies, state owned and private also use Cepel’s software, as well as consultants and universities. Cepel develops specific actions oriented to engineering education, providing free reduced versions for universities.


Using its own software, Cepel develops special studies, like the ones related to the large hydroelectric projects in the Northern region, such as Madeira and Belo Monte, and those related with the Brazil-Uruguay interconnection.


Cepel offers, on an yearly basis, a Training Cycle on the use of its power systems operation and expansion planning software. Engineers from all regions of the country have the opportunity to attend courses taught by experienced instructors.Customized in-company training programs, using real-world cases of the contracting company's day-to-day are also available.
