Using software tools consolidated in the market (DIGSILENT POWER FACTORY, CEPEL ANATEM, REIVAX SEC, among others), electromechanical stability studies are developed for different types of power plants (hydroelectric, photovoltaic, wind power, thermoelectric) considering controllers and machines from different manufacturers.
The validation of the mathematical models against the curves obtained from field tests is carried out following the determinations of the Brazilian System Operator (ONS standard report).
The tuning of control loops for Digital Hydro Governors, Voltage Regulators and Power System Stabilizers can be simulated prior to commissioning new equipment, both in retrofits and new power plants.
REIVAX’s vast experience allows its professionals to work in the maintenance, commissioning, and adjustment of controllers.
The services are provided in new and legacy REIVAX equipment, or even controllers from other manufacturers.
Plant modernization processes may demand technical support in the electrical and mechanical areas, in the specification of new equipment, instrument replacement, equipment and cable testing.
Plant digitization processes create major challenges both in technical issues, linked to equipment specification, as well as in human resource optimization.
REIVAX has a highly qualified team to work both in the factory and in the field. It has more than 30 years’ experience with the development, design, manufacturing and commissioning of control, protection and automation systems.
Count on REIVAX’s Technical Support.
In power system planning and expansion studies, suitable models of the controllers (Combined Excitation System and Speed Governor s) and the generating units (generators and turbines) are required.
Such models, provided by the manufacturers, require validation with field tests, in order to confirm that the model properly represents the physical system.
Standardized controller models can be used in the studies, with the parameters being validated through field tests. However, it’s possible to survey the controller transfer feature that doesn’t fit the standard models. After field tests are performed, the curves obtained are compared with the simulated curves.
REIVAX has more than 30 years’ experience in the modeling of machines and controllers. The block diagrams can be delivered in different data files, according to the tool used: CEPEL ANATEM, DIGSILENT POWER FACTORY, SIEMENS PSS-E, ENGIE EUROSTAG, MATLAB, among others.
REIVAX’s vast experience in the development, design, manufacturing, and commissioning of control, protection, and automation systems puts the company’s professionals at a level capable of delivering high-level technical training.
During REIVAX’s training, the different electric sector’s stakeholders, linked to the Project, Construction, Operation, Maintenance, among others, will receive theoretical and practical information, helping them perform their activities.
Courses in the in-person at the client’s headquarters, in-person at REIVAX, or distance learning (Online) modalities allow clients to be trained as conveniently as possible.
Complete courses or even mini-courses allow the discussion of relevant topics during new power plant or retrofit projects. Different countries have already hosted REIVAX Technical Seminars, discussing topics of interest: Chile (2015 and 2017), Peru (2015 and 2017), Costa Rica (2016), Colombia (2017), Mexico (2018), Argentina (2018), as well as different clients in Brazil (CTG Brazil, Neoenergia, Elera, Furnas, Aliança Energia, CHESF, CELESC, COPREL, ENEL, ELETRONUCLEAR, PETROBRAS, CEMIG, ATIAIA, LIGHT), among others.
