Analysis of the quality of the energy service (ACSE)
Evaluation of the quality of the electrical energy influenced by the harmonic content of current and voltage, voltage variations
and flicker rates, depressions or sags, swells, voltage and current imbalances, etc. by the connection
of high-capacity non-linear loads, such as fluctuating loads (electric arc furnaces, continuous arc welding machines,
continuous saws, etc.), impulsive and intermittent loads (induction motors, large cranes, punching machines, etc.).
distorting loads (induction furnaces, electrolytic tanks, large frequency variators, etc.) and the interconnection
of power plants of renewable, fluctuating, intermittent and distributed generation.
AEE - Analysis in stable state
Calculation of the operating conditions of the behavior of the national electrical system
(SEN - "Sistema Eléctrico Nacional") in
the generation of active and reactive power, active and reactive power flows in the electrical network,
angular openings, voltage profiles, etc., with all the elements of the electrical network in service
with application of n-1 contingencies for different generation dispatches to identify overloads and
reliability risks.
ET - Transient stability analysis
It will understand the behavior of the electrical system, by the integration of the power station or
the load center under study, to verify the angular and voltage behavior in the first oscillation,
interactions of protection schemes with power oscillations, dynamic deviations of the frequency,
damping of oscillations and in general the stability level of the
SEN.
CE - Coordination of schemes
CENACE carries out the necessary studies to determine the adjustments that are required for
the correct coordination of the Remedial Action Schemes (EAR - "Esquemas de Acción Remedial")
and System Protection Scheme (EPS - "Esquema de Protección de Sistema")
that are implemented and could be affected by the interconnection effect of a power station or
before the connection of a load center.
ACE - Analysis of the quality of energy
Quality Analysis of the Energy Service (ACSE - "Análisis de la Calidad del Servicio de Energía"):
Evaluation of the quality of the electric power
influenced by the harmonic content of current and voltage, voltage variations and flicker rates,
depressions or sags, overvoltages ( swells), voltage and current imbalances, etc.,
by the connection of high-capacity non-linear loads, such as fluctuating loads
(electric arc furnaces, continuous arc welding machines, continuous saws, etc.), impulsive and
intermittent loads (motors of induction, large cranes, punching machines, etc.).
distorting loads (induction furnaces, electrolytic tanks, large frequency variators, etc.) and
the interconnection of power plants of renewable, fluctuating, intermittent and distributed generation.
