Power System Studies refers to the study of power evacuation from generation to
loads, under control, protection and supervision; and under normal or
contingency conditions; under various expected operation scenarios;
capturing the behaviour of the electrical network, its elements,
its control, protection and their response under different time
frames, spanning few a micro seconds to several hours or even years of time.
These studies may also be classified as Static, Dynamic or
Transient, depending on the mathematical models used in analysis
and the time frame of examination of the behavior of the power system under
consideration.
The nature of the studies and their objectives may vary for different types of
electrical network [or power systems] and the problems being analyzed, with
possible different criteria. Thus a study for a transmission system , a
distribution system or an Industrial network may not all have identical
perspective, even though the type of analysis modules used in analyzing them are
same.
These studies may fulfil the objectives of system planning, system
design, system protection and control, developing system operation strategies,
commercial and technical evaluation and feasibility studies, solutions for
problems faced during system operation.
These studies are pre-requisites for any new system, for any new
renovation, modernization and expansion plans, and also for existing systems for
arriving at solution for problems faced in the operation.
As a rule, it is mandatory to perform the power system studies, where
interconnection of two different systems are proposed. For example,
interconnection of a industrial load to a distribution company, requires that
standard set of studies to be performed, typically covering, the load flow,
short circuit, relay coordination, harmonic analysis , motor startig studies and
stability studies as applicable.
List of Power System Studies/Analysis
The
power system study group have performed widest
possible range of power system studies as
follows. The studies cover planning, engineering,
economic aspects of power
system, design, operation, control and protection
and uses appropriate static, dynamic or transient study models for
power systems.
