Abstract:
The Static VAR Compensator provides reactive power and voltage
support to the transmission system by switching local SVC capacitors and
controlled reactor. The SVCs are needed the most during network
disturbances. At these occasions they may make the difference between a
network collapse and successful continued operation, The basic task of the
SVC fault clearance system is to detect a specified class of power system
faults and abnormalities and to disconnect the associated item of plant from
the rest of the power system, The fault clearance system shall perform with
high reliability, speed, selectivity and sensitivity.
This thesis will focus on the control based over/under-current and
thermal overload protection for the SVC and also on the relay-based
protection included in the SVC installation will also be discussed.
The simulation will focus on applying different types of faults which
may accrue in LOCALMARKET SVC substation and how they can be
detected and cleared by the protection system of the SVC. The analysis is
carried out using MATLAB SIMULINK software.
