AIM: To enhance the transmission capability of transmission system by shunt and
series compensation using static controllers.
OBJECTIVES:
To understand the concept of flexible AC transmission and the associated problems.
To review the static devices for series and shunt control.
To study the operation of controllers for enhancing the transmission capability.
UNIT I INTRODUCTION
The concept of flexible AC transmission - reactive power control in electrical power
transmission lines -uncompensated transmission line – series and shunt compensation.
Overview of FACTS devices - Static Var Compensator (SVC) – Thyristor Switched
Series capacitor (TCSC) – Unified Power Flow controller (UPFC) - Integrated Power
Flow Controller (IPFC).
UNIT II STATIC VAR COMPENSATOR (SVC) AND APPLICATIONS
Voltage control by SVC – advantages of slope in dynamic characteristics – influence of
SVC on system voltage. Applications - enhancement of transient stability – steady state
power transfer – enhancement of power system damping – prevention of voltage
instability.
UNIT III THYRISTOR CONTROLLED SERIES CAPACITOR(TCSC)AND
APPLICATIONS
Operation of the TCSC - different modes of operation – modeling of TCSC – variable
reactance model – modeling for stability studies. Applications - improvement of the
system stability limit – enhancement of system damping – voltage collapse prevention.
UNIT IV EMERGING FACTS CONTROLLERS
Static Synchronous Compensator (STATCOM) – operating principle – V-I characteristics
– Unified Power Flow Controller (UPFC) – Principle of operation - modes of operation –
applications – modeling of UPFC for power flow studies.
UNIT V CO-ORDINATION OF FACTS CONTROLLERS
FACTs Controller interactions – SVC–SVC interaction - co-ordination of multiple
controllers using linear control techniques – Quantitative treatment of control
coordination.
