AIM: To enhance the transmission capability of transmission system by shunt and series
compensation using static controllers.
OBJECTIVES:
i. To understand the concept of flexible AC transmission and the associated problems.
ii. To review the static devices for series and shunt control.
iii. To study the operation of controllers for enhancing the transmission capability.
UNIT I INTRODUCTION 9
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 9
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 9
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 9
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 9
FACTs Controller interactions – SVC–SVC interaction - co-ordination of multiple controllers using
linear control techniques – Quantitative treatment of control
coordination.
