Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuSUNIT I PRELIMINARIES ON POWER SYSTEM OPERATION AND
CONTROL
Power scenario in Indian grid – National and Regional load dispatching centers –
requirements of good power system - necessity of voltage and frequency regulation - real
power vs frequency and reactive power vs voltage control loops - system load variation, load
curves and basic concepts of load dispatching - load forecasting - Basics of speed
governing mechanisms and modeling - speed load characteristics - regulation of two
generators in parallel.
UNIT II REAL POWER - FREQUENCY CONTROL
Load Frequency Control (LFC) of single area system-static and dynamic analysis of
uncontrolled and controlled cases - LFC of two area system - tie line modeling - block
diagram representation of two area system - static and dynamic analysis - tie line with
frequency bias control – state variability model - integration of economic dispatch control
with LFC.
UNIT III REACTIVE POWER – VOLTAGE CONTROL
Generation and absorption of reactive power - basics of reactive power control – Automatic
Voltage Regulator (AVR) – brushless AC excitation system – block diagram representation
of AVR loop - static and dynamic analysis – stability compensation – voltage drop in
transmission line - methods of reactive power injection - tap changing transformer, SVC
(TCR + TSC) and STATCOM for voltage control.
UNIT IV ECONOMIC OPERATION OF POWER SYSTEM
Statement of economic dispatch problem - input and output characteristics of thermal plant -
incremental cost curve - optimal operation of thermal units without and with transmission
losses (no derivation of transmission loss coefficients) - base point and participation factors
method - statement of unit commitment (UC) problem - constraints on UC problem - solution
of UC problem using priority list – special aspects of short term and long term hydrothermal
problems.
UNIT V COMPUTER CONTROL OF POWER SYSTEMS
Need of computer control of power systems-concept of energy control centers and functions – PMU - system monitoring, data acquisition and controls - System hardware configurations
- SCADA and EMS functions - state estimation problem – measurements and errors - weighted least square estimation - various operating states - state transition diagram.
