POWER SYSTEM OPERATION AND CONTROL
Objective :
This subject deals with Economic operation of Power Systems, Hydrothermal schedulings and modeling of
turbines, generators and automatic controllers. It emphasizes on single area and two area load frequency
control and reactive power control.
UNIT – I Economic Operation of Power Systems-1
Optimal operation of Generators in Thermal Power Stations, – heat rate Curve – Cost Curve – Incremental
fuel and Production costs, input-output characteristics, Optimum generation allocation with line losses
neglected.
UNIT – IIEconomic Operation of Power Systems-2
Optimum generation allocation including the effect of transmission line losses – Loss Coefficients, General
transmission line loss formula.
UNIT – III Hydrothermal Scheduling
Optimal scheduling of Hydrothermal System: Hydroelectric power plant models, Scheduling problems-
Short term Hydrothermal scheduling problem.
UNIT –IV Modelling of Turbine, Generator and Automatic Controllers
Modelling of Turbine: First order Turbine model, Block Diagram representation of Steam Turbines and
Approximate Linear Models.
Modelling of Generator (Steady State and Transient Models): Description of Simplified Network Model of a
Synchronous Machine (Classical Model), Description of Swing Equation (No Derivation) and State-Space
II-Order Mathematical Model of Synchronous Machine.
Modelling of Governor: Mathematical Modelling of Speed Governing System – Derivation of small signal
transfer function.
Modelling of Excitation System: Fundamental Characteristics of an Excitation system, Ttransfer function,
Block Diagram Representation of IEEE Type-1 Model
UNIT – V Single Area Load Frequency Control
Necessity of keeping frequency constant.
Definitions of Control area – Single area control – Block diagram representation of an isolated power
system – Steady state analysis – Dynamic response – Uncontrolled case.
UNIT – VI Two-Area Load Frequency Control
Load frequency control of 2-area system – uncontrolled case and controlled case, tie-line bias control
UNIT-VII Load Frequency Controllers
Proportional plus Integral control of single area and its block diagram representation, steady state
response – Load Frequency Control and Economic dispatch control.
UNIT – VIII Reactive Power Control
Overview of Reactive Power control – Reactive Power compensation in transmission systems –
advantages and disadvantages of different types of compensating equipment for transmission systems;
load compensation – Specifications of load compensator, Uncompensated and compensated transmission
lines: shunt and Series Compensation.
