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.
