EE2401-POWER SYSTEM OPERATION AND CONTROL-ANNA UNIVERSITY SYLLABUS EEE





EE2401                      POWER SYSTEM OPERATION AND CONTROL                               L T P C
3  0 0 3
AIM:
To understand the day to day operation of power system and the control actions to be implemented on the system to meet the minute-to-minute variation of system load demand.

OBJECTIVES:
i.
To have an overview of power system operation and control.

ii.
To model power-frequency dynamics and to design power-frequency controller.

iii.
To model reactive power-voltage interaction and the control actions to be      implemented
for
maintaining the voltage profile against varying system load.

UNIT I             INTRODUCTION                                                                                                          9
System load variation - load characteristics - load curves and load-duration       curve            (daily, weekly and annual) - load factor - diversity factor. Importance of    load    forecasting    and    simple techniques of forecasting. An overview of power     system  operation  and  control  and  the  role  of computers in the implementation.     (Qualitative treatment with block diagram).

UNIT II            REAL POWER - FREQUENCY CONTROL                                                                9
Basics of speed governing mechanism and modeling - speed-load characteristics load sharing between two synchronous machines in parallel. Control area concept       LFC  control  of  a  single- area system. Static and dynamic analysis of uncontrolle an controlle cases.   Integratio of economic dispatch control with LFC. Two-area system modeling - static analysis of uncontrolled case - tie line with      frequency bias control of two-area system - state variable model.

UNIT III           REACTIVE POWERVOLTAGE CONTROL                                                               9
Basics of reactive power control. Excitation systems modeling. Static and          dynamic analysis - stability compensation - generation and absorption of reactive power. Relation between voltage, power and reactive power at a node - method of voltage control - tap-changing transformer. System
level control using generator voltage magnitude setting, tap setting of
OLTC
transformer    and
MVAR injection of switched capacitors to maintain  acceptabl voltage
profile
an t minimize
transmission loss.



UNIT IV          UNIT COMMITMENT AND ECONOMIC DISPATCH                                                  9
Statement of economic dispatch problem – cost of generation incremental cost curve co-ordination equations  without  loss  and  with  loss,  solutioby  direct  method  anλ-iteration  method.    (No derivation of loss coefficients). Statement of Unit Commitment problem – constraints; spinning reserve, thermal unit constraints, hydro constraints, fuel constraints and other constraints. Solution methods - Priority-list methods - forward dynamic programming approach.            Numerical
problems only in priority-list method using full-load average production cost.

UNIT V           COMPUTER CONTROL OF POWER SYSTEMS                                                       9
Need of computer control of power systems. Concept of energy control centre (or) load dispatch centre and the functions - system monitoring - data acquisition and control. System hardware configuration SCADA and EMS functions. Network topology - state estimation - security analysis and control. Various operating states (Normal, alert, emergency, in-extremis and restorative). State transition diagram showing various state transitions and control strategies.
