2. CONTENTS:
* CONSTRAINTS OF POWER SYSTEM
1.ACTIVE POWER CONSTRAINT
2.REACTIVE POWER CONSTRAINT
3.VOLTAGE MAGNITUDE CONSTRAINT
4.LOAD ANGLE CONSTRAINT
* LOAD FLOW ANALYSIS
1.BUS CLASSIFICATION
2.BASIC POWER FLOW CONDITIONS
3.DEVELOPMENT OF Y-BUS MATRIX

3. CONSTRAINTS:
CONSTRAINTS MEANS LIMITATIONS OR
BASIC OPERATING CONDITIONS IN
POWER SYSTEM
FOUR CONSTRAINTS ARE THERE.
1.ACTIVE POWER CONSTRAINT
2.REACTIVE POWER CONSTRAINT
3.VOLTAGE MAGNITUDE CONSTRAINT
4.LOAD ANGLE CONSTRAINT

5. LOAD FLOW ANALYSIS:
* IT IS A BALANCED MECHANISM
BETWEEN DEMAND AND GENERATION
UNDER INCREMENTAL LOADING
CONDITIONS
*AT PRESENT,, FOR SAFE OPERATION
OF THE SYSTEM AND IN FUTURE,, FOR
THE EXTENSION OF POWER SYSTEM

6. BASIC POWER FLOW CONDITIONS:
1.REACTIVE POWER IS PROPORTIONAL
TO BUSBAR VOLTAGE
2.ACTIVE POWER IS PROPORTIONAL
TO LOAD ANGLE

7. BUS CLASSIFICATION
(a) LOAD BUS (OR) P-Q BUS
(b) GENERATOR BUS (OR) P-V BUS
(c) SLACK BUS

9. DEVELOPMENT OF Y-BUS MATRIX:
HERE TWO CASE STUDIES ARE
CONSIDERED TO DEVELOP Y-BUS
MATRIX.
(1) BY CONSIDERATION OF LINE
RESISTANCE & INDUCTANCE ONLY
(2) CAPACITANCE TAKEN INTO
CONSIDERATION ALONGWITH
RESISTANCE & INDUCTANCE

10. CASE - 1:
CONSIDER THE DIAGRAM

11. CONSIDER THE FOLLOWING FIGURE

12. CASE - 2:
CAPACITANCE EXISTS IN SHUNT, DISTRIBUTED
ALONG THE LINE AS SHOWN IN THE FIGURE

14. THIS IS ALL ABOUT SYSTEM
MODELLING AND Y-BUS
MATRIX.
NOW I CONCLUDE HERE.
