This document discusses constraints and load flow analysis in power systems. It outlines four key constraints: active power constraint, reactive power constraint, voltage magnitude constraint, and load angle constraint. It also describes load flow analysis as a balanced mechanism between demand and generation under incremental loading. Load flow analysis is important for the safe and future operation of power systems. The document further discusses bus classification, basic power flow conditions including the proportional relationships between reactive power and voltage and active power and load angle. It also covers the development of the Y-bus matrix considering line resistances and inductances alone and then including line capacitances.

- 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. THANKS……
