Introduction Load flow study play a key role in the planning of
additions or expansions to transmission and generation facilities
A load flow solution is often the starting point for many other types of power system analysis
Load flow analysis at the heart of contingency analysis and the implementation of real time monitoring systems
Load flow analysis is the study of the behavior of power system
It determines if system voltages remain with in limits under normal or emergency operating conditions
Whether equipments like transformers and conductors are overloaded
We can get some practical profile of bus voltage
We can identify real and reactive power flow and minimize KW and KVAR losses
It is important to grow and expand our system
Our project is based on ETAP 6.0 software
Problem Statement FDR-ANA does not have capability to provide comprehensive
analysis
The main cause of disturbance in power system is under voltage
Future up gradation of power system network
The voltage at each bus should be known for losses calculation
Assessment of power system:• within operational limits • system is safe
Objectives To monitor and analyze the power system
accurately
To overcome the under voltage problem
To expand the substation in future demand
To improve the power factor of power system
To minimize the losses of power system
Methodology We have collected data of 132kv GSS Cantt Peshawar.
Then we simulate single line diagram in ETAP 6.0 .
After load flow analysis of single line diagram we have seen that all the feeders were operating under voltage.
Also there were more losses on each bus.
we connected suitable devices like Distributed Generator and again simulated.
To overcome the problem we connected DG with each feeder one by one.
When we simulated the single line diagram with DG connected to each bus then concluded that the under voltage problem and losses were improved.
