Problem9AGCVsMVA[LOSSES]
Scope:
In this problem I attempted to find a relationship between Losses [MVA] and number of
generators on AGC.
Simulation:
For this problem, I used p9c1.pwd and p9c1.pwb which has all the AGC and AVR
unchecked for all nine genera

Problem 8: Voltage Regulation
Introduction
A local voltage collapse can and does lead to a widespread collapse of the power system. In this problem, I will
try to find different ways of voltage regulation and verify their effectiveness: shunt capacitor b

Automatic Generation Control
Introduction
Automatic Generation Control, known as AGC, in power system is the process of matching the
changing load demand with the power produced by all the generating units attached to the
network. In this set of problems,

Example: Plant load of 1200 hp @ 2200V is supplied with: (1) 600hp synchronous motor at
0.85 power factor leading and 85% efficiency and (2) 600 hp induction motor at 0.9 power factor
and 95 efficiency. Determine the line current necessary to supply this

PF Problem from Class
Example
Two loads are connected in parallel. The first load is rated at 100 kW and load at a power factor
of 0.8. Another load of 15kW and 30 kVAR is connected in parallel as shown in the figure below.
Calculate
i. pf, P, Q, and S an

Example
The total power it produced by the load is 60 horse power and the efficiency is 95%. The
apparent power is 50 kVA and the voltage is 440V. To change the pf to 0.8 find the value of
inductor we have added in this system.
Solution:
1 horse power =0.
