The given graph is the depiction of ________ on a large power system network.
: b Explanation: A LG fault will create a sudden dip in the voltage profile and it will be recovered.
: b

recovered.
A 50 bus power system Ybus has 80% sparsity. The total number of transmission lines will be ___________
a Explanation: Number of non zero elements = 50*50*20/100 = 500 non zero Number of TL = (500-50)/2 = 225 transmission lines
a
See lessExplanation: Number of non zero elements = 50*50*20/100 = 500 non zero
Number of TL = (500-50)/2 = 225 transmission lines
A 200 bus power system has 160 PQ bus. For achieving a load flow solution by N-R in polar coordinates, the minimum number of simultaneous equation to be solved is ___________
a Explanation: Total buses = 200 PQ buses = 160 PV buses = 200-160 = 40 Slack bus = 1 Total number of equation = (40-1)*1 + (160*2) = 359.
a
See lessExplanation: Total buses = 200
PQ buses = 160
PV buses = 200-160 = 40
Slack bus = 1
Total number of equation = (40-1)*1 + (160*2) = 359.
For a given power system, its zero and maximum regulation will occur at the impedance angle of
a Explanation: At θ=45°, ZVR and maximum VR coincide.

A power system will have greater flexibility of operation if they have ________
: b Explanation: If various types of power plants are operated in combination, the system will become more flexible i.e Steam and Nuclear power plants will supply base loads, Hydroelectric power plants will supply base or peak loads depending upon the availability of water, Gas turbine power plant wRead more
: b
See lessExplanation: If various types of power plants are operated in combination, the system
will become more flexible i.e Steam and Nuclear power plants will supply base loads,
Hydroelectric power plants will supply base or peak loads depending upon the
availability of water, Gas turbine power plant will meet peak load demand and existing
Diesel power plant will operate in emergency only.
