power system modeling software is the clinical approach to power distribution from the view point of:

a) system safety

b) system reliability

c) maximum availability

the above are directly related to productivity and safety of humans and property

software based power system simulation is

i) free from human errors (in calculations)

ii) results are reliable (provided input data is proper and complete)

iii) report presentation and documentation is up to mark and in compliance with international standards

the recommended studies for power distribution are

a) load flow analysis

b) short circuit calculations

c) arc flash analysis

d) harmonic modeling

e) protective relay coordination

deliverables of the above recommended studies

load flow study à steady state stability issues if any get highlighted. Adequacy of ratings of cables get established.

power losses in the system for typical loading get

worked out.

short circuit calculations àadequacy of breaker ratings in the power distribution

arc flash analysis à deals with safety as per international (ieee1584) norms. Works out ppe as per hazard category based on calculated incident energy due to arc currents during flash over conditions.

harmonic modeling à  based on captured data, the entered values of existing harmonics at buses having nonlinear loads suitability of filtering solutions can be ensured through simulations prior to implementations.

protective relay coordination à  existing settings of protective relays and releases with the breakers on ht and lt levels can be cross verified for proper tripping such that wanted breaker in the power distribution only trips (avoiding random / inappropriate tripping) to eliminate possibilities of major unwarranted black outs.

it can be visualized that basic overall health check of existing power distribution is possible in an accurate manner to ensure safety and relaibility of power distribution – using software based power system simulation.
