MATLAB: I want to model 100KVA load operating at 0.9 power factor lagging. What should i set Active Power, QL and QC in load parameters

Question

Hi,

Please help me find the answer to this question:

I want to model 100KVA load operating at 0.9 power factor lagging. What should i set Active Power, QL and QC in load parameters?

Answer 1

Dear Syed Umaid Ali,

as per your requirement

Apparent power S= √(P^2+Q^2 ).....................................(1)

And power factor Cosφ= 0.9 lagging, i.e. only inductive load(QL=.. and Qc=0);

Where ϕ= tan^-1(Q/P),.....................................................(2)

from Eq. 1 and 2 you can obtained value of P and QL
