at a cost of 500 MUPB. 100% loan has been used for the financing of
this transformer center. The maturity is 10 years and the loan
interest is 15% and the repayments will be in equal installments.
130 MVA power was drawn from the substation in 2010 and the power
demand growth rate in the region is 11.6%/year and. In the year
when the power demand reached 90% of the installed capacity, the
second 250 MVA identical transformer center was commissioned. Based
on 2010, the escalation rate of domestic materials used in the
transformer center is 25%/year and the escalation rate of imported
materials is 40%/year. The share of imported materials in the
construction of the transformer substation is always 30%. 100%
credit was used for the financing of the new transformer station:
The maturity is 10 years and the loan interest is 21%/year, and the
repayments will be in equal installments. (a) Find the ratio of
"debt installment paid (MUPB)/power drawn by load (MVA)" for 2018.
(b) Find the ratio of "annual depreciation (MUPB)/current draw
(ampere) of the load for 2018. (When both transformers are in
circuit, the 3-phase short-circuit current lk calculated in the
load busbar" = -j148.2 kA and the load The short-circuit impedance
seen from the busbar is Zk = j1.8 phm/phase.The voltage coefficient
in the calculation of the short-circuit current is taken as 1.1, in
accordance with the 1EC 60909 Standard.) (The scrap value is taken
as zero for transformer substations, the economic life is accepted
as 25 years and "normal" (linear) depreciation method" is
used.)
