Second, how much is the capacity of the 110KV transformer?

The 110kV transformer means that the rated voltage of the inverter is 110kV.

The transformer capacity in kVA is another concept and is not necessarily related to the rated voltage.

However, the capacity of a 110kV transformer is generally not too small. The capacity of a common 110kV power transformer is: 6300kVA, 8000kVA,10000kVA, 12500kVA, 16000kVA,20000kVA, 25000kVA, 31500kVA,40000kVA, 50000kVA, 63000kVA, etc.

Third, the capacity calculation of the main transformer of 110kv substation

According to the maximum load selection, the substation selects double main transformers. Each main transformer can run separately to meet the first-stage one-stage load power supply. If there is no primary load ratio, generally every main transformer must meet 80% of the maximum load. Above, the total load is about 27mw, (here is estimated) with two SFS9-31500/110 main can meet the two outgoing and spare through the transformer, but calculate the power of the incoming line to select the model of the overhead line To.
