In the article, we provided to factory earnestly the raw data is analyzed. First operation of electric power load, according to the requirements of the low voltage power factor in busbar side of the reactive power compensation, then the main transformer and the workshop transformer in choice. At the same time for aerial were chosen and calibration. In the article, we to 35 KV and six KV short-circuited the bus place when short-circuit current calculation, got the biggest operation mode and minimum running under the way of short-circuit current. According to our factory to the requirements of the relay protection, relay protection device of setting calculation.
