IMPROVING METHODS FOR EVALUATION OF TRANSFORMER'S RESERVE POWER FOR TECHNOLOGICAL CONNECTION OF CONSUMERS
The paper describes improving methods for evaluation of transformer's reserve power on traction and transformer substations of Russian Railways. The necessity to adjust the current methodology according to the changes of the regulatory framework is justified. Two variants for calculating the current load is presented: on the basis of test measurements and with calculation method on the basis of consumers' contract demand. The formula calculating possible growth of electric load is presented. The proposed method can be used when concluding contracts for technological connection and formation of power supply network investment programs of “Russian Railways” joint stock company.
