| Abstract: | With the constant expansion of scale for electric networks in Baotou Steel,there are some new characteristics for power supply system so that the traditional relay protection has been very difficult to satisfy new demands.In the paper,the principles,adjusting methods and applications of directional longitudinal protection for short lines are elaborated by taking the protection allocation of 10 kV lines in 78# transformer substation in northern electric networks of Baotou Steel as example as well as the advantages and disadvantages are discussed. |
