This design is the basic principle of the relay protection, on the basis of the
given by 35 kv step-down substation load case and a part of the analysis, and
combining with reliability, economy, and make analysis for the substation relay
protection initial configuration and setting. In the design process, through the
substation a part of the structure, load condition and the short-circuit point
in the short circuit of short circuit current and so on analysis and
calculation, and finally determine the substation relay protection configuration
and setting value of the size. In the design of the main protection: transformer
longitudinal differential protection, the gas protection, load voltage start
over current protection, overload protection, 10 kv line of instantaneous
electric velocity fault protection and time limit current instantaneous break,
etc. Through this graation design, I deepened to the understanding of the
previous knowledge, improve their ability of practice.
