Research on Key Technologies for Substation Renovation and Manufacturing Methods of Simulated Circuit Breakers
This paper takes a 35 kV/10 kV substation as the analysis object.Through the use of temporary load transfer,small current grounding device fault line selection method,current transformer polarity verification,single-phase grounding fault line selection algorithm,main transformer direction blocking protection,and distance verification method,the shortcomings in traditional substation operation are ultimately improved.The final conclusion drawn from the research is that temporary switching stations can be used in load transfer in substations,and fault line selection analysis can use fault current limiting harmonic algorithm or fault current fundamental wave line selection algorithm.
