110kV Substation Design And Implementation

With the development of society, technology and economy, more and more complex and powerful, the grid design and power equipment selection requirements are also more and more high. 110kV substation is an important area of substation, power distribution network development is the current focus of power grid development situation in the most important a ring, so the combination of distribution network planning guidelines for China State Grid Corp and local distribution network actual situation of grid research and realize the 110kVt substation design, not only has a certain practical significance, but also has a certain standard value and application significance.This paper first reviews the development status at home and abroad 110kV transformer substation design field, based on summing up the development results, according to the actual requirements, puts forward the design goal of this substation.Secondly, the system introduces 110kV conventional substation electrical design, device of primary equipment, electrical 110kV substation integrated automation system, the monitoring function, relay protection, substation main control and AC / DC system and other related equipment has done a detailed analysis and research;Again through the short-circuit current, load current calculation, verification of the theoretical basis of the design of the substation;Finally, through the example of application, combined with the design and implementation of local distribution network planning -- 110KV Xiang gang changed, and through the calculation, the setting of key parameters of substation circuit breaker, isolating switch equipment..
