Research on Primary System Design of 110 kV Intelligent Substation Based on Electrical Calculation——Taking an Electric Power Equipment Manufacturing Enterprise as an Example
The primary system design of 110 kV intelligent substation includes the selection of electrical equipment,lightning protection and grounding method and resistance,reactive power compensation,short circuit current,etc.In order to ensure the performance of the substation and reduce the cost of the project,the research process applies the electrical calculation method and analyses a variety of design parameters at the theoretical level,covering reactive power compensation capacity,capacitor resonance,transformer capacity,the maximum operating current of each circuit,grounding resistance,cross-section area,and grounding resistance,which provide a good basis for the primary system design and the design of the substation.cross-sectional area,grounding resistance,and provides a quantitative basis for the selection of equipment,cables,busbars,distribution devices,and grounding wires in the primary system.
