Title Design for General 35 kv Voltage-reduction Substation
and High Voltage Distribution System in a
Manufacturing Co. LTD
Abstract
This topic of the design is "design for general 35 kv voltage-reduction
substation and high voltage distribution system in a manufacturing Co.
LTD". The design includes computational load and reactive power
compensation, the general voltage substation main wiring scheme,the
selection and validation of primary equipment according to the calculation
of short-circuit current, the outlet and inlet line of substation and the
choice of tie line check, setting of relay protection, substation lightning
protection and grounding design. A three electrical drawings of the design,
including general voltage substation main wiring diagram, general voltage
substation plan and arrangement plan of the grounding devices and high
voltage distribution system plane wiring diagram has been completed. All
the design is according to the relevant provisions of the national
electricity sector.
