A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control.

Role of substations in an electrical network, types and configurations of substations

  • Networks – an introduction
  • Different voltages in a network
  • Substations as network nodes
  • Substation types based on their position in the network
  • Optimising the location of a substation
  • Substation options: Outdoor air insulated, GIS, Indoor air insulated

Recording 2

System studies required for finalising equipment ratings

  • Load flow study (active/reactive loads)
  • Short circuit study
  • Harmonic flow
  • Voltage profile and reactive power compensation
