• What is Electric Network
Electric Network is a Hierarchy of Voltage

Transmission Transport 600-400kV

Repartition 220kV

kV 400

225 kV

Bi-directional Mesh

Distribution

90 kV

Distribution 110-90 kV Directional Antenna

Delivery 2-6-20kV Antenna / Annealing

Schneider Electric - CS&P – System Terminology – E01

6-20 kV

4

• What is Electric Network
Carry Electricity from Producers to Consumers

Producer Industrial Consumer Schneider Electric - CS&P – System Terminology – E01

Domestic Consumer 5

• What is Substation
Substation is a node in the grid electric network
Substation is linked to one voltage level

Schneider Electric - CS&P – System Terminology – E01

1.

Dispatch power flow on branch/lines

2.

Allow maintenance (line/device)

3.

Select/eliminate fault in only one section

4.

• Primary Device: Bus Bar
Feeder => interface to Voltage level (line branch, transformer)
Bus Bar => Backbone to dispatch power between feeders

Schneider Electric - CS&P – System Terminology – E01

• Primary Device: Circuit Breaker
Make / Break Current then Power flow
Operate under Nominal or Faulty condition

Schneider Electric - CS&P – System Terminology – E01

- exploitation - shortcut current

10

• Primary Device: Bar / Line Isolator
Bar Isolator : Isolate CB / Bar (maintenance/exploitation)
Line Isolator : Isolate CB / Line (line maintenance)

Schneider Electric - CS&P – System Terminology – E01

• Measurement Transformer CT/VT
Provide current / voltage measurement to Protection/Control System

Schneider Electric - CS&P – System Terminology – E01

15

• Why measurement CT/VT
CT/VT : Lower Primary Values (HV) to Secondary Values (LV) • Galvanic Isolation (no current between HV / LV) • Measurement Reduction

• Why protecting
Control

=> dispatch energy => keep service => maintenance operation
Protection => Fault (Shortcut)

• • • •

(continuity, quality)

Short circuit implies unbalancing, voltage drop… Isolate Faulty section Save device from destruction Secure installation fire / explosion (arc) people security (insulation)


Protection => Exploitation (Overload)

• Unbalanced exploitation • Damaging isolation • Degrading devices
