• What is Electric Network

(6)

Substation is a node in the grid electric network

Substation is linked to one voltage level

1. Dispatch power flow on

branch/lines

2. Allow maintenance

(line/device)

3. Select/eliminate fault in

only one section

4. Mesh network (stability)

• Primary Device: Bus Bar

Feeder => interface to Voltage level (line branch, transformer)

Bus Bar => Backbone to dispatch power between feeders

(10)

• Primary Device: Circuit Breaker

Make / Break Current then Power flow

Operate under Nominal or Faulty condition

- exploitation

(11)

• Primary Device: Bar / Line Isolator

Bar Isolator : Isolate CB / Bar (maintenance/exploitation)

Line Isolator : Isolate CB / Line (line maintenance)

• Why measurement CT/VT

CT/VT : Lower Primary Values (HV) to Secondary Values (LV)

• Galvanic Isolation (no current between HV / LV)

Substation

• Site Partition => Local/Remote substation

• Substation Control Uniqueness

• (nb=1) The Business DB (except Cascade)

Voltage Level

• Association of Bus Bars for Auto Volt. Regul.

• Often only one BB (nb 4-5-x)

Bay

• ANSI => 1 CB with associate circuits & protections

• Association of switchgears/transformers & functions

• Local/Remote Bay, SBMC, Bay Control Uniqueness

• Special (coupler, section, feeder, transformer)

• Often Generic (more easy)

• Bay belongs to only one C264

Module

• Primary Electric Device, ANSI functions, Group of DP

• Special (CB, disconnector, transformer, AR, Sync)

• Often Generic (DPS/DPC association possible)

Datapoint

• Real Time information (95% electric)

• At any level

Control

=> dispatch energy

=> keep service (continuity, quality)

=> maintenance operation

Protection => Fault (Shortcut)

• 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
