Overall information:

•Works range and their time intensity

•Power outage planning and complications

Chosen accomplishments:

•Installation of smart meters at the CEZ Headquarters

•Installation of repeaters of the BPL technology

New solutions for installation of Smart Grids technology:

•Electrical distributor with a Smart Grids Module

•Distribution substation with a Smart Grids Module

Overall information

Within the WPP AMM project the AMM technology was installed in almost

1000 distribution substations

Furthermore was installed:

•over 100 couplers of the PLC MV technology;

•tens of repeaters of the BPL technology;

•and many others.

3-membered team → installation of AMM technology into one substation/day

Installation of the AMM technology includes:

•creation of interface in substation

•installation and start up of the AMM technology

Necessary power outage for installation → limitation of consumers

Power outage is necessary to plan at least 2 months in advance!!

Precise coordination → alpha and omega of AMM technology installations…

Coordination: what is connected with installation of AMM technology?„Decalogue of AMM“

Coordination of several outages and teams during one day:

1.Logistics of power outages…

2.Preparation for the day „D“ (material, possible complications etc.)

3.Verification of the right phase rotation before power outage

4.Acceptance of worksite by AZ Elektrostav before installation

5.Drawing of circuit diagram in Microstation in field

6.Creation of detailed photo documentation before and after installation

7.Functionality verification of the installed technology with the control

8.Acceptance of worksite by ČEZ Distribuční služby after installation

9.Issuance of works inspector‘s report

10.Preparation and signing of completion certificates and complete

documentation with ČEZ Měření and ČEZ Distribuce

Installation of smart meters at the CEZ Headquarters

„Able to measure – able to economize“:

• Installation of the AMM technology for power

circuits of each individual floor

• Measured data transmission and its display in

foyer → on-line consumption monitoring

Black-out simulation at the CEZ Headquarters:outcomes

CEZ News: CEZ Headquarters in Prague became best measured

office building in Central Europe…

Repeaters installation of the BPL technology

High-speed transmission→ high frequency → shorter range

Smart Region Vrchlabí:

• task to install about 30 repeaters in a plastic box

• indicated as routine installations → each box „4 screws and a

cord“

• drawn ambitious plan „2-membered team will install in 3 days“

i.e. 10 boxes a day…

Repeaters installation Ad hoc:

1. do we have project documentation ???

2. is settlement of property rights carried out ???

3. is power outage for installation planned???

• I will rather stop asking…

Repeaters installation of the BPL technology

1) Installation of box

with repeater

2) Repeater installation

on the door (outside)

3) Repeater installation

inside the stand

4) Repeater installation

on the cover

5) Repeater installation

on the door (inside)

Installations carried

out without outages!!i.e. without consumer limitations

Electrical distributor with a Smart Grids Module

Dimensions of Smart

Grids Module [mm]:

• 750x500

• 750x750

• 1000x500

• 1000x750

Out of 800 modules

only 7 modules were

greater than 1000x750

→ less than 1%
