I’m, now working with multinational company , name = AREVA T&D
This small description is to tell u about my work,
First AREVA T&D Middle East is handling big projects in all Middle East and North Africa, projects for transmission and distribution of the electrical Energy, the highest voltage level handled till now is 400KV.
To build substations different contractors should interfere for Civil, Mechanical, and Electrical work [basic electrical materials are GIS [HV breaker], Line and Bus Isolators, Earth switches…].
And of course to build such stations u need automation inside and here come our turn.
AREVA T&D automation is the HITECH office of AREVA T&D that is responsible of all Protection, monitoring and control work of substations.
When the substation is Build and the SLD[Single line diagram] is in our hand we will start first by the protection work this is a separate department in my company called CCS, So in every feeder [Incomer , outgoing , bus section , bus coupler …] we need to put some number of numerical relays called protection relays that insure complete protection of the feeder , many kind of protection relays are used [Over voltage , over current under frequency , distance protection , differential protection…].
After protecting the substation the second phase is the DCS [Digital control system] or SCS [substation control system] , I’m working in this department , DCS is Doing a big system architecture based on Ethernet network that connect many BCU [Bay control unit = DSP ] by fiber optic Dual ring , so for every feeder we put one BCU that take all information from protection relays[alarms , trip, status] by Modbus or 103 protocol and also those BCUs can control all Electrical part in substations[Breaker , isolator, earth swith…] and those BCUs also are responsible of the automation of the feeder[Interlocking , autorecloser , synchrochock].
All info collected by BCUs [inputs , outputs…] are shared in a common ring that contain also 2 PC.
First PC is the server for a LAN based on server client protocol , so all info collected by server from all BCUs are viewed in a good way on the Clients PCs[ graphic representation of all the substation with animation called HMI], from the clients we can issue control , and monitor all the substation[alarms…]
Second PC is a gateway to give and take info from a remote workstation [we called this workstation Scada] so the gateway will translate between Fast Ethernet and 101 and 103 protocol and also in this remote workstation we can monitor , and issue control into the substation.
The final part of Substation automation is the energy management and this is a separate part in my company and this part is responsible of controlling and monitoring many substations in a whole country or number of countries…
I’m now handling a project as DCS Application Engineer, name = NDIA [New Doha international airport] this project contain 5 substations that feed the airport, the voltage level is 66kv and 11kv. Our DCS team contain 5 site engineers and those eng have done the programming as well as the site commissioning and I’m responsible of them and responsible of the global design of the project .
I forgot to mention that our DCS software and hardware system is called PACIS.
I like this scope of work because it contain Power engineering, control Engineering and network Engineering and I have took the basic info in control industrielle in ULFG1.
