3.2.1.2: QUALITY DATA FOR
SYSTEM
The data for the new SCADA/EMS system can be classified into
four main categories
1) Organizational Data
2) Reference Data
3) SCADA Process (Application) Data
4) EMS Process (Application) Data
3.2.1.2.1 Organizational Data
This is data for system organization. It includes
3.2.1.2.1.1 Transmission Network Plan
· One line diagram of the whole SIG showing all Zones,
Branches, Areas and Interconnections as well as all the hydro and thermal
generating stations, loads, busbars, switches (isolators, disconnectors and
circuit breakers), capacitor banks, transformers e.t.c
· One line diagram of all the existing transformation
substations and generating stations substations showing load centers, busbars,
switches (isolators, disconnectors and circuit breakers), capacitor banks,
transformers e.t.c
· Name; location; characteristic voltage levels; number
of feeders, transformers, capacitor banks, circuit breakers, isolators,
disconnectors, busbars and other major components of all transformation
substations and generating stations substations of the SIG
3.2.1.2.1.2 Telecommunication Network
Infrastructure
· Telecommunication Infrastructure Plan showing all the
different telecommunication networks (FO, GSM, VHF radio, PLC and microwave) on
the SIG used in association with this new SCADA system for data transfer as
well as for voice and data communication
3.2.1.2.1.3 Profile Data for System users (System
Operators and System Administrators)
Data defining all the logging parameters of system users
· Names
· User type: Normal system user, System operator or
System administrator
· Profile access method (knowledge-based e.g. password,
possession-based e.g. badge...)
· level of authorization such as Area Of Responsibility
(AOR), operation mode (read, write...), application access e.t.c
3.2.1.2.1.4 Generation System
Owner Data
Data from all generator/generation power station owners
concerning their generating facilities and would include
· power station owner e.g. KPDC
· power station owned e.g. Dibamba
· power station type e.g. Heavy Fuel Oil (HFO)
· available generation capacity in MW, MVA and MVar e.g.
86MW
· power station connection point, that is connection
substation e.g. Ngodi Bakoko substation
· power station location in terms of branch, zone, area,
town e.g. Douala, Littoral zone, Nyalla area e.tc
3.2.1.2.1.5 Transmission
System Customer/End User data
Data of the different transmission system customers (end
users) concerning their consumption facilities and would include
· Customer type (HV, MV or LV customer) e.g. MV
· Customer name e.g CIMENCAM
· Customer location (branch, zone, area, town) e.g.
Douala, Littoral zone, Bonaberi area e.t.c
· Connection point (substation) e.g Bonaberi
· Consumption in terms of MW, MVA and MVar e.g. 7MW
3.2.1.2.2 Referential Data
This is technical information of all network assets/equipments
both electrical, control and IT network assets. This information is very
important for maintenance (both predictive and corrective maintenance), system
operation (in performance and limitation check of systems and equipments) and
in asset inventory management.
3.2.1.2.2.1 Transmission System Electrical Network
Assets
This includes all up-to-date technical information obtained
from the manufacturers, nameplates and technical catalogues of all the
electrical network assets of the SIG concerning their technical
characteristics, makes and models, performance and limitations including
Ø Transformers
Ø Switches (reclosers, circuit breakers, disconnectors,
isolators, fuses)
Ø Transmission lines
Ø Capacitor banks
Ø Busbars
Ø Generators
Ø Protection devices
Ø Auxiliary equipments such as UPS, batteries,
rectifiers, battery chargers e.t.c
Ø Loads e.t.c
For example, referential data for a transmission line would
include
· Origin e.g. Logbaba
· Destination e.g. Bekoko
· Cable structure e.g. Almelec
· Dimension e.g. 570mm
· Length e.g. 41.50km
· Voltage e.g. 225Kv
· Transmission line capacity in MW, MVA and MVar
And for each transformer, information such as
· Location
· Manufacturer (make and model)
· Voltage level xtics
· Power
· Ohms
· Reactance
· Regulation
· % overload supported
· IP (protection index)
3.2.1.2.2.2 Telecommunication Network System
assets
Technical and performance data of all the telecommunication
and IT network assets including
Ø Fiber Optic cables
Ø Switches, routers, servers, monitors and RTUs
Ø GSM
Ø GPRS
Ø Radio
Ø Satellite
Ø Microwave
Ø Power Line Carrier
