FEEDER SEPARATION
SCHEME OF WEST DISCOM,
INDORE
GEOGRAPHICAL MAP OF WEST DISCOM
What is Feeder Separation
Erection of 11 kV additional bays with VCB and Laying of 11 kV
lines on 140 Kg 8 mtr long PCC poles with (rabbit) AAA
conductor.
Installation of 25 kVA 11/0.433 kV DTR and its metering
Replacement of bare conductor of LT lines by AB cables,
Conversion of LT line into HT line (HVDS), damaged service lines
by PVC cables & providing new connections with meters
Consumer indexing and its updation in billing software
 Asset mapping of HT & LT network using GPS
Certification of Distribution loss from Distribution transformer
to Consumer Premises
Present Situation of Power Supply in Villages
West Discom Indore provides power supply to 12029 Nos
villages. Agricultural pumps are normally provided 3 phase
supply for six to eight hours & in remaining hours either supply
is not available or 1 phase supply is being made available on
11 KV rural feeders so that pumps could not run but Domestic
light and fan and other load of village may get supply. This is
done by disconnecting one phase of the 11 KV supply. But this
arrangement is not fruitful & effective. Cultivators normally make
use of phase splitters to run their motors. This ultimately
increases the loading of feeders abnormally. This also causes
more failure of DTRs & PTRs besides interruptions. This results
in dissatisfaction among villagers. Purpose of load shedding/
regulatory plan gets defeated. The LT system is lengthy and the
existing HT/ LT ratio is only 1 :1.9 resulting in high technical
losses in LT lines.
Objectives of Feeder Separation
 Uninterrupted, quality power supply to domestic rural
consumers. By providing better quality and uninterrupted power
supply, there would be over-all development of Rural mass that
will improve their standard of living, improved economic condition
thereby over-all development in the company area.
 Flattening of load curve in a judicial way. Therefore reducing the
cost of power purchase and reducing the penalty for unscheduled
interruption.
 Better energy accounting for agricultural consumption
 Reduction of T&D and AT&C losses
 System strengthening by improving the infrastructure
 Improved voltage profile to every Domestic Consumer
 Theft of energy will be practically minimized
 Failure of Distribution Transformers will almost be negligible
 Chances of adding illegal connections will be completely
eliminated
Approval Of Government of MP
Energy Department, Go MP, has conveyed principle sanction of feeder
separation scheme vide L. No. 2995/13/2010 Dt. 05.04.2010.
Further Sankalp 2013 – feeder bifurcation, conveyed by Hon’ble
Secretary (Energy), Go MP, Bhopal, vide letter No. 4096 Dated 21st May’2010
07 Nos Districts are to be implemented in first phase (1st June’2020 to 31st
May’2012) and 07 Districts in second phase (1st January’2011 to 31st
December’2012).
The decisions taken in the meeting held in chairmanship of Hon’ble
Energy Minister on Dated 10.5.2010 conveyed vide letter No. 3895 Dated
12.5.2010 specifically specifies that :[1]
For the success of feeder separation works, project management
technique should be applied.
[2]
For feeder bifurcation works, project monitoring cell to be established
in the Company. The Chief of the Cell should be of the level of Chief Engineer
and Finance / Accounts Officer will also be posted in the cell. The DPRs
should be technically examined at company level. It should be ensured that
after execution of works, AT & C losses will be reduced.
[3]
After approval of tender and sanction from REC, works should be
started floating tenders after June’2010.
Main Benefits of Feeder Separation
 Theft of energy will be minimized.
 Failure rate of Distribution Transformers will be
minimized.
 Chances of running illegal motors during supply
“OFF” period are completely eliminated.
 Significant reduction in T & D Losses
 Improved voltage profile to every Domestic Consumer.
 Presently due to lengthy LT line and voltage drop, the
voltage received at the consumer end drops down. With
the provision of DTR's near to the consumer’s group
there will be improved voltage profile.
 The IRR of project is 19.56 % and pay back period 4
years and 3 months.
Scope of Work
 Providing engineering data, and drawing for Employer’s review,
approval and records.
 Supply, testing, packing, transportation and insurance from the
Manufacturer’s work to the site.
 Receipt, storage, insurance, preservation and conservation of
equipments at the site.
 Fabrication, pre-assembly (if any), erection, testing and putting into
satisfactory operation of all the equipments/ materials including
successful commissioning.
 In addition to the requirements indicated in this section, all the
requirements as stated in Technical specifications shall also be
considered as a part of this specification as if completely bound herewith.
 The Contractor shall be responsible for providing all materials,
equipments and services specified or otherwise, including survey, which
are required to fulfill the intent of ensuring operability, maintainability and
the reliability of the complete works covered under this specification.
 All services & activities required to be given contractually, by the
Contractor, during warranty period.
Survey
(i) GPS Survey of the existing 11 KV line radiating from 33/11 kV S/s, distribution
transformers and connected LT net work on the existing feeders shall be carried out. It
will cover mapping of 11 KV line with locations of existing distribution transformers,
existing LT net works (configuration of line should specifically be mentioned) along with
the pole wise details of load for agricultural pump consumers having permanent, semi
permanent and temporary pump connections and other categories of consumers ( like
domestic, non domestic, industrial, water works etc). All existing distribution transformers
will clearly be marked as mixed load, (agriculture with other load), only agriculture load
and other category load (exclusive of agriculture load) distribution transformer.
the data as above shall be prepared on shape file and same ought to be made
CYMDIST compatible or any other equivalent or superior GPS compatible software for
simulation, network analysis, and ‘what if’ analysis purpose.
(ii) Preparation of single line diagram with all the attributes, essential for simulation
through CYMDIST software indicating the locations of 33/11 KV S/s, HT and LT poles,
section wise distance, type of conductors, locations and capacity of distribution
transformers & pole wise & DTR wise connected load, locations of individual permanent
pump consumers and its load in HP, semi permanent pump consumers and its load in
HP, temporary pump consumers and its load in HP. If there is any other category of load
it should also be indicated including that for supply to ‘abadi’ area of the villages. The
names of the consumers along with load are also to be given.
Survey
(iii) In case the existing distribution transformer is supplying to both house hold consumers and
agricultural pump consumers, the arrangement to be made to separate the supply of agricultural
pump consumers from such distribution transformer, should be indicated, if necessary by
proposing a new transformer at suitable location either for agricultural pump consumers or
household consumers. In no case the agricultural pump consumers and house hold
consumer shall be served from the same transformer. The house hold supply shall not cover
the single bulb connection for lighting purpose allowed to the agricultural pump consumer.
(iv) Based on the aforesaid survey and load details, the Contractor shall design the proposed 11
KV and LT line network. The proposed network shall give route and type of feeder either
agriculture or abadi for new 11 KV line which shall be decided on the basis of techno-economic
consideration and got approved by the Project Manager. Survey shall also be carried out for new
proposed 11 kV feeders to separate supply of agriculture pump consumers from other category
consumers. It should also identify the LT line in abadi area of villages where conversion from
bare conductor to AB Cable is to be made and also specify the appropriate size / type of cable
based on CYMDIST analysis. The route of new line should also indicate tap line, DP structures,
angle locations and tapping locations and proposed distribution transformers 25 KVA, 11/.433
KV. The locations of the identified distribution transformers should be as close as possible to
load centre, necessarily radiating at least two LT circuits and shall be fixed after carrying out
simulation through CYMDIST. If necessary, the location of the existing distribution transformer
could be proposed for shifting. The load of the transformers should be limited to 80% of the
capacity. Survey should also be conducted for existing and proposed LT line in ‘abadi’
/agriculture area which will be connected to above DTR.
Survey
(v) Depending up on the route of the new 11 KV feeder, it will be necessary to shift the existing distribution
transformers to the new feeder so to achieve the object of segregation of agricultural pump loads and other
loads.
(vi) The new LT line whether for agricultural pumps or supply to households shall be extended on PCC poles
140 kg, with AB cable and not with bare AAA conductor.
(vii) The survey shall clearly indicate the locations where guarding for line crossing and road crossing is
required.
(viii) Survey should also indicate the numbers of existing poles which are leaning and are required to be
straightened. It should also indicate whether earthing is provided for the poles and proper ground clearance
is available. In case it is necessary to provide guarding for the 11 KV line crossing the road it should be
indicated.
(ix) The survey shall clearly indicate the spans where the ground clearance as per IE Rules is not adequate
and suggest measures like erection of mid span poles or Extension piece for raising the height etc.
(x) The survey should also bring out clearly the requirement of 11 KV VCB, control panel, CT/PT unit, and Tri
vector energy meter -/5 amps and associated materials for 11 KV bay of the exiting 11 KV feeder proposed
for separation of agricultural pump consumers from other consumers.
(xi) The existing and the proposed 11 KV line, distribution transformers shall be duly mapped on Survey of
India maps of appropriate scale of 1:50000. The Survey of India maps shall also be provided by the
Contractor at its own cost.
(xii) The LT network, looking to its small size, instead of superimposing it on above mentioned Survey of India
map, village wise Auto-cad map based on GPS survey shall be prepared for existing and proposed network
duly covering landmarks of a particular village.
(xiii)The Contractor shall arrange licensed version of CYMDIST software at its own cost. The software along
with the GIS software will be handed over to the Project Manager on completion of Project. The hard copies
(five numbers for each map) of final maps of high tension and low tension networks shall also be delivered by
Contractor to the Project Manager.
Consumer Indexing
Based on the data collected during the survey, the consumer indexing
and asset mapping will be done. Consumers should be appropriately
linked in the electrical network starting from LT pole to LT circuit to
distribution transformer to 11 kV feeders and finally to 33/11 kV S/s.
Formats for consumer indexing and assets mapping are enclosed in
Annexure F. Pole numbering starting from existing 33/11 kV S/s to 11 kV
feeder, distribution transformer and LT line will be done accordingly. The
consumer indexing database shall preferably be furnished on
acceptable database platform and the Contractor will also develop a
suitable interface between Employer’s metering, billing, collection
database with consumer indexing database. The interface must also
have data editing and error reporting facility. The source code of such
interface will be the property of the Employer.
The consumer indexing and asset mapping will be limited to the
consumers connected to the 11 kV feeders, both existing and proposed
covered under the scope of the works.
