2 FEEDER SEPARATION SCHEME OF WEST DISCOM, INDORE

3 GEOGRAPHICAL MAP OF WEST DISCOM

4 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

5 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.

6 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

7 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 21 st May’2010 07 Nos Districts are to be implemented in first phase (1 st June’2020 to 31 st May’2012) and 07 Districts in second phase (1 st January’2011 to 31 st 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.

8 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.

9 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.

10 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.

11 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.

12 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.

13 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.
