Electrum Welcome You All @ PC Solo Theme Maximising Sale of Power and profit of VSTPS Presented by Vikas Gupta Anil kumar
Proposals Roof top solar feeding supply directly to Switchgear Roof top Solar feeding Power to DC Switchgear. Roof top Solar feeding Power to H2 Generation Plant. Power factor improvement of CHP HT feeders from Plant HT Switchgear 3
Proposals-1 Roof top Solar Power feeding to Switchgear (without Battery System) 415 V SERVICE SWGR Normal Supply 4
Proposals-1 Switchyard Building + Service Building Stage-III Potential 50 Kwp Tech Feasibility asserted by REDG based on Roof Area and Sun intensity Costing - 42Lacs Yearly Saving -PLF(18%)*50=9KW (INR 236520) Pay back Period- 10 years Maintenance free as no battery requirement- Economical & Sustainable Solution Proposed for Turbine floor / PT Plant as availability of Roof Space as well Switchgear loads. 5
Future Course of Action Step-1 : Area assessment Step-2 : Switchgear Identification Step 3 : Tech Feasibility Step 4 : Approval

Future Course of Action Step-1 : Area assessment Step 2 : Switchgear Identification Step 3 : Tech Feasibility Step 4 : Approval
Proposal-2 Roof top Solar Power Feeding directly to 220V DC Switchgear 11
Proposal-2 Depending upon the intensity of Sun, PV Cells used to generate , Inverter stabilize the AC output by controlling the rectifier. Solar Panel Solar Panel ACDB Inverter Synscope Solar Panel Controlled DC Voltage Charge Controller DCDB Here to control the DC voltage, solar charge controller is required, now manufactures are available (Vikram Solar , Moser Boer etc) If proposal converted to reality then this would be the First Project ,solar directly charging the 220 DC Switchgear. 12
Proposal-2 Capacity( Switchyard DC DB) 30KWp ( calculated as normal current 60A with 240 V)+ Roof space available Costing 20 lacs ( Budgetary offer of Vikram Solar) Yearly Saving -PLF(18%)*30=5.4KW (INR 141912) Pay back Period-10 years Maintenance free as no battery requirement and invertors - Economical & Sustainable Solution. VSTPP has a potential of 200KWp through this , If Automation system is included then approx 300KWp- Economy of Scale 13
Proposal-3 Roof top Solar Power Feeding directly to Hydrogen generation plant. 14
Proposal-3 If proposal converted to reality then this would be the First Project ,solar directly being used for Hydrogen generation Capacity 30KWp ( calculated as normal current 500A with 60 V)+ Roof space + open space area available for solar panel. Costing 20lacs ( Budgetary offer of Vikram Solar) Yearly Saving -PLF(18%)*30=5.4KW (INR 141912) Pay back Period-10 years Maintenance free as no battery requirement and invertors - Economical & Sustainable Solution. 15
Proposal-4 CHP HT LOAD FROM STAGE-I Gen Total HT Load (approx) = 2868 KW E 5 GT 4 Average Power Factor = 0.6 UT 3 HT Switchgear 2 Voltage = 6.6 KV 1 CHP HT LOAD Capacitor 2868 KW / 0.6 PF
For CHP HT Load When power factor is improved from 0.6 to 0.95 Voltage Voltage KW PF1 PF2 KVA1 KVA2 KVA reduction KVAr1 KVAr2 KVAr reduction current1 current2 Current reduction Power Loss 115 % reduction in power loss Reduction in power loss 6600 6600 2868 0.6 0.95 4780 3019 1761 3824 943 2881 418 264 154 58.24 67
COST BENEFIT ANALYSIS Power Saving (Kw) Energy saving annually Kwh (million units) Saving annually in Rs (1.50/KWH), Lakhs Capacitor compensation KVAR required Appx Investment required (600 Rs/KVAR), Lakhs Pay back period in years 67 0.6 8.75 1761 10.56 1.2 Implementation- Switchgear R&M
