BSES Snapshot
† Distributing to over 2.3 million customers
„
„
2,644 MW of peak demand
Adding 0.2 million customers every year
† AT&C losses reduction of >24% (since takeover)
„
„
„
In BRPL from 51% to 27%
In BYPL from 63% to 29%
Which is 5% reduction per year, as against National Average of <1%.
† Major improvement across quality of supply, customer
care, technology infusion and reliability
† Implemented and integrated GIS, SAP, SCADA and
OMS
† Single window and secured business application CAS
† AMR for input energy points and key consumers
BSES Delhi Network Overview
Technology for Operational efficiency
Operations
Earlier
Current
† Load shedding –avg. 6hrs/day
† Poor voltage quality
† Long restoration period
† Missing periodic asset health check
† Missing asset data
† Poor network visibility
† Implementation of SAP, GIS,
Impact
- Load shedding decreased by 98%
- Quicker fault repair
- Stable power supply
- Reduced restoration time through remote ops.
- Increased Reliability
- 90% complaints attended in less than 2 hrs
SCADA and OMS
† Entire network mapped on GIS
† Manpower and resource
management through OMS
† Automated SMS escalation of
faults and breakdown
† Job allocation & tracking
SCADA System
SCADA – Supervisory Control and Data Acquisition System
†Used as enterprise-wide management of the BRPL/BYPL Electrical Networks
†Envisioned for Centralized Control and Monitoring of the Complete Electrical
Network
†Combination of Hardware and Software Systems connecting to Main Control
Centre (MCC) and Back-up Control Centre (BCC)
†Availability of Real-time, Accurate and Consistent information of the Electrical
system
†Faster Fault Identification, Isolation and System Restoration
†Provides for efficient operations translating into economic benefits
SCADA IT Infrastructure
† SCADA has control centers i.e. MCC At Balaji South Delhi (Master
Control Center) and BCC at Nehru Place (Back-up Control Center)
† The SCADA application servers are placed at both MCC as well as BCC
† There are 118 Grid locations connected to both MCC and BCC through
2Mbps links (optic fiber)
† For redundancy, if the primary link between MCC and Grid fails, the links
to BCC will be used for SCADA operations
† The VSAT link is provided as a second backup to the Grid station and is
used only for SCADA traffic
† The BCC at Nehru Place that has connectivity to RDN Network (Mumbai)
SCADA Network
Advantages of SCADA
† Improves visibility of the system
† Improve response time
† Enables to closely monitor the system
† Helps in analyzing the trippings and deciding the action to be taken
† Operations from one point
† Prompt action
† All the real time data at finger ends
† Accurate system loading is available, gap in demand and availability is
known
Benefits after SCADA implementation
‰Reduction in Maintenance cost: 10 % reduction in network and component
maintenance
‰Better operation of network, better planning and co-ordination
‰Reduction in losses on account of better optimal network operations
‰Reduction in Outages
9 Due to faster fault isolation and restoration
9 Better switching procedure management
9 New and more efficient tools/operator functions

Distribution Management System
† DMS is set of computer-aided tools to Monitor, Control and Optimize the
performance of Distribution System
† Provides On – Line Real Time Data of 11 KV Network
† Help in Monitoring the quality of Power Delivery to consumer
† Provide Information on each Distribution Network Component
DMS Applications
† Operations Monitoring and Control
† Fault Isolation and System Restoration
† Outage Management system
† Crew Management
† Distribution Power Flow
† Distribution Load Forecasting
† Intelligent Alarm Processing function

Grid Automated Meter Reading
† Remote Collection of Energy
Input Data
† Technology for Data
Communication at 66/33KV
9 Fiber Optic / VSAT
† Technology for Data
Communication at 11KV
9 CDMA, GSM and GPRS
† Implemented at 66/33 and 11
KV networks
Benefits of AMR
†
†
Affordable, Accurate and Reliable Meter Reading
Capturing minutest of energy details on 5 minutes basis like monitoring
and logging of
„ Voltage, Current and Power factor
„ KWh, KVARh and KVAh
†
Alarm feature to draw attention of the operator to any breach of various
parameters beyond preset limits
†
Accurate estimation of losses
†
Significant increase in Operational Efficiency
†
Reduce reliability by Identifying, Assessing and Responding to outages
more efficiently
†
Facility to generate spread sheet and MIS reports on System outage /
Down time of the Feeders, Daily Peak loads & Voltage Profiles
