Power System Operation Corporation Ltd.
(A Government of India Enterprise)
Southern Regional Load Despatch Center
Role Of SRLDC...
- SRLDC is performing the responsibility of Supervision,
monitoring and control of integrated operation of Southern Regional grid in coordination
with all State power utilities in the Region, Central generating Stations etc. to
ensure stability and security of the grid operation in accordance with IEGC. To aid decision process RLDC and all
SLDCs in the Region are taking support of a modern
State of the art SCADA and communication system set up in SRLDC and all
SLDCs to obtain power system data in real time from all sub-stations
and generating stations in the Region.
Energy Management System (EMS) packages i.e. Load / inflow forecasting, resource
scheduling and commitment, State estimation, power flow studies, contingency analysis,
optimal power flow and real time generation application etc. provided along with the SCADA system enable the system operator
at SRLDC in taking the correct decision
in planning contingency handling.
- Coordinating and issuing drawal
schedules of State Power Utilities from all Central Generating Stations and dispatch
schedules of Central Generating Stations. For this the Central Generating Stations
declare the availability of their stations one day in advance to SRLDC who works
out and conveys the SLDCs of the State power utilities
their entitlement from Central Generating Stations.
The SLDCs, in turn, assess the demand and availability
of the State or DISCOMS, as may be the case, based on States/DISCOMs
generation availability, bilateral agreement etc. and conveys the consolidated requisition
of the State to SRLDC. Accordingly
SRLDC issues the final drawal schedule of State power
utilities and dispatch schedule of Central Generating stations for the next day
which becomes the datum for settling the commercial issues.
- Facilitating transactions of power under short-term
and long term open access for inter/intra regional exchanges following regulations
and procedures issued by the Central/State Electricity Regulatory Commission and
Central Transmission Utilities.
- The RLDCs of the Region,
where point of drawal of electricity is situated, shall
be the Nodal Agency for the short-term transmission access in case of open access
in inter-State transmission.
- Collecting the meter readings from all interconnected
/ boundary point, central generating stations, computes the average energy for 15
minutes time block, compares the deviations from the schedule and computes the unscheduled
inter change (UI) charges for the corresponding time block based on UI rates of
average frequency during the time block.
- Issuing clearance for outage of grid elements for
Security and Economy in Power Transmission
