Projectsbeing handled by SLDC(P)
Supervisory Control and Data Acquisition /Energy Management System (SCADA/EMS) commissioned by M/s. Power Grid Corporation of India Limited (PGCIL) in Northern Region on Unified basis is operational at SLDC, Patiala since 2002 and real time status of the grid is available to the load dispatchers around the clock which further helps them to take corrective actions for operating the grid in efficient manner. For better viewing of data at control centre, a large display screen i.e. Video Projection System (VPS) has been installed. Further to ensure Uninterrupted Supply to the SCADA/EMS hardware, the provision of Uninterrupted Power Supply (UPS) of sufficient capacity has been made at the control centre. Existing SCADA/EMS related hardware and software supplied by M/s Areva has been upgradedby M/s Siemens System. Provision of backup control centre for main SLDC control centre has been made under the new system installed by M/s Siemens Ltd.
Integration of RTUs with the SCADA/EMS:
All the generation plants of PSPCL, important 220KV and 132KV substations of PSTCL are already covered for remote data acquisition and control by putting up RTUs/SAS. Tender for Design, Supply, Commissioning and Integration of 47 No. Remote Terminal Units (RTUs) for SCADA/EMS system is being implemented. 41 No. RTUs have been commissioned under this project and the remaining 6 No. RTUs are expected to be commissioned during 2015-16.
Implementation of Intrastate boundary metering cum Transmission Level Energy Audit Scheme in PSTCL
Under this project, 750 No. Availability Based Tariff (ABT) meters and 450 No. Conventional Energy Meters (CEM) has been procured. ABT meters are being installed at interface/boundary points of PSTCL with PGCIL, BBMB, HP, PSPCL & IPPs to calculate the amount of energy transmitted through boundary points and for calculation of overall transmission losses of PSTCL. Also, CEMs are being installed at 400KV, 220KV and 132KV substations of PSTCL for energy audit purposes. Further, Centralised Energy Centre (CEC) of PSTCL has been established at Ablowal, Patiala
