Power substations to be remotely monitored

Panjim: The power sub-stations in Goa will now be remotely monitored and controlled as the State Government proposes to spend Rs 600 crores to automate the power distribution system across. Move is also on to introduce Time-of-Use (ToU) tariff system, which will help customers to avail lower tariff during non-peak hour.

Goa Electricity Department (GED) in their business plan 2019-20, 2021-22 submitted before the Joint Electricity Regulatory Commission (JERC) has said that it wants to automate its distribution network being a core sector which has a direct interface with the consumers.

The entire focus will be two dimensional-part I that is analysis based investment plan for strengthening of network, for which new substations, lines, interconnectors, re-conductoring, transformer augmentation, revamping of Sub-Stations, High voltage distribution system, load balancing/feeder segregation, HT/LT Aerial bunched cables, capacitor banks/reactors at 11 KV and 33 KV and laying of Under Ground cables in densely populated areas, have been planned.

“Part II is a quantum jump in reliability, for which plans are afoot to have Grid Sub-Station automation and integration with SCADA, Strategic distribution RMU (Ring Main Unit), FPI (Fault Passage Indicator) and Integration with DMS (Distribution Management System), Outage management system and integration with GIS (Gas Insulated Substations) and CRM, provisioning compatibility with SMART technologies etc,” the GED said.

“In line with this objective GED is taking up implementation of SCADA (Supervisory Control and Data Acquisition), DMS, Distribution Automation, and Sub-Station Modernisation and Automation,” it added. The estimated cost of the works proposed to be executed is to the tune of say Rs 550 crores to Rs. 600 crores.

Substation Automation (SA) involves equipping the substation with digital relays and connecting them through reliable and secured communication systems with the control centre so that the substation can be remotely monitored and operated. [H]
