APEPDCL launches real-time data acquisition system

Visakhapatnam Chairman and Managing Director of APEPDCL K. Santhosha Rao on Friday inaugurated the RT-DAS (real-time data acquisition system) control system under the IPDS scheme of the Government of India.

The facility is introduced as part of "Ajadi ka Amrit Mahotsav" celebrations marking 75 years of India's Independence at APEPDCL Corporate Office here.

The Power Finance Corporation Ltd. (PFC) is the nodal agency for the IPDS scheme.

Rao said that this project was completed in September 2021 after being sanctioned in December 2018 at a cost of Rs.4.80crore.

RT-DAS is implemented in 116Nos. 33/11kV sub-stations, 437Nos. 11kV feeders feeding the 36 Nos. IPDS town areas. The required hardware/ equipment feeder permitted terminal unit (FRTU Panels), multifunction transducers (MFTs), etc were installed for all the 11KV feeders.

By implementing the RT-DAS project in APEPDCL, the real-time data, i.e. voltage, current, power, energies, planned and unplanned Interruptions from 11KV town feeders are available for measurement of SAIDI/SAIFI in all 33/11KV Sub-Stations of 36 Nos RAPDRP & IPDS Non-SCADA Towns (i.e. excluding Visakhapatnam).

An energy audit can be conducted. In the RT-DAS application, data is being captured using FRTUS (feeder remote terminal units) and MFTS(multi-function transducers). The major highlight of this system is that just by having a glance at the RT-DAS dashboard, the management will be able to know the current situation of power supply in all of the 437 feeders of the DISCOM.

This shall also enable the DISCOM to know whether a particular feeder is down due to a fault–an unplanned outage or planned maintenance activity. Further, the CMD said that regular monitoring reports received from the RT-DAS system, uninterrupted power supply to the consumers without any interruptions may possible.

APEPDCL Directors K. Rajabapaiah, B.Ramesh Prasad, D. Chandram, and CGM(IT) C. Srinivasa Murthy, from PFC S.Srininvasa Rao CGM(PR), Ashok Rathod GM(IPDS) and other officers from APEPDCL were present.
