Project Description

---

Automated Meter Reading (AMR) is a technology that enables automatic collection of energy consumption, diagnostic, and status data from meters, and transfers this information to a central database for billing, monitoring, and analysis. This eliminates the need for manual meter reading and ensures greater accuracy, speed, and efficiency.

Sandur Power is one of the largest hydro power plants in Karnataka, located in the Udupi Hosangady district in the southern part of India.

The system involves seamless communication with energy meters through a Gateway, SCADA software, and a Mobile application. The local SCADA system is primarily used for monitoring live instantaneous values from the energy meters in real time.

The substation comprises two sections: the generation station side, which is equipped with 8 DLMS energy meters (L&T make), and the distribution station side, which has 3 DLMS energy meters (Secure make).

Data from both sides of the substation is collected and displayed on the control room PC, allowing operators to view real-time energy values continuously.

The SCADA system provides comprehensive visualization, including bay-wise screens, individual bay screens, detailed metering information screens, and an overall architecture screen for easy monitoring and control.

Silent features of this project

---

On the generation side, data from all 8 meters is being received successfully. The Gateway downloads the required files to the system on a daily basis, and the instantaneous values are updating accurately every second.

On the distribution side, data from all 3 meters is being received successfully. The Gateway downloads the files to the system daily and is connected to the NT300 modem, which transmits the data to SLDC every day. The instantaneous values are also updating correctly every second.

At the generation station, the Gateway communicates via the ETH-1 Ethernet port through an FO media converter. It sends online data to the Sandur Control Center, receives data from all 3 meters, and downloads LoadSurvey and Midnight files to the system daily. The Gateway is also connected to the NT300 modem, which forwards the data to SLDC daily. The instantaneous values continue to update correctly every second.

At the distribution station, the Gateway communicates using the ETH-1 Ethernet port through the NT300 and R201 Nimbus router. It sends online data simultaneously to both SLDC and the Sandur Control Center. Data from all 3 meters is being received, and LoadSurvey and Midnight files are downloaded from the Gateway to the system on a daily basis.

The LMS Mobile is delivered as a web application developed using the MERN stack and deployed on the intranet through a VPN server. The application is fully responsive, ensuring seamless access across mobile phones, tablets, and laptops. Authorized users can securely access the system through the VPN IP address and monitor real-time data from anywhere in the world.

Reports and statistical analyses are available within the mobile application. These include daily analysis, range-based analysis, and monthly analysis. Users can view logs with minimum, maximum, and average values, download logs in PDF or Excel formats, and customize log views by selecting columns on a per-meter basis for flexibility.
