1. Objective

1.1. Introduction

The main purpose of this document is to explain the Energy Metering and Management System for the Switchboards in GFC Plant. The offered system interfaces with Rishabh make (3440) for Main & DG Incommer & Rishabh make (Delta Energy) for outgoing Feeders, Energy Meters and provide comprehensive energy management systems. All the meters will be networked to Energy Management System for reporting, archiving and performance benchmarking.

1.2. Working Philosophy

The scope includes Supply of Serial Converter (RS 485 to RS 232) and EnMS Software for Energy Management Platform.

Serial Converter: Advantech make Serial converter ADAM 4520 is used to convert the Metering loop (RS 485 to RS 232) for integration in EnMS PC.

EnMS: Energy Management System, can communicate with any make Energy Meter (over MODBUS), Easy Analysis of Generation & Consumption with inbuilt analytics, fully customizable LCD Display output to broadcast Energy Performance Data at various Boards
