INTRODUCTION OF SMART GRID

ELECTRIC GRID + IT = SMART GRID• The smart grid involves the application of

digital technologies and information management practices and is a core ingredient in the ongoing modernization of the electricity delivery infrastructure. The rate of smart grid technology adoption varies across the nation and depends largely on state policies, incentives, and technology experience levels.

AMI(Advanced Metering Infrastructure )

• Advance metering is a metering system which record the customer power consumption aloe with other hourly, the measured data fastly over communication network to a central collection point.

AMI(Advanced Metering Infrastructure )

BENEFITS

• Anti theft.• Two way communication.• Real time and Automatic billing.• Improved billing and customer support

operations. • Improved outage management from meters

that alert utilities when customers lose power.

Definition of Smart Meter

• Smart is a new kind of energy meter. This next generation of meter are a replacement for your existing meter and send electronics meter reading to your energy supplier automatically.

• There are both gas and electricity smart meters.

Smart meter

BENEFITS

• Distribution automation system.• Energy management system.• Intelligent network system.• Demand side management system• Grid modeling, simulation and design system.

Smart Meter Technologies

• The Smart Meters collect data locally and transmit via a Local Area Network (LAN) to a data collector. This transmission can occur as often as 15 minutes or as infrequently as daily according to the use of the data.

• The collector retrieves the data and may or may not carry out any processing of the data.

• Data is transmitted via a Wide Area Network (WAN) to the utility central collection point for processing .

• Since the communications path is two -way

Basic Types of Smart Meter Systems

There are two basic categories of Smart Meter System technologies as defined by their LAN. Radio Frequency (RF). Power Line Carrier (PLC).

Radio Frequency (RF) Smart Meter measurements and other data are transmitted by wireless radio from the meter to a collection point. The data is then delivered by various methods to the utility data systems for processing at a central location. There are different method of Radio Frequency (RF).1.Mesh Technology The smart meters talk to each other to form a LAN cloud to a collector. 2.Point to Point Technology The smart meters talk directly to a collector, usually a tower. The tower collector transmits

Power Line Carrier - PLC

Smart Meter measurements and other data can be transmitted across the utility power lines from the meter to a collection point, usually in the distribution substation feeding the meter. Some solutions have the collection point located on the secondary side of a distribution transformer. The data is then delivered to the utility data systems for processing at a central location. The utility billing, outage management, and other systems use the data for operational purposes

Smart Meter Installation

The planning for the installation of Smart Meters is just as

important as the actual installation itself. Different organization which install smart meter.I. The National Electric Safety Code (NESC) for utility wiring. II. The National Electric Code (NEC) for home wiring. III. ASNI C12.1 – Code for Electricity Metering.
