1. Introduction
This is one of latest AMI system solution which combines almost all kinds of wireless communication, including Zigbee, PLC, GPRS and Wifi. YTL provides you the whole solution including smart meter, DCU and AMI system.
It integrates remote reading, control and analysis function. This is the answer to your specific needs: from the reliable commercial meter to the complex measuring device with comprehensive additional functionality for advanced data acquisition and flexible tariff control.
The main characteristic and advantage:
1-Modular communication units provide the right choice for the best data channel at all times
2-Plug and Play modules offer you full freedom of choice for deployment of new communication technologies.
3-The utility can read, set meters remotely, which reduces the cost and save time of reading
4-Remotely or locally disconnect/connect load of users.
4-The users can read energy consumption through the in home display which is installed in the house or other convenient places.
5-Enhanced communication capability through DLMS protocol
6-High performance with low cost, it is the best option of AMI solution.
2. Features and Technical Parameters
2.1 Features of system components
1-Smart meter(single and three phase): Include all kinds of function for smart metering, which is the answer to your specific needs. With plug and play modules, it also offer you full freedom of choice for deployment of new communication technologies
2-In home display(IHD): Receive and display the data from collector. The data will be displayed on the LCD. It is installed indoor where is easy to check the reading.
3-DCU: It handles the communication between the head end system and smart metering. It reads metering data automatically and can send data to the system or store data for later retrieval by system. It transfers messages to and from the head end system using standard DLMS/COSEM communication protocol
3-AMI system: Adopt international Protocol(DLMS/COSEM) ; Support both Windows & Linux; Line Loss Analysis; Meter Geographic Information System; Interface with other systems;

2.3.2.1 Characteristic:
1-Measure and display current date and time; kWh; kvarh; Maximum kW and kvar demand; Cumulative kW and kvar demand; Instantaneous active and reactive power; Instantaneous voltage current and power factor.
2-Time of use metering: the smart meter can be programmable to record import and export energies(kWh and kvarh) and import and export demand(kW and kvar) on different rates.
3-Load profile function: the smart meter is able to record 15-minute three decimal points load profile data with 4 channels consisting total import kW, total import kvar and total export kvar demand.
4-Meter registration: the smart meter can be registered with Data Concentrator Unit(DCU) ot AMI Central System(consisting of Meter Data Management System(MDMS). Head End System and relevant systems and accessories) automatically.
5-Automatic meter reading: the smart meter can transmit measured quantities to DCU or AMI system automatically.
6-Remote load disconnect and reconnect: the smart meter has a remotely controllable disconnect/reconnect switch for supporting load limiting, load shedding and prepayment function.
7-Tamper detection: the smart meter can detect and record attempted tampering event and also show alarm signal on LCD. And the tempering events can be sent to AMI system automatically.
