DL/T645 is Multi-function watt-hour meter communication protocol. It standardizes the physical connection and protocol of the data exchange between the multi functional electric energy meter and the data terminal equipment.
DL/T 698.41 is Master Station Communication With Data Acquire terminal Communication Protocol. It provides for power users to use the power information collection system and the collection terminal between the data transmission of the frame format, data encoding and transmission rules. The relevant standard is Q/GDW 376.1.
DL/T 698.42 is Concentrator Downward Communication Protocol. It provides frame format, the encoding and transmission rules for low pressure concentrator and electric energy data transmission in the electric energy information acquisition and management system. The relevant standard is Q/GDW 376.2.
IEC60870-5-101 basic telecontrol tasks communication protocol provides basic remote message communication between the master station and the remote sub station. It uses data circuit to communicate between the master station and each remote sub station.
IEC60870-5-102 power system electric energy measurement and transmission communication protocol provides the transmission protocol for electric energy metering terminal and power station of electric energy metering system of power network to transmit electric energy, remote measurement and other relevant data.
IEC60870-5-103 the standard of information interface for relay protection equipment provides the information interface specification for relay protection equipment (or measurement and control equipment).
Q/GDW 376.1 is Master Station Communication With Data Acquire terminal Communication Protocol.
