Intelligent power gateway meeting IEC61850 standard

Abstract

The invention discloses an intelligent power gateway meeting an IEC61850 standard. A communication port is divided into a downlink port and an uplink port, communication with conventional communication protocol equipment is performed by the downlink port, and communication with a background monitoring system is performed by the uplink port. Each kind of communication protocol library is mounted in main program architecture according to a dynamic link library mode, and used for collecting data of the conventional communication protocol equipment of the downlink port, and storing the data into a local real-time database. The uplink port can acquire the equipment data from the local real-time database, and uploads the data to the background monitoring system via an IEC61850 protocol. According to the gateway provided by the invention, the IEC61850 protocol library can achieve flexible mapping between data attributes of an ICD model file and data points of the local database via a short address (sAddr) of the ICD model file, and achieve intelligent conversion with the IEC61850 protocol without modifying software.

Description

technical field [0001] The invention relates to an electric power intelligent gateway conforming to the IEC61850 standard, which can easily realize intelligent conversion between various conventional protocols in an intelligent substation and the IEC61850 protocol. Background technique [0002] In recent years, with the vigorous promotion of the IEC61850 protocol standard and smart substations, the growing communication technology has put forward new requirements for the communication between devices in the substation. The IED (Intelligent Electronic Device) of the smart substation uses IEC61850 communication, and some device data based on communication protocols such as Modbus, IEC60870-5-103, and CDT will not be able to be connected to the data network of the smart substation. [0003] At present, most electronic equipment in smart substations (such as protection, measurement and control equipment) have IEC61850 communication functions, but there are still some low-end pro...

Problems solved by technology

The IED (intelligent electronic device) of the smart substation uses IEC61850 communication, and some equipment data based on communication protocols such as Modbus, IEC60870-5-103, and CDT will not be able to be connected to the data network of the smart substation

[0003] At present, most electronic equipment in smart substations (such as protection, measurement and control equipment) have IEC61850 communication functions, but there are still some low-end products (such as low-voltage instruments, watt-hour meters, online monitoring equipment) that do not have IEC61850 communication functions. It has conventional communication functions such as modbus, IEC60870-5-103, CDT, etc., so it is necessary to invent a device that can flexibly convert various conventional protocols into IEC61850 communication protocols, so as to realize the seamless connection between conventional equipment and the background monitoring system of intelligent substations
