Abstract

The invention discloses an IEC 61850 digital distance electric power data collecting method which adopts configuration tools to carry out modeling configuration to electric power data so as to generate corresponding configuration files, and adopts a communication module to complete data collection according to data content and service types which are defined by the configuration files. Configuration in the whole process is flexible and the data required for communication can be customized according to actual transmission requirement. The invention also discloses an IEC 61850 digital distance electric power data collecting apparatus comprising a main processor module, a network-card module, an optical-fiber converter module, an interface module and a storage module, wherein the main processor module is respectively connected with the network-card module, the optical-fiber converter module, the interface module and the storage module. The invention can collect digital electric power meter through Ethernet interfaces and also can store and transmit the data so as to lead the data to be transmitted to converting station networks and realize information sharing.

Description

technical field [0001] The invention relates to a method and device for collecting digital remote electric energy, in particular to a method and device for collecting digital remote electric energy based on IEC 61850. Background technique [0002] The design idea of ​​IEC 61850 standard is advanced, which represents the development direction of substation automation technology. It is one of the core technologies to realize digital substation and has a profound impact on the entire power automation technology. [0003] Before the introduction of the IEC 61850 standard, digital remote electric energy collection terminals in substations generally used serial communication protocols, and substation automation systems generally used Ethernet communication methods, making it impossible for digital remote electric energy collection terminals to be directly connected to substation automation systems. Switching through equipment such as public information management machines not only...
