Embodiment Construction

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0061] Network communication technology is the basis for interactive transmission of information in intelligent substations. The technology used must meet the requirements of the substation business system for information transmission time, bandwidth, and safety and reliability. At the same time, it should adapt to the trend of technological development such as deep integration of primary and secondary equipment.

[0062] The communication network in the substation is a dedicated data communication network used to carry functional services such as protection, measurement and control, metering, PMU, and fault recording. According to different applications, the network information in the substation includes four types: GOOSE, SV, MMS, and time synchronization information. .

[0063] Such as figure 1 As shown, it is a schematic diagram of a remote monitoring sy...

Abstract

The invention provides a centralized configuration and remote monitoring system for a network communication device in a substation. The system performs centralized configuration and remote monitoring of the network communication device in the substation. The system is characterized by comprising a remote control communication module, an agent module, a protocol module and a communication terminal module in communication connection sequentially; the agent module, the protocol module and the communication terminal module are arranged in the substation; and the communication terminal module is connected to the network communication device. Management control information of the network communication device is transmitted in an out-of-band monitoring management mode by adopting optical fibre, visible light, wireless and power line carrier communication technology manners; a monitoring signal transmission channel of the network communication device is constructed economically, flexibly and effectively; the centralized configuration, remote monitoring and control problems of the network communication device in the substation can be solved; the reliability and the operation and maintenance level of substation equipment can be improved; and automatic and intelligent operation management requirements of the substation can be satisfied.

Description

technical field [0001] The invention belongs to the field of power systems, and relates to a remote monitoring system, in particular to a centralized configuration and remote monitoring system for substation network communication devices. Background technique [0002] In order to meet the needs of intelligent substations, future substation equipment will gradually move towards functional integration and structural integration, the integration of primary and secondary equipment will be closer, and the boundaries will be more blurred. The realization of comprehensive analysis and automatic cooperative control is the key to the intelligentization of substations, and the digitalization of equipment information, functional integration, compact structure, and maintenance automation are the development directions. [0003] The IEC 61850 standard is a complete communication standard for substation automation systems and the most important supporting technology for the construction o...
