Process level equipment with longitudinal optical fiber channel receiving and transmitting functions

Abstract

The invention relates to process level equipment with longitudinal optical fiber channel receiving and transmitting functions. The process level equipment comprises a combination unit module, an optical fiber receiving and transmitting module, an intelligent terminal module, a switch quantity data memory module and a GOOSE receiving and transmitting module, wherein switch quantity acquisition of one interval can be realized and is transmitted to a process level network through GOOSE; a GOOSE command on the process level network is received to realize control over a breaker and a knife switch of one interval; digital quantity information or analog quantity information of a mutual inductor is received; data of an optical fiber channel is received; the digital quantity information or the analog quantity information and the data are synchronized and then transmitted to the process level network through an SV sampling value; the switch quantity data of the local side and the opposite site is stored in the switch quantity data memory module; and data exchange and sharing are realized in the equipment. According to the equipment, functions of an intelligent terminal, a combination unit and an optical fiber channel are integrated, the number of the process level devices is reduced, the on-site mounting size is reduced, the engineering design is simplified, and synchronization of local side data and opposite side data is realized in the equipment; and the process level equipment is easy and reliable to realize.

Description

technical field [0001] The invention belongs to the process layer equipment of an intelligent substation, and relates to a process layer equipment with the function of transmitting and receiving a longitudinal optical fiber channel. Background technique [0002] Smart substations are a development direction of substations in smart grids. Currently, smart substations mostly adopt a typical three-layer structure: process layer, interval layer, and station control layer, such as figure 1 As shown, in IEC61850, there is a clear definition of the equipment functions in these three layers. Among them, the equipment in the process layer is mainly the merging unit and the intelligent terminal. execution. [0003] At present, the merging unit and the intelligent terminal device are combined into boxes separately, and each is independently a single-function device. In engineering practice, this method has highlighted many problems, such as difficulty in information sharing, duplicat...
