Embodiment Construction

[0017] The process layer device with longitudinal fiber channel transceiver function realizes the functions of merging unit, intelligent terminal and fiber channel data transceiver in one device. The three functional modules share data through the internal shared memory mode. Its structure is as follows: image 3 As shown, the process layer equipment is suitable for the intelligent substation adopting the IEC61850 standard. Process layer equipment includes merging unit module, optical fiber transceiver module, intelligent terminal module, switch data storage module and GOOSE transceiver module. The optical fiber transceiver module can obtain the analog data, switch information, protection information and fiber channel configuration information of the local side. The implementation of this module is the same as that of the optical fiber transceiver module in the traditional substation. It can use dedicated fiber channel or multiplex PDH or SDH The digital interface of the syste...

Abstract

The invention relates to a process layer device with the function of transmitting and receiving a longitudinal optical fiber channel, including a merging unit module, an optical fiber transceiver module, an intelligent terminal module, a switch data storage module and a GOOSE transceiver module, which can realize switch value collection at one interval, through GOOSE is sent to the process layer network, and the GOOSE command on the process layer network is received to realize the control of an interval circuit breaker and knife switch; receive the digital or analog information of the transformer, and receive the data of the optical fiber channel, after synchronization Send the SV sampling value to the process layer network; store the switching data of the local side and the opposite side to the switching data storage module, and realize the exchange and sharing of data inside the device. The device of the present invention integrates the functions of the intelligent terminal, the merging unit and the fiber channel, reduces the number of process layer devices, reduces the size of the on-site installation, simplifies the engineering design, and realizes the synchronization of the data on the local side and the opposite side inside the device. Simple and reliable implementation.

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...
