Abstract

The invention discloses a multifunctional intelligent data collecting device, which comprises a power source board, a CPU board, a CPU expansion board and a bus back board and at least comprises one of an AC sampling board, an AS sampling board and an FT3 serial sampling board. The device cannot only support network transmission of IEC61850-9-2 standard and point-to-point transmission, but also supports point-to-point transmission of IEC60044-8 and an extension protocol thereof. The device can realize collection and transmission of data, has a cascade function, and can receive sampling data and combine the sampling data with data in the device. The device has intelligent PT paralleling and voltage switching functions, sends and receives state information and alarm information via a GOOSE (Generic Object Oriented Substation Event) message, and supports a GOOSE network control function. The device supports an IEEE1588 high-accuracy network time setting function, supports a GMRP (Garp Multicast Registration Protocol) protocol and automatically carries out VLAN (Virtual Local Area Network) division. The device has an intelligent debugging function and can carry out flexible configuration, dynamic simulation, automatic diagnosis, automatic check, and the like.

Description

technical field [0001] The invention relates to a multifunctional intelligent data acquisition device suitable for the requirements of intelligent substations, belonging to the technical field of electric power automation. Background technique [0002] As the power system develops in the direction of large capacity, ultra-high voltage and ultra-high voltage, the primary and secondary equipment develops in the direction of miniaturization, intelligence and high reliability. With its small size, light weight, strong anti-electromagnetic interference ability, wide dynamic range, not easy to be saturated, simple insulation structure, and easy digital signal transmission, the electronic transformer complies with the development requirements of electric power engineering and has been widely used. application. In the digital substation construction stage, the device for collecting data from electronic transformers—the merging unit—is widely used. The electronic transformer is conn...
