Simulation test platform of process layer of digitalization transformer substation

Abstract

The invention discloses a simulation test platform of a process layer of a digitalization transformer substation, which is characterized by comprising a PC carrying out communication through the Ethernet and a simulation test embedded device, wherein the simulation test embedded device is connected with a tested protecting and monitoring device; the PC is internally provided with a simulation module used for simulating a dynamic process of process layer equipment to generate required data and downloading the data into an FLASH of a corresponding functional module of a simulation test device; and the simulation test embedded device is used for receiving simulation data of the PC, simulating the process layer equipment as required so as to send and receive the data according to a standard message, carrying out information exchange with test and control protection equipment of a spacer layer in a station, analyzing a received message and then returning an analysis result to the PC. The platform simulates a process layer equipment group of a certain voltage level through high-efficiency, economical and convenient configuration and realizes the test operation of a transformer substation equipment system.

Description

technical field [0001] The invention follows the IEC61850 standard—the only international standard for substation communication networks and systems, and proposes a design method for a digital substation process layer simulation test platform with a new architecture based on optical fiber communication technology, and belongs to the field of substation comprehensive automation technology. Background technique [0002] With the development of digital substation technology, due to the use of ECT, EVT and intelligent circuit breakers based on optical and electronic principles, digital substation monitoring and control, fault analysis and operation management are all transmitted through optical fibers, conventional simulation signals and control cables will gradually Replaced by photoelectric digital signals and optical fibers, the input and output of the measurement, control and protection devices are all digital signals. The substation communication network is further extended ...
