Embodiment 1

[0041] like figure 1 As shown, it is the application object of this embodiment, that is, the tested IED device. All inputs and fixed values ​​(parameters) of the IED device functions are controllable and settable, and all outputs are measurable.

[0042] like image 3 As shown, the present embodiment includes: a test system connected to the substation network and a tested IED device, wherein: the network communication module in the test system reads the SCD file through the MMS network; the SCD analysis module uses the SCL tag search technology to analyze the SCD file The virtual terminal, virtual circuit, setting value (parameter), and function configuration of the tested IED device form the test items of the tested IED device; the test template module calls the preset standard test template, and matches the tested IED with the test item matching method. The test items of the device are compared to form the test case of the tested IED device; the test stimulus module realize...

Abstract

An intelligent transformer substation automatic testing system based on an SCD comprises a testing system and tested IEDs. The testing system and the tested IEDs are connected through a transformer substation network. The testing system generates a test case by analyzing an SCD file, a testing process is started through a human-machine interface, a simulation test excitation quantity is generated according to the test case, the excitation quantity is applied to the tested IEDs through a transformer substation local area network, the response of the tested IEDs to testing excitation is read, and finally a testing result evaluation report is automatically generated. The intelligent transformer substation automatic testing system based on the SCD can achieve the automatic evaluation of the testing result of each tested IED and achieve the complete management on the testing files of the tested IEDs, ensures the safe operation of a power grid, and improves the reliability of the power supply of a power system.

Description

technical field [0001] The invention relates to a test system in the technical field of intelligent substations, in particular to an SCD-based automatic test system for intelligent substations. Background technique [0002] With economic development, social progress, continuous improvement of technology and information technology, and global resource and environmental issues becoming increasingly prominent, the development of power grids is facing new issues and challenges. Relying on modern information, communication and control technologies, actively developing smart grids and meeting the requirements of sustainable development in the future has become a realistic choice for international power development. As an important support for smart grid construction, intelligent substations have made active attempts to adapt to the substation EPC project general contract construction mode and localized layout schemes. The goal of smart substations is based on the information colle...
