Platform and method for testing intelligent substation based on electromagnetic transient real-time simulation

Abstract

The application relates to a platform and a method for testing an intelligent substation based on electromagnetic transient real-time simulation. The platform comprises an intelligent substation real-time simulator and an intelligent signal conversion device; wherein the intelligent substation real-time simulator is used for simulating the operation scene of an actual secondary system of the intelligent substation in an electromagnetic transient simulation mode, providing a virtual operation environment for the actual secondary system of the tested intelligent substation and presetting commonpower grid faults; the intelligent signal conversion device is used for receiving data information generated by the intelligent substation real-time simulator in real time, performing format conversion, sending the converted data information to the actual secondary system of the tested intelligent substation, receiving response information of the actual secondary system of the tested intelligent substation to the preset power grid faults, and sending the response information to the intelligent substation real-time simulator to realize closed-loop test. The testing scheme of the platform and the method in the invention improve the confidence coefficient of simulation, improve the debugging depth and quality, and can verify a plurality of functions which cannot be verified in the past.

Description

technical field [0001] The application belongs to the technical field of intelligent substations, and in particular relates to an intelligent substation test platform based on electromagnetic transient real-time simulation. Background technique [0002] The development of substations in my country has generally gone through several stages: conventional substations, digital substations, smart substations, and a new generation of smart substations. In the initial stage of construction of conventional substations and even intelligent substations, their testing and analysis techniques are relatively simple, mainly relying on independent equipment such as relay protection testers, network packet analyzers, and network performance testers to conduct single-unit open-loop tests on equipment, and test The scale is small, which can only meet the simple function of testing a single device; the dynamic simulation test has a large investment, the test platform site is large, and the dom...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the existing technology, it is only simple to simulate the merging unit and the intelligent terminal data set to connect the intelligent secondary equipment, to verify the function of the equipment, and not to pay attention to the key events transmitted by the communication network of the whole station. As an effective test tool, it guides the construction, operation and maintenance of intelligent substations, thereby providing an intelligent substation test platform based on electromagnetic transient real-time simulation
