Embodiment Construction

[0022] The technical effects of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Embodiment of Field Test System for Secondary Circuit in Intelligent Substation of the Present Invention

[0024] The on-site test system for the secondary circuit in the smart substation of this embodiment includes a maintenance test center and at least one test terminal connected to the maintenance test center; The test equipment sends analog or digital signals, and collects the exit node information of the secondary circuit to be tested; the maintenance test center is used to set the test data of each test terminal, and sends it to each test terminal, and receives the secondary circuit to be tested. The test feedback data of the equipment and the MMS information of the protection device are used to judge the correctness of the equipment under test of the secondary circuit according to the test feedback data and MMS informati...

Abstract

The invention relates to a system and a method for testing a secondary circuit on site in an intelligent substation. The system comprises an overhauling and testing center and at least one test terminal which is in communication connection with the overhauling and testing center, and is characterized in that the test terminal is close to equipment to be tested, and used for sending analog or digital signals to the equipment to be tested and acquiring outlet node information of the equipment to be tested; the overhauling and testing center is used for configuring test data of each test terminal, sending the test data to each test terminal and judging the correctness of the equipment to be tested according to test feedback data of the equipment to be tested and MMS (Manufacturing Message Specification) information. The test system can realize that the test personnel perform dosage on equipment to be tested, which are dispersively arranged in a switch factory, in a control room of the substation, whether protection response is correct or not is checked at a protection device end, and the correctness of station control level information on an MMS message monitoring device is analyzed, thereby forming closed-loop testing, and realizing a complete test for the secondary circuit of the intelligent substation. The system and the method provided by the invention improve the test efficiency and reduce the test cost.

Description

technical field [0001] The invention belongs to the technical field of electric power system substation testing, and in particular relates to an on-site testing system and method for a secondary circuit in an intelligent substation. Background technique [0002] According to the secondary equipment configuration plan of "General Design 110(66)-750kV Smart Substation Part of State Grid Corporation of Power Transmission and Transformation Engineering", at the smart substation site, it is more common that there is a long distance between the process layer equipment and the bay layer equipment. For substations with a voltage level of 330kV and above, the secondary equipment is equipped with an on-site relay protection cell according to the principle of relative concentration and local dispersal, which is used to install and arrange the secondary equipment on the corresponding interval layer, while the process layer such as intelligent terminals and merging units The equipment is...
