Abstract

The invention discloses a testing and verifying system appropriate for an intelligent transformer substation and a verifying method. The system comprises an upper computer and an embedded system lower computer that comprises a collecting plate, a signal plate, a data plate and four sub-plates of a synchronization plate. The signal plate, the data plate and the synchronization plate are supplied with power by an external adapter DC5V. The synchronization plate provides synchronization pulse signals to other sub-plates. Ethernet of the upper computer is connected with the signal plate of the upper computer, the intelligent transformer substation, and a process layer, an interval layer and a station layer network of a digital transformer substation by an RJ45 twisted-pair through an industrial switchboard. The testing and verifying system appropriate for the intelligent transformer substation is convenient to detect and verify the electrical capacity of current intelligent transformer substation and digital transformer substation and improves the debugging speed of the intelligent transformer substation and digital transformer substation greatly so as to provide good technical assurance to construction of the intelligent transformer substation and digital transformer substation and lay a solid foundation for safe and stable operation of the intelligent transformer substation and digital transformer substation.

Description

technical field [0001] The invention relates to a test and calibration system and calibration method suitable for intelligent substations, which are used for system-level on-site testing and calibration of electronic transformers, merging units, protection measurement and control devices, intelligent switches, and electric energy meters in intelligent substations and digital substations. It belongs to the technical field of power system intelligent substation and digital substation detection / calibration. Background technique [0002] Smart substation is an indispensable part of smart grid construction. In 2009, the formulation of a series of technical standards for digital substations by the State Grid Corporation of China marked that the construction of digital substations has moved from the stage of scientific and technological projects to the stage of engineering practice. With the large-scale application of electronic transformers, merging units, intelligent switches, e...
