Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 , Ethernet communication has the characteristics of fast network speed, wide bandwidth, simple network structure, unified network equipment standards, and convenient interface with the test background computer, so that real-time access between nodes on the network becomes a reality. Each device in the automatic test system is connected through Ethernet, and the communication protocol uses the standard Q / GDW 131 and IEC61850 protocol, and is distinguished by the IP address of different devices. The automatic detection system realizes the time synchronization of the automatic automatic detection system through the time synchronization system, which can realize the operation monitoring of the test instruments and the equipment under test in the system under the unified GPS time reference, which improves the accuracy and reliability of AC ...

Abstract

The invention provides an automatic detection system and method of a synchronous phasor measurement device. The system comprises a test background server, a switch, a network tester, an OMICRON tester and a time synchronization system, wherein the network tester and the OMICRON tester both exchange data with the testing background server through the switch; the testing background server is communicated with the synchronous phasor measurement device through a network protocol; meanwhile time synchronization between the testing background server and the synchronous phasor measurement device as well as between the testing background server and the OMICRON tester is realized through the time synchronization system. Automatic generation of a test task, automatic execution of a detection step and automatic generation of a test report can be realized, so the interference of artificial elements is reduced, the testing randomness is removed, the testing efficiency and the testing reliability are improved, the repeatability of testing is realized, the traceability of the testing work is guaranteed, and the reliability and the consistency of a testing result are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automatic equipment testing, and in particular relates to an automatic detection system and method for a synchronized phasor measuring device. Background technique [0002] The synchronized phasor measurement device (Phasor Measurement Unit, PMU) can provide synchronized phasor data. The wide area monitoring system (Wide Area Measurement System, WAMS) based on the PMU measurement data measures the phasor information to monitor and analyze the dynamic process of the power system. An important basis for monitoring and control is an important part of the smart grid. Since the 1960s, when the developed countries in the world entered the era of large-scale power grid interconnection, large-scale blackouts have occurred frequently. The accident analysis report shows that the lack of effective dynamic safety monitoring means is one of the important reasons leading to previous large-scale blackouts. [0003] Sci...
