Abstract

The invention provides a detection system suitable for a relay protection device. The system comprises a man-machine interaction module, an I / O control module, a test tooling, a communication detection module, a static detection module and a dynamic simulation detection module. The modules are connected to an Ethernet communication bus. The man-machine interaction module sends a relay protection test case and a configuration file to the I / O control module, the communication detection module, the dynamic simulation detection module, and the static detection module. The I / O control module sendsan analog quantity and / or a switching value to a protection device to be tested, carries out dynamical and static detection on the relay protection device to be tested, and then sends protection displacement information to the communication detection module so as to carry out protocol consistency detection. A detection result is sent to the man-machine interaction module. In the invention, the detection requirement of the relay protection device is satisfied, the operation level of the relay protection device is increased, the reliability of the detection result is improved, and the multi-angle automatic detection of the full information coverage of the relay protection device is realized.

Description

technical field [0001] The invention belongs to the field of relay protection for power system substations, in particular to a detection system suitable for relay protection devices. Background technique [0002] In recent years, with the development of the power system, the reliability requirements of the hardware system of the microcomputer relay protection device are getting higher and higher. How to ensure the quality of the hardware system is an urgent problem that we need to solve. The relay protection device is the main component of the power system. The normal operation of the relay protection device directly affects the reliability and safety of the power system operation. Therefore, it is very important to ensure the normal operation of the relay protection device. It is particularly important to test the various functions of the device. [0003] At present, at home and abroad, the detection methods and angles of microcomputer protection devices in different stage...
