Description

An assembly line detection system for in-situ relay protection device

technical field

The invention belongs to the technical field of electric power detection, and in particular relates to an assembly line detection system for an in-situ relay protection device.

Background technique

The in-situ relay protection device is installed near the primary equipment, the liquid crystal interface is canceled, and the standard connector is used externally. The test method is different from the conventional protection. It is difficult to carry out the on-site test work, and a large amount of test work needs to be carried out in the factory. At present, the following outstanding problems need to be solved in the detection of in-situ relay protection devices.

(1) In-situ protection has not yet formed a mature standardized detection system

There are many differences between in-situ secondary equipment and traditional relay protection equipment. One is to cancel the LCD panel design of the in-situ protection device, and it is necessary to combine the MMS, GOOSE information and protection management unit information of the device to carry out testing work. Compared with the field, the testing work is more suitable for carrying out in the laboratory or factory; The interface form of the in-situ relay protection device has changed, and the traditional relay protection test mode and test instruments are no longer applicable; third, the detection content, detection process and detection mode of the in-situ protection device are still being explored and have not yet been formed. Standardized detection system. These are the difficulties faced by in-situ protection testing.

(2) Lack of actual operation data of substations to carry out real scene verification of in-situ protection

At present, the relay protection test method is still mainly through a relatively independent test device, simulating sampling and primary equipment signals, and carrying out the verification of the performance of a single device and simple switch-in and switch-out, and there is no test that simulates the operation data of the whole station at the same time. The testing capability does not have the hardware-in-the-loop simulation at the device function level, and it is impossible to carry out system-level testing between devices, and it is difficult to realize on-site plug-and-play of devices. After the equipment is sent to the site, a lot of systematic verification work still needs to be carried out. On the one hand, the workload is heavy. On the other hand, it also brings security risks. In addition, the on-site protection work requires the main detection work of the relay protection device to be carried out in the laboratory or factory in advance, but the laboratory or factory lacks the actual operation data of the substation, and it is impossible to carry out the actual scene verification of the on-site protection, and it is impossible to realize the secondary protection. Equipment level simulation and dynamic model level simulation.

(3) Conventional detection methods for relay protection cannot meet the large-scale detection requirements of factories

At present, the routine detection of relay protection still stays in the stage of carrying out the test and detection work by applying excitation and observing the response after man-made operations such as test configuration and device wiring. This mode relies heavily on professionals and test equipment, and the workload is heavy. It is difficult to meet the actual needs of large-scale testing of protective devices in laboratories or factories. At the same time, the limitation of the verification means, the incompleteness of the verification content and the subjective judgment of the verification results lead to differences in the evaluation standards and test results of the test, and also lay hidden dangers for the safe and stable operation of the relay protection equipment. How to use the advantages of in-situ protection interface, size, and information exchange standardization to form a new pipeline detection mode to meet the needs of large-scale detection is a difficult problem in the development of in-situ protection work.
