Description
Technical Field
The invention relates to the technical field of power system testing, in particular to a method and a system for testing transient homology comparison function of an intelligent recorder.
Background
The transient state homology comparison function of the intelligent recorder refers to that the intelligent recorder carries out homology data comparison and analysis on transient state analog quantity and switching value which are acquired by the intelligent recorder and are derived from the same primary equipment when faults occur.
For primary equipment such as a line, a transformer, a bus and the like, the intelligent recorder and the corresponding protection device acquire secondary voltage and current data of the primary equipment through different current transformers and secondary windings of the voltage transformers respectively; for the switch knife switch equipment, the intelligent recorder and the corresponding protection device collect the switch switching position through different auxiliary contacts; when primary equipment is subjected to fault disturbance, the intelligent recorder and the corresponding protection device record fault waveforms and generate respective wave recording files, and the wave recording files record instantaneous values of secondary fault voltage and current before and after the fault disturbance and position values of the switch knife switch. The intelligent recorder checks the consistency of fault disturbance data records of the intelligent recorder and the protection device by comparing the instantaneous values, the effective values and the change moments of the same switch positions of the analog quantities with the same intervals in fault wave recording files of the intelligent recorder and the protection device, so that the transient sampling performance of the voltage and current transformers and the action performance of the switch mechanism are checked.
At present, the verification of the transient state homology comparison function of the intelligent recorder is mainly realized in two modes, wherein the first mode is to conduct through-flow boosting on actual primary equipment, and the second mode is to apply fault quantity to a protection device and the intelligent recorder through two relay protection testers respectively. The primary side through flow boosting mode is closer to the real sampling environment, but the current and the voltage applied to the primary side can only be gradually increased in a slow adding mode in the test process due to the dangerousness and technical limitation of the through flow and the boosting test, so that fault disturbance cannot be really simulated. The two relay protection testers are adopted to apply fault quantity to the protection device and the intelligent recorder respectively, and the output synchronicity of the two relay protection testers is required to be kept strictly consistent, so that the two relay protection testers are required to be clocked simultaneously by clock synchronization equipment, and the two relay protection testers cannot be tested if the debugging site does not have clock synchronization conditions.
Therefore, the two test schemes are matched with the actual protection device for test, and the intelligent oscillograph can be debugged only by matching corresponding interval power failure for the engineering of additionally installing the intelligent oscillograph in the operation transformer substation, so that the economic benefit of the operation of the power grid is affected.
