Description
Technical Field
The invention relates to the technical field of power system testing, in particular to a method and a system for testing a transient state homology comparison function of an intelligent oscillograph.
Background
The transient state homologous comparison function of the intelligent wave recorder means that the intelligent wave recorder performs homologous data comparison analysis on transient state analog quantity and switching quantity of the intelligent wave recorder and the transient state analog quantity and the switching quantity of the same primary equipment when the fault occurs, wherein the transient state analog quantity and the switching quantity are collected by the protection device.
For primary equipment such as a line, a transformer, a bus and the like, the intelligent wave recorder and the corresponding protection device respectively acquire secondary voltage and current data of the primary equipment through different current transformers and voltage transformer secondary windings; for the switch knife switch equipment, the intelligent wave recorder and the corresponding protection device collect the switch on-off position through different auxiliary contacts; when primary equipment has fault disturbance, the intelligent wave recorder and the corresponding protection device can 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 a switch knife switch. The intelligent wave recorder checks the consistency of the fault disturbance data records of the intelligent wave recorder and the protection device by comparing the instantaneous values, the effective values and the change moments of the same switch knife-switch positions of the same interval, the same phase and the same analog quantity in the fault wave recording files of the intelligent wave recorder and the protection device before and after fault disturbance, so that the voltage and current transformer transient sampling performance and the switch knife-switch mechanism action performance can be checked.
At present, verification of the transient state homology comparison function of the intelligent oscillograph is mainly realized through two modes, the first mode is through-flow boosting of actual primary equipment, and the second mode is that fault quantities are applied to a protection device and the intelligent oscillograph through two relay protection testers. The mode of primary side through-current boosting is closer to a real sampling environment, but due to the dangerousness and technical limitation of through-current and boosting tests, the current and voltage applied to the primary side can only be gradually increased in a slow adding mode in the test process, and fault disturbance cannot be truly simulated. And the mode that two relay protection testers apply fault amount on the protection device and the intelligent wave recorder respectively is adopted, the output synchronicity of the two relay protection testers is required to be kept strictly consistent, so that the time synchronization equipment is required to simultaneously time synchronize the two relay protection testers, and the test cannot be carried out if the time synchronization condition is not set in a debugging field.
Therefore, the two test schemes need to be matched with an actual protection device for testing, and the intelligent wave recorder can be debugged only by matching the corresponding interval power failure in the engineering of operating the transformer substation additionally provided with the intelligent wave recorder, so that the economic benefit of power grid operation is influenced.
