Description
Technical field
The present invention relates to a kind of aerial power transmission line on-line monitoring system and method, mainly be applicable to the on-line monitoring and the fault diagnosis of aerial power transmission line aeolian vibration, conductor temperature, angle of wind deflection in the electric system, belong to the electric power monitoring technical field.
Background technology
Aerial power transmission line is UHV (ultra-high voltage), remote, jumbo power transmission sequence particularly, in operational process, be subjected to the influence of meteorological condition and external environment etc. that the aeolian vibration that allows amplitude often takes place to surpass, often cause the fatigue breakdown of some circuit parts, as disconnected strand of the fatigue of lead wire and earth wire, the fatigue breakdown of gold utensil, conductor spacer and shaft tower member or wearing and tearing etc.Wherein lead wire and earth wire is the problem that aerial power transmission line generally takes place for tired disconnected strand, all fronts road need be replaced by new lead when serious.The safe operation that China's electrical network aerial power transmission line comprises big leap in aeolian vibration serious threat at present.
Aeolian vibration causes that accident such as the tired disconnected thigh of lead wire and earth wire is that mode by cumulative effect takes place, an accumulated time and process are arranged, lead wire and earth wire is difficult to during vibration observe with the naked eye, in case after finding that anti rattler damages or comes off, just may compare seriously because of the disconnected thigh that fatigue causes.And before this, its harm is often subtle, and these faults are difficult to effectively prevent by traditional artificial line walking means regularly.Press at present and use intelligentized data monitoring device that on-line monitoring and fault diagnosis are carried out in the power transmission sequence aeolian vibration, scent a hidden danger early, in time fix a breakdown, to improve the power transmission sequence reliability of operation.In addition to the on-line monitoring of line temperature to improving the transmission capacity of lead, reduce track investment, the situation of alleviating China's power supply situation anxiety also has very big reference significance.The monitoring of angle of wind deflection is to the aerial power transmission line safe operation, and especially safe operation under special meteorological condition and improvement design provide important references.
Traditional method is regular detection.When a certain power transmission sequence is carried out periodic measurement, before measuring beginning, must be installed to instrument on the lead wire and earth wire by the hot line job personnel at every turn, also must remove after measure finishing, installing at every turn or remove must hot line job, and it is all multifactor to relate to job safety etc.After measuring end, only in the laboratory, just can carry out data processing and analysis.Even to telemetering gear, sensor and transmitter can only be fixed on the suspension clamp, and receiver and pen recorder are placed in ground trailer or the house, adopt magnetic recording, also must wait and to handle and to analyze by computing machine after returning the laboratory, draw measurement result.This vibration measuring instrument implements the comparison difficulty, and because of the vibration measuring instrument uses powered battery, in-site measurement limited time, particularly measurement result representativeness sometimes are not high, lack real-time.Above reason causes the measuring method of present use and vialog utensil that certain limitation is arranged.
