Description
Technical field
The invention belongs to route protection technical field, specifically a kind of ultra-high-tension power transmission line protects component.
Background technique
The electricity that power plant issues not is to use only for neighbouring people, to be also transferred to far place, is met more
Needs.Often one end respectively joins in connection with a high-power station, the other end in connection with a load center or both ends transmission line of electricity
It is a large power system.These electricity then cannot be transferred out directly by common electric wire, but use high voltage transmission line
Road transmission, commonly referred to as 220 kilovolts of transmission voltages below are called high voltage power transmission.It is defeated as power system capacity increases sharply
The advantages of the advantages of electric line is increasing, ultra-high-tension power transmission line just shows, ultra-high-tension power transmission line be, high voltage power transmission
It is a kind of mode that will be transmitted after boost in voltage that generator exports by power generation house transformer.Why in this way
Transmission of electricity is because in the case where same transmission power, and voltage gets over high current with regard to smaller, when such high voltage power transmission just can be reduced transmission of electricity
Electric current to reduce the thermal losses generated by electric current and reduce the material cost of long distance power transmission, when the electric ground for being transported to electricity consumption
Fang Hou can be used as long as voltage drop is lowly come.Since route is long, transmission power is big, so maintaining the safety of transmission line of electricity
Stable operation is a particularly significant problem.Therefore the protection of ultra-high-tension power transmission line is most important, to industrial and agricultural production, hands over
Logical, transport, national defence and daily production and living have very important significance, to ensure extra high voltage network safety and stability
Operation prevents failure from causing the fire incident that may occur, causes serious consequence, can especially send out in the case where some are special
The case where raw over-voltage protection element is burnt, causes second accident, and the safe and stable operation of ultra-high-tension power transmission line is transported in the system failure
Row requires transmission line of electricity main protection reliably can quickly cut off the failure that route occurs for the first time, is very important.
Currently, also occur a kind of some ultra-high-tension power transmission line protection technique schemes in the prior art, such as application No. is
A Chinese patent of CN201810018052X discloses a kind of ultra-high-tension power transmission line protection component, comprising: analog channel processing
Unit, analog acquisition unit and central processing unit, the analog channel processing unit include interconnection and vertical passage, institute
Interconnection is stated for providing the number of this side of current line and this side of adjacent lines and current line opposite side and adjacent lines opposite side
According to interaction channel, the vertical passage is for providing the data exchange channels of current line this side and current line opposite side；It is described
Analog acquisition unit is used to acquire the voltage and current analog data of this side of current line, and by collected current line
The voltage and current analog data of this side is sent out after processing obtains the voltage and current digital quantities of this side of current line
It send to the central processing unit；The central processing unit is used to receive the voltage and current digital quantities of this side of current line,
The voltage and current digital quantities of current line opposite side are obtained by the vertical passage, and phase is obtained by the interconnection
The voltage and current digital quantities of this side of adjacent line road and adjacent lines opposite side, and by the voltage and electricity of the two sides of the current line of acquisition
The voltage and current digital quantities of the two sides of streaming digital amount and adjacent lines carry out accident analysis by six-sequence component method algorithm
Fault localization is obtained as a result, passing through the range accuracy for improving route, to realize the protection to route.
The technical solution can be realized the range accuracy for improving route, and then improves transmission line malfunction analysis and obtain event
Hinder distance measurement result；But the security risk occurred in route can not handle in time and can not accomplish to cut off the power immediately, will lead
Ultra-high-tension power transmission line accident is caused to occur；The raising of the range accuracy of ultra-high-tension power transmission line is not accomplished timely to route event
Hinder the prevention occurred.
