Description
Technical field
The present invention relates to the technical fields of electric system, more particularly, to a kind of system improving reclosing success rate and side
Method.
Background technology
In recent years, growing with social economy, client is higher and higher to electricity consumption reliability requirement, is set by improving
It standby stability and improves the modes such as power grid architecture and can improve the reliability of power supply, avoid that there is a phenomenon where substation power loss.
It is standby in order to improve reclosing and inlet wire but for having the 110kV substations of small power supply or 35kV substations
The motional success rate hauled oneself willingly into, a kind of universal way are using small power station's side installing voltage to frequency protective device, in electric system
Or it is main when sending power failure, small power station's side frequency declines, and (small water is isolated in low cycles unloading device action excision small power station
Electricity), but due to small power station's booting capacity is uncertain and automatic device is not perfect etc., small power station's side frequency can be caused to decline
Journey is longer, will not even decline, in this way, low cycles unloading device would not cut off small power station, is overlapped after leading to 110kV line faults
Lock is unsuccessful or prepared auto restart can not act, i.e., can not really improve the motional success rate of reclosing and inlet wire prepared auto restart.
Another way is when the tripping of 110kV line faults occurs, in local Lian Qie small power stations of 110kV substations special line
And have the 35kV substations power cord of small power supply, so as to cause one or two 35kV substation power loss, influence a township
The user power utilization in town or two small towns.Small hydropower resources abundant place, generally in 110kV substations, 35kV substations
Small power supply is carried out on 35kV busbares, 10kV busbares, a series of problems, such as this brings power supply reliability to reduce to substation.It is small
One evident characteristic of Hydropower Entering In Power Network be small power station distribution dispersion and also it is remote, cause the minimum operational mode of small power station to change
Greatly, it is difficult to determine the minimum operational mode of small power station to check protection sensitivity；Another feature be installed capacity it is small, secondly
Secondary protective device, automated system are not perfect, and power system operating mode variation is fast, usually become through 110kV substations, 35kV
The 35kV busbares in power station, the online power generation of 10kV busbares, part small power station surfs the Internet in 35kV substations, then passes through 35kV substations
Interconnection is surfed the Internet by 110kV substations, when in 110kV power transformation station owner's power transmissions source, line breaks down, in order to improve circuit overlap at
Power is largely to start linkage circuit in the main power transmission source route protection actions of 110kV, and connection is cut surfs the Internet in 110kV substations
Small power station's circuit (including the 35kV substations interconnection of small power supply), lead to the 35kV substation power loss, thus may be used
See, the power supply reliability of substation is influenced very greatly by small power station.This method can lead to one or two 35kV substation of statements based on collusion
Decompression causes power supply reliability low, influences user power utilization.Namely at present when the tripping of 110kV line faults occurs, to improve
Circuit re-switching success rate in 110kV substations local Lian Qie small power stations special line and can only have the 35kV substations of small power supply
Power cord, be easy to cause the 35kV substation power loss of small power supply, and network system operation stability is poor.
To sum up, the existing method for improving reclosing success rate can cause the power supply reliability of power grid low, network system fortune
The technical problem of row stability difference.
