Description
Technical field
The present invention relates to a kind of 110 kilovolts of system voltage allocation plans, particularly a kind of intelligent substation double bus schemes
The configuration mode of 110 kilovolts of system busbar voltage load equiblibrium mass distributions of mode.
Background technology
It is well known that double bus scheme mode busbar PT powers simultaneously to multiple interval multiple equipments, once it breaks down
Influence face is very big, deteriorated area protection seting cooperation, in some instances it may even be possible to cause power grid large number of equipment refused action or tripping of bypassing the immediate leadership.It is near several
Year, it puts into operation with intelligent substation Accelerating The Construction and constantly, combining unit and intelligent terminal are extensively using changing tradition change
Power station output, way of output research and development and design concept, and for 110 kilovolts of system lists of Intelligent transformer station double bus scheme mode
Equipment is configured, the mono- protections being configured of all 110kV of 220kV intelligent stations at present and automatic safety device are by I sections of busbares of 110kV
Combining unit cascade, which is drawn, takes busbar voltage, such as Fig. 1, shown in 2.DC power supply designs：110kV I, II sections of busbar combining units are straight
Galvanic electricity source is drawn respectively takes I, II sections of power supplys of DC power system, the protection of 110kV line segregations, observing and controlling, control and intelligent assembly electricity
Source carries out power distribution according to odd even interval numbers.General odd-numbered interval takes I sections of DC power supply, and even-numbered interval takes II
Section power supply.As shown in Figure 3.The bus bar configuration scheme of the prior art there are it is main the problem of have：1）110kVI sections of busbares merge single
Element device failure causes all 110kV line segregations voltages for cascading its busbar voltage to lose, distance protection and with directional element
Quick fraction zero-sequenceprotection be blocked, only retain long delay PT broken string overcurrent protection and zero-sequenceprotection（When generally adjusting action
Between be 3 ~ 4 seconds）, any circuit or element fault under this power system operating mode certainly will be got over caused by protection seting coordinates difficulty
Grade action, expands fault coverage, in some instances it may even be possible to a plurality of circuit be caused to trip simultaneously.2）Protection, the control at even-numbered interval
System and intelligent assembly are mounted with cascade busbar combining unit not on same section DC power supply, and DC power supply I segment faults lose feelings
Under condition, all 110kV route protections voltages lose, and the influence of generation is the same as 1）Analysis.
Invention content
It is an object of the invention in place of overcome the deficiencies in the prior art, and provide a kind of in current existing design scheme
On the basis of, it does not need to increase any equipment and material, by adjusting partly interval cascade optical cable circuit, modification interval relevant voltage
Virtual terminator is configured, so that it may avoid because I sections of busbar combining unit device fails lead to protection seting cooperation difficulty, any level
Join circuit or element failure under its busbar voltage and therefore cause action of bypassing the immediate leadership, expand fault coverage, in some instances it may even be possible to cause
A plurality of circuit trips simultaneously, the 110 kilovolts of system electricity of intelligent substation double bus scheme mode that is easier to improve and realize
Press configuration mode.

Line combining unit reconfiguration to II sections of busbar combining units export optical port, modification 110kV circuit even-numbereds interval combining unit grade
Join the virtual terminator configuration of control source：
When changing virtual terminator configuration, system integrator designs table, profit according to the modification virtual terminator that designing unit provides first
Use SCD（Whole station system configuration file Substation Configuration Description）Configuration file is to 110kV lines
The configuration of road even-numbered interval combining unit is modified, and deletes even-numbered line segregation combining unit to I sections of 110kV
The voltage SMV lines of busbar combining unit link even-numbered line segregation combining unit to II sections of busbares of 110kV and merge list
The voltage SMV lines of member, when SMV lines are configured, for recipient, it is necessary to first add external signal, then add internal signal.
It is as follows to add external signal configuration sequence：1）Select the physical address of SMV recipient；2）Selection SMV recipient corresponds to LD；3）Choosing
The LN where SMV lines is selected,；4）Select virtual terminator line Inputs options；5）Select external signal；6）By sending device
The FCDA that transmission data under SMV accessing points is concentrated is dragged to middle window, and discharge in order.Select internal signal configuration suitable
Sequence：In reception device, the LD-- under SMV accessing points》LN--》FC--》Under DO, corresponding DA is selected, is dragged to centre
Row in window where corresponding external signal completes the connection of external signal and internal signal namely completes a SMV company
Line completes the modification generation of SCD file configuration.
After modification generates above-mentioned SCD file, then line segregation equipment manufacturer is literary by SCD with the configuration tool of IED devices
CID files are generated after being extracted in part with this IED relevant informations, and passes through and specific IED equipment is attached under device configuration tool, i.e.,
Complete virtual terminator configuration.
It completes after being filled under above-mentioned configuration virtual terminator configuration and CID files, finally by I sections of busbar combining unit cascades of 110kV
