Description
[technical field]
The present invention relates to power equipment running technology field, particularly relate to a kind of 110KV double back paired running circuit and overlap
Lock puts into method and puts into circuit.
[background technology]
At present, electrical network 110KV single supply paired running double-circuit line refers to by same transformer station same electric pressure bus
On two return back out line paired running band customer charge.
110KV single supply paired running double-circuit line reclosing investing method, circuit LI mains side chopper D1, circuit L2
Checkout voltage mode W thrown by mains side chopper D3 reclosing, and circuit LI load side chopper D2 reclosing throws non-synchronous mode F, line
Inspection synchronizing mode T thrown by road L2 load side chopper D4 reclosing, such as Fig. 1.
Circuit L1, circuit L2 paired running, when there is transient fault in circuit L1, circuit L2 simultaneously, circuit L1 power supply
Side chopper D1, circuit LI load side chopper D2, circuit L2 mains side chopper D3, circuit L2 load side chopper D4 protect
Action is tripped.Now, circuit LI mains side chopper D1 reclosing mode is checkout voltage mode W, after inspection circuit is without pressure, and chopper
D1 reclosing action, because line fault is transient fault, on circuit, fault eliminates, and circuit possesses power transmission condition, therefore circuit
LI mains side chopper D1 reclosing action success is normal to circuit L1 power transmission；Circuit L2 mains side chopper D3 reclosing side
Formula is checkout voltage mode W, and after inspection circuit is without pressure, chopper D3 reclosing action, because line fault is transient fault, on circuit
Fault eliminates, and circuit possesses power transmission condition, therefore circuit L2 mains side chopper D3 reclosing action is successful, to circuit L2 power transmission
Normally.Now circuit LI load side chopper D2 reclosing mode is non-synchronous mode F, now meets reclosing mode F action
Condition, chopper D2 should overlap, but other are unrelated with reclosing mode due to the mechanism of short-circuiting device D2 own or secondary connection etc.
Factor, cause chopper D2 unsuccessful reclosing, circuit LI load side chopper D2 is at open position, and circuit L1 is to load side
Bus M2 power transmission is unsuccessful, load side bus M2 no-voltage；And circuit L2 load side chopper D4 reclosing is inspection synchronizing mode
Can T, chopper D4 one of the key factor of successful reclosing depend on that circuit L2 has voltage and load side bus M2 to have voltage two
Individual condition, because of circuit L1 load side chopper D2 unsuccessful reclosing, load side bus M2 no-voltage, does not meets circuit L2 load side
Chopper D4 reclosing inspection synchronizing mode T coincidence condition, therefore chopper D4 reclosing action is unsuccessful, causes circuit L2 to load
Side bus M2 power transmission is unsuccessful, load side bus M2 still no-voltage, causes user to have a power failure, load loss, reduces power system
Power supply reliability.
