The fixed value adjusting method of power distribution network in electric system, as shown in figure 1, including step：
S11, the upstream-downstream relationship that each distribution management equipment room in power distribution network is determined according to the characteristic of electric current；
Because the distribution management equipment in power distribution network, the setting of its definite value will at its upstream and the definite value in downstream between, i.e. can not
More than the definite value in downstream, the definite value of higher level can not be less than, so when fixed value adjusting is carried out, it is necessary first in determining power distribution network
The upstream-downstream relationship of each distribution management equipment room.
S12, the upstream and downstream distribution management equipment for obtaining target distribution management equipment respectively by Ethernet or token-ring network
Definite value parameter；The target distribution management equipment is the distribution management equipment for carrying out fixed value adjusting；
In embodiments of the present invention, each distribution management equipment in power distribution network is in a network, the topology knot of network
Structure can be Ethernet, or token-ring network；The fixed value calculation of distribution management equipment be by the program of computing module from
Move what is completed, distribution management equipment can obtain the value data of the distribution management equipment of its upstream and downstream by network.
The embodiment of the present invention has different embodiments according to different application scenarios, for example, newly add when a certain
When entering the distribution management equipment of power distribution network and needing to carry out fixed value adjusting, because it is also newly to add Ethernet or token-ring network,
Cannot also correctly know the node address of its upper and lower downstream distribution management equipment（Such as, IP address）, at this point it is possible to pass through one
Line inspection device come obtain the node address of the distribution management equipment of its upstream and downstream, i.e. staff accessed by line inspection device treat into
The distribution management equipment of row fixed value adjusting, and by the distribution management equipment of the distribution management equipment upstream and downstream of pending fixed value adjusting
Node address send to the distribution management equipment of pending fixed value adjusting.Now, target distribution is obtained respectively by Ethernet
The detailed process of the definite value parameter of the upstream and downstream distribution management equipment of management equipment can be with as shown in Fig. 2 including step：
S21, target distribution management equipment obtain the upstream and downstream distribution of the target distribution management equipment by the line inspection device
The IP address of management equipment；
S22, access upstream and downstream distribution management equipment respectively according to IP address, and obtain definite value parameter.
In addition, when a certain distribution management equipment in network needs to re-start fixed value adjusting, due to the target
Distribution management equipment has learned that the node address of its upstream and downstream distribution management equipment, it is possible to access upstream and downstream distribution automatically
Management equipment, and definite value parameter is obtained to realize fixed value calculation.
In actual applications, required definite value parameter can include overload value, three section protection value and reclosing mode etc..
S13, using definite value parameter as reference parameter, the target distribution management equipment is carried out by default computing module
Fixed value calculation, obtain definite value result；

Typical computing formula can include in present invention enforcement：
Iact.1=krelIk.B.max, Iact.2=krelIk.C.max and Iact.3=krelIk.D.max
So, parameter is taken from upstream and downstream, afterwards the pattern by converting determines itself definite value, and is adjusted, it is ensured that Bu Huiyin
Management for circuit alternates and loses definite value, departs from protection.
Wherein, the Iact.1 be first paragraph immediate current quick-break value, Iact.2 be second segment immediate current quick-break value,
Iact.3 is the 3rd section of immediate current quick-break value；Iact is actuating of relay electric current, i.e. definite value target current, and krel is reliable system
Number, it is that three-phase is alternate short at B, C, D bus of protection zone end under maximum operational mode that general value is 1.2～1.3, IkBmax
Lu Shi, flows through the short circuit current of protection.
S14, target distribution management equipment realize fixed value adjusting according to the definite value result.
By computing module in the embodiment of the present invention, definite value result can be automatically generated, so target distribution management sets
It is standby just fixed value adjusting to be realized according to definite value result.
In sum, in the embodiment of the present invention, the distribution management equipment in power distribution network belongs to consolidated network（Ethernet or
It is token-ring network）, data communication can be carried out each other；Distribution management equipment in the embodiment of the present invention is additionally provided with computing
Reason system（Such as on-chip system）, the program of setting can be passed through（That is, computing module）Realize the calculation process of data；So, when
When carrying out fixed value adjusting to a certain distribution management equipment, the distribution management equipment can by network respectively at access thereon under
The distribution management equipment of trip, and obtain the value data of the two distribution management equipment；The definite value that needs are calculated is included
Various, the computing formula being related to also has multiple, by the design of program, required multiple computing formula can be packaged in into computing
In module；So, computing module just can enter with the value data in the distribution management equipment of the upstream and downstream for getting as parameter
Row fixed value calculation；It follows that passing through the embodiment of the present invention, it is possible to achieve obtain with reference to value data during fixed value adjusting
Automation and the automation of fixed value calculation, it is possible to efficiently reduce carry out the time cost of fixed value adjusting process and manpower into
This；And then also can just effectively improve the ageing of fixed value adjusting.
