The present invention is further illustrated below in conjunction with Fig. 5.
First switch segments is described:
The present invention is resolved into a plurality of electric indivisible unit with power distribution network, it is switch segments, linking to each other by switch between switch segments further forms electric isolated area, and the zone that links to each other with the gate out switch of the 10kv bus of electric substation is charging zone, and a charging zone is exactly a circuit.
At first will be on the less equipment of analysis result impact, tiny branch road, the length of feeder line, the factors such as parameter of impedance are temporarily ignored, thereby form the simplified model of 10kv distribution; The distribution simplified model is decomposed into the unit that several can not be cut apart by switch, and these unit are defined by one group of switch, wherein comprise some circuits, and such unit is called " switch segments ".Elliptical region among Fig. 5 is switch segments, and distribution simplified model network equipment element only has bus, switch, circuit, and wherein #5 switch, #7 switch, #12 switch, #19 switch are block switches.
Again power supply area is described:
A plurality of switch segments compositing area that can link together, these zones electric be not identical, be called " electric isolated area ", two kinds of zones are arranged: charged with uncharged, must have a switch segments to link to each other with a bus in the charging zone, the switch that links to each other with bus in the charging zone is called the power switch in zone.The switch segments that does not link to each other with bus in the territory, neutral area.Can only have a switch segments in the zone.Adjacent area refers to have respectively in two zones a switch segments, and these two switch segments are adjacent, and switch common between them is in " dividing " state.The rectangle shadow region is the zone among Fig. 5, has 5 zones.
Parameter initialization: initialization static network topology parameter.From database, read network configuration parameters, comprise bus, switchgear, feeder line parameter and equipment connection parameter, and generate the static topology of distribution according to parameter.
Switch segments generates: the static topology connection parameter according to configuration generates switch segments, comprises the boundary switch of switch segments, and preserves switch segments information.Adopt Depth Priority Algorithm, from each bus, determine the power switch of switch segments.Switch segments among Fig. 5 sees Table 1:

Charging zone generates: take each bus as starting point, obtain the actual switch state from real-time data base, calculate the switch segments that can be communicated with power source bus.These switch segments form charging zone, are this block supply switch with the switch that bus directly links to each other.And preservation charging zone information.Zone among Fig. 5 sees Table 2:
The territory, neutral area generates: convenient all uncharged switch segments if the on off state that links to each other is " closing ", then belong to territory, a neutral area.Final uncharged switch segments also will form territory, some neutral areas.And preservation charging zone information.Zone among Fig. 5 sees Table 2:

When electric isolated area division module was operated on off state and becomes " divide " variation from " closing ", its process was:
1) precondition: initialization is correctly finished, and the switch of state variation is the band electric switch.Take Fig. 5 as example, suppose that the #14 switch disconnects.
2) create new region: increase a new zone, take the switch of state variation as starting point, this switch must be the power switch of certain switch segments, and the switch segments of being powered take this switch is moved into new zone with coupled logical switch segments respectively as direction.Take Fig. 5 as example, a newly-built zone 6, take the #14 switch as power switch is switch segments 17, and switch segments 17 and the switch segments 18 that is connected with switch segments 17 are moved into zone 6.Zone 6 is uncharged.
3) the special sight that disconnects of the power switch of processing region: if the switch of the state variation regional power switch that is exactly this, then directly with this zone marker for not charged, need not other processing.
When electric isolated area merged module and is operated on off state and becomes " closing " variation from " divide ", its process was:
1) precondition: initialization is correctly finished, and the switch of state variation is the band electric switch.Take Fig. 2 as example, suppose that the #7 switch closes.
2) seek the zone that links to each other: according to two zones that the switch segments of owning this switch together finds this switch to belong to, one of them is charging zone, and another is the territory, neutral area.Take Fig. 5 as example, suppose that the #7 switch closes, two switch segments under the #7 switch are respectively No. 6, No. 7 switch segments, these two switch segments are affiliated area 2 and zone 3 respectively.
3) zone merges: charging zone does not need to do any processing, with switch segments all in the uncharged zone and in charging zone, deletes this territory, neutral area.Take Fig. 5 as example, regional 3 charged needs processed, and zone 2 is not charged, and the switch segments 6 and 7 in the zone 2 is joined respectively in the zone 3, deletes zone 2.
4) determine the power switch of the switch segments newly incorporate into: take the switch of state variation as starting point, towards the power switch of each switch segments of orientation determination of the switch segments of newly incorporating into.Take Fig. 5 as example, take the #7 switch as starting point, adopt Depth Priority Algorithm, determine respectively switch segments 6 in former regional 2 and 7 power switch.
When having many on off states to change, in order to prevent from occurring in the computational process situation of network closed loop, process to divide first to be combined into afterwards sequentially.For each by " closing " to " divide " and switch, call respectively electric isolated area division module; Again for each by " dividing " switch to " closing ", call respectively electric isolated area and merge module.
In sum, the present invention adopts the layering computation schema, power distribution network is divided into the distribution transforming layer, switch segments layer and 10kv line layer, when distribution 10kv line switching state changes, variation is ensued in the switch segments combination of line layer, in next computing cycle, the variation of circuit can be reflected in the calculating of circuit line loss in time, eliminated the change of distribution line operational mode and supply district to the impact of result of calculation, improved the accuracy that 10kv circuit line loss is calculated, and by reducing 10kv circuit line loss computing cycle, improved the instantaneity that 10kv circuit line loss is calculated.
