2, the network state that power loss, other power supply turn confession is built.During 3 power supply difference dead electricity, in other two power supply turning solutions, select the network reconfiguration scheme of economy optimum, one can be selected to turn power supply source and power, 2 also can be selected simultaneously to turn power supply source and power.Wherein power supply one dead electricity, by the network state of power supply three turns of confessions is: the on off state of outlet switch 1, interconnection switch 1, interconnection switch 3 14 is point state; The on off state of outlet switch 22, outlet switch 33, block switch 1, block switch 24, block switch 35, block switch 4 13, block switch 5 10, block switch 69, block switch 7 11, block switch 8 12, block switch 9 15, block switch 10, block switch 11, interconnection switch 26 is conjunction state.Power supply two dead electricity, the network state being turned confession by power supply one and power supply San Tong method is: the on off state of outlet switch 22, block switch 5 10, interconnection switch 26 is point state; The on off state of outlet switch 1, outlet switch 33, block switch 1, block switch 24, block switch 35, block switch 4 13, block switch 69, block switch 7 11, block switch 8 12, block switch 9 15, block switch 10, block switch 11, interconnection switch 1, interconnection switch 3 14 is conjunction state.
3, each section of line failure after constructing wiretap, one or more power supply is needed to turn the network state of confession.
(1) feeder line sectional area break down, need 1 to turn network state that power supply source is island with power.During as line failure between block switch 24 and block switch 35, control is needed to close interconnection switch 26, by power supply three for being isolated island with power.Concrete network state is: the on off state of block switch 24, block switch 35, interconnection switch 1, interconnection switch 3 14 is point state; The on off state of outlet switch 1, outlet switch 22, outlet switch 33, block switch 1, block switch 4 13, block switch 5 10, block switch 69, block switch 7 11, block switch 8 12, block switch 9 15, block switch 10, block switch 11, interconnection switch 26 is conjunction state.
(2) feeder line sectional area break down, need 2 to turn network state that power supply source is island with power.As the line failure between outlet switch 1, block switch 24, block switch 1, point outlet switch 1, block switch 24, block switch 1 should be controlled, interconnection switch 1, interconnection switch 26 are closed in control, respectively by power supply two and power supply three for being isolated island with power.Concrete network state is: the on off state of outlet switch 1, block switch 24, block switch 1, interconnection switch 3 14 is point state; The on off state of outlet switch 22, outlet switch 33, block switch 35, block switch 4 13, block switch 5 10, block switch 69, block switch 7 11, block switch 8 12, block switch 9 15, block switch 10, block switch 11, interconnection switch 1, interconnection switch 26 is conjunction state.
4, when structure radial line (branch line) breaks down, the network state of Fault Isolation need only be carried out.Downstream line as block switch 8 12 breaks down, need control point block switch 8 12, concrete network state is: the on off state of outlet switch 1, outlet switch 22, outlet switch 33, block switch 1, block switch 24, block switch 35, block switch 4 13, block switch 5 10, block switch 69, block switch 7 11, block switch 9 15, block switch 10, block switch 11 is conjunction state; The on off state of interconnection switch 1, interconnection switch 26, interconnection switch 3 14, block switch 8 12 is a point state.As the line failure between block switch 7 11 and block switch 8 12, point block switch 7 11 and block switch 8 12 need be controlled, without the need to carrying out network reconfiguration.
When 5, building the interruption of certain Switch Communication, need the network state judging this on off state according to adjacent switch information.If communication disruption switch upstream and detection power direction, downstream switches place are consistent, then the state of this switch is conjunction state; Otherwise, be a point state.During as block switch 7 11 communication disruption, need the power direction detected by block switch 5 10 and block switch 8 12 place to judge its on off state, if two detection power directions, switch place are consistent, then block switch 7 11 should be conjunction state; For another example during interconnection switch one 8 communication disruption, the power direction that should be detected by block switch 1 and block switch 69 place judges its on off state, if two detection power directions, switch place are contrary, then interconnection switch 1 is a point state.
When 6, building the wrong report of non-most end switch place and fail to report fault message, need to judge according to the fault message at adjacent switch place the network state whether this switch place has fault current to flow through.If upstream and downstream switches place all detect fault current, then this switch place also should detect fault current.During as block switch 8 12 downstream fault, if block switch 5 10 and block switch 8 12 place have all reported fault current to flow through, and fault message is failed to report at block switch 7 11 place, so judgement block switch 7 11 also should have fault current to flow through by fault location and network reconfiguration system, thus correct isolated fault.
When 7, building generation breaker overstep tripping, need the network state correctly judging fault section according to all on off states and fault message.Criterion is by track sections all topological structure traverses network from mains side to outlet direction, the section be only connected with a breaker flowing through fault current is fault section, if the breaker of what fault section was connected flow through fault current does not trip, and the upstream circuit breaker tripping operation of affiliated same outlet, then prove that this trip breaker is overstep tripping, this overstep tripping breaker control should be closed when restoring electricity.During as line failure between block switch 7 11 and block switch 8 12, if there is overstep tripping in block switch 5 10, now outlet switch 22, block switch 5 10, block switch 7 11 all have fault current to flow through, so fault section should be judged as between block switch 7 11 and block switch 8 12, these two switch controls should divide by Fault Isolation, restore electricity block switch 5 10 to be controlled to close.
When 8, building validation switch tripping, the network state of standby isolation or standby recombination function.In fault isolation stage, if the switch failure of fault upstream, then travel through the adjacent all upstream switches of this switch and control point; If the switch failure of fault down stream, then travel through all downstreams control point that this switch is adjacent.In the network reconfiguration stage, if desired control the switch failure of conjunction, then travel through the connected all switches of corresponding dead electricity section, if can be powered by other power outlet, then relevant interconnection switch is closed in control.As the line failure between block switch 7 11 and block switch 8 12, in fault isolation stage, if block switch 7 11 is refused point, then need to start standby isolation features, control point block switch 69 and block switch 5 10, and incompatible restoring electricity is controlled to interconnection switch 1; If Fault Isolation success, namely block switch 7 11 and block switch 8 12 are controlled and are divided successfully, but close unsuccessfully in network reconfiguration stage block switch five (10) control, then should start standby recombination function, be restored electricity by interconnection switch 1.
