Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
Fig. 1 is a main process flow diagram of comprehensively protecting method for electrically according to the embodiment of the invention.
Referring to shown in Figure 1, comprehensively protect method for electrically and comprise: step S20: confirm the Very Important Person of needs guarantor electricity, generate the bus load export plan of each Very Important Person;
Step S40: calculate the radius of electricity supply of the distribution wire at each Very Important Person place, the radius of electricity supply that surpasses predetermined length is generated reduction scheme; And
Step S60: carry out export plan and reduction scheme, and according to the predetermined power supply situation of protecting electric user of execution result monitoring in real time.
Very Important Person and power supply situation thereof according to above-mentioned steps is protected electricity with each needs are carried out the combing analysis; Automatically analysis provides with the bus export plan and dwindles the radius of electricity supply scheme, when accident appears in circuit, can analyze the guarantor electricity client and the auto-associating emergency preplan of accident impact automatically.The bus export plan is meant client's power supply buses loaded and derive analyzes, and makes circuit and the bus export plan that satisfies the place, makes the load of Very Important Person further reduce, and failure risk further descends.Dwindle the radius of electricity supply scheme and be meant the radius of electricity supply of Very Important Person is dwindled, it is that pole line radius of electricity supply with the Very Important Person place reduces that this radius of electricity supply is dwindled the algorithm fundamental purpose, has so just reduced the probability that has an accident.
Fig. 2 derives algorithm flow chart according to the load of the power supply buses in the embodiment of the invention.
Preferably, referring to shown in Figure 2, concrete power supply buses load is derived algorithm and is comprised: step 201, definite as required Very Important Person that needs to protect electricity; Then, step 202 is calculated to each client: step 203, the distribution wire and the 10KV bus that find the client to supply power as follows; Step 204:, handle as follows successively to removing on this bus to all pole lines outside the pole line of client's power supply: step 205, judge whether this distribution wire is with Very Important Person, if this distribution wire can not be derived, finish the derivation of this distribution line; If not, setting up procedure 207, find out and this distribution wire have communication relationship distribution wire and handle as follows successively: step 208, judge whether this distribution wire is with Very Important Person; If finish this circuit export plan, if not; Carry out step 210, find the affiliated 10KV bus of this distribution wire, and carry out step 211; Judge whether this bus and above-mentioned bus are the bus under the same transformer, if, loop ends.If not, carry out step 213, judge on all distribution wires of this bus whether be with Very Important Person, if; Loop ends if not, carry out step 215, judges that can the load capacity of distribution wire satisfy the requirement of commentaries on classics band; And under the situation that is, carry out step 217, generate export plan.
It is that the pole line load of the 10KV bus under the Very Important Person is derived that the power supply buses load of Very Important Person is derived the algorithm fundamental purpose; Because the probability that has an accident of pole line is higher; Can cause flashing of busbar voltage during the appearance accident, the voltage of Very Important Person is impacted.Derivation is following with the principle of bus-bar frame ceases to be busy: the derivation circuit is a pole line; Change the circuit of band and must not be with Very Important Person; The capacity that changes the circuit of band can meet the demands; Change all outlets of the bus of band circuit and be not with Very Important Person; Changeing the bus of band circuit and the bus at Very Important Person place can not be the bus under the same transformer.
Fig. 3 is at the process flow diagram that dwindles algorithm according to the radius of electricity supply in the embodiment of the invention.
Preferably, referring to shown in Figure 3, calculate the radius of electricity supply of first distribution wire, first distribution wire that radius of electricity supply is surpassed predetermined length carries out radius of electricity supply to be dwindled.
Preferably, step 301 confirms to need to protect electric Very Important Person as required; Step 302; Calculate the radius of electricity supply that each client belongs to distribution wire; Circuit to surpassing designated length carries out following calculating successively: step 303, find all switches of Very Important Person place conducting line segment load side, and analyze the service area of above-mentioned switch from the near to the remote according to topological order; Find the switch that to derive load, and generate said radius of electricity supply reduction scheme; Step 304, the service area that calculates assigned switch supplies the interval as changeing; Step 305, find out and this commentaries on classics confession scope has the distribution wire of communication relationship to handle as follows successively: step 306, judge whether this distribution wire has Very Important Person; If not, carry out step 308, find the affiliated 10KV bus of this distribution wire; And carry out step 309; Whether this bus and client's bus belongs to the bus of same transformer, and under the situation of denying, carry out step 311, judges on all distribution wires of this bus whether have Very Important Person; And under the situation of denying, carry out step 313, and judge that can the load capacity of distribution wire satisfy the requirement of commentaries on classics band, and under the situation that is, carry out step 315, generate this radius of electricity supply reduction scheme.
It is with the pole line radius of electricity supply minimizing at Very Important Person place that the radius of electricity supply of Very Important Person is dwindled the algorithm fundamental purpose, has so just reduced the probability that has an accident.The calculating principle is following: the circuit that need reduce radius of electricity supply is a pole line; Change the circuit of band and must not be with Very Important Person; The capacity that changes the circuit of band can meet the demands; Change all outlets of the bus of band circuit and be not with Very Important Person; Changeing the bus of band circuit and the bus at Very Important Person place can not be the bus under the same transformer; Change the descending calculating of scope of band.
Fig. 4 is the processing flow chart when breaking down according to the supply line in the embodiment of the invention.
Preferably, referring to shown in Figure 4, step S60 comprises: the failure message according to the supply line that monitors is transferred emergency preplan; Emergency preplan is sent to remote mobile terminal automatically, and the repairing progress of portable terminal feedback is sent to the predetermined electric user of guarantor.
Fig. 5 is the snapshot of deriving the result according to the load of the power supply buses in the embodiment of the invention.
