And the intelligent billing module is connected with the output end of the contact diagram module and is used for simulating manual billing of the corresponding power outage and restoration instruction ticket according to the application form, the real-time distribution network operation mode, the commonly used terms and power outage and restoration logic which are input into the database in advance and the billing rule.
Furthermore, a first layer of the three layers is a transformer substation index diagram, a second layer of the three layers is a transformer substation internal wiring diagram, and a third layer of the three layers is a diagram dividing an electrical structure connected with a feeder according to an N-1 hand power into 494 Zhang Lianlao.
It should be noted that, in order to ensure the uniqueness of the devices, each device appears on only one contact diagram, when the standby switching device is encountered, there are two power connection points, and when the two power connection points belong to two different contact diagrams respectively, it is reasonable that the standby switching device is drawn on any one of the two contact diagrams, and the standby switching device is placed according to the graph friendliness in principle.
Furthermore, the 494 Zhang Lianlao map carries out the information recovery of the whole network map by adding the functions of jumping, marking and jumping of the same-pole erected line and special marking of the standby equipment;
jumping can be directly started and a contact diagram where another path of power supply boundary of the backup switching equipment is located is jumped;
it should be noted that this embodiment provides a preferred skip function specification, and the substation 35kv outlet switch: the 35kv feeder outlet switch will be displayed on two layers: in the substation internal wiring diagram and the contact diagram where the substation internal wiring diagram is located, automatic skipping can be achieved through the tool click switch with the 'thematic diagram hierarchical display'. Dual (multi) power user: the user of the double (multiple) power supplies can select the boundary pole number of the other power supply point by a 'thematic map hierarchical display' tool box except that the boundary pole number of the other power supply point is marked by a bright-colored mark under the user, and the user can also realize the jump to the contact map of the boundary of the other power supply of the user and highlight the contact map, so that a dispatcher can be helped to master the power supply condition of the other power supply of the double (multiple) power supplies, and particularly in the fault treatment of power failure of many line faults under severe weather such as typhoon, the important user is guaranteed to have at least one available power supply. The standby power supply equipment is the same as a dual-power supply user, a demarcation pole number for marking another power supply point is marked at the inlet wire cable head of another power supply, and a contact diagram where the demarcation of the other power supply of the standby power supply equipment is located can be directly started and jumped by utilizing a jump tool;
the mark of the same-pole erection line and the skip are added with a field in the professional standing book of each pole tower: whether the equipment is on the same pole; if so, filling in another field: several times of the same pole;
when the professional standing book indicates that the towers have the same-pole equipment, the same-pole identification appears on the line when the contact diagram is generated, and two loops and three loops of the same pole can be distinguished, and it should be noted that the lead between two towers of the ordinary overhead line is represented by a green solid line, the lead between two loops of the same pole is represented by a solid line and a dotted line, the lead between three loops of the same pole is represented by a middle solid line and an upper dotted line and a lower dotted line; meanwhile, the overhead lines on the same pole need to be jumped after being packed;
the special identification of the backup switching equipment is characterized in that a background of a backup switching station is filled with one color, and two incoming line switches which are backup switches are connected and marked with another color and line type.
As a preferred way, the background of the backup station is filled with grayish blue, and a note is written between the two incoming line switches that are backup to each other with a red dashed connection: and the standby power supply can clearly see which two switches are switched for standby power supply, and the station is the standby power supply station when the whole diagram is reduced. When the power point on the side of the standby power supply equipment which is getting power suddenly loses voltage, the standby power supply device can be automatically started to disconnect the incoming line switch on the original power supply side, and then the incoming line switch on the power supply on the other side is switched on, so that the standby power supply function is realized.
Further, the substation index map is used to distinguish the substation names by different colors for their voltage classes.
It should be noted that, as a preferred embodiment, 220kv may be in a red font, 110kv may be in a blue font, and 35kv is in a yellow font, which is very helpful for the new dispatcher to learn, when the new dispatcher is not familiar with the transformer class and the operation and maintenance unit to which the transformer class belongs, the new dispatcher may not need to look up a professional ledger of the transformer substation to find out which operation and maintenance the transformer class belongs to operate, and does not need to look up a protection rating list to determine the transformer class by the OMS system.
Furthermore, the substation in-station wiring diagram is used for generating a layer by electrically connecting all operating buses, bus couplers and all outgoing feeder switches of a substation, and the network property of the line is marked below each outgoing feeder switch.
It should be noted that the default is a hand-in-hand feeder, which is not particularly labeled; if only one power supply point exists, the circuits of a plurality of devices which are not connected with other power supply points are set as the radioactive marks; if the user only has the special line of the power supply is set as a single special mark; if the special line user has two or more power supply points, the corresponding marks are set as double special marks, triple special marks and the like.
The special function of this layer is:
1) When the CC2000 system prompts a fault indication that a certain bus has a loss of ground, a plurality of outgoing feeder lines on the bus can be seen immediately, and the network structure of each feeder line is the same;
2) When a main network power supply side fails to cause voltage loss of a certain substation semi-station or total station, the information such as the number of special line users, the affected power failure area, the affected load data and the like can be immediately counted;
3) The layer can perform statistics of information according to the bus, for example, statistics of how many important users (including the important users connected to each outgoing feeder) exist on the bus provides a good platform for planning work such as a configuration and modification plan, reliability statistics, risk early warning and the like. The layer can be used by not only a distribution network dispatcher, but also other planning departments, data statistics departments and even an electric charge class by adding some special tools, and has good expansibility.
Furthermore, the contact diagram module also comprises a one-key extraction trunk line graph which is used for extracting trunk line equipment, multiple power supply users and important users, generating a temporary trunk line graph by the extracted equipment according to the topological relation of the equipment, and displaying the temporary trunk line graph in a popup window mode.
Further, the DMS1000E module includes:
the database is used for storing the collected information and the state of the equipment;
it should be noted that, in the DMS1000E module, three boxes are provided below each device, and are used to display a three-phase current value passing through the device in real time and store the value in a database, all devices having remote measuring devices collect three-phase currents and device states on site through the distribution automation device and transmit the information to a remote database through an automation communication channel, and when each computer terminal opens a contact diagram, the system reads all devices on the contact diagram, and reads and displays real-time information and states of the devices from the database;
loop closing and opening detection is used for judging whether system loop closing operation is caused or not in the process of remote control operation;
if yes, automatically starting a loop closing and opening auditing program, wherein the program can automatically search two power supply points of loop closing equipment which can cause loop closing, extract real-time loads through a database, calculate the loads of the power supply points after loop closing operation, compare the loads with the maximum allowable loads of the two power supply points, give a popup window prompt if the calculated loop closing load is greater than the maximum allowable load, and otherwise, directly call a remote control execution program;
the three remote technologies comprise remote measurement, remote signaling and remote control technologies.
The remote measurement means that after the field equipment is provided with the automatic remote control device, the current, voltage, protection and other information of the equipment can be collected and transmitted back to a remote background through a communication channel and can be called and displayed by a computer terminal; remote signaling means that a dispatcher can communicate with on-site equipment through operation at a computer terminal to test a channel, check whether the equipment is offline or not and the like; the remote control technology means that a dispatcher can remotely control field equipment through a computer terminal.
Furthermore, the fault rapid processing module also comprises an alarm module, the alarm module is composed of an alarm lamp and a buzzer, and the alarm module carries out popup window display according to preset fault grade classification.
Furthermore, the intelligent billing module is composed of an application form management module and an instruction form management module, wherein the application form comprises an outage application form, a mode application form, an external unit application form, an expansion application form, a fault first-aid repair form and a client outage and reinstatement form.

Example 2
Referring to fig. 1-2, a workflow of an online monitoring system based on transmission line automation is provided for another embodiment of the present invention.
The working principle of the fault rapid processing module is as follows:
1) The 35kv feeder outlet switch trips. The CC2000 system can pop a window to prompt fault information, which comprises the following steps: after the fault rapid processing module receives a jump signal transmitted by a CC2000 system, a trip and shutdown dual number is taken out, then a DMS1000E module is found, a transaction window of a contact diagram where the switch is located is taken out according to a time node of a CC2000 message, all transaction messages within 2 hours before message time in the transaction window are taken out, equipment IDs in the transaction messages and equipment IDs between the trip switch and breakpoints are compared in sequence, whether the messages belong to equipment from the trip switch to the breakpoints is judged, if yes, the messages are taken out and displayed in a list, and therefore the transaction messages of all equipment powered by the power supply within 2 hours appear in the list according to the time sequence, the closer to the trip time of the switch, the higher the list is, and after the list is screened, the content in the list is processed on the next step. The system can automatically match the switch trip protection information transmitted by the CC2000 with the protection information of the items in the list according to the sequence of the list, screen item bars from high to low according to the information similarity, for example, 35kv feeder outgoing line switch trip protection information is B-phase overcurrent protection, screen item bars containing B-phase overcurrent protection actions, combine the equipment IDs of the item bars according to the topological relation of a contact diagram, analyze the most probable fault point, generate a strategy window pop-up prompt, screen the specific content and the appearing time sequence of the screened item bars, and when the item bars have no protection signals with high similarity, screen the next keyword according to the pre-input matching priority sequence, such as B-phase voltage loss, and finish the extraction work of the item bars according to the sequence. The priority order of the keywords mentioned here is that a special storage module is arranged in a database, each protection name of a 35kv feeder switch is followed by a list, the protection action names of the distribution network equipment corresponding to the protection name are stored in sequence from high matching degree to low matching degree, and when the protection action occurs, the list is called to screen the item.
2) And the three-phase voltage of the bus of the transformer substation is unbalanced. Bus voltage imbalances can in turn be divided into two types: complete loss of land and incomplete loss of land. a. Completely losing: one phase of three-phase voltage of the bus is close to 0, the other two phases of three-phase voltage are increased to be close to 10kv, and the condition of complete ground loss is that one phase of cable in a cable network has a cable fault or one phase of high-voltage line of an overhead line is broken; b. in the incomplete field of loss: one of three-phase voltage of the bus is reduced, usually 2kv-5kv, and the other two are increased but not close to 10kv, usually 7kv or 8kv, so that most of the faults of incomplete grounding occur in an overhead line, and the reason may be that branches press on a high-voltage bare conductor, or a certain porcelain insulator is broken, an insulating device is not completely damaged, and the like. The fault fast processing system judges whether the fault belongs to a complete fault or an incomplete fault in advance according to the fault information sent by the CC2000, then arranges a plurality of feeder lines from large to small according to the possibility according to the rule input in advance (the line selection rule of a program is input in advance by a dispatcher according to experience) in combination with the feedback of a fault line selection device, the zero sequence currents of all feeder lines of a fault bus and the like, considers that the fault is caused by the fault of the feeder line, then finds a matter window of the feeder lines by a DMS1000E module, finds out possible fault feeder lines and fault points by integrating all information according to the method described above, and provides a strategy for isolating the fault and recovering the normal power supply of other equipment.
3) And (4) losing voltage of a half station or a whole station of the transformer substation. The fault is usually caused by a main network fault, a distribution network dispatcher needs to make a call to a previous-level dispatch to inquire whether the fault is definitely caused by the main network fault, if the answer is uncertain, the distribution network dispatcher needs to check whether all feeders on a voltage-loss bus have obvious switch protection starting or not, but the switch refusing condition is detected, if the signal is generated, the fault on the feeder is possible, the 35kv feeder has the switch protection refusing to cause the fault to override, and the higher-voltage-level switch is tripped, if the condition is suspected, the refusing switch needs to be opened through a CC2000 system, then the condition that other line switches are transferred and reported after no protection action is detected is wanted, and the local dispatching determines whether to transfer power transmission from the main transformer side or transfer the distribution network load completely according to the operation condition of main network equipment. If no switch protection signal exists on the no-voltage bus, all feeder line outgoing switches connected with the bus are firstly switched to be hot for standby through a three-remote system, then a local dispatching and dispatching person reports the situation, 35kv feeder lines are sent one by one after waiting for load transfer or after the main transformer transmits power, if the load needs to be transferred, the scheme of mode adjustment is realized, and whether the opposite side feeder line and the main transformer are overloaded or not is firstly calculated. Such faults are large in power outage area and influence range and involve the cooperation of two-stage dispatchers, usually, a fault rapid processing module is not used for generating a strategy, but a DMS1000E can be used for monitoring mode adjustment schemes, statistics influences double (multiple) power supplies, important users and the like, influences auxiliary functions such as loads and the like.
The fault rapid processing module further comprises an alarm module, the alarm module is composed of an alarm lamp and a buzzer, and the alarm module carries out popup window display according to preset fault grade classification.
The intelligent invoicing module is composed of an application form management module and an instruction form management module, wherein the application form comprises an outage application form, a mode application form, an external unit application form, an expansion application form, a failure first-aid repair form and a client outage and restoration, after any type of application form is selected, the application form can be added from the system according to application form time or fuzzy matching of keywords of the work content of the application form and the like through newly adding in a window of a popup window, after the addition of the application form is completed, the correctness and completeness of the work content, safety measures and the like of the application form are checked through 'application form detection', and after the system returns a result of 'checking correctness', a power failure instruction form 'can be automatically generated by the system through a' newly added power failure instruction form 'tool, and then the generation of a power restoration instruction form is completed through a' power failure to restoration 'tool'. The "instruction ticket management" manages according to an operation sequence of an instruction ticket, and includes: creating an instruction ticket, editing the instruction ticket, auditing the instruction ticket, executing the instruction ticket, pre-ordering the instruction ticket and inquiring the instruction ticket.
The intelligent billing module also comprises reading of the application form, auditing of related data and drawing up of the instruction ticket.
The work flow of the intelligent billing module is as follows:
firstly, an inactive application form is imported, and the system automatically extracts, analyzes and verifies whether the work content, the safety measures and the mode arrangement on the application form are correct or not. The system can obtain the required planned power-off and power-on time, work content, safety measures, operation mode arrangement and the like on the outage application form with a fixed format, and carries out simple logic judgment, such as: the scheduled power transmission time is later than the scheduled power failure time; the working content and the equipment names of the safety measures are matched with a GIS graphic system, the positions of the equipment are found, the working range and all power points (including a transformer substation outlet switch, a self-contained power user, a double (multiple) power user, a transformer with a self-contained power supply and the like) in the working range are analyzed, then whether the safety measures listed on the application form disconnect the power points in the working range or not is judged, and whether the running mode on the application form is reasonable or not, whether the running mode is correct or not is judged according to the current running mode of the GIS and the like.
After the required information is analyzed, the manual drawing-up of the power failure instruction ticket is simulated, the system calls rules input in advance, and the power failure instruction ticket is drawn up one by calling common terms of the database according to the power failure logic. 1) Extracting operation units to which all equipment needing to be operated belongs, and prompting the preparation operation and the power failure starting time on the application form in a line; 2) If the operation mode has the ring closing and opening operation, the ring closing and opening operation is performed according to the sequence of ring closing first and ring opening later, and after the ring closing and opening operation is completed, the short-time power-off operation arranged by the operation mode is operated; 3) And after the mode operation is finished, starting to operate safety measures according to the principle that all power supply points are stopped first and then other safety measures are operated. After each instruction, a check program is called to check whether the rule is met, and the check program contains all the rules, such as: the disconnecting switch can not be loaded when being disconnected (the disconnecting switch is only allowed to be disconnected when no power supply exists, or the disconnecting switch without the load is pulled when the power supply exists); when a line is maintained, if the line is on a main line, all opposite side equipment is required to be in a cold standby state (disconnecting switches are in a disconnected state), if the line is on branches, power supply points of the branches are required to be disconnected, and the like; 4) When the power-on command ticket is drawn, whether the application form has an abnormal operation sheet or not is judged, if the abnormal operation sheet exists, a graphic system after the abnormal operation (the abnormal operation sheet is associated with the application form, and a wiring diagram after the abnormal operation is drawn on the abnormal operation sheet) is read, and the graphic system after the abnormal operation is taken as a model to draw the power-on command ticket. The principle of drawing a power-restoration instruction ticket is the same as that of a power-failure instruction ticket, but the power-restoration logic is opposite to the power-failure logic, and the details are not described here.
