Description

Technical Field

[0001] The present invention relates to the technical field of power outage tracing, and particularly relates to a system and method for power outage tracing, positioning and marking based on a topological search algorithm. Background Art

[0002] In the power department, being able to quickly master the power outage situation in the relevant area and promptly conduct fault troubleshooting and restore power supply when a power outage occurs in the relevant area is the basis for ensuring normal power consumption in the relevant area. In the prior art, the power supply department can only master the overall power outage situation in a relatively large area. That is to say, when a power outage occurs in the relevant area, it is impossible to accurately understand the specific situation of the power outage point. For example, it is impossible to know which transformer supplies power to the area where the power outage occurs. (For the point area supplied by the relevant transformer, such as the power supply of a certain community stops, usually it is reported by the property management or residents by phone. Especially during late-night hours, when the property management or residents do not report the power outage situation in a timely manner, or when the on-duty personnel of the power supply management department are temporarily not on duty, or when the phone line is busy or there is a communication line failure and other emergencies, the management personnel of the power supply management department cannot timely understand the power outage situation). In this way, it will have an adverse impact on the timely restoration of power supply in the relevant area.

[0003] Moreover, with the current technology, the relevant management personnel of the power supply department cannot specifically understand the specific data of relevant power supply points, core equipment such as transformers, etc. For example, it is impossible to know that the transformer has been repaired many times and what the main faults were in its historical repairs. In this way, even if the relevant personnel can timely understand the specific power outage point, they cannot fully make preparations in advance (such as not being able to prepare the maintenance tools and replacement parts in advance according to the historical prone-to-failure of the relevant transformer). When arriving at the scene, they cannot promptly eliminate the faults of the transformer, etc., which will also have an adverse impact on the timely restoration of power supply in the relevant point area.

[0004] In order to overcome the drawbacks in the existing power management departments that due to the inability to timely understand the power outage situation at relevant points and the maintenance historical data of important equipment (such as transformers) at relevant points, the normal power supply at relevant points cannot be restored in a timely manner, the present invention provides a power outage tracing, positioning and marking method based on a topological search algorithm, which can timely prompt the power supply management department when a power outage occurs in the relevant area under the combined action of relevant institutions and methods, and prompt (including the location data of the power outage point, the maintenance historical data of transformers at relevant points, etc.) relevant maintenance personnel to go to the scene for repair through the internal network and SMS of the power supply management department, thereby bringing convenience to the staff, correspondingly improving the maintenance efficiency, and increasing the speed of power supply restoration.

The other end of the second resistor R6 is connected to the negative pole of the capacitor C2 and the negative power output terminal 4 of the rectifier bridge U3. The two power output terminals 3 and 4 of the current transformer U7 are respectively connected to the two power input terminals 1 and 2 of the rectifier bridge U3. The fault type input circuit has the same multiple paths. Each path of the fault type input circuit includes resistors R9 and R10 and a power switch D1. One end of the power switch D1 is connected to one end of the first resistor R9. The other end of the first resistor R9 is connected to one end of the second resistor R10. The buttons of multiple power switches D1 are respectively located outside multiple openings at the front end of the component box. The side end of the button of each power switch D1 is marked with prompt text representing the fault type of the electrical equipment. The resistance values of the first resistors R9 in multiple paths of the fault type input circuit are inconsistent, and the voltage signals output by multiple paths of the fault type input circuit are inconsistent.

[0042] Figure 1 , 2As shown, the power input terminals 1 and 2 of the power module U1 are electrically connected to the two poles of the AC 220V power supply respectively. The power output terminals 3 and 3 of the power module U1 are electrically connected to the two poles of the battery G1, the power input terminals 1 and 2 of the 5G module U5, the power input terminals 1 and 2 of the single-chip microcomputer module U4, the power input terminal of the relay J1 that controls the power input of the power input terminal of the power outage and phase loss detection circuit and the other end of the resistor R2, the other end of the resistor R4 at the power input terminal of the voltage detection circuit, the other end of the resistor R6 at the power input terminal of the current detection circuit, the other end of the power switch D1 at the power input terminal of the fault type input circuit and the other end of the resistor R10 respectively. The signal input terminals of the power outage and phase loss detection circuit, the power input terminals of the relays J1, J2, J3 and the other power input terminals of the relays J1, J2, J3 are electrically connected to the three phase lines L1, L2, L3 and the neutral line H of the transformer T respectively; the signal input terminals of the voltage detection circuit, the 1st and 2nd pins of the rectifier bridge U2 are electrically connected to one of the phase lines and the neutral line of the transformer T.

The signal output terminal of the single-chip microcomputer module U4 and the signal input terminal of the 5G module U5 are connected by wires.

[0043] Figure 1 , 2As shown in the figure, the 220V power supply enters the power input terminal of the power module U1. The stable DC 12V power supply output from pins 3 and 4 of the power module U1 enters the two poles of the battery G1 and the power input terminals of the 5G module U5, the single-chip microcomputer module U4, the power outage and phase loss detection circuit, the voltage detection circuit, the current detection circuit, and the fault type input circuit. The above modules and circuits are powered on and work (the battery G1 is floating charged usually, so that when there is a power outage in the relevant area, the relevant electrical equipment can continue to be powered on and work). After the leakage detection circuit is powered on and works, when there is no leakage in the electrical equipment at the relevant point (such as the power supply and electrical equipment including transformers in a certain community), the 3rd pin of the leakage detection module U does not output a voltage signal; when there is leakage in the electrical equipment at the relevant point, the 3rd pin of the leakage detection module U outputs a voltage signal, and the voltage signal enters the 4th pin of the single-chip microcomputer module U4 after being divided by the resistors R7 and R8 (the higher the leakage voltage, the higher the voltage signal; vice versa, the lower). After the power outage and phase loss detection circuit is powered on and works, when there is no phase loss at the output terminal of the transformer T (or there is no power outage), the relays J1, J2, and J3 will be powered on and attracted. When the relays J1 and J2 are powered on and attracted, their control power input terminals and normally open contact terminals are closed. When the relay J3 is powered on and attracted, its control power input terminal and normally closed contact terminal are open. In this way, no voltage signal enters the 6th pin of the single-chip microcomputer module U4; when there is a phase loss at the output terminal of the transformer T (or there is a power outage), the relays J1 or J2, and J3 will lose power and no longer be attracted. After the relays J1 and J2 lose power, their control power input terminals and normally open contact terminals are open. After the relay J3 loses power, its control power input terminal and normally closed contact terminal are closed (the loss of power of either the relay J1 or J2 will cause the relay J3 to lose power). In this way, the 12V power supply will enter the 6th pin of the single-chip microcomputer module U4 after being divided by the resistors R1 and R2. After the voltage detection circuit is powered on and works, the power supply output from the transformer T enters the power input terminals 1 and 2 of the rectifier bridge U2. The rectifier bridge U2 will output a DC power supply from pins 3 and 4, which enters the 4th pin of the single-chip microcomputer module U4 after being divided by the resistors R3 and R4 (the capacitor C1 has a filtering effect; the higher the voltage signal output from the transformer T, the higher the voltage signal input to the 4th pin of the single-chip microcomputer module U4; vice versa, the lower). After the current detection circuit is powered on and works, when the electrical load is large, the current and voltage signals output from the secondary side of the current transformer U7 are relatively low. When the electrical load is small, the current and voltage signals output from the secondary side of the current transformer U7 are relatively high. The voltage signal enters the power input terminals 1 and 2 of the rectifier bridge U3. The rectifier bridge U3 will output a DC power supply from pins 3 and 4, which enters the 3rd pin of the single-chip microcomputer module U4 after being divided by the resistors R5 and R6 (the capacitor C2 has a filtering effect; the higher the load output from the transformer T, the higher the voltage signal input to the 3rd pin of the single-chip microcomputer module U4; vice versa, the lower).After the multi-channel fault type input circuit is powered on and working, every time the staff repairs the transformer T or other auxiliary electrical equipment, they press one of the corresponding power switches D1. Then, after the power switch D1 representing the fault type of the transformer T or other auxiliary electrical equipment is closed, the 12V power supply will be divided by the corresponding resistor R9 and R10 and enter one or more of the other signal input terminals of the single-chip microcomputer module U4.

[0044] Figure 1 , 2 As shown in, after the single-chip microcomputer module U4 works, it converts the multi-channel analog voltage signals representing whether there is leakage, power outage, or phase loss at the site (after receiving the power outage or phase loss data remotely, it is uniformly displayed as a power outage or phase loss), voltage and current, and the fault type of electrical equipment into digital signals, and then sends them out wirelessly through the data sending unit of the 5G module U5. After the data receiving unit receives the multi-channel data sent by the data sending unit and performs preliminary processing, it outputs the data to the data classification unit. The data classification unit classifies the various data according to the data on leakage, power outage or phase loss, voltage and current, and the fault type of electrical equipment, and outputs the data to the positioning and marking unit. Then, the positioning and marking unit calculates which specific power supply point has leakage, power outage, or phase loss, as well as the voltage and current data of the electrical equipment and the type data of the electrical equipment failure according to the positioning function of the 5G module itself, and outputs the above data to the display unit and the prompt unit; specifically, in the process of calculating the type data of the electrical equipment failure by the positioning and marking unit, its basic data comes from the different voltage signals transmitted by the multi-channel fault type input circuit, and each voltage signal represents a fault type of an electrical equipment. The positioning and marking unit can accumulate the data such as the number of occurrences and the duration of each type of fault, and at the same time, the above data is displayed by the display unit and the prompt unit pushes a text message. Finally, the display unit displays on the display screen connected to the PC of the power supply management department the specific geographical location data (including voltage and current data) of the power supply point where there is leakage or electrical equipment failure, power outage or phase loss.
