Description

Technical Field

[0001] This topic generally relates to an overhead power distribution system, and more particularly to a method, surge catcher, and system for optimizing lightning protection of overhead power distribution lines and equipment. Background Technology

[0002] Frequent lightning strikes typically damage overhead power distribution systems and cause power outages. Lightning is relatively frequent in areas such as southwestern Saudi Arabia, and is therefore a major cause of damage and outages in overhead power distribution systems. For example, the Abahar region of Saudi Arabia, located at high altitude, experiences a maximum ground lightning density (GFD) of 12 lightning strikes per kilometer per year, significantly higher than other parts of Saudi Arabia. This high level of lightning increases the likelihood of power outages in overhead power distribution systems. Furthermore, analysis of outage data has shown that lightning is a primary cause of power outages and a leading factor in customer outage minutes (CML).

[0003] The types of damage that lightning can cause include:

[0004] Permanent damage: Lightning can cause permanent damage to the insulation of lines and / or equipment. This is usually uncommon, but lightning can damage insulators or cause equipment such as transformers to fail.

[0005] Surge catcher failure: High-amplitude lightning flashes can cause surge catchers to fail. Typically, these catchers have a disconnection mechanism that should operate to allow for successful reclosure, but sometimes these catchers fail to clear the connection, leaving a permanent fault that requires interruption.

[0006] Fuse Operation: If a fault caused by lightning blows a fuse, this results in a continuous interruption without any equipment damage. In this case, personnel will have to replace the blown fuse.

[0007] Reclosing malfunction: If reclosing is too fast or malfunctioning, the catcher circuit will experience a continuous interruption. Some lightning events involve multiple strokes lasting more than one second, leading to reclosing malfunctions.

[0008] Conductor slapping: A fault caused by lightning can cause conductors to begin slapping. Conductors on the upstream span may slap together and cause a second (or third) fault. This can lead to circuit lockout. This is most common in (1) spans with high conductor sag, (2) high fault current, (3) close conductor spacing, and (4) small conductors.

[0009] Burnout or other fault damage: Faults caused by lightning may burn out overhead conductors. This is most common in (1) high fault currents, (2) long fault durations, (3) small conductors, and (4) any situation that prevents the arc from moving. Fault currents may also damage and separate in-line joints.

[0010] Many of the aforementioned problems can be avoided by increasing the insulation level of the overhead system, applying appropriately sized lightning arresters, or reducing grounding resistance. However, all of these methods are difficult to apply to existing overhead power distribution systems. Therefore, an analysis to reduce lightning-induced power outages becomes necessary.

[0011] The information disclosed in the background section of this disclosure is intended to enhance understanding of the general background of the invention and should not be construed as confirmation of prior art known to those skilled in the art or as any form of implication.

[0048] Memory 105 is communicatively coupled to processor 107 of lightning protection optimizer system 101.

Finally, the lightning protection optimizer system 101 can use the one or more output parameters, one or more surge arresters, critical flashover voltage, and at least one of shielding wire to determine at least one optimized lightning protection configuration for the existing overhead power distribution line structure. Optimized lightning protection configurations include different types of systems for optimizing lightning protection of overhead power lines and equipment (see reference). Figures 5a to 7f (To be explained), the different types of systems include surge catchers.

[0052] Figure 2 A detailed block diagram of a lightning protection optimizer system according to some embodiments of the present disclosure is shown.

[0053] In addition to the aforementioned I / O interface 103 and processor 107, the lightning protection optimizer system 101 also includes data 201 and one or more modules 211, which are described in detail below. In this embodiment, data 201 is stored in memory 105. Data 201 includes, for example, input data 203, output data 205, and other data 207.

[0056] Other data 207 may store data generated by one or more modules 211 used to perform various functions of the lightning protection optimizer system 101, including temporary data and temporary files.

[0057] In this embodiment, data 201 in memory 105 is processed by one or more modules 211 present within memory 105 of the lightning protection optimizer system 101. In this embodiment, the one or more modules 211 may be implemented as dedicated hardware units. As used herein, the term module refers to an application-specific integrated circuit (ASIC), electronic circuitry, a field-programmable gate array (FPGA), a programmable system-on-a-chip (PSoC), combinational logic circuitry, and / or other suitable components that provide the described functionality. In some implementations, one or more modules 211 are communicatively coupled to processor 107 to perform one or more functions of the lightning protection optimizer system 101.

[0062] like Figure 3 As shown, method 300 includes one or more blocks for optimizing lightning protection of overhead power lines and equipment. Method 300 can be described in the general context of computer-executable instructions. Typically, computer-executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions that perform a specific function or implement a specific abstract data type.

[0063] The order in which method 300 is described is not intended to be construed as limiting, and any number of blocks described in the method block can be combined in any order to implement the method. Furthermore, individual blocks can be removed from the method without departing from the scope of the subject matter described herein. Moreover, the method can be implemented in any suitable hardware, software, firmware, or a combination thereof.

[0067] Figure 4a Illustrations of surge catchers according to some embodiments of the present disclosure are shown.

[0068] exist Figure 4a The surge arrester includes a lightning arrester 409 and multiple magnetic discharge rings 407-1 and 407-2. The lightning arrester 409 can be, but is not limited to, a rod-gap lightning arrester, a valve-type lightning arrester, or a metal oxide lightning arrester. The first end of the lightning arrester 409 is connected to a pole (not shown) via an anchor shackle 405. Figure 4a The crossarm 403 (in the middle). The second end of the lightning arrester 409 is connected to the phase conductors of multiple phase conductors via a machine bolt 411 and a parallel slot compression member 415 through a cable 413, such as Figure 4aAs shown. A first magnetic discharge ring 407-1 of a plurality of magnetic discharge rings 407-1, 407-2 is connected to a first end of a lightning arrester 409. A second magnetic discharge ring 407-2 of a plurality of magnetic discharge rings 407-1, 407-2 is connected to a second end of the lightning arrester 409. Each of the first magnetic discharge ring 407-1 and the second magnetic discharge ring 407-2 is connected to a tap lead oriented toward each other; that is, the first magnetic discharge ring 407-1 is connected to tap lead 417-1 and the second magnetic discharge ring 407-2 is connected to tap lead 417-2. The orientation between the first magnetic discharge ring 407-1 and the second magnetic discharge ring 407-2 can be changed to obtain the desired spark gap value between the tap leads 417-1, 417-2. Figure 4b A test circuit for testing surge catcher recovery after an impact is illustrated according to some embodiments of the present disclosure. The test circuit shows a surge catcher connected to a multiphase distribution line. In one embodiment, the multiphase distribution line can be, but is not limited to, any one of a two-phase distribution line or a three-phase distribution line. Figure 4c A graph showing the surge catcher's recovery after a 53.4 kA surge (simulating lightning) is presented. This surge / shot exceeded the surge catcher's extinction limit in both peak current (at 267%) and coulombs (at 123%). The surge catcher disclosed herein demonstrated a 500 μs extinction current from the captured charge from the generator on this test circuit without a power follower current, as... Figure 4c As shown.

[0069] Figure 5a A schematic diagram showing the position of the first phase conductor according to some embodiments of the present disclosure is provided.

[0070] refer to Figure 5a The first phase conductor position 501 indicates that the phase conductor is along the crossarm of the pole (not in...). Figure 5a (As shown in the diagram) a vertically sequential arrangement, i.e., each of the multiple phase conductors is separated from its adjacent phase conductor along a direction perpendicular to the crossarm of the pole. The multiphase distribution line is installed on a pole comprising multiple phase conductors. In one embodiment, the lightning protection optimizer system 101 receives multiple overhead distribution system parameters related to the existing overhead distribution line structure from one or more sources 111-1 to 111-n. In this case, the existing overhead distribution line structure represents, for example,... Figure 5aThe first phase conductor position 501 is shown, and multiple overhead distribution system parameters are associated with the first phase conductor position 501. The lightning protection optimizer system 101 determines one or more output parameters based on these multiple overhead distribution system parameters. For example, these parameters could be a span length of 80m, a line length of 100km, a critical flashover voltage of 200kV, a catcher discharge voltage of 10kA of 110kV, a grounding resistance of 20Ω, and a ground lightning density of 12 lightning strikes per kilometer per year. Using these parameters, the lightning protection optimizer system 101 determines / estimates the system flashover frequency to be 145.28, indicating that 99.8% of the total lightning strikes will result in a flashover, such as... Figure 5b As shown. It is also known that grounding resistance in the mountainous region of Abaha can be highly variable due to increased grounding resistance from rocky terrain and the prevalence of ground wire theft. In most cases, grounding resistance has been found to be much higher than the grounding resistance considered in the estimates used here. However, improved grounding resistance may not mitigate the reduction in system flashover frequency, as most of these lightning strikes will occur from the center phase conductor to the outer phase conductor. For the same reason, increasing the critical flashover voltage may also not improve the performance in reducing system flashover frequency, as indicated by… Figure 5c As determined by the lightning protection optimizer system 101 in the middle.

[0071] A common method for protecting overhead power lines and equipment from lightning strikes is to use statically shielded wire. In some embodiments, in Figure 5d The diagram presents a configuration / scheme with a first phase conductor position 501 and a shield wire 503. This shield wire / grounding wire 503 is installed above the phase conductor and is most vulnerable to lightning strikes due to its height. By positioning the shield wire one meter above the center phase conductor, the lightning protection optimizer system 101 estimates / determines a reduction in flashover frequency to 50.95 flashovers per year, or 34.9% of lightning strikes causing flashovers. Figure 5e As shown. However, the effectiveness of the shielding depends on good grounding at each pole. The lightning protection optimizer system 101 estimates / determines that doubling the required 20Ω grounding resistance to 40Ω more than doubles the probability of flashover, exceeding 50%, as... Figure 5e As shown. Depending on the grounding resistance, the effectiveness of lightning performance can also be improved by increasing the critical flashover voltage from 200kV to 300kV, as illustrated by... Figure 5f The lightning protection optimizer system 101 in the system estimates / determines as described.

[0072] In some embodiments, another configuration / scheme for improving lightning protection of overhead power lines and equipment includes, for example, […]. Figure 4aThe surge catcher of this disclosure is applied to the outer phase conductors because these phase conductors are most likely to be struck by lightning compared to the center phase conductors. The lightning protection optimizer system 101 estimates / determines that, for a grounding resistance of 20Ω, the percentage of flashover decreases from 99.8% to 8.6%, as... Figure 5g As shown. However, many structures have much higher grounding resistances, indicating that the actual flashover percentage will be greater than 20%. Furthermore, the lightning protection optimizer system 101 estimates / determines that increasing the insulation between the phase conductor and the grounding crossarm will reduce the flashover percentage, such as... Figure 5h As shown. For example, given a grounding resistance of 20Ω, using an insulator with a critical flashover voltage of 300kV reduces the percentage of flashover to approximately 3.0%.

[0073] In some embodiments, another configuration / scheme for improving lightning protection of overhead power distribution lines and equipment is to apply surge catchers to all phase conductors. Specifically, a system for optimizing lightning protection of overhead power distribution lines and equipment includes multiple surge catchers, each of which is connected to each individual phase conductor of a multi-phase power distribution line on a pole. Each of the multiple surge catchers corresponds to, for example... Figure 4a The surge catcher of this disclosure is shown. In use as... Figure 4a When the surge catcher of this disclosure is equipped with all three phase conductors, the lightning protection optimizer system 101 estimates / determines the percentage of flashovers to 0.6%, as shown. Figure 5i As shown, and by using insulators with a critical flashover voltage of 200kV or higher, the percentage of flashovers is reduced to almost 0%, such as... Figure 5j As shown.

[0074] Figure 6a A schematic diagram showing the location of the second phase conductor according to some embodiments of the present disclosure is provided.

[0075] refer to Figure 6a The second phase conductor position 601 indicates that the center phase conductor is raised above the outer phase conductors to provide some shielding; that is, one of the multiple phase conductors is positioned at the first plane, and the remaining phase conductors of the multiple phase conductors are oriented on the crossarm of the pole (not in the first plane) on a second plane parallel to the first plane. Figure 6a (As shown in the diagram), and the first plane is oriented away from the crossarm and the second plane is oriented towards the crossarm. A multiphase distribution line mounted on a pole includes multiple phase conductors. In one embodiment, a lightning protection optimizer system 101 receives multiple overhead distribution system parameters related to an existing overhead distribution line structure from one or more sources 111-1 to 111-n. In this case, the existing overhead distribution line structure represents, for example,... Figure 6aThe second phase conductor is located at position 601, and multiple overhead distribution system parameters are associated with this location. The lightning protection optimizer system 101 determines one or more output parameters based on these overhead distribution system parameters. For example, these parameters could be a span length of 80m, a line length of 100km, a critical flashover voltage of 200kV, a catcher discharge voltage of 10kA of 110kV, a grounding resistance of 20Ω, and a ground lightning density of 12 lightning strikes per kilometer per year. The center phase conductor can be located one meter above, but is not limited to, the other phase conductors, and is associated with, for example... Figure 4a The surge catcher connection of this disclosure is shown. Given these parameters, the lightning protection optimizer system 101 determines / estimates a flashover percentage reduced to 23%, as... Figure 6b As shown. Depending on the grounding resistance, the effectiveness of lightning performance can also be improved by increasing the critical flashover voltage from 200kV to 400kV, as indicated by... Figure 6c The lightning protection optimizer system 101 in the system estimates / determines as described.

[0076] Figure 7a A schematic diagram showing the location of the third phase conductor according to some embodiments of the present disclosure is provided.

[0077] refer to Figure 7a The third phase conductor position 701 indicates that the phase conductor is along the pole (not in Figure 7a (As shown in the diagram) they are arranged vertically in sequence in a vertical direction, that is, each of the plurality of phase conductors is separated from the adjacent phase conductor along a direction perpendicular to the pole. A multiphase distribution line mounted on a pole includes a plurality of phase conductors. In one embodiment, a lightning protection optimizer system 101 receives multiple overhead distribution system parameters associated with an existing overhead distribution line structure from one or more sources 111-1 to 111-n. In this case, the existing overhead distribution line structure represents, for example,... Figure 7a The third phase conductor location 701 is shown, and multiple overhead distribution system parameters are associated with this location. The lightning protection optimizer system 101 can determine one or more output parameters based on these overhead distribution system parameters. For example, these parameters could be a span length of 80m, a line length of 100km, a critical flashover voltage of 200kV, a catcher discharge voltage of 110kV and a grounding resistance of 20Ω, and a ground lightning density of 12 lightning strikes per kilometer per year. Each phase conductor can be located, but is not limited to, one meter above an adjacent phase conductor. Given these parameters, the lightning protection optimizer system 101 determines / estimates that 99.8% of lightning strikes will result in flashovers, and all lightning strikes will hit the highest conductor (not shown). This scenario is unaffected by improvements in grounding resistance or critical flashover voltage, as the flashover will occur between the highest phase conductor and the center phase conductor.

[0078] A common method for protecting overhead power lines and equipment from lightning strikes is to use statically shielded wires. In some embodiments, Figure 7b The diagram presents a configuration / scheme with a third phase conductor position 701 and a shielding wire 703. This shielding / grounding wire 703 is mounted above the phase conductor and is most vulnerable to lightning strikes due to its height. By positioning the shielding wire at least one meter above the center phase conductor (e.g., 1.2m), the lightning protection optimizer system 101 estimates / determines a reduction in the number of flashovers per year to approximately 69, or 46.3% of lightning strikes causing flashovers, as... Figure 7c As shown. However, the effectiveness of the shielding depends on good grounding at each pole. The effectiveness of lightning protection can also be improved, depending on the grounding resistance, by increasing the critical flashover voltage from 200kV to 400kV, as by... Figure 7d The lightning protection optimizer system 101 in the system estimates / determines as described.

[0079] In some embodiments, another configuration / scheme for improving lightning protection of overhead power lines and equipment is to apply a surge catcher to the topmost / highest phase conductor, i.e., to connect the surge catcher to one phase conductor of a multi-phase power line, wherein the phase conductor is near the top of the pole (not shown). Figure 4a As shown, when the surge catcher of this disclosure is equipped with the uppermost phase conductor, the lightning protection optimizer system 101 estimates / determines that the number of flashovers per year is reduced to approximately 44, or 30.1% of lightning strikes causing flashovers. Figure 7e As shown, and by using insulators with a critical flashover voltage of 200kV or higher, the percentage of flashovers was reduced, such as... Figure 7f As shown.
