A6 B6 210408 V. Description of the invention (1) (Please read the precautions on the back before reading this page) The present invention relates to a method and system for cutting off the faulty controller when the power distribution system fails, generally In general, a distribution system includes a distribution station, a distribution line extending from the distribution station, and most of the switch sections can cut the line into a plurality of line segments. In this distribution system, it is necessary to be able to detect the occurrence of a fault. Line segment and cut the fault line away from the normal line quickly. In order to meet this requirement, various methods and methods have been proposed in practice. A typical system consists of a main controller installed at the distribution station, segment controllers installed at individual segment switches, and a transmission system connecting the main controller and each segment controller. If there is a fault, such as a ground fault, which occurs in section η of the distribution line, the fault detection breaker of the substation will open the circuit breaker in the substation. All segment switches are then opened at zero voltage and the circuit breaker is closed again. Therefore, power is supplied from the substation to the first section of the switch (first section). After the circuit breaker is closed again, the first section of the switch calculated from the substation is closed again when the section controller determines that the line on the side of the substation is normal. This same operation is repeated to the n-th stage switch. Printed by Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, but when the section (load section) of the η-segment switch on the distribution side is faulty, if the η-segment switch of the corresponding faulty section is closed, the fault detection of the substation The action of the electrical appliance causes the circuit breaker to trip again. With this disconnection action, the segment controller of the η segment switch determines that the η + 1 segment is the faulty segment. When the circuit breaker is closed again, the segment switch will be closed to the η + 1st segment switch, and the power will be supplied to the segment before the fault segment. Therefore, the power only stops the fault section. This method temporarily interrupts the entire power distribution system, and then sequentially searches for faults in each section, starting from the closest to the power distribution station, so it takes a lot of time to apply the Chinese National Standard (CNS) A4 specifications (210 X 297 Mm) -3-Printed by the Workers ’Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs ** Clothing V.

Description of the invention (13) Time T 2 is short. The operation will be explained below with reference to Figure 10. It is assumed here that the section switches 1 2-1 to 12-4 are in the closed state, in which the power supply is supplied from the substation 10 to the load. In this state, if the fault occurs in segments 1 1 to 3, the fault occurs on the load side, so the segment controllers 30-1 and 30_2 perform fault detection. Other segment controllers 3 0-3 and 3 ◦-4 do not perform fault detection because no fault occurs on the power supply side. The substation 10 also detects a fault on the load side and sends a fault detection signal F D to the main controller 20. After receiving the signal F D, the main controller 20 simultaneously transmits a request i number SV S D to each segment controller 3 0 — 1 to 3 ◦-4. After receiving the signal S V D S, the segment controllers 3 0-1 to 3 0-4 sequentially transmit the fault detection signal S V D 1 1-SVD 14 to the main controller 20 during T s (as shown in the eighth image). Each segment controller 30-1 to 30-4 generates a fault segment decision according to the logic of the ninth circle, and supplies fault detection signals from other segment controllers to control its related segment switches. That is, the segment controller 3 ◦-1 continues to close its segment switch 1 2 — 1, because the segment controller 3 0 — 2 on the load side detects a fault. The segment controller 3 0 — 1 opens its related segment switch 1 2 — 2 and stores the closing prohibition " because the fault is detected by the segment controller 3 0 on the power supply side, not by the segment controller 3 0 — 3 and 3 0 — 4 detected.

Description of the invention (14) Both the segment controller 3 0-1 on the side and the segment controller 3 0-2 on the load side All faults were detected. Note that even if the segment switches 1 2-3 are powered by the load side, they will not be closed because the segment controller 3 0 _ 3 stores " closing prohibition. As described above, the high-quality power system provided by the present invention only cuts off the faulty line segment in the distribution line, and continues to wrap power to the normal line segment on the power supply side of the faulty line segment. In addition, the equipment added to the power distribution system can be reduced. The above-mentioned embodiment illustrates that the segment switch related to the faulty line segment is turned on to cut off the faulty line segment. In the system where the switching capacity of the segment switch is not enough to interrupt the short-circuit current, the following operations shall be performed, that is, after the decision to generate the fault line, the signal will be transmitted by the transmission system. = Although the segment controller that generated the fault segment decision will open its related segment switch, the segment controller on the power supply side of the fault segment does not open its related segment switch, but stores in the case where the fault is short-circuited. . The segment switch will not open until the circuit breaker of the substation has tripped to bring the voltage to zero. When the circuit breaker is closed again, the line controller of the normal section sequentially uses the traditional time-closing function to close its related section switch. The controller on the power supply side of the faulty segment will not close its related segment switch in time, because it has been stored as above and closed a prohibited 〃. In this case, the normal section on the power side of the faulted section will be stopped once due to the trip of the substation circuit breaker to cut off the faulted section. Compared with the two stop of the traditional system, the quality of this system is better. The configuration of the segment controller will be explained in detail in the following figures 1 1, 1 2 and 13. Segment switches 1 2 — 1 to 1 2 — 4 are normally excited and open without voltage.

The auxiliary relay 30T is boosted when the output voltage of the voltage detection section 3 Ο Ν is VD in the presence of a line voltage, and after the ON output of the voltage detection section 3 is turned to zero voltage after the power supply is stopped, there is a fixed time to deenergize .

Description of invention (16) The output of the obstacle detection section 30M is generated, and this section 30M sets the storage circuit 30Q2 ·. After the fault detection, even if the circuit breaker 10A of the substation 10 is tripped, the storage circuit 30Q2 continues to be set to transmit a fault detection signal to the main controller 20. The storage circuit 3 0 Q 2 is reset after T4 set by the delay timer 30Q4. This T4 pseudo storage circuit 3 0 Q2 output and voltage detection circuit 3 0 N output Vd, indicating that the input power is restored to the segment controller , Input and circuit 30C13 is calculated at the beginning. The T4 set by the timer 30Q4 during the delay is set to be longer than the period of time before the circuit breaker 10A detects that the input power is not present in the fault voltage detection section 3 Ο N. Therefore, when a fault occurs, the i signal must be transmitted to the main controller 20, and the storage circuit that stores the fault detection information will automatically reset when the fault (such as an instantaneous ground fault) is restored before the circuit breaker 10A trips . The operation flow of the logic section 20E of the 13th Puyong main controller 20 includes steps 201 to 205. The main controller 20 often polls the segment controller to obtain the fault detection information through the logic segment 20E, the transmission segment 20F and the transmission system 40, and the monitoring segment switch and the fault detection signal. The main controller also monitors the status of the circuit breaker 10A. In this case, if a fault occurs on the distribution line, the fault detection section 30 M will detect the fault through the fault current detection CT 1 2 Β and output a fault detection signal. Logic segment 3 0 Q stores the fault detection information and transmits to the main controller 20 through the transmission segment 3 0 R when the main controller polls. Even if the circuit breaker 10Α is tripped due to a protection relay (not shown) to stop the power supply of the distribution line, the fault detection information will still be transmitted from the segment controller to the main controller, because the fault is recorded by the segment controller.

Description of the invention (17) A fixed time (corresponding to No. 12 圔 T3). The auxiliary relay 30T deenergizes after a fixed time (T 3) to open the contact 30 S. Remove the battery 3 Ο P from the load to prevent over-discharge of the battery. In the main controller 20, the segment controller data received by the transmission segment 3 OR is determined by the logical segment 3 0 Q. In step 201, the logic section 30Q starts to form a fault decision based on the trip information of the circuit breaker 10 A (C B trip). In step 2 ◦ 2. The information is obtained by each section controller after polling by the circuit breaker. In step 2 0 3, the fault segment decision is generated based on the information obtained from the controllers of each segment after the circuit breaker has tripped. For example, when a fault occurs at a point in Fig. 11, each segment controller detects the fault at the detection segment 3 0 M of 0 — 1 and 30 0 2 and causes the logical segment 20 0 E to generate fault detection information. Fault detection information. The fault detection information is transferred from each segment controller to the main controller via the launch segment 2 ◦ F and transmission system 40 when the segment controller power supply is not present. The segment controllers 3 0-3 and 3 0-4 are located on the load side of the fault point, and transmit the same fault-free detection information to the main controller during polling. In step 203, the fault point is determined to be between the segment switches 1 2-2 and 1 2-3 according to the information H of each segment controller, so the fault segment is determined. In step 204, the decision is made by a re-closing relay (not shown), regardless of whether the circuit breaker is re-closed, and then it is ready to be connected. In step 205, in order to restore the power supply of the normal segment before the fault line segment is in the condition that the circuit breaker 10A has been closed again, a command to close the segment switch 1 2-1 is sent to the segment controller 3 0-1 to make the switch 1 2-1 closure. Closing the circuit breaker 10 again allows input power to be added to the segment controller 3 ◦-1.

The segment controller 30-2 also operates to close the segment switch 12-1. There is another system loop on the load side of the fault point, and a close command can be issued from the logic section 20E to the loop point and the section switch 1 2-4. The 12th fault storage logic is not a limitation. To replace the stored VD condition, the autonomous controller can send a reset signal to the fault storage logic. Although the C B trip input information can be used to determine the starting conditions as the segment shown in Figure 13, it can also be replaced by conveyor line fault detection information. In the above, a close command is sent from the main controller to the segment controller to supply power to the normal line segment. Alternatively, each segment control has a built-in fault search function, which can automatically close its respective relevant segment switch after the circuit breaker is closed again. In this case, the main controller, when it detects a fault segment, can issue a command to enable the fault search function of the segment controller that is close to the fault segment. In addition, in the thirteenth, the switch is closed after the circuit breaker is reclosed by the reclosure relay. In addition to re-closing the circuit breaker with a re-closing relay, the main controller can also issue a re-closing command to the circuit breaker after measuring the fault segment. In this case, the re-closing time can be greatly reduced. Non-rechargeable batteries can also be used. The control system of the present invention shown in FIG. 4 will be described below.

Description of the invention (23) Each section controller uses the logic of the 18th circle to determine a fault line section and Switching on and off. If there is no segment controller on the power supply side in this case, it is unconditionally determined that there is a fault detection on the power supply side. If there is no step controller on the load side, no condition is detected and no fault is detected on the load side. The interconnection controller uses the logic in Figure 19 to determine the normal line segment on the load side.

T 1 must be shorter than T 2. The T 2 series substation detects a fault to the circuit breaker 1 ◦ A opens Between a period of time. Next, the operation will be described. Assuming that the segment switches 1 2 _ 1 to 1 2 — 3 are closed, the interconnect switch 1 4-1 to 1 4-3 is open, and the line segment 1 1-1 to 1 1-i is supplied by the substation 10 power supply.

After receiving the SVD15-SVD17 of the segment controllers 3 0 0-1 to 3 0 0-3, the main controller 200 transmits the simultaneous control signal SVC to the transmission system 40. Each controller 30-1 to 30-3 and 50-1 to 50_3 uses the logic of Figure 18 or Figure 29 to control its related switches according to the received fault detection information, in synchronization with the received control signal SVC . In this case, the time t 1 of the controller, that is, the time from receiving the simultaneous control signal to the time when its related switch is closed, must be shorter than the time from receiving the control signal until its related switch is open. This prevents the normal line segment from being blacked out when most switches are exchanged. Next, the operation of each stage control will be described.

As described above, according to the present embodiment, the provided high-quality power supply virtually cuts off only the faulty line segment of the distribution line and prevents power supply from the normal line segment. In addition, equipment added to the power system can be reduced.

The circuit breaker of the substation is then closed again. The segment switch that cuts off the distribution line between the fault and the normal segment and the segment switch that switches on and off will not close even when the power is restored when it is open. This is because the relevant segment controller stores " close prohibition. In this case, there will be a power outage on the normal line segment because the circuit breaker will trip out of the faulty line segment. Compared with the traditional system where power outages occur twice, Datong can reduce the number and time of power outages.

After a fixed time has elapsed, the timer generates an output, 1 〃, and a circuit breaker is given as a trip command via an OR circuit 309. As described above, according to the present invention, the time for tripping the circuit breaker after the operation of relay 1 ◦ B can be delayed by a fixed time, and the time for tripping the section switch can also be delayed. In this way, high-speed operation of the fault detection relay can be avoided and there is sufficient time to measure the faulty line segment. Therefore, even if the instantaneous fault that has been restored before the circuit breaker trips, the segment controller will not open unnecessarily. In addition, delaying the operation time of the substation fault detection relay until the circuit breaker trips can be used to operate between the i controller and the segment controller.

V. Description of the invention (28) The fault detection relay must be operated at high speed. Therefore, a low-cost relay with a simple structure can be used. In addition, because there is enough time to determine the faulty line segment, even if the instantaneous fault that has been restored before the circuit breaker trips, there is no need to make unnecessary trips. The fourth control system can be modified as follows. Although in the above embodiment, a single simultaneous control signal is used, regardless of the type of fault, two types of simultaneous control signals can also be used; a simultaneous control signal for ground fault (SVC 1) and a short-circuit fault Control signal (SVC 2). When the main controller transmits a simultaneous control signal when a ground fault occurs, the time T 5 required to close its related switch after receiving the control signal must be set to a time T 6 that is greater than the controller open time Λ, that is, T 5 > T 6. In this way, the load exchange can be performed first, so that the normal line with the load of the faulty line can continue to be supplied with power. On the other hand, in the case of short-circuit fault simultaneous control signal (SVC2), T5CT6. This prevents short-circuit faults from extending to other power systems. In the above embodiment, only the fault detection function is set in the segment controller. Fault detection can be set in the interconnection controller. In this way, the interconnection controller can be used as a segment controller when the power distribution system changes. The above transmission system (communication line) may have an upper and lower information line.
