Description

Technical Field

[0001] The invention relates to the technical field of power transmission, and in particular to a reactor online monitoring and real-time processing system. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with current is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make the solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactance and capacitive reactance are collectively called reactors. However, since inductors came first in the past and were called reactors, the capacitors people refer to now are capacitive reactances, and reactors specifically refer to inductors.

[0003] However, when a reactor fails in a power grid with a large number of reactors, the reactor is not repaired in a timely manner, and most of the time, manual inspection and maintenance are used. This method can no longer meet the operating needs of the power grid, which in turn leads to the paralysis of the power grid's circuit transmission, increases the risk of power grid accidents, and brings a certain degree of economic losses. Summary of the invention

[0004] Technical issues solved

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a real-time processing system for online monitoring of reactors, which solves the problem that when a power grid with a large number of reactors fails, the reactors are not repaired in a timely manner. Most of the time, manual inspections and maintenance are used, which can no longer meet the operating needs of the power grid, thereby causing circuit transmission paralysis of the power grid, increasing the risk of power grid accidents, and bringing a certain degree of economic losses.

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The present invention will be further described below in conjunction with the embodiments.

[0051] Example 1

[0052] The reactor online monitoring real-time processing system of this embodiment is as follows: Figure 1 As shown, including:

[0053] Control terminal 1 is the main control terminal of the processing system, used to send execution commands for execution by subordinates;

[0054] Analysis module 2, used to analyze the transmission load of the power grid where the reactor is located, the distribution of the power grid where the reactor is located, and detect the properties of the reactor;

[0055] Database 3, used to record power transmission request data and actual power transmission usage within the power grid cycle where the reactor is located;

[0056] Detection module 4, used to detect the aging of each reactor in the power grid, and form recorded data for subsequent step-by-step selective detection;

[0057] Monitoring module 5, used to monitor the discharge of various circuits and components such as reactors in the power grid;

[0058] Evaluation module 6, used for comparing and evaluating the discharge reactor monitored by monitoring module 5 with the corresponding reactor properties in analysis module 2, and feeding back the evaluation result to control terminal 1 by means of non-media transmission;

[0059] Coordination module 7, used to coordinate the shutdown, replacement and maintenance of distributed reactors in the power grid;

[0060] Repair procedure 8, used to repair the reactor;

[0061] The emergency module 9 obtains the sudden fault signal from the monitoring module 5 and is used to handle the sudden fault of the reactor in the power grid;

[0062] A capture module 10 is used to capture the reactor with sudden fault and the fault point of the reactor with sudden fault during the operation of the power grid;

[0063] The holding module 11 is used to temporarily restore the power grid circuit and feed back the fault reactor and the fault point to the control terminal 1;

[0064] The processing module 12 is used to select the low-frequency time domain of the power grid circuit output to replace or repair the fault point of the faulty reactor.

[0065] When this embodiment is used, the control terminal 1 sends an execution command to control the analysis module 2 to run and analyze the transmission load of the power grid where the reactor is located, the distribution of the power grid where the reactor is located, and the detection properties of the reactor. The synchronous control database 3 records the power transmission request data and the actual power transmission usage within the power grid cycle where the reactor is located. The detection module 4 and the monitoring module 5 are used to detect the aging degree and discharge status of the reactor in each power grid. The evaluation module 6 evaluates the situation of the reactor and feeds back to the superior. At this time, the control terminal 1 controls the coordination module 7 to coordinate all the reactors and other components in the power grid;

[0066] For the faulty inductor, the control terminal 1 can repair it through a repair program. When the system responds to a sudden failure of the inductor, the emergency module 9 runs and the capture module 10 is used to capture the fault point of the faulty inductor. During this process, the maintenance module 11 is used to ensure the current stability of the circuit transmission in the power grid. Finally, the faulty inductor is processed by the processing module 12 so that all the inductors, components and circuits in the power grid return to normal.

[0067] Example 2

[0068] like Figure 1 As shown, the reactor property detection comparison items in the analysis module 2 include shunt reactors, series reactors, tuned reactors, incoming line reactors, current limiting reactors, damping reactors, arc suppression coils, smoothing reactors, and DC controlled saturated reactors.

[0069] like Figure 1 As shown, the power transmission request data and actual power transmission usage recording cycle in database 3 is daily, and the recording cycle data is valid for three years. Database 3 clears the data recorded for three years. Database 3 includes a storage module 31 for alternatively storing the distribution of the power grid where the reactor is located and the properties of the built reactor.

[0070] This configuration can effectively improve the timeliness of the response of the database 3 and avoid the situation where the database 3 runs slowly due to excessive backlog of internally stored data caused by long-term use of the database 3.

[0071] like Figure 1 As shown, the monitoring module 5 includes a measuring module 51 for measuring the real-time voltage of each part in the power grid and forming a report file to be transmitted to the control terminal via a medium-free transmission method.

[0072] The measurement module 51 can be used to further monitor the operation of the reactor in the power grid, and the real-time voltage of the reactor can be used as a criterion to predict the probability of failure of the reactor in real time.

[0073] like Figure 1 As shown, the coordination module 7 includes:

[0074] The capacity increasing unit 71 is used to increase the number of operating reactors and is started when the amount of circuit transmission increases suddenly and exceeds the power transmission request during circuit transmission in the power grid;

[0075] A replacement unit 72, used for replacing an aged and faulty reactor;

[0076] The repair unit 73 is used to trigger a repair procedure to repair the reactor that has been electrically broken down.

[0077] The above is the processing method for the faulty reactor in the coordination module 7, which respectively covers the capacity increase unit 71, the replacement unit 72, and the repair unit 73, so as to deal with various possible faults of the reactor.

[0078] like Figure 1 As shown, the processing module 12 establishes a connection with the replacement unit 72 and the repair unit 73 via a wireless network, and the processing module 12 controls the replacement unit 72 and the repair unit 73 to selectively adapt and operate.

[0079] like Figure 1 As shown, the maintaining module 11 establishes a connection with the capacity expansion unit 71 through a wireless network. The operation of the maintaining module 11 triggers the capacity expansion unit 71 to run synchronously to coordinate the reactors in the power grid. The coordination method includes adding reactors in series or parallel or coordinating the existing reactors in the power grid in series or parallel.

[0080] By establishing a connection between the processing module 12 and the replacement unit 72 and the repair unit 73; and maintaining a connection between the module 11 and the capacity expansion unit 71, the response rate of the system when a reactor fails is further improved, the braking effect of the system is effectively improved, and the system handles the faulty reactor more promptly.

[0081] Example 3

[0082] The method for using the repair program in the reactor online monitoring real-time processing system comprises the following steps:

[0083] Step 3: Obtain the distribution location of the reactors in the power grid, capture the faulty reactors in the power grid, establish the coordinates of the faulty reactors, and enter the repair waiting stage;

[0084] Step 2: Use the capacity expansion unit 71 to coordinate and configure the grid circuit, turn off the faulty reactor, maintain the compatibility of the grid circuit, generate a reactor fault information report file to report to the superior, feedback to the power configuration transmission end, and negotiate the power transmission interruption and recovery time;

[0085] Step 3: Wait for negotiation and start repair;

[0086] Step 4: Obtain the fault point of the reactor, and perform appearance inspection and circuit path test on the fault point;

[0087] Step 5: Analyze the fault cause according to the fault point to determine whether the reactor fault point is repairable;

[0088] Step 6: If the result of the judgment in Step 5 is negative, the reactor with better performance than the faulty electrical appliance is selectively replaced;

[0089] Step 7: If the result of Step 5 is yes, repair the circuit and appearance of the fault point of the faulty reactor.

[0090] like Figure 3 As shown, step Step5 includes step Step51: recording the fault cause, analyzing the operating characteristics of the faulty reactor before the fault, and detecting all installed reactors of the power grid according to the operating characteristics of the faulty reactor before the fault.

[0091] This setting enables the above-mentioned repair program to have a certain predictive function, making the actual use performance of the repair program more comprehensive.

[0092] like Figure 3 As shown, the coordinates of the faulty reactor established in step 1 are used to find and repair the faulty reactor after step 3 starts.

[0093] Example 4

[0094] like Figure 2 As shown in the figure, VDD is the inductor voltage; GND is the ground wire; Verf is the overcurrent protection voltage reference terminal; Delay Circuit is the delay circuit; VOUT is the output voltage. Through the circuit diagram of the measurement module 51 integrated with the above components, the real-time voltage of the inductor in the power grid can be detected in real time, thereby providing a reliable evaluation basis for the evaluation module 7.

[0095] In summary, the present invention provides a real-time processing system for online monitoring of the reactor used in the power grid. The system can realize real-time monitoring of the reactor used in the power grid. When the reactor fails, the faulty reactor can be effectively and timely repaired or deployed through the system, thereby ensuring the normal operation of the circuit transmission of the power grid circuit and avoiding the occurrence of large-scale paralysis of the power grid.

[0096] On the other hand, the present invention can accurately locate the faulty inductor in the power grid, so as to facilitate the search when a major fault occurs in the inductor. At the same time, the present invention can perform fault analysis on the faulty inductor, know the fault point and cause of the faulty inductor, and detect all the inductors in the power grid based on this, bringing a certain step-by-step fault prediction effect to the monitoring of the inductors used in the power grid.

[0097] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
