Description

Technical Field

[0001] The present invention relates to the technical field of power supply quality supervision, and more specifically, to an intelligent supervision system for power supply quality of a distribution network. Background Art

[0002] The intelligent supervision system for power supply quality of distribution network is an intelligent system that uses advanced information technology, sensor technology, data analysis and processing technology, etc. to monitor, analyze, evaluate and control the power supply quality of distribution network in real time. Its purpose is to ensure that the distribution network can provide users with stable, efficient and high-quality electricity, meet the requirements of various types of electrical equipment for power quality, and improve the operation management level and economic benefits of the distribution network.

[0003] The most critical part of the intelligent supervision system of power supply quality in distribution network is the source of data, among which real-time monitoring is the source of data. By installing various sensors and monitoring equipment at the key nodes of the distribution network, the data source is provided for the entire intelligent supervision system of power supply quality in distribution network. However, the key nodes of the distribution network usually only have one set of monitoring equipment. If the monitoring equipment fails, it cannot provide data support, resulting in the failure of the intelligent supervision system of power supply quality in distribution network to work properly. In addition, all monitored data will be transmitted to the data processing and analysis center in the intelligent supervision system of power supply quality in distribution network. The data processing and analysis center needs to process and analyze all the data, which will cause the data processing and analysis center to operate at high load, affecting the stability of the data processing and analysis center. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an intelligent monitoring system for power supply quality of a distribution network to solve the background technical problems.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] The intelligent supervision system for power supply quality of the distribution network includes a data acquisition system, wherein the output end signal of the data acquisition system is connected to a preprocessing system, the output end signal of the preprocessing system is connected to a data transmission module, and the output end signal of the data transmission module is connected to a data processing and analysis center;

[0007] The data acquisition system includes a monitoring device 1 and a monitoring device 2, and the output ends of the monitoring device 1 and the monitoring device 2 are both connected to the preprocessing system signal.

[0008] As a further description of the above technical solution:

[0009] The preprocessing system includes a processing module, a control module and a comparison module. The input end of the processing module is respectively connected to the signals of monitoring device one and monitoring device two, the output end of the control module is respectively connected to the signals of monitoring device one and monitoring device two, and the comparison module is bidirectionally connected to the processing module.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0020] See also Figures 1 to 3In the present invention: the intelligent supervision system for power supply quality of distribution network includes a data acquisition system 1, the output end signal of the data acquisition system 1 is connected to the preprocessing system 2, the output end signal of the preprocessing system 2 is connected to the data transmission module 3, and the output end signal of the data transmission module 3 is connected to the data processing and analysis center 4; the data acquisition system 1 includes a monitoring device 101 and a monitoring device 2 102, and the output ends of the monitoring device 1 101 and the monitoring device 2 102 are both connected to the preprocessing system 2 signal; the preprocessing system 2 includes a processing module 201, a control module 202 and a comparison module 203, the input end of the processing module 201 is respectively connected to the monitoring device 1 101 and the monitoring device 2 102 signal, the output end of the control module 202 is respectively connected to the monitoring device 1 101 and the monitoring device 2 102 signal, and the comparison module 203 is bidirectionally connected to the processing module 201.

[0021] In the present invention, a data acquisition system 1, a preprocessing system 2 and a data transmission module 3 are arranged at each key node of the distribution network. The data acquisition system 1 uses a monitoring device 101 and a monitoring device 2 102 to monitor the data of the distribution network nodes. The monitored data will first be input into the processing module 201 in the preprocessing system 2. The processing module 201 will analyze the data of the node. If the monitored data meets the normal value, the data transmission module 3 will upload the data to the data processing and analysis center 4. The data processing and analysis center 4 will process and analyze the data and analyze the power supply quality of each distribution network node. If there is an abnormal power supply, the data processing and analysis center 4 will issue an alarm and the staff terminal will be reminded, thereby realizing intelligent supervision of the power supply quality of the distribution network.

[0022] During actual use, monitoring device 1 101 and monitoring device 2 102 can collect data from the same node at the same time, forming a redundant design. When one set of equipment fails or the data is abnormal, the other set of equipment can still provide accurate data, ensuring the continuity and reliability of data collection.

[0023] By comparing the data collected by monitoring device 1 101 and monitoring device 2 102 through comparison module 203, abnormal data or equipment failure can be identified. If the data of the two sets of equipment are significantly different, the operation and maintenance personnel are prompted to perform inspection and maintenance.

[0024] The control module 202 can independently control the start-up of the monitoring device 1 101 or the monitoring device 2 102 to facilitate comparison of the detected data.

[0025] If the processing module 201 analyzes the same abnormal situation in the data monitored by monitoring device 1 101 and monitoring device 2 102, the node data will be marked, and the marked erroneous data will be sent to the data processing and analysis center 4. The data of the node can be analyzed in detail first, thereby reducing the workload of the data processing and analysis center 4 and improving the stability of the distribution network power supply quality intelligent supervision system.

[0026] See also Figure 1 , wherein: the output end signal of the control module 202 is connected to the alarm module 5 , and the output end of the alarm module 5 is connected to the data processing and analysis center 4 by signal.

[0027] In the present invention, when monitoring device 1 101 or monitoring device 2 102 obtains two different sets of data, it means that there is a quality problem. The alarm module 5 will issue an alarm, and the data processing and analysis center 4 will pass the signal to the staff after receiving it, and then maintain the monitoring device 1 101 or monitoring device 2 102 of the problematic node to improve the practicality of the device.

[0028] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
