Intelligent distribution network acquisition and monitoring system

Abstract

An intelligent distribution network acquisition and monitoring system includes: an electrical parameter acquisition front end and an electrical parameter data acquisition management system. The electrical parameter acquisition front end is used for acquiring electrical parameter data. The electrical parameter data acquisition management system is used for analyzing and managing the data acquisition, collecting electric energy data, and for data processing, computing, and analysis and decision, automatically acquires electric energy meter data, remote measuring data, remote communication data, and remote regulation data by communication with distribution transformer terminal equipment or directly with the electric energy meter, can acquire different items, can take the initiative in reporting failure or other information, has an automatic recording and charging function according to set cycles and a random selective recording function according to needs, can reliably and securely acquire, transmit, and store information, and meets actual needs to the utmost extent. For the measuring point that cannot be recorded, the system gives alarms in a variety of ways to make workers on duty record manually. The data that cannot be recorded because of the failure of a main station system can be automatically measured when the system restores normal.

Description

technical field [0001] The patent of the present invention relates to an intelligent system for data acquisition and monitoring, especially an intelligent distribution network acquisition and monitoring system. Background technique [0002] With the rapid development of scientific application technology, in the field of electric meter reading, there have been a variety of meter reading schemes coexisting, such as traditional manual meter reading, leased telephone line meter reading, low-voltage power carrier meter reading, optical fiber meter reading, etc. However, these meter reading methods have their own defects. The traditional meter reading method manually reads the energy meter data from door to door, which will inevitably lead to inaccurate statistical data and cannot truly reflect the electricity consumption of users; it is difficult to standardize the operation and cause unknown losses. increase; and consume a lot of manpower, high cost and low efficiency. Obviousl...

Problems solved by technology

However, infrared is used for wireless meter reading, which has its own insurmountable shortcomings: strong directionality, strict angle requirements; short transmission distance, and affected by weather; easy to be interfered by various heat sources and light sources; , and the use of radio frequency technology in the meter reading system, which has been widely concerned at present, can solve the above problems well. Using the Internet of Things IOT radio frequency meter reading system, it can perform wireless meter reading accurately, quickly and in a timely manner no matter it is outdoors or indoors.

The hand-held meter reading device can realize the function of wireless meter reading, and can complete the communication, storage and uploading of meter data, but the economic development and the improvement of people's living quality have put forward higher requirements for the construction of distribution network, and distribution network automation is to improve One of the most important means to manage the level of distribution network and improve the reliability of power supply. China's distribution network is intricate and prone to failure; especially ground faults, due to their recessive characteristics, are difficult to find, and sometimes they have to be detected by pulling the segment switch And test the power transmission to determine the fault area, which is extremely unfavorable to the safety of the line and equipment operation. The traditional fault indicator and switch displacement indicator are used to realize the segmented location of the line fault. The fault information cannot be transmitted remotely, and there is no automatic fault location. Function, which requires manual line inspection, increases the difficulty and time of fault finding; uses highly integrated power distribution terminals to realize functions such as fault identification, fault isolation, network reconstruction, reactive power / voltage control and optimized operation of the distribution network , this solution is of course an important choice for distribution network automation, but the installation and operation are more complicated, and it is difficult to promote in some places
