Embodiment 1

[0039] like figure 1 As shown, a multifunctional intelligent control system based on a smart meter includes a data collector connected to the station area to collect data from various parts of the station area; a monitoring module connected to the data collector to detect user voltage, current and Electricity, distribution transformer voltage, current, load rate monitoring, reactive power compensation, commutation switch controllable resource information monitoring, household transformer relationship check; data calculation and analysis module, connected with the monitoring module, based on the detection data of the detection module, carry out Analyze the characteristics of the station area; optimize the coordination control module, connect with the data calculation and analysis module, formulate adjustment strategies and adjust the operation status of the station area according to the analysis results of the data calculation and analysis module; the user interaction function m...

Embodiment 2

[0047] This embodiment provides a multifunctional intelligent control system based on a smart meter, and the system execution includes the following steps:

[0048] Step 1. The data collector collects voltage, current, Power, gear information, adjustable capacity and other data information, and send the data to the monitoring module. Automatically collect once every 15 minutes, a total of 96 points of operating data. For special data, the monitoring module collects the voltage and current waveforms of the equipment through instructions according to the needs (electricity stealing behavior, household change relationship check).

[0049] Step 2. Using the data preprocessing technology, the monitoring module first performs data processing, fits the data curve, monitors the user's voltage, current and power, monitors the voltage, current, load rate and gear information of the distribution transformer, and The output of reactive power compensation device and distributed power sup...

Embodiment 3

[0055] In this embodiment, some station areas are selected as samples, a smart meter control system is added to the station area, the power supply parameter changes of the station area before and after access are compared, and the line loss rate is corrected accordingly.

[0056] Table 1 Comparison of three-phase unbalance before and after optimization

[0057]

[0058]

[0059] From the table above and figure 2 It can be seen from the figure that after the power supply in the station area is optimized, the three-phase unbalance has been reduced, so that the line loss rate can be reduced by 1.44%.

[0060] In addition, this embodiment selects 5 station areas, and compares the line loss rate changes before and after the access to the control system. The table shows the comparison of the line loss rates of each station area.

[0061] Table 2 Comparison chart of line loss in station area

[0062]

[0063] Through the comparison of the experimental data of 5 stations, ...

The invention provides a multifunctional intelligent control system based on an intelligent electric meter. The system comprises: a data collector connected in a transformer area and used for collecting the data of all parts in the transformer area; a monitoring module connected with the data collector and used for detecting user voltage, current and electric quantity, monitoring distribution transformer voltage, current and load rate, monitoring reactive compensation and phase-change switch controllable resource information and checking user transformer relation; a data calculation and analysis module connected with the monitoring module and used for carrying out transformer area characteristic analysis according to the detection data of the detection module; an optimization coordinationcontrol module connected with the data calculation and analysis module and used for making an adjustment strategy according to the analysis result of the data calculation and analysis module and adjusting the operation state of the transformer area; and a user interaction function module connected with the data calculation and analysis module and used for feeding back the transformer area state information to a user and providing an interaction interface. According to the invention, the problem of difficulty in transformer area monitoring and management is solved, and the fine management levelof the transformer area is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a multifunctional intelligent control system based on an intelligent electric meter. Background technique [0002] The number of stations is large, the grid structure is complex, there are many users, and there are many and miscellaneous equipment. method. With the full coverage of smart meters in the station area and the refined management and control of the station area under the background of the transparent power grid, the technology has gradually matured. [0003] At present, there are the following deficiencies in the management and control of the station area: [0004] 1) The line loss rate in the station area is high, and abnormal situations occur from time to time. [0005] 2) The low voltage in the station area cannot be effectively monitored and managed, and the power outage cannot be effectively monitored and informed. [0006] 3) During the management pro...
