Problems solved by technology

[0004] At present, there are still two problems in the research of power outages in the station area by using intelligent IoT agents. Communication congestion makes it difficult to perceive power outage events; on the other hand, due to the high requirements for communication and equipment energy storage for smart meter power outage reporting after power outages, it is possible for a single or a small number of users to have power outages, refuse to report or fail to detect the possibility of reporting information Larger, causing perception delay and inaccurate statistics of power outage duration
[0005] Therefore, the technology of using intelligent IoT agents to perceive power outages in the station area needs to be improved

Embodiment 1

[0042] In order to solve the problems of delayed perception of power outage events and inaccurate statistics of power outage duration, the present invention provides a power outage perception method for station users based on intelligent IoT agents. achieved on a cooperative basis, such as figure 1 shown, including:

[0043] Step 1: Conduct batch polling and testing of the voltage values ​​of the smart meters of users in the station area;

[0044] Step 2: Use the feedback of the smart meter of each user in the station area to study and judge whether there is a power outage event for each user in the station area;

[0045] Wherein, when there is a power outage event for a user in the station area, at the moment when all the users who have the power outage event resume power supply, the power outage and power-on time recorded by the smart meter of the user who has the power outage event is called and measured, and the power outage event is calculated. The user's outage duratio...

Embodiment 2

[0073] Based on the same inventive concept, the present invention also provides a power outage perception system for station users based on an intelligent IoT agent. The basic structure of the system is as image 3 shown, including:

[0074] The batch polling calling and testing module is used for batch polling calling and testing the voltage values ​​of the smart meters of users in the station area;

[0075] The research and judgment module is used to use the feedback of the smart meter of each user in the station area to study and judge whether there is a power outage event for each user in the station area;

[0076] The calculation module is used to call and measure the power-off and power-on time recorded by the smart ammeter of the user who has the power outage event at the moment when the users who have the power outage event have all recovered power supply when there is a power outage event in the station area. The duration of the power outage for the user in which th...

Embodiment 3

[0098] The intelligent fusion terminal in the station area is installed in the power distribution room, box-type substation or comprehensive distribution box on the pole. The data of the smart meter is connected to the intelligent fusion terminal in the station area through the RS485 protocol. The transmission protocol is MQTT. To investigate the power-on situation, the specific steps are as follows:

[0099] Step S1: count the number of smart meters in the station area, and calculate the maximum number n of smart meters that can transmit information simultaneously when the communication is not blocked;

[0100] Step S2: according to the principle of batching, the smart meters of the users in the station area are batched;

[0101] Wherein, the batching principle is the basis of the maximum number n of smart meters that can transmit information at the same time, the geographical location of the smart meters in the station area, and the phase lines connected to the smart meters ...

Abstract

The invention provides a transformer area user power failure sensing method and a transformer area user power failure sensing system based on intelligent internet-of-things agency. The method comprises the following steps: carrying out batch polling interrogation on voltage values of intelligent electric meters of users in a transformer area; judging whether each user in the transformer area has a power failure event or not by utilizing the interrogation feedback of the intelligent electric meter of each user in the transformer area, wherein when there is a user power failure event in the transformer area, at the moment when all the users with the power failure event recover power supply, the power failure and power on moments recorded by the intelligent electric meters of the users with the power failure event are measured, and the power failure duration of the users with the power failure event is calculated. According to the method, the accuracy of sensing the power-off and power-on events of the users in the transformer area and calculating the power-off duration is improved, and the power supply reliability of the transformer area is improved.
