Problems solved by technology

In the past, power outages of distribution transformers mainly depended on users complaining to the power department after the power outage, and the confirmation could only be confirmed after the emergency repair personnel arrived at the distribution station area. This kind of passive emergency repair not only takes a long time to recover, but also has poor user satisfaction.
At present, the more advanced method is to report power outage events through the public transformer concentrator, but the reported information of power outage events received by the acquisition master station contains too much invalid information, such as false alarms caused by voltage instability and frequent reports of power outage information, occupying the master station resources, affecting other businesses of the collection master station system, and even affecting the timely handling of power outages in effective stations

Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a concentrator with the function of reporting power failure events is installed at the outlet of the low-voltage side of the 10KV transformer. The concentrator reports information to the master station through the wireless public network. The master station has the function of receiving the report from the concentrator. User electric meter, general meter of station area. Only one concentrator is installed in each station area.

[0028] The present invention utilizes the concentrator to monitor voltage abnormalities to screen effective power outage information, such as figure 2 As shown, the optimization method includes the following steps:

[0029] Step 01: The concentrator is running normally;

[0030] Step 02: Monitor whether the concentrator voltage is lower than the critical vol...

Abstract

The present invention relates to the field of power grids, and particularly relates to an optimization method for active reporting of a power failure event concentrator in a transformer area. The method of the present invention uses a concentrator to monitor a voltage anomaly for screening effective power failure information. After the concentrator monitors the voltage abnormality, the concentrator collects a set of concentrator AC sampling voltage again. After a power failure event is determined initially, the power failure event is recorded and the total meter voltage in a transformer area is interrogated actively. After the power failure event in the transformer area is judged initially, the power failure event is reported to a master station. After a collecting master station receivesthe power failure event, the total meter voltage in the transformer area is copied for secondary judgment. If the power failure event in the transformer area is also determined in the secondary judgment, the master station sends the power failure event to a distribution network repair platform to arrange corresponding repair working personnel. The method of the present invention can improve the reliability of reporting the power failure event in the transformer area, save the resources of the master station, and strive for the time for the repair work of power failure.

Description

technical field [0001] The invention relates to the field of electric power grids, in particular to an optimization method for active reporting of power outage event concentrators in station areas. Background technique [0002] The distribution station area is an intermediate link connecting the high and low voltage power grids. The distribution transformer is the source of power for low-voltage power users. Once the distribution transformer fails, it will directly cause all users in the station area to be unable to use electricity. Therefore, it is particularly important to strengthen the monitoring of power outage events in the Taiwan area, rush to the scene for emergency repairs immediately after the power outage of the distribution transformer, and shorten the power outage time of users as much as possible. In the past, power outages of distribution transformers mainly relied on users to complain to the power department after the power outage, and the emergency repair pe...
