Therefore, the embodiment provides an automatic alarm method for transformer load rate based on a D5000 power grid dispatching system, which increases an automatic alarm function for transformer load rate on the basis of the D5000 power grid dispatching system, and the automatic alarm method, as shown in fig. 1, includes the following steps:
s1: periodically acquiring and storing real-time load rate data of a transformer in a D5000 power grid dispatching system;
s2: acquiring load rate data corresponding to the transformer at the same time yesterday;
s3: subtracting the real-time load rate data from the load rate data corresponding to the same time of yesterday to obtain a load rate difference value;
s4: judging the working states of the transformer at present and yesterday according to the real-time load rate data and the load rate data corresponding to yesterday at the same moment;
s5: and starting/not starting the alarm according to the load rate difference and the working state of the transformer today and yesterday.
According to the alarming method provided by the embodiment, the real-time load rate of the transformer is periodically acquired, yesterday transformer load rate historical information is acquired, the periodic comparison is carried out on the yesterday load rate deviation of today, abnormal difference of the transformer load rate can be visually displayed through a human-computer interface of the D5000 power grid dispatching system, operation and maintenance monitoring personnel are prompted to pay attention to the abnormality as soon as possible, potential fault risks of the power system are found, handling is carried out as soon as possible, potential safety hazards are avoided, and safe and reliable operation of the power grid is guaranteed.
In addition, the conditions of maintenance, power failure non-working state and the like can be intelligently judged in the alarm method, the condition of load rate deviation abnormity caused by transformer power failure, maintenance and the like is eliminated, the interference to operation and maintenance personnel is reduced, and the accuracy of the load rate statistical result of the electrical equipment of the transformer substation is improved.

s202: and calling a sampling query service, packaging the data of the sampling query into a self-defined structure body, and storing the data into a historical data vector container.

The function module analyzes the returned result according to a specified format, packages the data into a self-defined structure body, and stores the data into a historical data result vector container (historical data vector container for short), and the subsequent logic processing unit performs subsequent processing on the container.

Step S4: according to the real-time load rate data and the load rate data corresponding to the same moment of yesterday, the specific process of judging the working state of the transformer at the present day and yesterday is as follows: the transformer is judged to be in a working state or in a non-working state such as maintenance and power failure by identifying information such as a measured value, a measurement state, a quality code and the like corresponding to the real-time load rate data and the load rate data at the same time of yesterday, so that the condition that the load rate deviation is abnormal due to the power failure, the maintenance and the like of the transformer is eliminated.
Step S5: according to the load rate difference value and the working states of the transformer today and yesterday, the process of starting/not starting the alarm specifically comprises the following steps: comparing the load rate difference with a threshold value, and starting an alarm when the load rate difference is greater than the threshold value and the transformer is in a working state today and yesterday; otherwise, no alarm is started.
In practical application, the threshold is set to 20%, at this time, if the load rate difference is less than 20%, no relevant processing is performed, and if the load rate difference is greater than 20%, an alarm and real-time library updating are performed.
The specific process is as follows: firstly, packaging the content according to an alarm service specification, then calling an alarm service client interface, introducing the packaged structure as an input parameter into the client interface, sending the alarm content to a service terminal for processing and warehousing, wherein the alarm content comprises out-of-limit time, a load rate value of today, a load rate value of yesterday at the same time, and a real-time load rate and a yesterday history difference value. And calling the record with the load rate difference value of more than 20% between the current day and the yesterday to a real-time library service for updating or writing, and quickly checking the transformer information with the load rate difference value exceeding the limit value from the real-time library.
