Problems solved by technology

The change characteristics of the power grid equipment model are irregular, and the frequency of manual modification according to the equipment construction of the power grid is very low. Due to the large number of equipment in the distribution network, the modification frequency is slightly higher, so the general automation system does not save the model of the historical state. , with the maturity of big data technology, the value of historical data is gradually realized in the electric power field, hoping to analyze and dig out more valuable information from historical data. Although historical measurement data can be easily obtained, due to the inability to obtain historical The status of the power grid equipment model is limited in some analysis scenarios that need to combine the topology and parameters of the power network equipment

Embodiment 1

[0036] An embodiment of the present invention provides a method for constructing a time sequence of a power system static equipment model, such as figure 1 As shown, it specifically includes the following steps:

[0037] (1) Add effective time field and failure time field to the original model table to form a historical model table;

[0038] (2) copy the content in the original model table to the historical model table, and assign values ​​to the effective time field and the failure time field of each equipment model in the historical model table, and complete the initialization of the historical model table;

[0039] (3) In response to the external operation information, set the effective time field, expiration time field and / or content information of the equipment model corresponding to the external operation information in the historical model table, and complete the modification of the equipment model in the historical model table or delete.

[0040] In a specific implem...

Embodiment 2

[0070] Based on the same inventive concept as that of Embodiment 1, the embodiment of the present invention provides a time sequence construction device for a static equipment model of a power system, including:

[0071] Add unit, used to add effective time domain and failure time domain to the original model table to form historical model table;

[0072] The initialization unit is used to copy the content in the original model table to the historical model table, and assign values ​​to the corresponding effective time field and expiration time field, so as to complete the initialization of the historical model table;

[0073] The first processing unit is used to obtain the operation information of the original model table, set the effective time field, expiration time field and / or content information of the equipment model corresponding to the operation information in the historical model table, and complete the operation information in the historical model table Modification...

Abstract

The invention discloses a power system static equipment model time sequence construction method and device, and the method comprises the steps: adding an effective time domain and a failure time domain into an original model table to form a historical model table; copying the content in the original model table to the historical model table, and assigning the effective time domain and the failuretime domain of each equipment model in the historical model table to complete initialization of the historical model table; and in response to the external operation information, setting an effectivetime domain and a failure time domain of the equipment model corresponding to the external operation information in the historical model table, and completing modification or deletion of the equipmentmodel in the historical model table. According to the invention, the maintenance operation of the model table can be completely recorded, so that the model at any historical time can be quickly queried.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a method and device for constructing a time sequence of a static equipment model of a power system. Background technique [0002] In the automation system of the power system, it is often necessary to model the primary and secondary equipment of the power network, use the computer system to describe the information of the system management objects, and combine the dynamic measurement data to analyze and manage the operating status of the power system. The power dispatching automation system analyzes the equipment model by combining the current model and real-time data, and stores historical measurement information. When it is necessary to analyze the historical state of the power grid, because there are only historical measurement data and the equipment model only has the current state, it will cause analysis errors. The change feature of the measureme...
