Problems solved by technology

For a small system, it is feasible to manually fill in the data, but for a large-scale system, if you fill in the data manually, it will not only consume a lot of manpower and material resources, but also increase the possibility of errors

Embodiment Construction

[0034] Such as figure 1 As shown, a power grid power flow model conversion tool includes a model import module 1, a memory management module 2, an adapter management module 3 and a model export module 4, wherein the adapter management module 3 includes a BPA adapter that matches the BPA model 31, a CIM adapter 32 matching the CIM model, an E-text adapter 33 matching the E model, etc.

[0035] The conversion method of above-mentioned grid power flow model conversion tool, comprises the steps:

[0036] step 1: Each external model data is imported into the grid power flow model conversion tool through the model import module 1 .

[0037] Step 2: According to the power system modeling principle, establish their respective memory banks through the memory management module 2; the hierarchical model of the memory bank is divided into the following five layers: as figure 2 As shown, the first layer is the regional layer as the main area of ​​research, which is commonly known as...

Abstract

The invention discloses a conversion tool and method for a power flow model of a power grid. The conversion tool comprises a memory management module, an adapter management module, a model import module and a model export module, wherein the adapter management module comprises a BPA adapter matched with a BPA model, a CIM adapter matched with a CIM model, an E text adapter matched with an E model, and the like. By using the conversion tool and method for the power flow model of the power grid, different types of power grid models are read offline, the data are automatically mapped and converted, and a set of power flow calculation data capable of being analyzed stably is formed. The formed power flow data is basically consistent with those of the working condition of a real simulated power grid run on the power grid, meanwhile, the tool guarantees the integrity of the analyzed power grid, and the requirements of stable analysis for the level of details of modelling of the power grid are met.

Description

technical field [0001] The invention relates to a power grid power flow model conversion tool and a conversion method thereof, belonging to the field of electric power data processing. Background technique [0002] The energy management system (EMS) data of dispatching centers at all levels generally constructs their own power system models according to their own needs or adopts recognized system model standards. When modeling power systems in China, CIM models and grid model E languages ​​are generally used. Off-line analysis software adopts BPA model or private model, etc. [0003] Power system CIM (Common Information Model) is a standardized EMS system model formulated by the 57th subcommittee of the IEC Technical Committee, called IEC-61970. CIM is an abstract model that represents all the main objects of the electric power enterprise included in the EMS information model. By providing a standard way of representing power system resources with object classes and attrib...
