An object-oriented editing and correction method for psd power flow data and stable data

Abstract

The invention discloses a PSD (Power System Department) tide data and stable data editing and correction method based on object orientation and belongs to the field of data analysis of an electric power system. The PSD tide data and stable data editing and correction method comprises the following steps: establishing an element object, wherein the object comprises methods of converting attributes to PSD data, converting PSD data to attributes, newly establishing an element, adding the element into a stable calculation result output part, detecting element errors and correcting the element; providing an editing page for a user; and inquiring, modifying, updating and correcting the PSD data. By virtue of the PSD tide data and stable data editing and correction method, tide data, stable data and the stable calculation result output part are edited and corrected synchronously, and data invalidation or errors caused by manual errors are avoided; and the accuracy of the PSD data is enhanced, and the input efficiency and accuracy of the PSD data are improved.

Description

technical field [0001] The invention relates to the field of power system data analysis, in particular to an object-oriented PSD power flow data and stability data editing and correction method. Background technique [0002] PSD power system analysis program is a power system analysis software package developed by China Electric Power Research Institute. It includes multiple calculation programs such as power flow, stability, short-circuit current, and small disturbance calculation and analysis. It is widely used in power system analysis, planning and other fields. [0003] Power flow data and stability data are the two basic data for PSD analysis and calculation. The data filling needs to be carried out separately according to the card. When using it, it is necessary to fill in the power flow data, stability data, and stability calculation output corresponding to the component. Take the line component as an example: first Open the power flow file, fill in the names of the b...

Problems solved by technology

[0004] The operation of the traditional data filling process is repetitive, and the efficiency of a large amount of data entry process is low. It is easy to cause the parameters of the same component in different cards to be inconsistent due to human error, resulting in invalid or wrong parameters. Some cards of some components or some parameters in the card (such as Zero-sequence parameters of transformers) are allowed to be missing, and some parameters of some components have default values ​​(such as zero-sequence parameters of lines), so once the given parameters are invalid or wrong, it will not affect the calculation of PSD, and this use is invalid or It is difficult to detect the result of calculation with wrong parameters, which brings huge hidden dangers to the calculation work

[0005] The traditional method of filling in parameters is all text, which requires manual analysis. For example, the output selection of the stable calculation output part, the parameters to be filled in are numbers 0-7, and these 8 types indicate whether to output to 3 types of files, which is not intuitive
