Embodiment Construction

[0021] For step 1, construct the component coordinate analysis function to realize the analysis of the coordinates of each component in the PSCAD component library, and calculate the coordinates of all external nodes of the component by giving the reference coordinates and directions. Specific embodiments are as follows.

[0022] Step 1 is the pre-analysis step of the topology analysis model of the PSCAD simulation model, which is aimed at the analysis of the components in the component library included in the PSCAD simulation software. For the components in the component library, a typical component is taken as an example to illustrate, and the definitions of its reference coordinates, directions and external nodes are as attached figure 1 shown.

[0023] attached by figure 1 It can be seen that the component has a reference coordinate marked as a circle, and three external coordinates marked as a box.

[0024] According to the component properties, it can be seen that the...

Abstract

The invention provides a topology analysis method of a PSCAD (Power System Computer Aided Design) simulation model. The method comprises the steps of constructing an element coordinate analysis function, realizing analysis of coordinates of each element in the PSCAD element library, and calculating coordinates of all external connection nodes of the elements by giving reference coordinates and directions; constructing a file information extraction function, reading a PSCAD simulation model file, and extracting element parameters and element actual coordinates used in the model; constructing anelement topology analytic function, summarizing actual coordinates of the elements, defining each coordinate as a node, and obtaining node serial numbers of all external connection nodes of differentelements; and outputting the parameter information and the node serial numbers of all the elements to obtain the parameters of all the elements, obtaining the corresponding positions of different elements through the node serial numbers, and combining the parameter information and the node serial numbers to realize topology analysis of the PSCAD simulation file. According to the method, datamation can be effectively carried out on the PSCAD graphical simulation model, and direct data utilization is facilitated.

Description

technical field [0001] The invention relates to an analysis method of a PSCAD simulation model, in particular to a topology analysis method of a PSCAD simulation model. [0002] technical background [0003] PSCAD simulation software is a dedicated simulation software for power systems. Through an excellent graphical interface, users can use components in the component library or various custom components to realize simulations in various fields of power systems. After the simulation model is built, the PSCAD simulation software uses the time-domain analysis method to solve the model, which has the advantages of high simulation precision and accurate conclusions. Since the solution method of PSCAD simulation software is fixed, if the user needs other solution methods for calculation, or to verify the correctness or effectiveness of other solution methods, no direct comparison can be made. By analyzing the PSCAD simulation model file, the parameters and topological structure ...
