Embodiment Construction

[0034] The present invention will be further described below in conjunction with drawings and embodiments.

[0035] A kind of method that PSASP data model is converted into RSCAD data model, concrete steps are as follows:

[0036] Step 1: Read the static component data and dynamic parameters in the .MYD format of the PSASP software to obtain component topology and component parameter information;

[0037] Step 2: Use C# language to analyze the above data in MYSQL format, and implement layering and network modularization of components according to data groups, substations and power plants;

[0038] Step 3: According to the actual simulation requirements, select the data group and retrieval method on the interactive man-machine interface, and determine the module or bus to be converted; at the same time, set the RSCAD page size and the storage of the converted output file according to the number of selected modules on the interface Location;

[0039] Step 4: Use the layout met...

Abstract

The invention discloses a method for converting a PSASP data model into an RSCAD data model, and the method achieves the automatic conversion of a PSASP electromechanical transient data into an RSCAD electromagnetic transient model, thereby achieving the high-efficiency and accurate simulation analysis of a large-scale AC/DC power system. The method avoids the heavy workload of parameter conversion and data input during the manual RSCAD modeling, and improves the efficiency and accuracy of RTDS real-time digital simulation. The method is simple in operation, and can flexibly select a network and model which need to be converted. The conversion result achieves the connection of complex topological structures between elements. The method employs a data graph visualization method based on a force-directed model for automatic layout, and a double-layer layout method is employed for layout, thereby preventing the direct connection of buses from causing a complex topological structure, and greatly facilitating the subsequent processing.

Description

technical field [0001] The invention relates to the field of power system simulation software, in particular to an automatic conversion method from PSASP to RSCAD data and models. Background technique [0002] With the development of computer hardware technology and communication technology, power system digital simulation has made a breakthrough, and powerful digital simulation software has appeared one after another. At the same time, FACTS controllers, DC transmission controllers, relay protection devices and safety and stability monitoring equipment are widely used in AC and DC interconnected power grids. These control systems must be tested and verified through real-time simulation before they can be put into actual power grid operation. Therefore, the test and inspection of automatic devices must require real-time simulation. RTDS is a real-time digital electromagnetic transient simulation system adopted by my country's electric power management and research departmen...
