Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0031] Such as figure 1 As shown, the substation automatic modeling and simulation method based on the IEC 61850 SCD file reads the substation SCD file described in accordance with the IEC61850 standard, and parses it into a structure through the xml_io_tools toolkit in MATLAB. At the same time, MATLAB creates an Excel table for input parameters. After manually modifying the relevant parameters, MATLAB reads the Excel table and parses the structure to obtain the substation topology information and simulation model parameters, and then generates the .atp simulation file according to the rules of the .atp file.

Abstract

The invention discloses a transformer substation automatic modeling and simulation method and system based on an IEC 61850 SCD file. The method comprises the steps that a transformer substation SCD file described according to the IEC 61850 standard is read and analyzed into a structural body through xml_io_tools in a MATLAB, meanwhile, the MATLAB creates an Excel form for parameter inputting, and after related parameters in the Excel form are manually modified, the MATLAB reads the Excel form and analyzes the structural body, so that transformer substation topological information and simulation model parameters are obtained; then, a .atp simulation file is generated according to .atp file rules. Compared with a traditional manual modeling mode, the transformer station design and operating screw simulation difficulties are greatly lowered, operation conditions of a transformer substation can be accurately simulated on the condition that component parameters are selected appropriately, and the requirement for engineering practice is met.

Description

technical field [0001] The invention belongs to the field of automatic modeling and simulation of substations, in particular to a method and system for automatic modeling and simulation of substations based on IEC 61850 SCD files. Background technique [0002] The IEC 61850 standard is the only international standard for substation automation systems based on a common network communication platform. It solves the interoperability and protocol conversion problems of substation automation system products, making the engineering implementation of smart substations standardized, unified and transparent. No matter which system integrator builds the smart substation project, the structure and layout of the entire substation can be understood through the system configuration file. [0003] IEC 61850-6 defines the substation configuration description language (Substation Configuration Language, SCL). The SCL language describes the primary equipment, substation communication, second...
