Problems solved by technology

[0003] However, the existing power system dynamic simulation tests all use manual system modeling, which requires a large workload and requires professionals to configure. The parameter configuration workload is relatively large, and a parameter configuration error will cause inaccurate testing of the entire system.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] This embodiment provides an automatic dynamic model test method for an intelligent substation based on an SSD file, which includes three steps.

[0022] The first step is the system automatic modeling method based on SSD files.

[0023] According to the description of the primary part in the SSD file, the primary system model of the smart substation is established. First, according to the Substation substation model, the basic information of the substation can be obtained: the name of this substation is Andou Substation, located in Fuzhou.

[0024] Secondly, according to the Voltage Level model, it can be obtained that the substation has two voltage levels, 220kV and 110kV. According to the bay model, it can be obtained that the 220kV voltage level has a 25B switch interval and a #1 main transformer interval (such as figure 1 shown); 110kV vol...

Abstract

The invention relates to an intelligent substation automatic dynamic simulation test method based on an SSD file. The method comprises the steps of firstly, automatically establishing a system model based on the SSD file; secondly, associating secondary equipment with a primary system according to the established system model; and finally, carrying out an automatic dynamic simulation standard test. According to the method, the dynamic simulation test difficulty of an intelligent substation can be reduced, an automatic test scheme is formed, and a test process can be standardized easily.

Description

technical field [0001] The invention relates to the field of automatic design of power systems, in particular to an automatic dynamic model test method for intelligent substations based on SSD files. Background technique [0002] The power system is a unified system of electric energy production, transmission and application transformation composed of power plants, power grids and electric loads. Power generation, transmission, and power consumption are continuous processes that are carried out and completed at the same moment. The electrical equipment in the power system is either directly connected or electromagnetically coupled to each other. The actual system test is very difficult. Most of the tests are carried out on the simulation model. The dynamic simulation of the power system is a physical simulation used to study the dynamic characteristics of the power system. In recent years, the application of computer software and hardware technology has made the power system...
