Embodiment Construction

[0113] On the basis of the existing power system synthesis program (PSASP), the software developed by adopting the method of automatic batch generation of fault sets based on the three lines of defense is as follows:

[0114] (1) System structure:

[0115] 1. Functional structure:

[0116] The schematic diagram of the envisioned resection scheme in static security analysis is as follows: figure 1 shown. For static safety analysis calculations, based on the existing N-1 calculation settings and specific resection scheme settings, the function of automatically generating batch N-M resection schemes is provided.

[0117] The schematic diagram of expected fault set in transient safety analysis is as follows: figure 2 shown. For transient safety analysis, based on the existing fault set and fault template settings, the type of fault template is added, and the rules for generating batch faults are added in the fault set.

[0118] 2. Technical structure:

[0119] The software ...

Abstract

The invention provides a classified fault template based on the concept of three lines of defense in a power system, which is generally adopted by power grid construction in China. On the basis, the automatic batch fault set generation is realized and the batch generation with same faults can be realized for a plurality of nodes in the same region or same voltage grade. Compared with a traditional single fault generation method for elements, the automatic batch fault set generation method can be used for saving multiple repeated operations, so that the time for fault generation is greatly saved and the work efficiency is improved. Meanwhile, various fault templates are classified according to the requirement of three lines of defense, thus weak spots and safety and danger points in the operation of the power grid can be found more comprehensively and accurately, and further, references can be provided for safe and stable operation of a large power grid.

Description

technical field [0001] The present invention relates to the field of power systems, in particular to a method for automatically generating fault sets that provide fault modes for power system dynamic security analysis, and more specifically, an automatic batch generation method for fault sets based on three lines of defense. Background technique [0002] Conducting experimental research on the actual power grid will bring harm to the safe and stable operation of the power grid and personal safety. Unreasonable and imperfect design of the test program may lead to grid safety and stability accidents; improper human operation may cause personal injury and death. In addition, conducting experimental research on the actual site often requires high site requirements and complicated wiring, resulting in high test costs. Various factors show that the establishment of an all-digital real-time simulation laboratory, moving secondary equipment such as physical devices into the laborat...
