Abstract

The invention discloses a Petri network-based leakage protection setting calculation method for a mine high-voltage power network, which is mainly applied to an automatic setting calculation of leakage protection of the mine high-voltage power network. According to the method, a colored Petri network-based network topology analysis model and a colored Petri network-based leakage protection setting calculation model are built; the network topology analysis model comprises eight places and five changes, and mainly finishes topology analysis of the mine high-voltage power network and encoding on each switch; and the leakage protection setting calculation model comprises eight places and seven changes, and mainly finishes the setting calculation of the leakage protection of the mine high-voltage power network. A system is modeled by a colored Petri network, so that the modeling difficulty is lowered; the model is simplified; the hierarchy is high; the inference is simple; and the setting calculation accuracy and rapidity are effectively improved.

Description

technical field

[0001] The invention discloses a mine high-voltage power grid leakage protection setting calculation method based on Petri net, and belongs to the coal mine high-voltage power supply network leakage protection setting calculation field. Background technique

[0002] Petri net is a very good modeling tool for discrete event dynamic systems. It can effectively describe the network topology and the synchronization, concurrency and other behaviors in the system. It has been well used in power system fault diagnosis and other power fields. As a kind of advanced Petri net, colored Petri net uses color to represent resources with the same characteristics, and distinguishes them by tokens of different colors, which can greatly simplify the structure of Petri net and enhance the versatility of the model. When performing topology analysis on the mine high-voltage power grid, the search traversal algorithm and the analysis method based on the correlation matrix are main...
