A Method of Predictive Fault Set Generation Based on Plant and Station Wiring Information

Abstract

The invention discloses a plant wiring information based anticipatory fault set generation method. The method comprises the steps of (1) determining whether a plant wiring information maintenance database is required; (2) determining whether equipment belongs to a to-be-generated voltage level fault subset according to certain substation equipment name number information in power grid models, storing the plant wiring information of the equipment into a fault set database if the equipment belongs to the subset, adding calculation identification position to all line information, and setting the calculation identification position to be 0; (3) setting different fault cars to different equipment in the fault set database; (4) stopping in the step (3) if certain voltage level fault subset is to be generated, and repeating (2) to (3) if a full voltage level fault subset is to be generated. The method has the advantages that anticipatory fault sets are generated rapidly, efficiently and automatically, fault setting time is reduced, and the workload is reduced for subsequent calculation and analysis.

Description

technical field [0001] The invention relates to a method for generating an expected fault set based on power station wiring information, and belongs to the field of power system simulation analysis and calculation. Background technique [0002] With the continuous increase of the scale of the power system, the continuous advancement of the power market operation mechanism, and the gradual integration of renewable energy power generation, the security and stability of the power system has become an urgent need and development direction for power system operation and scheduling. This is an urgent need for power system simulation calculations. Setting a large number of expected faults is the premise of power system simulation calculation, but the previous setting of expected faults generally relies on the experience of power grid dispatching operators, and the workload is huge, which makes the manual writing process prone to errors; If we work together, it is inevitable that t...

Setting a large number of expected faults is the premise of power system simulation calculation, but the previous setting of expected faults generally relies on the experience of power grid dispatching operators, and the workload is huge, which makes the manual writing process prone to errors; If we work together, it is inevitable that there will be problems of omission, wrong compilation, and repeated compilation. However, it is difficult to detect such problems because the fault set data cannot be structured; Get rid of the dependence of the setting of expected fault set on the experience of power grid dispatching operators

The invention patent of "Automatic Generation Method and Device of Power Grid Fault Set" with the application number of 201110375256.7 mainly uses real-time information of the power grid, but in actual work, due to the strong confidentiality of the real-time information of the power grid and the large amount of data, it is difficult for other institutions except the dispatching center to promotion, the vast majority of power grid simulation calculation personnel still use offline data

In addition, because the structure of the power grid and the shutdown status of generators change in real time, and the simulation calculation often takes a long time, the so-called "real-time data" also becomes "offline data" in the calculation, so the calculation of offline data will be in the future Work will still be dominant
