Description

technical field [0001] The invention relates to a method for automatically generating BPA calculation files based on measured topology and measurement data, which is applied in the electric power industry and is used for generating BPA calculation files for power flow calculation and stability check calculation. Background technique [0002] The power industry needs to use the BPA calculation program in the power flow calculation and stability check calculation, and the BPA calculation program needs the BPA calculation file, namely the power flow calculation file and the stability calculation file. In actual work, it is necessary to write calculation files for thousands of grid components to describe the grid topology, load, and faults, and to determine the best mode of grid operation through combined calculations of various schemes. The traditional method of generating BPA calculation files has the following problems: [0003] 1. Writing calculation files by hand is heavy ...

AI Technical Summary

Problems solved by technology

[0003] 1. Writing calculation files by hand is heavy workload and low efficiency. It takes 4-5 hours for an analyst to complete an accurate power flow calculation, and 3-5 days to complete a special calculation;

[0004] 2. Based on the calculation file used in the previous work, use it as a template for partial modification. In the modification process, in order to reflect the correct power grid topology, it is manually compared with the EMS (Energy Management System) system or other business systems. low efficiency;

[0005] 3. Various electrical parameters and corresponding power distribution on the grid components are compared and modified manually with the data of the measurement system, so as to calculate various possible methods, but this work is heavy and inefficient;

[0006] 4. Since the power grid management is managed in a layered and partitioned manner, changes in the grid model in non-local jurisdictions cannot be reflected in the BPA calculation parameter file in a timely manner, and the equivalent method is often used to simplify, which cannot reflect the changes in the power grid in the jurisdiction. Details of the impact on the grid;

[0007] 5. When the new equipment is put into production and the old equipment is decommissioned, the topology change and electrical parameter change caused by it also need to be modified manually, and there is also a large manual workload

[0008] The above situation has been unable to adapt to the modern management requirements of the electric power industry
