Abstract

The invention discloses a fault handling plan online checking parallel computing method, which comprises the steps of obtaining power grid real-time operation mode data and X sets of plan files to bechecked in a power system, and performing filtering and screening; for the N sets of screened plan files meeting the requirements, issuing key information to a management platform side by utilizing adata transmission service; forming post-fault mode data corresponding to each plan on the management platform side, performing task distribution and scheduling according to the number of the computingnodes, and dynamically distributing the post-fault mode data of the plan to each computing node; at the computing node side, carrying out monitoring and controlling for each issued plan checking andanalyzing task; returning a result of each plan check analysis task to the management platform side; and at the application server side, recycling and summarizing the result of each plan check analysis task. According to the method, the timeliness of plan analysis can be improved, the power grid analysis and calculation period is shortened, the practicability of a fault handling plan online checking system is improved, and safe and stable operation of a power grid is better guaranteed.

Description

technical field [0001] The invention relates to a parallel computing method for online checking of fault handling plans, and also includes a parallel computing system. Background technique [0002] With the expansion of power grid scale, the increase of complexity, and the access of new energy sources, the operation mode of the power grid is changing. The traditional way of relying on manual preparation of fault handling plans has a large workload, long preparation time, and calculation results that cannot be adapted to real-time methods. Many questions. Therefore, "A Method and System for On-line Checking and Intelligent Control of Fault Disposal Plans" was proposed, but this method adopts the serial calculation mode, taking 1 to 2 minutes for each plan analysis and checking calculation as an example, when the power grid When the number of fault handling plans is large (there are often hundreds or even thousands of fault plans in a typical mode), it will lead to a long cal...
