Abstract

The invention provides a method for quickly accelerating asynchronous parallel computation of transient stability based on a single-machine multiple-core hardware architecture, comprising the following steps: (1) realizing the batch, parallel batch, automatic load balancing batch computation of transient stability faults in fault sets, carrying out discriminatory analysis on the stability of each fault computation result, and drawing up a statistic analysis statement for fault computation results in all the fault sets; (2) carrying out batch computation and analysis on the transient stability work; and (3) providing a transient stability batch computation dead prevention method, realizing a process speed control method for parallel batch computation speed, and providing and realizing an implementation technique method combining the transient stability interactive computation and the transient stability automatic computation. The parallel batch computation is realized on the basis of the task decoupling mode without changing the transient stability computation algorithm and implementation form, the transient stability computation independence is guaranteed and the transient stability computation efficiency is improved, while the massive fault computation and the parallel computation are realized.
