Supporting device for transient stability discrimination
专利汇可以提供Supporting device for transient stability discrimination专利检索，专利查询，专利分析的服务。并且PURPOSE: To discriminate stability quickly and correctly by a method wherein generators are divided into groups by the phase difference thereof and differences between respective average phases and average speed differences are compared to decide the step-out of a generator when the difference is higher than a predetermined value.
CONSTITUTION: The phase difference and speed difference of respective generators are taken from transient stability operating result 8 by a transient stability discrimination C12. Respective generators are classified by the phase thereof. The average phase and average speed difference of respective generator groups are operated to discriminate the stabilities and, then, discrimination is advanced to the stability discriminating group of next time step. When a phase difference between respective groups has exceeded a given value, the average speed differences between respective groups are referred. Knowledge in a knowledge base(KB) 13 is utilized and the stability discrimination is effected by an estimation engine 14. A rule, which decides that it is unstable when the phase and speed differences between respective generator groups have exceeded a given value, is utilized as the knowledge for discriminating by the knowledge base (KB)13. The stability may be discriminated correctly in a high speed.
