Title: Supporting device for transient stability discrimination
Inventor: TAGUCHI YASUHIRO
IPC: H02J3/24
Filed: 1989-09-29
Abstract: 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.

Title: Method for manufacturing fiber reinforced composite electric wire
Inventor: NAGANO KOJI
IPC: H01B13/02
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To uniformize a structure of an Al-covered layer, and to avoid a crack and reduction in a looseness degree caused by a heat cycle by performing heat treatment for forming a structure of an Al layer or an Al alloy layer as a recrystallization structure before and/or after a stranding process of intertwisting plural strands. SOLUTION: After setting a bundled SiC/Al strand 26 in an electric furnace provided with an induction heating coil, heat treatment not less than five minutes is performed at a temperature not less than 300 deg.C for wholly recrystallizing a structure of an Al-covered layer 29 of the SiC/Al strand 26. After the heat treatment, the SiC/Al strand is taken out of the inside of the electric furnace to observe a sample cut longitudinal sectional structure, and when the heat treatment is incomplete, the heat treatment is performed again. Since prescribed heat treatment is performed before a stranding process, a structure of the Al-covered layer 29 in an SiC/Al composite electric wire becomes almost wholly a uniform structure to eliminate the occurrence of a 'crack' in the Al-covered layer 29 at heat cycle time.
