Results obtained in this project are as follows.(1) From the simulation results performed on the one-machine connected to an infinite bus model system, it is concluded that the effect of SFCLs, in which two SFCL devices are connected in parallel, on the enhancement of transient stability is significant also in the case of unsuccessful reclosing. In addition, SFCLs may make it possible to extend the dead time of circuit breakers so that the possibility of unsuccessful reclosing becomes lower.(2) From the simulation results performed on the two-machines connected to an infinite bus (9 nodes) model system, it is concluded that the fault currents can be limited by SFCLs with shunt resistance value greater than 0.6 pu, the power system transient stability can be enhanced effectively by SFCLs with shunt resistance value of 1.1 pu, and that the turbine shaft torsional torque oscillations can be suppressed effectively by SFCLs with shunt resistance value of 0.8 through 1.1 pu. Therefore it may … More be considered that the optimal value of shunt resistance in SFCLs for the two-machines connected to an infinite bus (9 nodes) model system is 1.1 pu.(3) From the simulation results performed on the JIEE WEST 10 Machines model system, it is concluded that the fault currents can be limited by SFCLs with shunt resistance value greater than 0.6 pu, and that the power system transient stability can be enhanced effectively by SFCLs with shunt resistance value of 1.1 through 2.0 pu. Therefore it may be considered that the effective value of shunt resistance in SFCLs for the JIEE WEST 10 Machines model system is from 1.1 through 2.0 pu.(4) Quantitative evaluation method of transient stability and determination method of optimal reclosing time for circuit breakers in multi-machine power system are studied by using 3 model systems; i.e., one-machine connected to an infinite bus model system, two-machines connected to an infinite bus (9 nodes) model system, and JIEE WEST 10 Machines model system. As a result, it is concluded that the transient stability of multi-machine power system can be evaluated by using the summation of kinetic energy of each generator, and that the moment at which the total kinetic energy becomes minimum is almost optimal for reclosing from a point of view of stability enhancement.

本项目取得的成果如下。(1)从一个机器连接到一个无限大的总线模型系统上进行的仿真结果，它的结论是SFCL的效果，其中两个SFCL设备并联连接，对增强暂态稳定性是显着的情况下，也不成功重合闸。此外，SFCL可以延长断路器的死区时间，从而降低重合闸失败的可能性。(2)通过对两机接入无穷大（9节点）模型系统的仿真，得出并联电阻值大于0.6 pu的SFCL可以限制故障电流，并联电阻值为1.1 pu的SFCL可以有效地提高系统暂态稳定性，分流电阻值为0.8 ~ 1.1 pu的SFCL能有效抑制涡轮机轴系扭矩振荡。因此其可能 ...更多信息 对于两机连接到一个无限大母线（9节点）模型系统，SFCL的并联电阻的最佳值为1.1 pu。(3)通过对JIEE WEST 10机模型系统的仿真，得出并联电阻值大于0.6 pu的SFCL可以限制故障电流，并联电阻值为1.1 ~ 2.0 pu的SFCL可以有效地提高电力系统的暂态稳定性。因此，可以认为JIEE WEST 10机器模型系统的SFCL中的分流电阻的有效值为1.1至2.0 pu。(4)采用3个模型系统，即：一台机器连接到无限总线模型系统，两台机器连接到无限总线（9节点）模型系统，以及JIEE WEST 10台机器模型系统。结果表明，多机电力系统的暂态稳定性可以用各发电机的动能之和来评价，从提高稳定性的角度看，总动能最小的时刻几乎是重合闸的最佳时刻。少
