一种检查同期回路接线的新方法

A new method of synchronized-voltage verifying

印度尼西亚一国际工程机组无启备变设计,因厂用电的单一性而导致无法实施发变组零起升压试验。在机组整套启动前,通过解除发电机引出端与封闭母线的连接,改变运行方式实现并列点两侧的电压互感器同电源核相,可以较好地解决此问题,且能够节省机组整套启动的试验时间,简化整套启动试验内容,具有一定的经济性。

There is no start-up standby transformer design in an Indonesia international project, the voltage of generator-transformer group can not be boosted from zero due to the fragility of the auxiliary power. However, this problem can be solved by disconnecting generator outlet terminal and isolated-phase busbar （ IPB ） before the startup of unit and then verifying the sequence and polarity of generator-transformer group as described above, which can also shorten the testing time and simplify the test content for the startup of unit in an economical way.
