CONNECTING METHOD OF INDUCTION GENERATOR, INDUCTION GENERATOR SYSTEM AND BLOCKER

摘要

PROBLEM TO BE SOLVED: To efficiently use blockers in order to limit a rush current in the case of connecting an induction generator to a power system without using a reactor.;SOLUTION: This induction generator system 100 is connected to a power transmission line 10, and includes the blockers 1, 2, a timer 9 and an induction generator IG. The power transmission line 10 is a three-phase power transmission line, and composed of power transmission lines 10a, 10b and 10c. The blocker 1 includes connecting points 3, 4 and 5. The blocker 2 includes connecting points 6, 7 and 8. Terminals Ta, Tb and Tc are arranged at the induction generator IG. The terminals Ta, Tb and Tc are connected to the power transmission lines 10a, 10b and 10c, respectively, via the blocker 1 or the blocker 2. Each connecting point is in an open state at an initial stage, but when the induction generator IG is connected to the power transmission line 10, the connecting points 3, 4 and 5 are closed by the operation of the blocker 1 which is firstly conducted, and the connecting points 6, 7 and 8 are closed by the operation of the blocker 2 which is conducted after the lapse of a prescribed time by the control of the timer 9.;COPYRIGHT: (C)2008,JPO&INPIT
