Title: Equipment for detecting soundness or unsoundness of system at power supply side in non-utility power generating facility
Inventor: SOMEYA TAKEO
IPC: H02J3/38
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of accidents by accurately opening a linkage breaker, by judging whether a current supply side is sound or unsound from a change in electric energy calculated based on a current value and a voltage value detected at a current detecting section and a voltage detecting section, when a non-utility power generating facility is linked. SOLUTION: If a non-utility power generating facility side 10 is sound when surplus power from the non-utility power generator 22 is flowing reversely to the power supply side 10 and the power supply side 10 is sound, a predetermined current flows to an impedance load section 23 connected through a branch circuit 20a to a connecting point P2 at mid-point between the non-utility power generator 22 and a branch point P1. Also, if a linkage breaker 15 is opened because of a trouble at the power supply side 10, or power line 16 is broken and the power supply side 10 is unsound, a current flowing to the impedance load section 23 changes and decreases. Thus, whether the power supply side 10 is sound or unsound can be judged by detecting a change in a current flowing to the impedance load section 23.
