PURPOSE:To improve reliability of parallel operation of motor-generators, by providing a function for comparing load condition signals of other machines operating in parallel and judging whether a machine should be interrupted selectively. CONSTITUTION:When parallel operation of three motor-generators MG1...MG3 is confirmed, load bearing detectors D1...D3 compare power signals fed from power detectors C1...C3 with power signals fed from adjoining motor-generators. Motor-generators bearing load abnormally are selected from the comparison results and then interrupted selectively from parallel operation through controllers A1...A3. |
