Title:
再生エネルギー型発電装置及びモータコントローラ並びに再生エネルギー型発電装置の運転方法
Document Type and Number:
Japanese Patent JP6314112
Kind Code:
B2
Abstract:
A power generating apparatus of renewable energy type (1) includes: a rotatable rotor (5); a hydraulic pump (12) configured to be driven by the rotor (5) to pressurize working fluid; a hydraulic motor (14) configured to be driven by the working fluid from the hydraulic pump (12); a high-pressure fluid line (16) and a low-pressure fluid line (18) connecting the hydraulic pump (12) and the hydraulic motor (14); a generator (20) connected to a grid (50) and configured to be driven by the hydraulic motor (14); and a controller (48). The hydraulic motor (14) includes high-pressure (96) and low-pressure (98) valves for switching a communication state between the low-pressure (18) or high-pressure (16) fluid line and each of working chambers (93) formed by cylinders (91) and pistons (92) which reciprocate in conjunction with a rotation shaft (15). The controller (48) is configured to close, for the working chamber (93) corresponding to the piston (92) moving downward from a top dead center toward a bottom dead center among the pistons (92), the high-pressure valve (96) before the piston (92) moving downward reaches the bottom dead center, at the time of occurrence of a failure event of the grid (50).
