HYBRID ELECTRIC POWER DEVICE FOR CRANE AND CONTROL METHOD OF HYBRID ELECTRIC POWER DEVICE FOR CRANE

摘要

THERE IS PROVIDED A HYBRID ELECTRIC POWER DEVICE FOR A CRANE AND A CONTROL METHOD OF NHE HYBRID ELECTRIC POWER DEVICE FOR THE CRANE MAC ENABLE NO PREVENT, DEGRADATION OF FUEL CONSUMPTION CF AN ENGINE GENERATOR EVEN IF LOAD SUDDENLY INCREASES. [MEANS FOR SOLVING PROBLEM] A HYBRID ELECTRIC POWER SOURCE DEVICE 1 FOR A CRANE INCLUDING AN ENGINE GENERATOR 10, AN ELECTRIC POWER ACCUMULATING UNIT 40, AND A CONTROL UNIT 2 FOR CONTROLLING THE ENGINE GENERATOR 10 AND THE ELECTRIC POWER ACCUMULATING UNIT 40, WHEREIN THE CONTROL UNIT 2 INCLUDES AN ELECTRIC POWER LOAD CALCULATING PART 2A WBIICH ACQUIRES ELECTRIC POWER LOADED ON THE ENGINE BASED ON REQUIRED ELECTRIC POWER SUPPLIED TO AN OUTSIDE AND CHARGING ELECTRIC POWER OF AN ELECTRIC POWER ACCUMULATING UNIT 40 AND A COMMAND SIGNAL SENDING PART 2B WHICH CALCULATES OUTPUT TORQUE AND A REVOLUTION SPEED BASED ON THE ELECTRIC POWER LOADED ON TRIE ENGINE CALCULATED BY THE ELECTRIC POWER LOAD CALCULATING PART 2E AND GENERATES A TORQUE COMMAND SIGNAL AND A REVOLUTION SOEED COMMAND SIGNAL.
