Title: Control device for electric propelling apparatus
Inventor: ICHIKAWA HIROAKI
IPC: B63H23/24
Filed: 1978-05-10
Abstract: PURPOSE: To provide a control system for electric propelling apparatus, which is capable of preventing step-out of the propelling apparatus at the time of acceleration and deceleration by limiting variation fuel supply rate to the internal combustion engine when speed difference of AC generator and synchronous motor exceeds a certain value.  
     CONSTITUTION: If speed instruction Sp is increased at the time of acceleration, opening of control valve DA is increased by controller CR and fuel supply rate to gas turbine GT is increased so that revolving speed of gas turbine GT is increased. Under such circumstance, if deviation of the speed of AC generator G and synchronout motor SM exceeds a prescribed value ΔSL, output is given from limiter LT and added with output of rectifier RE, and the sum of these outputs is compared with said speed instruction SP. Although rapid increase in the output of limiter LT tends to reduce opening of control valve DA controller CR, output of limiter LT is becomes zero if speed of synchronous motor SM is increased in this while. Thus, speed of gas turbine GT is controlled within the limit value ΔSL of limiter LT and acceleration characteristics of the synchronous motor SM, so that step-out of the synchronous motor SM and AC generator G can be prevented by selecting ΔSL at an appropriate value.
