Abstract

PURPOSE: To prevent sudden increase as well sudden decrease of load at frequency changing, by limitting of coefficient of fluctuation in slowing direction of speed signal.
CONSTITUTION: Actual speed signal N detected by speed detector 15 is conveyed to attenuation factor limitting section 60. At attenuation factor limitting section 60, when speed is under follow-width and moreover acceleration rapidly drop under set value, put out power for to slow down acceleration in set value rate. Speed signal N' which is limitted its attenuation factor, is compared with set speed signal N0, at comparison section 32. In function-generator 70, when speed increased and ΔN exceed ΔN1, at that time ΔN'=ΔN and regarded as constant and if ΔN becomes ΔN2, it is regarded ΔN'=ΔN-(ΔN2-ΔN1). By giving such character, when speed deviation is in ΔN1WΔN2, it can be possible to make it fixed turbine out put power regardless of speed variation.
