Patent
Wind Turbine Generator System
TL;DR: In this article, a phase difference and an amplitude difference between the grid voltage and the stator voltage of one phase of a winding are obtained to shorten a startup interval to reach a synchronizing condition, and the calculated compensation phase compensation value is used as an initial value for synchronizing at the next synchronizing operation.
Patent
Wind power generation system
TL;DR: In this article, the PWM-control provides for each phase a control paused period in which no overlap occurs, thereby generating high and low density in an inter-phase pulse.

Rion Takahashi,H. Kinoshita,Toshiaki Murata,J. Tamura,Masatoshi Sugimasa,Akiyoshi Komura,Motoo Futami,Masaya Ichinose,Kazumasa Ide +8 more
TL;DR: This paper presents a combination system of wind energy conversion and hydrogen production, in which a variable speed wind generator is adopted, and an electrolyzer is installed in parallel with it for hydrogen production.
Patent
Fuel cell system and control method
TL;DR: In this paper, a battery voltage Ef of a fuel cell was detected and a current instruction value which transformed an electric power instruction value Pfc of the fuel cell is reduced at falling-down of the battery voltage.
Patent
Power Generation Apparatus Using AC Energization Synchronous Generator And Method Of Controlling The Same
TL;DR: In this article, the rotational frequency of an AC energization synchronous generator is estimated or calculated based on a frequency of a stator side voltage of the switching device, while the switch device is open.
