SYNCHRONOUS POWER GENERATION SYSTEM AND CONTROL METHOD THEREFOR

To provide a synchronous power generation system in which excitation current supplied to a field, which is a rotor, is directly measured, and reliable overexcitation determination is made.SOLUTION: A synchronous power generation system 10 includes a field 21 which is a rotor, a detection unit 50 which rotates together with the field 21, and detects field current 15 flowing through the field 21, a transmission unit 51 which rotates together with the field 21, and transmits the detected value of the field current 15 in a form of a radio signal 54, and a reception unit which receives the radio signal 54.SELECTED DRAWING: Figure 1 【課題】回転子である界磁に供給される励磁電流を直接測定し、信頼性の高い過励磁判定を実施する同期発電システムを提供する。【解決手段】同期発電システム１０は、回転子である界磁２１と、この界磁２１と共に回転しこの界磁２１に流れる界磁電流１５を検出する検出部５０と、この界磁２１と共に回転し界磁電流１５の検出値を無線信号５４にして送信する送信部５１と、この無線信号５４を受信する受信部と、を備えている。【選択図】 図１
