| Abstract: | Considering the problem that the offset and jitter of the displacement sensor for the main distribution valve of governor in Xiangjiaba Hydropower Plant caused the governor's adjustment quality to drop,the reasons of the inaccurate measurement are analyzed,and the corresponding technical modifications are put forward.After the modification,the measured value of the sensor is stable and accurate,and there is no offset and jitter,which greatly improves the stability of the governor. |
