【Abstract】 The SiC nonlinear de-excitation resistors are generally applied in de-excitation devices for large-sized hydropower generating units.It is very important for safely operating large-sized hydropower generating units where the parameters are monitored real-timely during and after accidental de-excitation.The target of developing ESA-1 device is on-line monitoring SiC nonlinear de-excitation resistors.The authors applied the system at a 300MW hydropower generating unit in the Baishan hydropower station,and analyzed the results of field measurement.It shows that the system can meet the requirements of de-excitation device online monitoring for large-sized hydropower generating units.In addition,the system is also suitable for other types of generator units,such as steam turbo-generator units.更多还原
