【Abstract】 This new type of loss-of-excitation protection for generator is a useful invention.It can be applied to both water turbine generator and steam turbine generator. The principle, by which the main relay of this new protection is designed, is the functional relationship between critical value of field voltage to keep static stability and the active power of salient-pole generator.更多还原
