Development for Measurement of Operating Parameters of Synchronous Generator and Control Systems

On load tests to measure operating parameters of apparatus in typical thermal and hydraulic power stations were performed. The results obtained by static characteristic tests of generator were greatly affected by magnetic saturation. Authors propose a new method to estimate on load synchronous reactances from no load factory tests. For dynamic characteristic test, authors conducted'a new arbitrary-axis load rejection method in addition to d-axis and q-axis load rejection method proposed by F. P. de Mello[1].
