Abstract
The work describes the application of the methodology of defining the actual PQ diagram on the example of Hydrogenerator-turbine unit No. 3 at Vinodol Hydroelectric Power Plant. Used as a basis for preparing documents and determining the unit’s operating tolerances was a block diagram in Figure 15, contained in [1], which provides a clear survey of the sequence of steps required to create an actual PQ diagram. All intermediate steps are documented and the obtained results are shown in tables and graphics. Each of finally defined limits is imported into the actual PQ diagram of the observed unit.
Considering the complexity of calculating the limit conditions imposed by electromagnetic and thermal occurrences in the end region, in a concrete example from practice the present work describes an entirely new methodology of determining the limit values of the longitudinal magnetic induction component, based on the results of measuring induction and pertaining over-temperature in the generator’s permanent capacitive operation. The proposed method is applicable to any synchronous generator.
