Method and design to modify the limit and protection software on a generator exciter s ncrono to compensate for the turbine-generator capacity

摘要

Invention patent: b "method and apparatus for modifying the software to limit and protection in a driver su00ecncrono generator to compensate for the capacity of the turbine generator" d .A method and apparatus for offset, consistent with changes in the conditions of cooling, protection and limit functions of a generator.The limits of the curve generator capacity, including the region superexcitada, region subexcitada and region limited by the heating current of the stator.Are modified in response to changes in pressure or temperature of the coolant that depends on the type of generator that is being compensated.The feedback signals and points of adjustment being provided for protection functions, and limits laid down,Are intercepted and modified according to the relationship between the values of the nominal capacity of the generator and the performance of the generator in order to changed conditions in the liquid refrigerant.The protection functions, and limits are automatically coordinates. As a result, the overall performance of the generator is improved.
