Dynamic Modelling of Single Generators Connected to HVDC Convertors

The transient behaviour of 'unit-type' schemes consisting of HVDC convertors connected to isolated synchronous generators is analysed using state space theory and a numerical solution suitable for digital computation is described. Examples of computed results are illustrated including normal and disturbed operating conditions. These show that 'unit-type' schemes can operate satisfactorily with or without A. C. harmonic filters.
