LOW INERTIA SYNCHRONOUS GENERATOR INSTABILITY
I have an HVDC system. The terminals include an HVDC inverter 1000MW rated, a RES 1000MW rated, another inverter 500MW, a load and a generator using synchronous machine. When i use a machine rating at 1000 MVA, everything works. When i try to reduce the rating to 500MVA maximum, in order to have a case where a country is in its critical case of lower inertia, i get instability when both inverters (1000MW and 500MW) are connected to the system. when i disconnect one of them the system is stable. For the synchronous machine i only changed the Rated power and the transformer voltage to scale down. not the H etc.
Does anyone know how can i fix this?I have an HVDC system.
