摘要：The invention relates to a method suitable for a system comprising a frequency
converter and a generator which are connected to an electrical grid, said methodcomprising steps of obtaining the subsynchronous components of the network voltageand determining damping current instructions (40', 41') according to said
subsynchronous components in order to compensate ther subsynchronous resonancesof the network. The damping current instructions (40', 41') are determined by means ofregulating means (45') that receive the subsynchronous components of the networkvoltage and send back the damping current instructions (40', 41') as outputs. Saidregulating means (45') comprise a regulator with a variable damping gain (46a') that isadjusted according to the subsynchronous frequency of the network, so as to be able toadapt the required compensation level to the frequency converter in order to damp thesubsynchronous resonance of the network.
