Abstract

Subsynchronous resonance in a network is controlled by monitoring the frequency of an electrical generating system 10 and controlling the resonance by phase-firing thyristors to insert compensating inductance L into the network. The frequency is monitored by measuring half-periods and comparing with a standard frequency, using pulse counting to establish an error signal. The network voltage may also be stabilised by controlling the firing of the thyristors. <IMAGE>
