An electric power compensation system for a DC transmission system with an integrated wind turbine generator has been proposed in our preceding paper. The proposed compensation system which consists of asynchronous generator and a duplex reactor is connected to the sending-end circuit of the DC transmission system for the purpose of compensating fluctuations in DC power at the DC transmission system caused by changes in wind velocities and also for the purpose of eliminating harmonic components of the sending-end grid current. A set of detailed steady-state equations of the DC transmission system is derived. Then, theapparent power of the synchronous generator is explored, and the effects of the sending-end grid conditions on the steady-state characteristics of the apparent power are discussed. It is shown that the apparent power decreases when the sending-end grid terminal voltage increases. It is also shown that a large-sized synchronous generator is required when the sending-end grid power factor is leading.
