| Abstract |
The primary task of a HVDC tie is to transmit steady-state active power and thus exchange the power between two networks of different frequencies or which do not operate in synchronism. The steady-state operating points are determined by the thyristor parameters. In general, losses must be kept low for cost reasons. This leads to the familiar pattern of extinction angle control on the inverter side and current control on the rectifier side (or camparable control strategies). The field of activity of a HVDC tie is extending beyond the traditional task of active power transmission. Increasing attention is being given to the network parameters, i.e. active power, reactive power and harmonics. The time range in question for the interaction between the HVDC and the network extends from steady-state and quasi steady-state operation through the transient range to modulation. Very different stabilizing strategies are adopted depending on the particular requirements placed on the HVDC equipment by the network. lndividual stabilization strategies are described with reference to actual HVDC installations. |
