Abstract: The present invention is directed to a High Voltage Direct Current HVDC link with Voltage Source Converters VSC (3) and interconnecting two power systems (1). A model-predictive control with a receding horizon policy is employed for controlling the outer loop of a two-loop or two-layer control scheme or setup for the HVDC link. The two-loop control scheme takes advantage of the difference in speed of the dynamics of the various system variables of the HVDC link and the interconnected power systems. Model-based prediction representative of the interconnected power systems' behaviour allows comparing the future effect of different control inputs applied within the control scheme, while taking into account any physical, safety and operating constraints. It is valid for a complete operating range, i.e. it avoids performance degradation when moving away from the nominal operating point of the control scheme for a HVDC link.

Abstract: A method and a system are proposed to start at least two AC motors (SM, IM) which are supplied by a power converter (8) via a common AC bus (7). A synchronous motor (SM), which is one of the at least two AC motors, is started first. Afterwards, the reactive power (Q) of the power converter (8) is determined.

The increased field current (i f ) or field voltage (v f ) is then applied to an excitation circuit of the synchronous motor (SM).

Abstract: The present invention is directed to power systems comprising a High Voltage Direct Current HVDC link with a Voltage Source Converter VSC. The proposed control method is model-based and predictive. It comprises a discrete-time prediction model, used to predict the future behaviour of the system, the expression of the system's control objectives in an objective or cost function, and the solution of an optimization problem consisting of the minimization of the objective function over a future prediction horizon, subject to the predicted system evolution and the system's constraints. The model of the power system, instead of focusing on a specific operating point, captures the dynamics of the system and is valid for the complete operating range. This results in a control system that can deal more effectively with disturbances pushing the system away from its original operating point.
