| Abstract |
Voltage Source Converters for high-power applications like HVDC and SVC will encourage the use of low commutation frequency which restricts the attainable control performance. In spite of the low switching frequency the control system must be fast-acting In order to handle start-up and different fault conditions. A control strategy is required that brings the converter into stationary state as fast as possible. The paper describes a control method for a voltage source converter. The proposed control method is based on measured converter flux (time integral of converter voltage) and dc voltage, here exemplified in a six pulse unit. The time to next commutation is calculated in real-time so that the converter flux is guided in minimum time from an arbitrary point in the flux plane towards the stationary orbit. |
