ABSTRACT:
A synchronous condenser is provided on an AC bus line which is connected to an AC power system via a circuit breaker. The AC bus line and a DC bus line are connected via a power converter system. In such a system, if three conditions: the breaker is opened; the synchronous condenser is under operation; and the power converter operates as an inverter, are met, the power converter is driven into a zero power factor operation, i.e., an operation to cancel a capacitive reactive power on the AC bus line including AC filters in order to prevent the synchronous condenser self-excitation.
