    摘要： Excitation control circuitry for a synchronous generator is disclosed. The synchronous generator is of a type comprising a main machine (2) and an exciter (6) for exciting the main machine. The excitation control circuitry comprises an automatic voltage regulator (10) for controlling power flow from the main machine to the exciter, and an excitation boost system (14) for selectively supplying power from a second source of electrical power (12) to the exciter (6). This can allow additional excitation to be provided, for example, when the generator is in overload. This arrangement can allow a synchronous generator to be upgraded by adding the excitation boost system to provide enhanced overload performance.

    摘要： A method of controlling connection of an AC power output to a load and power supply grid. The power output is produced by an AC power generating system which includes an AC/AC converter and is independently operable to supply power to the load. The converter is controlled in accordance with a reference generated within the system. To connect the power output to the power supply grid and to supply the load, the reference is replaced by another reference derived from the voltage of the grid, so that the converter is controlled by that other reference, when the power output is connected to the grid and supplies power required by the load. When the power output is disconnected from the grid or loss of the grid voltage occurs, the reference replaces the other reference, and the power generating system operates independently continuing to supply power required by the load without interruption.

    摘要： A power generation system is disclosed for supplying power to an electrical grid. The system comprises a synchronous machine and coupling means for coupling the synchronous machine to a prime mover. Control means are provided to control the system such that the system is selectively operable in two modes. In the first mode, the synchronous machine is coupled to the prime mover and acts as a synchronous generator to supply power to the grid. In the second mode the synchronous machine is decoupled from the prime mover and acts as a synchronous condenser. This can allow parameters of the grid, such as power factor and voltage, to be adjusted.

    摘要： A component for connection between a generator and a prime mover in a power generation system is disclosed. The component may be an adaptor (20, 50, 110) or a bracket (80, 90), and may be arranged to house a fan. The component comprises a rear member (24), a front member (22), and a plurality of cross members (26) which connect the front member to the rear member. The cross members are wedge-shaped and/or lie at an angle with respect to a radial direction. The component may be arranged to surround a fan. The component may facilitate airflow and enhance thermal performance while being efficient from a structural and cost perspective.
