    Abstract: Reactive power (VAR) consumption in a power plant or facility having synchronous machines is adaptively controlled in an automated manner. Electrical parameters of the plant are dynamically monitored during plant operation, and the overall plant power system is brought to an optimum operating point under control of a microprocessor-based power measurement system. The microprocessor-based power measurement system adaptively changes the excitation system of synchronous machines in the plant based on results of monitoring. The excitation systems of the synchronous machines may be adjusted to be constant bus voltage, constant reactive power, or constant power factor, according to optimum system performance requirements. The power measurement system also assists in avoiding problems in voltage regulation during increased load demand conditions, such as when starting large electrical motors or energizing large transformers in the system.

    Abstract: Reconfiguration of stator winding sections of each phase of a multiphase motor is controlled for successive ranges of speed during which the motor can be expected to operate to obtain optimum operating efficiency throughout the entire operating range. All winding sections for a stator element are energized throughout the motor operating speed range but connected, through appropriate switches, in different circuit configurations for respective portions of the speed range. The switches are activated by a controller in response to a sensed motor speed signal. The reconfiguration of stator winding sections may be incorporated within a motor control system that is adaptive to control various motor parameters in response to sensed conditions as well as user input commands.

    Abstract: This invention relates to a variable speed drive with synchronous AC motor. In the disclosed embodiment, a variable speed drive operates in three modes: a first predetermined mode, in which a function (e.g., trapezoidal current waveform) controls operation at low motor speeds; a transitional mode, in which a transition function is applied to anticipate transitions of the first function, thus causing a smoothing of transitions at higher speeds; and a second predetermined (e.g., sinusoidal or smoothly-varying current) waveform at high speeds. This allows for the reduction in required rotor position sensor resolution as compared to conventional synchronous variable speed drives, resulting in cost savings in the sensor device and associated wiring. Additionally, it is quieter and more efficient operation at high speed as compared to conventional trapezoidal-current/DC-brushless motor drives.
