摘要： A variable speed wind turbine is configured to provide additional electrical power to counteract non-periodic disturbances in an electrical grid. A controller monitors events indicating a need to increase the electrical output power from the wind turbine to the electrical grid. The controller is configured to control the wind turbine as follows: after an indicating event has been detected, the wind turbine enters an overproduction period in which the electrical output power is increased, wherein the additional electrical output power is taken from kinetic energy stored in the rotor and without changing the operation of the wind turbine to a more efficient working point. When the rotational speed of the rotor reaches a minimum value, the wind turbine enters a recovery period to re-accelerate the rotor to the nominal rotational speed while further contributing to the stability of the electrical grid by outputting at least a predetermined minimum electrical power.

摘要： A voltage regulator with an adaptive field discharge control system may use the rate of change of the POR voltage, the rate of change of the output current and rate of change of the field current, or any combination of these, as an input. The adaptive field discharge control system may process the inputs, identify an operating condition, such as unbalanced load, overcurrent and overload, and compare reference setpoints against that condition. Conventional field control circuits may be triggered by a fixed POR voltage setpoint for all operating conditions. In addition, conventional field control circuits may trigger field discharge to turn on and off continuously during systems oscillations. To avoid these issues, the adaptive field control circuit of the present invention may include a variable POR voltage setpoint, based upon one or more of the rate of change in the POR voltage, the DC bus voltage, or the percentage of unbalanced load. This invention can be extended for any More Electric Vehicle applications.

摘要： A fault protection system provides fault protection to a permanent magnet (PM) generator. The fault protection system includes one or more overload and short-circuit protection circuits, an unbalanced protection circuit and a thermal protection circuit. The overload and short-circuit protection circuit detects both overload and short-circuit conditions by monitoring current and voltage generated at a single phase by the PM generator. The unbalanced protection circuit monitors and compares current and voltage generated associated with at least two individual phases to determine unbalanced conditions between the phases. The thermal protection circuit detects a thermal overload condition by monitoring the temperature of the PM generator. If the overload and short circuit protection circuit, the unbalanced protection circuit, or the thermal protection circuit detects a fault signal, a control circuit causes a control device to reduce or prevent mechanical power from being supplied to the PM generator, preventing the PM generator from generating power and protecting it from damage.

摘要： A wind powered turbine with low voltage ride-through capability. An inverter is connected to the output of a turbine generator. The generator output is conditioned by the inverter resulting in an output voltage and current at a frequency and phase angle appropriate for transmission to a three-phase utility grid. A frequency and phase angle sensor is connected to the utility grid operative during a fault on the grid. A control system is connected to the sensor and to the inverter. The control system output is a current command signal enabling the inverter to put out a current waveform, which is of the same phase and frequency as detected by the sensor. The control system synthesizes current waveform templates for all three-phases based on a sensed voltage on one phase and transmits currents to all three-phases of the electrical system based on the synthesized current waveforms.
