摘要： A system for preventing objectionable large torque pulsations during the starting and synchronization of a line-start permanent magnet motor compares motor speed with motor synchronous speed and power source phase with the motor back-emf phasor. The motor starting armature is coupled to the power source and the PM armature is disconnected from the power source before motor speed has reached to within a predetermined margin of synchronous speed and before the back-emf phasor has dropped below a predetermined phase difference. After motor speed has approached synchronous speed to within the margin and the phase difference has dropped below the predetermined phase difference, connections are reversed so that the starting armature is disconnected from the power source and the PM armature is coupled to the power source.

摘要： An active damping control device for an active power filter includes a filter circuit having an inductor and a capacitor for suppressing noise in the active power filter; a first current sensor for sensing a three phase capacitor current of the filter capacitor; a second current sensor for detecting a three phase load current; and an active power filter controller for extracting the fundamentals of the capacitor and load currents and calculating a reference current for the active power filter. The active power filter controller can include a phase locked loop device or a notch filter for receiving a grid voltage and providing a corresponding voltage angle; first and second discrete fourier transform devices for using the voltage angle and the capacitor and load currents for extracting the fundamentals of the capacitor and load currents, respectively, and providing respective first and second output currents; and a subtractor for subtracting the first output current from the second output current to obtain the reference current. The active power filter can further include, situated between the first discrete fourier transform device and the subtractor, a multiplier for multiplying the first output current by a predetermined factor and a high pass filter for filtering the first output current. The filter circuit can include a circuit breaker coupling the inductor, the capacitor, and the first current sensor to the load for providing overcurrent protection to the filter circuit.

摘要： A set of command signals is generated for application to the respective lines of a four-wire three phase power distribution system to compensate for harmonic distortion and neutral unbalance. A transform operation is performed upon a first set of signals, which collectively represent the uncompensated load current in each of the main transmission lines of the power distribution system, to generate a second set of signals which collectively represent the active and reactive components of the current in the system. Signal components at the fundamental frequency of the three phase system are removed from the active and reactive components to provide only harmonic active and reactive components. A reverse transform operation is performed upon the harmonic components to provide a set of command signals.

摘要： A method and system for compensating for line imbalances in line commutated converters. The controller includes a phase-locked loop (PLL) synchronizing tool which receives the line to line voltage signals and generates firing angle and frequency signals used for synchronizing the two input signals. The PLL controller, in addition to the firing angle and frequency signals, also generates signals representative of filtered values of amplitudes for each of the line to line voltage signals. A voltage imbalance compensation processor associated with the bridge firing controller receives the filtered amplitude signals and also a signal representative of the firing sector of the bridge. The voltage imbalance compensation processor generates, based upon the sector signal and the received filtered amplitude signals a amplitude signal used by a current regulator which is compensated for line imbalances present in the line voltage.

摘要： A method and system for compensating for voltage notches in phase locked loop (PLL) control devices. A bridge firing controller receives signals representative of two of the line to line voltages received by the bridge. The controller includes a PLL synchronizing tool which receives the line to line voltage signals and generates a synchronizing phase error signal for aligning the phases of the two input signals. The controller, for a predetermined period following bridge firing, determines whether a voltage notch has occurred. If so, the controller substitutes model control signals for actual control signals so as to reduce the effect of the notch on the generated phase error signal used for synchronization. If not, the controller continues to use the actual control signals to generate the phase error signal. Once the predetermined period has expired, the controller utilizes the actual control signals to generate the phase error signal.

摘要： A method and system for determining zero current level occurrences in a reversible power converter without requiring additional component complexity and costs. A digital controller selectively determines the line to line voltage for the most recently fired thyristor pair. The selected line to line voltage is identified as the bridge reconstruction voltage and is compared against the actual bridge output voltage for the conducting bridge. The difference between the two voltage signals is identified as the bridge error voltage and the sign of its magnitude is indicative of a load current zero level occurrence. A zero current level occurrence happens whenever the bridge error voltage drops below zero. This indication is positive and substantially instantaneous and safely enables the reversal of power flow without the risk of line faults due to cross-bridge short circuits.
