摘要： A voltage regulator is taught for maintaining the terminal voltage of a three phase transmission line at a fixed reference value. The voltage regulator system utilizes the reactance of the transmission line in conjunction with reactive current from a VAR generator to compensate for the voltage effect of line current as it flows through the line reactance. The VAR generator is of the parallel capacitor-inductor type where the inductor is controlled by a thyristor switch. The conduction of the thyristor is controlled by utilizing a control system which generates an error signal based on the half period average of line voltage. The error signal is converted to a signal which is proportional to flux linkages by an integrator and then compared with the integral of the voltage signal for determining the conduction angle of the thyristor switches.

摘要： A voltage regulator is taught for maintaning the terminal voltage of a three phase transmission line at a fixed reference value. The voltage regulator system utilizes the inductive reactance of the transmission line in conjunction with reactive current from a VAR generator to compensate for the voltage effect of line current as it flows through the inductive reactance. The VAR generator is of the parallel capacitor-inductor type where the inductor is controlled by a thyristor switch. The firing range for the thyristor switch is determined by a fast acting static control system which utilizes line-to-line voltage and line-to-ground voltage as an input. A signal related to the latter voltages is processed and compared against a reference. The integrated difference thereof is utilized to determine the firing angle for the thyristor switch.

摘要： A control circuit for a static VAR generator measures load power during consecutive half cycles of the source voltage. This information, together with load voltage and load current information is used to determine the firing angles of the VAR generator thyristors for providing compensating current for keeping the source current in phase with the source voltage and for balancing the source currents in a three-phase electrical system. The total computation time for determining the firing angles extends into the half cycle in which correction is to be applied beyond a fixed minimum firing angle.

摘要： A current fed unrestricted frequency converter (UFC) for supplying power with balanced voltages to a three-phase unbalanced load generates two sets of existence functions for controlling the switching matrices of the UFC to generate positive and negative sequence current components in the load. Existence function generators generating the positive and negative sequence existence functions are phase locked, respectively, to a positive sequence reference signal generated by a clock and a negative sequence reference signal derived by circuits which monitor the negative sequence voltage in the load. Select circuits alternately gate the positive and negative sequence existence functions to the UFC switching matrices in proportion to the detected magnitude of the negative sequence voltage in a sense to drive the negative sequence voltage in the load to zero. A neutral forming transformer eliminates any zero sequence voltage in the load so that all that remains is the positive sequence components of voltage which by definition are balanced.

摘要： Apparatus and process for the selective cancellation of harmonic frequencies of current produced in a multiphase dynamic stabilizer. A plurality of multiphase dynamic stabilizers providing electrical stabilization are interconnected to a multiphase AC electrical network via a coupling transformer. The leakage reactances and turns ratios of the windings of the transformer are such that the phases of selected harmonic frequencies of current produced in each of the stabilizer means are rotated with respect to those of the other stabilizer means with the selected harmonic frequencies being substantially cancelled in each of the stabilizer means. The harmonics are not the cause of subsynchronous resonance. The cancelled harmonic frequencies are dependent upon the number of dynamic stabilizers used. Where a dual stabilizer system is utilized, the coupling transformer is forked wye transformer having the primary windings connected in delta with the principal secondary windings connected in wye and each principal secondary winding having two auxiliary secondary windings connected thereto. By forming the auxiliary secondary windings such that the ratio of the number of turns therein with respect to the principal secondary winding is about the ##EQU1## and the leakage reactance of the principal secondary winding being equal to about twice the common leakage reactance of the auxiliary secondary windings, the phases of the harmonic currents produced in each stabilizer rotates by approximately 30 electrical degrees with respect to one another leading to the substantial cancellation of harmonic currents of each stabilizer characterized by the series 5, 7, 17, 19 . . . n, p where n=5+z; p=7+z; and z=multiples of 12. Addition of shunt capacitors across each of the primary windings creates a static VAR generator having the same harmonic current cancellation attribute.

摘要： This concerns a compensator for electrical lines fed by a turbine-generator. The mechanical properties of the turbine-generator are such that modulation of the terminal voltage is possible due to subsynchronous mechanical torsional oscillations. If the carrier frequency or synchronous frequency of the generator minus the torsional oscillation frequency is equal to the resonant frequency of the electrical line driven thereby, a relatively large side band current may flow in the electrical line at the resonant frequency. The effect of this current may feedback through the air gap of the generator to increase the torsional oscillation. A boot strapping effect between the electrical properties of the line and the torsional oscillation may thus result which could ultimately end in shaft breakage. The present apparatus utilizes the torsional oscillation signal to modulate compensating inductance connected in parallel between the lines of the electrical system to thus generate a small current at the appropriate electrical resonance frequency. This current leads to the production of a compensating line current at that frequency which in turn opposes the previously described undesirable effect.

摘要： Vibration of a system such as a motor and pump on a platform or a transformer is minimized by applying a compensating force to the system. The optimum compensating force is determined by measuring the initial vibration and using that measurement in one of three algorithms to determine an adjustment to be made to the compensating force applied to the system at the time the initial vibration was measured. The adjusted compensating force is applied to the system which changes the vibration. That vibration is measured and applied to the selected algorithm to determine a second adjustment to the compensating force. The process is repeated until a compensating force is found which produces zero vibration, minimum vibration or a desired vibration. A plurality of sensors for measuring vibration and a plurality of actuators for applying a compensating force are preferably used.

摘要： A bidirectional variable reluctance linear actuator and force control system by which one or more bidirectional linear actuators can be operated to produce a linear relationship between the net force on the armature structure and an applied flux linkage variation signal, as well as an actuator system by which the transmission of vibration through a structure can be blocked by applying forces and/or moments to the structure so as to cancel out its vibratory velocity. An adaptive control system, which is synchronized to machine speed, is able to determine the proper forces that will cancel the vibration of the structure and automatically null out each harmonic of the structure vibration, and cancels the vibration in up to six degrees of freedom of structural motion. The system can provide active attenuation system with a variety of noise sources and transmission paths, i.e., radial (lateral), axial, and torsional, including those associated with propeller shafts, turbine generator sets, pumps, compressors, and other machinery.
