Abstract: A dynamic mechanically-switched damping (DMSD) system is described which utilizes one or more mechanical switches and appropriate controls to switch series or shunt reactive impedances (14) in order to provide power oscillation damping in power systems. The DMSD system provides a controller (16) which can be configured based on the number of mechanical switches in the DMSD system, the type of reactive impedances interfaced to the power system by each switch and the magnitude of each of the reactive impedance. The DMSD system monitors parameters of the power system (17, 18) and the controller generates a modulation signal based on the monitored parameters. The modulation signal is processed to identify a reactive impedance of the available DMSD system reactive impedances required to damp power oscillations. Appropriate switches (32) are selected for supplying the required reactive impedance. A switching control signal is generated and output to each of the selected switches to synchronously open or close the switch at a predetermined instant.

Abstract: A modular closing resistor assembly (20) can be added in line with the interrupter assemblies (16) of an extra high voltage circuit breaker and has a relatively short length. The resistor element consists of two stacks (70, 71) of disks which are disposed side by side and are electrically connected such that the alternate disks (72, 73, 74) of each stack are connected in series with one another. The operating mechanism of the unit includes a linearly moving roller (120) which engages a crank arm (110) which is in turn pivotally connected to operate the movable closing resistor contact (52) with a motion and with a variable mechanical advantage adapted to cause the resistor contacts (52) to close a high speed just after the interrupter contacts close and to open after the interrupter contacts open.

Abstract: Magnetic core structure of the stacked type having outer legs (11, 12), at least one inner leg (13), and top (14, 15) and bottom yokes (16, 17) formed of a plurality of stacked groups of layers of metallic laminations. The yoke and leg laminations have their ends cut diagonally to provide a closed magnetic circuit having diagonal joints between adjoining ends of the yoke and leg laminations. The length dimensions of the inner leg laminations are uniform from layer to layer within each group, while the junction of the diagonally cut ends of the inner leg laminations are offset from the centerline thereof from layer to layer in a step pattern that progresses an equal number of steps on each side of the centerline of each group of layers of inner leg laminations to be step dependent. The configuration of the outer leg laminations and the top and bottom yoke laminations are uniform from layer to layer within each group to be step independent. A method of stacking the laminations in groups is disclosed and there is also disclosed a method of making the center or inner laminations of the magnetic core structure in two parts where the width of the laminations is greater than the commercially available lamination material.

Abstract: An intelligent circuit breaker or switching device system comprises three separate microprocessor-based units, including a condition monitoring unit (CMU) (40), a breaker control unit (BCU) (50), and a synchronous control unit (SCU) (60). The CMU (40) provides detailed diagnostic information by monitoring key quantities associated with circuit breaker or switching device reliability. On-line analysis performed by the CMU provides information facilitating the performance of maintenance as needed and the identification of impending failures. The BCU (50) is a programmable system having self-diagnostic and remote communications. The BCU replaces the conventional electromechanical control circuits typically employed to control a circuit breaker or switching device. The SCU (60) provides synchronous switching control for both closing and opening the circuit interrupters. The control processes carried out by the SCU reduce system switching transients and interrupter wear. The intelligent circuit breaker or switching device system improves system operation and equipment maintenance.
