    摘要: A controller for controlling a reactive series compensator serially inserted at compensator terminals into a power transmission line for controlling the line current. The controller includes a current control loop and a voltage control loop. A current controller outputs a control voltage (ccout) indicating a desired compensator terminal output voltage (uc). A control method selector means generates, in a low output voltage region, a constant reference voltage (uDCref) for the voltage control loop and a variable modulation index mq of a modulation signal m=md cos (&ohgr;t) −mq sin (&ohgr;t). In a high output voltage range, the control method selector outputs a constant modulation index mq and a variable reference voltage (uDCref). The voltage controller outputs the modulation index md of the modulation signal m. Furthermore, the control method selector can include a rate limiter for limiting the change rate of the reference voltage (uDCref). In connection with the control method selection and/or the rate limiter, a decoupling control for making the voltage and current control loops independent from each other can be used. The controllers find particular application in transformerless reactive series compensators for single-phase or three-phase control.

    摘要: A suspended load swaying and vibration preventing apparatus for simultaneously controlling prevention of swaying of a suspended load and suppression of vibration of a structural body is provided in a container crane or the like. A trolley position and a trolley velocity are detected by a trolley position detector and a trolley detector. A swaying shift and a swaying velocity of the suspended load is detected by an image sensor. Furthermore, a shift and a velocity of a structural body is detected by a structural body vibration detector. A controller receives the detection signals from these sections, calculates the optimum trolley velocity based upon a control theory and outputs a trolley velocity command. Then, a trolley drive device is driven in accordance with the trolley velocity command from the controller. The suspended load is delivered to a desired position in a stable manner under the condition that swaying of the suspended load and the vibration of the structural body are suppressed.

    摘要: A reactive power compensator continues operation even when a higher harmonic wave component of an alternating-current power system increases. For an alternating current electric amount indicating one of an alternating voltage and an alternating electric current in an alternating-current power system, the reactive power compensator outputs a changing amount showing a change of the alternating current electric amount. An electric current command limits an electric current command signal based on the changing amount. For example, the changing amount is changed in accordance with the higher harmonic wave component included in the alternating current electric amount.
