摘要： Legacy automatic variable capacitor KVAR compensation systems typically use either electromechanical devices such as relays or contactors of various forms and types to switch the selected capacitors in and out of the electrical system under some form of electronic control. These systems are slow and discontinuous in their ability to closely regulate the exact value of compensatory capacitance needed to compensate the variable and rapidly changing reactive power KVAR in the electrical power transmission and distribution networks. The present invention provides a fast response active KVAR compensator based on a variable transimpedance topology.

摘要： A computer-implementable control algorithm that measures: 1) the reactive power; 2) the power factor; 3) the voltage; and 4) the line frequency. The algorithm calculates the differential compensation capacitance required that is either positive (capacitance to be added), or negative (capacitance to be removed). The new compensation capacitance is calculated from the sum or difference of the differential compensation capacitance and the current compensation capacitance. The algorithm compares the capacitor switching bit pattern for the current compensation capacitance and the capacitor switching bit pattern for the new compensation capacitance, and selects a capacitor switching bit map accordingly. The capacitor switch combination for the new compensation capacitance is switched in incrementally according to the capacitor switching bit map. To reach the selected capacitor switch combination, only one switch is switched at a time to minimize the line transient noise. This part of the algorithm continues to run until the PF is corrected, with the capacitor switches being switched on/off each delayed by a millisecond interval to minimize line transient noise.

摘要： An energy saving alternate current (AC) series voltage regulator comprises an AC high frequency (HF) series voltage buck power regulator, a bypass contactor (K1), a bidirectional AC semiconductor device (S1) connected in parallel with the bypass contactor and a control circuitry. Under the condition of an input AC mains voltage (Vin) drops below a specified and set optimum energy savings voltage or a lower selected voltage point, the control circuitry transitions both the slow bypass contactor and the fast bidirectional AC semiconductor device, then the AC high frequency (HF) series voltage buck power regulator are switched out to save the AC high frequency (HF) series voltage buck power regulator internal power electronics usage. Under this condition, the lower input AC mains voltage is directly delivered to an electrical load by the contactor bypass system, hence achieving more energy savings.
