摘要： An apparatus is provided for minimizing the peak power demand on an inverter in a power supply with one or more switched reactive loads comprising an AC semiconductor bypass switch connected in parallel with the inverter and a bypass control device. The bypass control device includes filters for selecting load current signals with specific frequencies of interest from the switched reactive loads; a signal processor for sampling and transforming the selected load current signals into frequency domain to identify frequency components of the selected load current signal; an amplitude detector for detecting peak current amplitudes of the identified frequency components of the selected load current signal; and a bypass driver.

摘要： A method of determining one or more direct voltage reduction (DVR) factors at a point of load (POL) in a power grid voltage environment. An energy processing unit (EPU) is installed at each individual POL; each EPU includes at least one AC-AC series voltage regulator. An EPU-regulated output voltage is increased under specific controlled conditions. One or more independent DVR factors for each individual POL are determined during the increased and decreased EPU-regulated output voltage.

摘要： In the present legacy electrical power generation and distribution system, the power quality delivered to end consumers is being degraded by a number of disruptive technologies and legislative impacts; especially with the rapidly increasing myriad of privately owned and operated domestic and commercial distributed energy generation (DEG) devices connected at any point across a low voltage (LV) distribution network. The present invention bypasses this increasing critical DEG problem by offering a solution comprising an energy processing unit (EPU) that is installed at the edge of the high voltage (HV) transmission grid.

摘要： A device and method are provided for monitoring quality and performance parameters of an electricity distribution component in an electricity distribution network and detecting any deviation of operating parameters from the specified regulatory set and enforced limits. The critical and increasing problem is mitigated for the myriad of private domestic and commercial DEG devices being installed and connected to the distribution networks which were not initially designed for, or even not anticipated with, the recent DEG evolution, and the increasing complex electrical components with changing loads and power factors across the distribution network.

摘要： A high-efficiency system for conducting power factor (PF) and harmonics correction in an electrical network, comprising a controller; a digital PFC capacitor array comprising two or more passive PFC capacitors, providing fine steps increments in the PF correction; and linear PFC capacitor arrays, providing coarse steps increments in the PF correction. The PF correction in coarse steps increments and fine steps increments allow a total or near total PF correction without overcompensation. Optionally, the system further comprises a lower power active power filter (APF) configured to only target and eliminate or minimize harmonics in the electrical network.
