摘要： A system for generating a duty cycle control signal for controlling an inverter power train providing an output current waveform to a grid operating with a grid voltage waveform compares a reference current waveform shaped to the grid voltage waveform with the output current waveform to generate an error signal. The error signal is used to generate a corrective control action signal, which is combined with a feed- forward signal representing a nominal duty cycle generated with a feed-forward function. The combination of the feed-forward signal and the corrective control action signal provide the duty cycle control signal.

摘要： A power inverter includes a regulator circuit that controls real and reactive power output by the inverter. The regulator measures real and reactive output power by calculating x-phasor components of the inverter's voltage and current output waveforms. Phasor calculation can be adapted for one or more pairs of single-phase voltages and currents. Determining the fundamental in-phase and quadrature components of output voltage and current reduces computational complexity by permitting the regulator to perform its power control processing largely in a dc signal domain, and enables separate real and reactive power control. The power inverter can include islanding detection logic, which exploits the ability to separately control reactive power. Exemplary islanding detection logic is based on determining whether changing the amount of reactive power output by the inverter induces an output frequency shift.

In some embodiments, a system comprises a first switch-controlled VAR source and a harmonic management block which may each be configured to be coupled to a distribution power network. The first switch-controlled VAR source may comprise a first processor, a voltage compensation component, and a switch.

摘要： The invention relates to a circuit arrangement for operating a load having a reactive characteristic on an A/C power supply. The aim of the invention is to enable reactive power to be compensated in the best possible manner, that is, a circuit arrangement is described that permits an operation close to a cos ? of 1, in order to increase the overall efficiency of the arrangement and to achieve optimum energy saving. In order to control critical operating states, the invention provides a feedback loop that supplies a control current to a further reactive circuit element. Said further circuit element is arranged parallel to the load and to the compensating capacitor, and is acted on by a control current such that said control current counteracts a change in the reactive component of the load. The control current is derived from the load current as a variable proportional to the load current. In this manner a reactor for optimising electromagnetic consumption is produced.
