Abstract: A power system protection system for preventing a voltage drop resulting from the reactive power characteristic of a power system. A main device for acquiring a system electric quantity of one or a plurality of upper substations detects a voltage drop resulting from the reactive power characteristic of the power system and transmits a detection signal of the voltage drop to a terminal device for acquiring a system electric quantity of one or a plurality of lower substations. Each terminal device sequentially sheds loads starting from those suffering more from the influence of the voltage drop resulting from the reactive power characteristic based on the load voltage and load current of a load bus.

Abstract: A control system (20) for a power converter (22) designed to convert DC power from a source (30) such as a battery, flywheel or fuel cell into AC power. The control system includes an impedance current regulator (106) for providing an impedance current signal to a summing unit (110) where it may be combined with real and reactive current command signals provided from respective sources (62, 64). The resultant current signal provided by the summing unit is provided to a voltage correction unit (112) that uses the resultant current signal in developing a correction voltage signal provided to the power converter. The correction voltage signal contains information used by the power converter in adjusting the real and reactive currents in its output AC power based on the ability of the AC power network to accept changes in current. Multiple power converters having the control system of the present invention may be connected in parallel to a single AC load or multiple AC loads, without the need for a separate control system interconnecting the power converters. The control system may be advantageously incorporated into a distributed generation network and in uninterruptible power systems, whether or not such systems are included in a distributed generation network.

Abstract: An active backup power supply with PFC and power output regulation comprises a power factor correction (PFC) circuit, a backup battery, an inverter and a control circuit. The said PFC circuit outputs current drawn as low THD (total harmonic distortion) and non-pulsating current from municipal power source. The said inverter connects to the PFC circuit and the backup battery at one end and outputs a precisely regulated power source at the other end. The said controller is to control the voltage relation between the PFC circuit and the inverter, so the PFC circuit is controlled in voltage boost mode to draw non-pulsating current from municipal power. With the above-mentioned components, the present invention enables an output power with PFC and voltage regulation to the load device (FIG. 3).
