摘要： A PoDL system includes a PSE connected via a wire pair to a PD, where differential data and DC power are transmitted over the same wire pair. Typically, low voltage/current detection and classification routines are required upon every powering up of the system to allow the PD to convey its PoDL requirements to the PSE. Various techniques are described that simplify or obviate such start-up routines or enable increased flexibility for the PoDL system. Such techniques include: ways to specify a particular PD operating voltage; ways to disable the PD's UVLO circuit during such routines; using opposite polarity voltages for the two routines; using voltage limiters or surge protectors to convey the PoDL information; detecting loop resistance; using a PSE memory to store previous results of the routines; and powering the PD communication circuit using the wire pair while the PD load is powered by an alternate power source.

摘要： The present invention relates to an electric power control system and method therefor, and comprises a control unit 10 and a transformer 20 connected thereto. The control unit 10 detects varying input voltage in real-time, controls switching of triac devices equipped in the transformer, and applies control signal which switches triac device among a plurality of triac devices for target voltage output to the transformer 20. The transformer 20 outputs target voltage by switching tabs of triac devices according to control signal, supplies power by switching tabs of triac devices corresponding to target voltage included in control signal, and preventing EMF induced from primary coil to secondary coil by grounding the tabs of unused triac devices with N-phase for adjustment to the target voltage.

摘要： Techniques to determine settings for an electrical distribution network are described. Some embodiments are particularly directed to techniques to determine settings for an electrical distribution network using power flow heuristics. In one embodiment, for example, an apparatus may comprise a model reception component, a forecast component, and an optimization component. The model reception component may be operative to receive a model of an electrical distribution network having multiple capacitor banks and multiple voltage regulators, each of the multiple capacitor banks represented in the model by a model capacitor bank, each of the multiple voltage regulators represented in the model by a model voltage regulator, the electrical distribution network having a radial layout in which power flows from a source to multiple nodes in which each node is associated with one voltage regulator. The forecast reception component may be operative to receive a forecast for demand on the electrical distribution network. The optimization component may be operative to receive the model capacitor banks and model voltage regulators and determine one or more settings for the multiple capacitor banks and multiple voltage regulators that allow for providing power within predetermined limits while reducing power loss as compared to a power loss of the existing settings or reducing power usage as compared to a power usage of the existing settings, the one or more settings for the multiple voltage regulators determined according to a heuristic in which potential settings are iteratively determined for each of the model voltage regulators based on a least squares model of load flow analysis. Other embodiments are described and claimed.

摘要： A method for network regulation on threshold value overshoots in a low voltage or medium voltage network, wherein control commands are transmitted from a central regulator of the low or medium voltage network to controllable components of the low voltage or medium voltage network, where information is continuously transmitted from each of the controllable components to the central regulator regarding their emergency reserves for reducing threshold value overshoots, upon a threshold value overshoot, the central regulator calculates the necessary correction and transmits a suitable action instruction to at least one controllable component, with each action instruction, a probability factor is also transmitted which is incrementally raised if, given an insufficient reaction of the controllable components, the threshold value overshoot is not prevented and thus an action instruction must be transmitted anew, and the central regulator informs the network operator if the emergency reserves of the controllable components are insufficient.

摘要： A Power Over Ethernet (PoE) system, or other power over data lines system, includes Power Sourcing Equipment (PSE) providing combined data and voltage over wires to a Powered Device (PD). Since cable length and PD load currents may not be known, there is a variable voltage drop along the cable between the PSE and PD. Prior to the PD being fully powered up, a test is performed by the PSE to determine the actual resistance or voltage drop of the cable, and the results are stored in a memory accessed by the PSE upon powering up. The PSE uses the stored information to adjust its voltage source to provide a target voltage at the PD input during full power operation. This may obviate the need for a voltage regulator at the PD. The test may only be conducted when the PSE is initially powered up or may be conducted periodically.

摘要： A load controller is connected with a residential electric load to regulate electric power drawn by the load from a residential a.c. electric power distribution system via power input terminals of the load. A voltmeter is connected to measure voltage at the power input terminals, and an ammeter is connected to measure electric current at the power input terminals. A microprocessor or microcontroller is programmed to compute a source impedance of the power distribution system as seen from the power input terminals using measured voltage and electric current at the power input terminals. The source impedance may be computed by determining an equivalent source voltage as equal to measured voltage at the power input terminals when the electric current at the power input terminals is zero, and computing the source impedance from measured non-zero electric current at the power input terminals in combination with at least the equivalent source voltage.
