  • Patent number: 11188933
    Abstract: The invention relates to a multi-objective optimization method for power system peak-shaving based on index linkage analysis. The invention comprehensively considers five peak shaving indexes, and introduces a linkage analysis theory in economics to test stationarity and causality of data series of peak-shaving indexes. The purpose is to effectively clarify linkage relationship between indexes. A regression analysis method is used to quantify the mutual influence relationship. A multi-index coupling peak shaving optimization model for generation scheduling is developed and finally solved by using genetic algorithm. The invention can objectively describe comprehensive peak shaving requirements of a provincial power grid, and is helpful for generation dispatcher to reduce subjective assumptions in the decision-making.

  • Patent number: 10425056
    Abstract: An EMI filter network may be used to provide interference filtering for multiple loads (referred to collectively as a dynamic load). In one aspect, the EMI filter network includes electrical switches that establish different configurations or arrangements of passive circuit elements (e.g., inductors and capacitors) where each configuration generates a different filter value. The EMI filter network may be communicatively coupled to a controller which changes the configuration of the EMI filter network using the switches in response to the dynamic load changing operational states. For example, each configuration of the EMI filter network may correspond to one of the operational states of the dynamic load. Thus, as the operational state of the dynamic load changes—e.g., different motors become operational—the controller alters the configuration of the EMI filter network to provide a filter value that corresponds to the current operational state of the dynamic load.

  • Patent number: 10404062
    Abstract: Embodiments are directed to fault-tolerant power-distribution modules (PDM). A PDM is included in a power plant to provide a portion of the power generated by the plant as a direct current (DC) signal for the operation of the plant. A power-distribution system distributes a portion of the power generated by the plant to one or more PDMs, as an alternating current (AC) signal. The PDMs provide electrical power to various plant loads. The plant loads may be related to the safety of the operation of the power plant. At least one of the plant loads is a non-safety related load. A PDM may be a DC power supply. The power plant may include one or more power-generating module (PGM) assemblies. At least one of the PGM assemblies may include a nuclear reactor. Accordingly, the power plant may be a modular nuclear power plant.

  • Patent number: 10340678
    Abstract: A circuit breaker includes main contacts movable between closed and open positions such that a line terminal and a load terminal are, respectively, in electrical communication or electrically isolated. A trip coil is connected to the contacts, causing the contacts to move from the closed position to the open position in response to a trip current, thereby tripping the circuit breaker. A normally closed relay having a relay activating circuit and a switching circuit is provided, with the switching circuit being electrically connected to the trip coil. A monitoring circuit is electrically connected to the relay activating circuit, supplying activating power to the relay activating circuit so long as a determination is made that the breaker is operating within acceptable parameters, and ceasing to supply activating power to the relay activating circuit upon a determination being made that the breaker is not operating within acceptable parameters, thereby tripping the breaker.

  • Patent number: 10310461
    Abstract: Method of controlling distribution of energy within an energy distribution system and energy distribution systems are provided. An energy distribution system includes a central controller and one or more remote distribution control units. A method includes obtaining, with the central controller from the remote distribution control units, operational data indicating an operational condition of the energy distribution system. The method further includes comparing the operational condition to a polling rate threshold that indicates when the operational condition is approaching a condition threshold at which the central controller will operably control operation of the remote distribution control unit. The method further includes adjusting a polling rate at which the operational data is obtained in response to the operational condition crossing the polling rate threshold.

    Abstract: A system is provided for adjusting power provided over a channel to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel. The sub-system can determine an amount by which to increase the power based on a resistance of the channel. The power sourcing equipment or the powered device can adjust the power (or load) in response to a command from the sub-system. The sub-system can include at least one measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel. The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.
