摘要： A system and method to evaluate characteristics of transient events in an electrical power system to determine the location of a transient source type, the source type of a transient event, and suggested mitigation measures that might reduce or eliminate the effects of the transient. The electrical power system has a plurality of monitoring devices that each may detect the occurrence of a transient event incident upon the power system. A controller is coupled to the monitoring devices. The monitoring devices measure signal parameter values associated with the transient event, and the location of the transient event is automatically determined by evaluating transient characteristics from each of the recording monitoring devices. Other measurements of signal parameters may be made to determine transient characteristics. The transient characteristics may be used to determine the source of the transient event, the type of transient event, mitigation measures, and the effects or predictive effects of mitigation measures.

摘要： A switching mechanism provides sequential switching of first and second circuit breakers to enable switching between a primary power supply and a backup power supply. The switching mechanism comprises a first actuator plate to operate a first circuit breaker connected to a primary power supply, a second actuator plate to operate a second circuit breaker connected to a secondary power supply, and an actuator. The first and second actuator plates are independently movable between on and off positions. The actuator is operatively connected to the first and second actuator plates so that the actuator moves the first actuator plate to an on position and the second actuator plate to an off position when the actuator is moved in a first direction, and moves the first actuator plate to an off position and the second actuator plate to an on position when the actuator is moved in a second direction. An override enables movement of the first and second actuator plates from the on position to the off position when the other actuator plate is in the off position. The switching mechanism can be installed in an existing distribution panel in a home of building.

摘要： A control circuit synchronizes an ac power inverter to the mains voltage of an electrical grid by matching the fundamental phasor components of the inverter’s output voltage to the fundamental phasor components of the mains voltage. Once such matching meets an acceptable voltage error threshold, the control circuit initiates contactor closure, verifies contactor closure, and then initiates a changeover from voltage-mode control used in synchronization operations to a current-mode control of the inverter’s output. The control circuit provides corresponding disconnection control when disconnection from the grid is desired, wherein the regulated power of the inverter is ramped down in controlled fashion until it reaches a lower threshold whereupon contactor opening is initiated. Once contactor opening is verified, regulation control reverts to stand-alone voltage mode control or to shut down, as needed or desired.
摘要翻译：控制电路通过将逆变器的输出电压的基本相量分量与电源电压的基本相量分量相匹配来将交流功率逆变器与电网的电源电压同步。一旦这种匹配满足可接受的电压误差阈值，控制电路启动接触器闭合，验证接触器闭合，然后启动从同步操作中使用的电压模式控制切换到变频器输出的电流模式控制。当期望从电网断开时，控制电路提供对应的断开控制，其中逆变器的调节功率以受控的方式下降，直到其达到较低的阈值，从而开启接触器的开启。一旦验证接触器打开，调节控制就会根据需要或需要恢复到独立的电压模式控制或关闭。

摘要： An automatic method of which days/hours represent good candidates for reducing demand to achieve potential savings and the amount of demand reduction that can be achieved with a tolerable level of disruption to status quo operations. Demand interval data including utility usage rate (UUR) values is received from one or more utility monitoring devices, and are sorted in descending order. A percent difference is calculated for each UUR value relative to the previous one, and a cumulative percent difference accumulates the percent differences from the preceding rows. The average cumulative percent difference is divided by the total number of UUR values in the measured period to produce a ratio. The standard deviation of time is determined, and from those demand data associated with ratios greater than a ratio threshold and standard deviations less than a standard deviation threshold the demand reduction amount and the number of control hours are determined.

摘要： An exemplary power inverter comprises a push-pull inverter circuit that includes a transformer having a primary winding coupled to a DC bus and a secondary winding coupled to an AC bus, main power switches coupling each end of the primary winding to a DC return, and one or more supplemental power switches coupling at least one end of the primary winding to a snubber bus. The supplemental switch at a given end of the primary winding forms a buck-mode converter in combination with the primary winding and the associated free-wheeling diode at that end of the primary winding, and can be controlled by a switching controller to effect energy transfer between the snubber bus and DC bus. The switching controller can be configured to control power flow between the DC, AC, and snubber buses by controlling the common-mode and differential-mode voltages of the primary winding via main/supplemental power switch control.
