摘要:
Intelligent safety disconnect switching methods and arrangements for PhotoVoltaic (PV) panels are disclosed. A determination is made as to whether a reconnect condition, for reconnecting a PV panel to a power system from which the PV panel is disconnected, is satisfied. The PV panel is automatically reconnected to the power system responsive to determining that the reconnect condition is satisfied. A determination is then made as to whether a power system operating condition is satisfied on reconnection of the PV panel, and the PV panel is automatically disconnected from the power system responsive to determining that the power system operating condition is not satisfied on reconnection of the PV panel.
摘要:
A PhotoVoltaic (PV) panel switching arrangement includes a first switch and a second switch, which in some embodiments are in a DC converter. The first switch is to be coupled between a power system and a first end of a circuit path of the PV panel, and the second switch is to be coupled between (i) a point between the first switch and the power system and (ii) a point between a second end of the circuit path and the power system. The switches are controlled for DC conversion of PV panel output where the circuit path of the PV panel is not to be bypassed, and to disconnect the first end of the circuit path from the power system and to close a bypass circuit path that bypasses the circuit path on a determination that the circuit path of the PV panel is to be bypassed.

A gateway controller allows a plurality of individual power generation units coupled to an electrical distribution grid to be controlled in a coordinated fashion. The gateway controller allows control of the plurality of individual power generation units as a single power generation unit. The gateway controller may determine required control parameters of the power generation units that will provide a desired combined behavior, such as combined alternating current injected into the grid, and issues commands to the power generation units based on the determined control parameters.

Power generating component connectivity resistance monitoring techniques are disclosed. In an array of power generating components that are connected in parallel to a power bus, a power generating component measures an output current that it supplies to the power bus. Respective first and second power generating components measure a first voltage at an output of the first power generating component and a second voltage at an output of the second power generating component. A resistance in the array between first and second connection points in the array through which the output current flows is determined based on the measurements of the output current, the first voltage, and the second voltage.

A bidirectional resonant forward boost power converter (100). E.g. A primary winding of a transformer (102) is coupled in series with a first switch (104) to a first terminal pair (106, 108), the other end of and a second terminal pair (110, 112) and further in parallel to a storage inductance (L STOR 116). The secondary winding of the transformer (102) is coupled to a resonant capacitance (116) and a resonat inductance (L S,RES 118). A second switch (122) is connected in parallel thereto and a third switch (120) in series to a second terminal pair (110, 112). Storage capcitances (124, C126) are coupled to the respective terminal pairs (106, 108; 110,112).
