  • Patent number: 9680301
    Abstract: A photovoltaic power plant with master-slave control architecture. The photovoltaic power plant includes slave plant controllers, with each slave plant controller controlling operation of photovoltaic inverters that convert direct current generated by solar cells to alternating current suitable for delivery to a utility power grid at a point of interconnection (POI). A master plant controller controls and coordinates the operation of the slave plant controllers. The master plant controller generates a global inverter real or reactive power setpoint, which is provided to each slave plant controller. In each slave plant controller, the global set point is processed to generate individual inverter real or reactive power setpoints that are provided to corresponding photovoltaic inverters controlled by that slave plant controller. A photovoltaic inverter generates an output based on received individual inverter setpoint to achieve a desired real power, voltage or power factor.

  • Patent number: 9595846
    Abstract: Aspects of the present disclosure involve systems, methods, and the like, for an automatic transfer switch (ATS) of a power system. The ATS allows for switching between two or more power systems while preventing back-feeding of the power systems. To provide the safety features of the ATS, a safety circuit and control board may be implemented with the magnetic latching relays to control the actions of the latching relays and provide the switching function of the ATS. In one particular embodiment, the safety board comprises one or more electromechanical relays positioned between the controlling electronics of the control board and the magnetic latching relays. The safety board design contains measures to ensure it still functions if one of the disconnect switches is not connected, if one of the connections to a first load phase, a second load phase or neutral is lost and if the main control board is not connected.

  • Patent number: 9584187
    Abstract: Systems and methods according to aspects of the subject technology provide non-interruptive filtering of transmission line communications. The non-interruptive filtering may physically isolate, in the frequency domain, independent networks that share a common transmission media, such as mains wires that are used to deliver both alternating current (AC) power and power line communication signals. The isolation provided by the non-interruptive filtering prevents the transmissions from the independent networks from interfering with each other. In one or more implementations, the non-interruptive filtering may be provided by one or more filters that include cores, such as ferrite cores, around which two mains wires, e.g. a mains live wire and a mains neutral wire, can be wound in opposite directions, respectively. Currents traveling on the mains wires through the filter in opposite phases cancel each other out, thereby blocking symmetric power line transmissions, while allowing AC power to pass through.

  • Patent number: 9531288
    Abstract: A UPS includes an input that receives first power from a utility source to power a load and receives second power from the utility source. The load is separate from the UPS. An inverter receives when in a first mode, the first and second power and when in a second mode, the second power and not the first power. The second power is used to power the inverter. A bypass circuit is connected to the input and bypasses the inverter to supply the first power to an output of the UPS when operating in the second mode. A control module detects a voltage at the output of the UPS, integrates the voltage to generate a first sum, and subsequent to completing a transition between the first and second modes, adjusts an output voltage of the inverter based on the first sum to balance the voltage of the UPS.
