摘要： Converter stations (104) have real and reactive power set points initially determined as part of a main loadflow analysis routinely performed on the AC power system connected to the converter stations (104). Viable real and/or reactive power set points for the converter stations (104) can be identified by calculating real and/or reactive power set point candidates for the converter stations (104) before the main loadflow analysis is performed again on the AC power system. The power set point candidates are calculated based on information determined as part of a previous iteration of the main loadflow analysis on the AC power system. The power set point candidates which violate an operating constraint imposed on the AC power system are identified, and a region of valid power set points is defined for the converter stations (104) that excludes the power set point candidates which violate an operating constraint imposed on the AC power system.

摘要： A turbine-based energy generation system (100) includes an electric generator (102) and auxiliary load (112). A power system for the turbine-based energy generation system includes a main converter (106) and an auxiliary converter (110).

The main converter (106) is also operable to deliver power provided from the power collection system (108) to the auxiliary converter (110) when the main converter (106) is decoupled from the generator (102). The auxiliary converter (110) is operable to deliver power generated by the electric generator (102) to the auxiliary load (112) when the auxiliary converter (110) is coupled to the generator (102). The auxiliary converter (110) is also operable to deliver the power provided by the main converter (106) from the power collection system (108) to the auxiliary load (112) when the auxiliary converter (110) is decoupled from the generator (102).

摘要： A series injection device includes a power splitter coupled to two or more lines of an AC power system. The power splitter includes a coupling transformer for each phase of a single phase or polyphase AC circuit that includes the two or more lines. Each of the coupling transformers couples one of the phases of the two or more lines. The power splitter is configured to inject a first voltage of a first polarity into one or more of the two or more lines and inject a second voltage of a second polarity opposite the first polarity into at least one of the two or more lines via the same coupling transformers used to inject the first voltage. The first and the second voltages are controllable, and may or may not be independently variable.

摘要： A fault in a DC power source, such as a battery string or a string of photovoltaic cells, is identified by detecting a change in an AC component of a residual current of the DC power source. In some embodiments, the DC power source is coupled to at least one DC bus and he methods further include generating an AC voltage on the at least one DC bus. For example, the DC power source may be coupled to a modulated DC bus of an uninterruptible power supply (UPS) system comprising an inverter having an input coupled to the DC bus. The inverter may be configured to generate an AC output voltage and the AC component has a frequency that is a harmonic of a fundamental frequency of the AC output voltage, such as a third harmonic of the fundamental frequency of the AC output voltage.

摘要： A wind turbine is disclosed having a generator and rectifier and structured to provide direct current power that in one form is medium voltage direct current (MVDC). The wind turbine includes a crowbar circuit arranged to protect from a condition such as an overvoltage. The crowbar can be activated based on a voltage measurement or rate of change of voltage. A resistor can be coupled to the crowbar to absorb excess power provided by the generator during the overvoltage condition. Individual wind turbines in a wind farm can each have individual crow bars that can be activated based on local measurement of a voltage condition. In some forms the crowbar can be coupled with a transformer, for example coupled with a tertiary winding of a three winding transformer.
