Abstract: A wind-turbine-converter system with inverter controllers for inverters and a distributed error- handling system as well as a method of controlling the same is provided. The inverter controllers are linked by a communication bus with one or more communication rings. The communication bus enables a control word to circulate between the inverter controllers. When an inverter controller detects a fault of an associated inverter, the inverter controller produces a control word indicative of the detected fault. The control word indicative of the detected fault circulates to all other inverter controllers over the communication bus and the inverter controllers perform a given fault-response action.

Abstract: The invention relates to a method for controlling a power generating unit such as a wind turbine which is configured as a virtual synchronous machine. Capacitor voltage signals obtained from voltage measurements of output capacitors are filtered in order to reduce a magnitude of an impedance peak and/or shift the impedance peak where the impedance peak is present in an impedance characteristic of the output of the power generating unit. Filter compensated voltage signals obtained from the output capacitors are combined with a voltage magnitude reference to obtain filtered capacitor voltage signals used for controlling the line side converter and thereby affect the impedance peak in a desired way.

Abstract: A method and apparatus for estimating a characteristic of a wind turbine electrical signal comprises buffering a sequence of sample values of the wind turbine electrical signal and a sequence of sample times corresponding with the sequence of sample values. The time periods represented by the sample times are variable. A sub-sequence of the buffered sample values to integrate is determined, based at least in part on a sum of the time periods. The characteristic is estimated by integrating the sample values in the sub-sequence.

Abstract: A wind turbine converter system (3) with a rectifier (4) and an inverter (5) and a converter controller (11) has at least first and second converter strings (24, 25). The converter system is controlled by a master-converter controller (13) and a slave-converter controller (12). The master-converter controller (13) controls the first converter string (25) and the slave-converter controller (12) controls the second converter string (24). The master-converter controller (13) receives commands from a superordinate wind turbine controller (21), provides the slave-converter controller (12) with string-control commands on the basis of the superordinate control commands, and controls the conversion operation of the first converter string (25) on the basis of the superordinate control command. The slave-converter controller (12) receives the string-control commands from the master-converter controller (13) and controls the conversion operation of the second converter string on the basis of the string-control commands received. The first and the second converter strings (24, 25) can be arranged in a bipolar configuration giving access to a neutral point (62). Fault detection can be performed based on the current through the neutral (62). The system is capable of fault ride-through. Also, in case of failure of the master-converter controller (13), a redundant unit takes its place.
