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.

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: A method, converter arrangement, and controller are disclosed for connecting an output of a converter with an electrical grid to control inrush currents into a grid filter assembly connected with the output of the converter, the electrical grid carrying an alternating current (AC) signal having one or more phases. The method includes determining a voltage of the AC signal and operating, after pre-charging a direct current (DC) link of the converter to a predetermined voltage, the converter using open-loop voltage control to produce an AC output signal that substantially matches the AC signal of the electrical grid. The open-loop voltage control is based on the determined voltage of the AC signal. The method further includes closing, after a predetermined amount of time of operating the converter using the open-loop voltage control, a switching device to thereby connect the output of the converter with the electrical grid.

Abstract: A wind turbine generator 1 supplies three-phase a.c. current of variable voltage and variable frequency to two pairs of rectifiers 4a, 4b and 4c, 4d which generate respective d.c. outputs connected to positive, negative and neutral d.c. conductors 6, 7, 8. The outputs from each pair of rectifiers are connected together, and the outputs from the two pairs are connected in series to create a high-voltage d.c. output. Inverters 10a, 10b, 10c, 10d then convert the d.c. power to a.c. at a fixed frequency and voltage suitable for connection to the mains grid. To reduce the effect of common-mode noise, a capacitor is connected between the 1 neutral conductor7 and earth, and a respective filter circuit 30 is connected between each of the a.c. outputs of the inverters 10a, 10b, 10c, 10d and earth. To reduce the effect of voltage surges during lightning, a surge protection device is also connected between the neutral d.c. conductor 7 and earth. Any imbalance in the current in the positive and negative conductors 6, 8 is compensated by detecting the presence of current flowing in the neutral conductor 7. Power supplied to auxiliary circuits from the output of one of the inverters, e.g. 10a, of the wind turbine is measured, and any resulting imbalance between the current in the positive and negative conductors is compensated. In the event of an earth-leakage fault in the conductors connecting the a.c. outputs of the inverters to the grid, when isolated, isolation detection relays 25 are provided.

Abstract: A method for controlling a wind turbine system including an electrical generator, a power converter system, a DC-link, and at least a grid-side breaker arrangement controllable between open and closed states, wherein the method comprises monitoring for the presence of a shutdown event and, in response to identifying the presence of a shutdown event, controlling the wind turbine into a production-ready state, comprising: i) controlling the grid-side breaker arrangement in the closed state; ii) disabling one or more drive signals to the power converter system; and iii) controlling the DC-link of the power converter system in a charged state. Advantageously, this approach reduces the frequency of use of the grid-side breaker arrangement which extends serviceable life considerably, and also allows the wind turbine system to be transitioned rapidly between an operating state and a production-ready state.

Abstract: In a full-scale converter system both the grid-side inverter unit and the generator-side inverter unit have a series connection of parallel inverters and form a generator-side and grid-side voltage-center-point at a voltage level between those of the inverters connected in series. The voltage-center-points are electrically connected by a center-line conductor that has a cross- section between 30% and 70% of that of a positive or negative potential conductor. The converter system continues conversion operation in the event of a fault in an inverter of a first converter-string, with non-faulty inverters of the converter system, as the center-line conductor is dimensioned by said cross-section to carry a compensation current resulting from an unbalanced active power-output.
