摘要： A wind turbine generator control system is provided for controlling output of a plurality of tightly-coupled windfarms 10, 15, 20 connected at a point of common 25 coupling with a power system grid 30. A master reactive control device 75 employs algorithms 295, 380 whose technical effect is to coordinate the real power, reactive power and voltage output of the multiple windfarms. The master reactive control device 75 incorporates a reactive power regulator 100A that can be used to regulate reactive power, power factor or voltage at the point of common coupling 25 and an active power regulator 300 that can be used to regulate real power at the point of common coupling 25, such that each windfarm 10, 15, 20 is not asked to contribute or violate its own operating capability.

摘要： A method for regulating a wind energy installation including a rotor-driven generator, a converter connected to the generator, and a controller that regulates power emitted into an energy transmission system to within a limit value involves determining a maximum current value in a connection path, determining a current reserve value for power emitted into an energy transmission system, and determining a correction value for following a limit value of the emitted power from the maximum current value and the current reserve value. The wind energy installation and the method for its regulation also includes the use of a limitation device configured to set a phase angle between an emitted current and voltage of an electrical system in response to a selection signal in such a way that primarily active power or primarily reactive power is fed into the energy transmission system when the maximum current value is reached.

摘要： A wind powered turbine (3) with low voltage ride-through capability. An inverter (28) is connected to the output of a turbine generator. The generator output is conditioned by the inverter resulting in an output voltage and current at a frequency and phase angle appropriate for transmission to a three-phase utility grid. A frequency and phase angle sensor is connected to the utility grid operative during a fault on the grid. A control system is connected to the sensor and to the inverter. The control system output is a current command signal enabling the inverter to put out a current waveform, which is of the same phase and frequency as detected by the sensor. The control system synthesizes current waveform templates for all three-phases based on a sensed voltage on one phase and transmits currents to all three-phases of the electrical system based on the synthesized current waveforms.

摘要： The invention relates to a static energising system (20), for the field winding (17) of a generator (16), connected to a network by means of a busbar (19), comprising a first means (12, 18, 21), for generation of a DC voltage, said first means (12, 18, 21) connected on the input side to the busbar (19) of the generator (16), the outputs of which are connected to the field winding (17), forming an energising circuit together with the field winding (17) and second means (23), for the output of electrical energy, said second means (23), when required, supplying short-term additional power to the energising circuit. According to the invention, a possibility for short-term increase in energising may be achieved in a simple, functionally-secure and space-saving manner, whereby a flow directionally polarised diode (22) is inserted in the energiser circuit and the second means (23), for supply of power to the energiser circuit, may have a polar connection to the diode (22) in the blocked direction.
