Definitions

  • the present invention relates to a method for controlling a wind farm
  • Wind farms usually have a large number of wind turbines that
  • the wind farm network In order to feed the electrical power generated by the wind energy plants into an electrical supply network, the wind farm network is usually used
  • a connecting line and a wind farm transformer connected to the electrical supply network.
  • the object of the present invention is therefore to address one of the above-mentioned learners, to improve the general state of the art or to provide an alternative to what is known up to now.
  • improved controllability of wind farms should be provided in the event of a malfunction in the electrical supply network.
  • a method for controlling a wind farm operated by means of a wind farm control unit which comprises a large number of wind power plants having wind power plant controls, which are connected to one another via a common wind farm network which is connected to an electrical supply network of a network operator by means of a wind farm transformer the steps: receiving at least one fault bit at the wind farm control unit, in particular at least one fault bit from the network operator; Deactivating all external setpoint specifications on the wind farm control unit, except those of the network operator, after receipt of the fault bit; Activation of an accident control implemented in the wind farm control unit after successful deactivation of all external setpoint specifications, except those of the network operator.
  • a method for controlling a wind farm is therefore proposed which has a large number of wind energy installations which are connected to one another via a common wind farm network.
  • the wind farm has a central wind farm control unit which is at least set up to receive data from a network operator and also or alternatively to control the individual wind turbines of the wind farm.
  • the wind energy plants themselves preferably also have at least one wind energy plant control unit, which is preferably set up to communicate with the wind farm control unit, that is to say to send data to it and to receive data from it.
  • the wind farm control unit now receives a fault bit, in particular the fault bit of a network operator.
  • a safe line between the wind farm control unit and the network operator can be provided for this purpose.
  • the secure line can be provided, for example, by an underground cable or by a radio link.
  • the secure line can also be a fiber optic line or a VPN tunnel, especially a smart meter gateway.
  • the fault bit itself is preferably to be understood as a separate signal, which in the simplest case consists of only one bit, that is either “0” or “1”, and is intended to trigger a fault control in the wind farm control unit, that is to say a separate operating case or one operating mode: accident control.
  • the fault bit is preferably designed such that a signal is only present in the event of a fault, ie “1”.
  • an accident control or an operating mode accident control implemented in the wind farm control unit is activated, in particular as described below.
  • the accident control itself, at least the following properties are preferably fulfilled: deactivation of all external setpoint specifications, except via the network operator interface; Deactivating all positioning range restrictions, in particular by means of wind farm regulation or by the wind farm control unit; Setting a starting block in the event of temporary lack of voltage or setting the active power to zero after voltage recovery.
  • the wind farm thus has at least one operating mode: normal operation and one operating mode: accident control, in particular as described below.
  • different parameter sets are preferably stored in the wind farm control unit.
  • the wind farm control unit preferably has a setting range limitation and the method further comprises the step: deactivating the setting range limitation after receipt of the fault bit. It is thus proposed in particular that, provided that the wind farm control unit and / or the wind farm has an adjustable adjustment range that can be restricted, it can be deactivated.
  • the wind farm has a setting range for the reactive power, which is limited to a cos (Phi) of 0.95. This is done, for example, when the network connection guidelines only require such a setting range. This avoids additional losses caused by the application of reactive power that is not required. Physically, however, the wind farm has a setting range of 0.5 P nominal, for example.
  • the wind farm control unit preferably has an active power setpoint specification for the plurality of wind energy plants and the method further comprises the step: setting the active power setpoint specification to a value equal to zero.
  • the wind turbines of the wind farm then initially do not feed any power into the wind farm network during the accident control.
  • the method preferably further comprises the step: interrogating a status of the wind energy installations by the wind farm control unit at the wind energy installation controls.
  • the wind farm control unit queries the state of the wind energy plants during the accident control, for example whether the wind energy plants are ready for operation, in particular are ready for the accident control.
  • the wind farm control unit also queries the active power to be expected from the wind energy plants.
  • the control of the wind energy plants has, for example, a power forecasting unit which is set up to predict an expected effective power as a function of a weather forecast.
  • the wind farm control unit is supplied with the expected power values of the wind energy plants, for example reports them to the network operator, or uses them to regulate the wind farm more efficiently in the event of an accident control.
  • the method preferably further comprises the step: transferring warning signals through the wind power plant controls to the wind farm control units and / or transfer of warning signals by the wind farm control unit to the network operator.
  • a wind calm occurs in the area of the wind farm, which means that the wind farm can no longer or not fully implement its accident control system.
  • the controllability of the wind farm as such can also fail. If this has been determined by the wind farm control unit, for example by warning signals from the individual wind energy plants, a corresponding warning message is sent to the network operator.
  • the network operator always knows from the warning messages whether the wind farm can participate in the accident control and / or whether the wind farm is still part of the accident control. The network operator is therefore always able to recognize that a wind farm is not participating and to request or activate a corresponding accident control system from another wind farm.
  • the fault bit is preferably received when the electrical supply network has gone black. It is therefore proposed in particular that the fault bit be used to activate a network reconstruction mode.
  • the network operator transmits the malfunction bit to the wind farm control unit, which thereby activates its malfunction control.
  • a wind farm network reconstruction mode can also be activated, which is part of the accident control.
  • the accident control is thus preferably designed for the network restoration of the electrical supply network.
  • the accident control is preferably activated when the wind farm feeds electrical power into the electrical supply network that is zero. In principle, it is also conceivable to activate the accident control when the wind farm is still feeding electrical power into the electrical supply network.
  • the wind park first freezes its electrical power feed after receiving the fault bit and then starts its power in accordance with the accident control, preferably by means of power ramps.
  • the wind farm control unit preferably has a travel time that is shorter than the travel time of the plurality of wind energy plants.
  • a wind farm comprising a plurality of wind energy plants, a wind farm network connecting the plurality of wind energy plants and a wind farm control unit which is set up to carry out at least one method described above or below.
  • the wind farm control unit is thus in particular set up to operate the wind farm in one operating mode: normal operation and in one operating mode: accident control.
  • the operating mode accident control, for example, another parameter set is provided, the accident parameter set.
  • the accident parameter set is preferred stored in the wind farm control unit and also or alternatively in the wind turbine control units.
  • the fault parameter set preferably includes at least one function from the list below: a) With the electrical supply network temporarily de-energized: start-up of all wind turbines and preparation for feed-in, the active and reactive power setpoint being transferred from the wind farm control unit to the wind turbine control unit passed, remains at zero; b) upon activation of the operating mode: normal operation: setting the active power setpoint of the wind turbine control units by the wind farm control unit to a current feed-in power; c) when activating the operating mode: Incident control: Deactivating all setting range restrictions of the wind farm control unit; d) Active power control with reserve power and P (f) characteristic without dead band; e) predefined active power ramps (control speed) for new setpoints; f) no allowance of setpoints greater than P available 10% P available (q (1qG P nominal), in particular
  • the voltage and frequency are preferably regulated, in particular with a maximum possible dynamic range, e.g. twice pnenn per second or ten times qnenn per second, especially in both positive and negative directions.
  • the wind farm control unit preferably has at least one operator interface, which is set up to receive external setpoint values, and a network operator interface, which is set up to receive the fault bit.
  • the wind farm control unit thus has at least two interfaces for data exchange outside the wind farm, one interface being provided exclusively for the network operator, namely the network operator interface, by means of which the fault bit is preferably received.
  • the wind farm control unit also has at least one wind turbine interface, which is set up to transmit setpoints to the wind turbine.
  • the wind farm control unit preferably also has a wind power plant warning interface that is set up to receive warning signals from wind power plants, and also or alternatively a wind farm warning interface that is set up to send warning signals to the network operator.
  • the warning signals are preferably provided to reflect a status of the wind turbine or the wind farm.
  • the wind farm control unit preferably has at least one interface or a further interface which fulfills at least one of the following functions: activation of an operating mode: accident control; Switch off or ignore all external setpoint specifications except from the network operator; Entry of new setpoint, such as setpoint frequency; Receiving and / or sending warning signals, in particular regarding primary control capacity, reactive power setting range, accessibility to the wind farm, status signals, P-available, Q-available, current primary control capacity or the operating mode: Incident control.
  • the wind farm preferably further comprises an uninterruptible voltage supply, which is set up to supply the wind farm control unit and / or the plurality of wind power plants with electrical power for a predetermined period of time in such a way that the wind farm can carry out a black start, even if the electrical supply network does not Has tension.
  • an uninterruptible voltage supply which is set up to supply the wind farm control unit and / or the plurality of wind power plants with electrical power for a predetermined period of time in such a way that the wind farm can carry out a black start, even if the electrical supply network does not Has tension.
  • the uninterruptible power supply is at least in the form that at least the communication between the wind farm control unit and the network operator can be maintained.
  • the predetermined time period is preferably at least 4, preferably at least 8, hours. It is thus proposed in particular that the uninterruptible power supply is dimensioned such that the wind farm can carry out its accident control for at least 4, preferably at least 8, hours independently, even when there is no wind. In a particularly preferred embodiment, the predetermined period is at least 48 hours.
  • the wind power plants preferably each have a wind power plant control which is set up to be operated with at least one operating parameter set and one fault parameter set and to switch between the operating parameter set and the fault parameter set on a signal from the wind farm control unit.

  • the incident parameter set has the functions described above or below, in particular the same functions that the incident parameter set of the wind farm control unit also has.
  • the wind energy plants are thus designed and set up for at least two different operating modes, one operating mode being provided specifically for accident control.
  • the wind farm control unit is preferably set up to record at least one size of the electrical supply network, which indicates a fault in the electrical supply network, in order to generate the fault bit and to generate the fault bit. It is therefore proposed in particular that the wind farm control unit automatically detects a malfunction and automatically initiates the malfunction control without the network operator having to call the malfunction. It is particularly advantageous here that the automatic detection of the incident by the wind farm is significantly faster than the incident detection by the network operator.
  • a wind power plant of a wind farm described above or below comprising a wind power plant control which is set up to be operated with at least one operating parameter set and a fault parameter set and to switch the wind power plant control to a signal of the wind farm control unit between the operating parameter set and the fault parameter set , in particular to participate in a method described above or below.
