The CONCYCLE® frequency converter drives a double fed asynchronous machine in a wind turbine.
The frequency converter is a voltage converter in IGBT technology.
The frequency converter consists of
• Line side converter
• DC-link
• Machine side converter
A liquid cooling dissipates the heat losses of the IGBT power stacks. The coolant from the liquid cooling is a combination of water and antifreeze additive.
The incremental encoder (component of the generator) records rotation speed and rotor position.
The decentralised control unit controls the IGBT power stacks.

20 / 72 9943-1707 - MANUAL - TD OPERATING INSTRUCTIONS - MP1 – ENGLISH
3.2.1 Decentralised and central control unit
Each power cabinet includes an individual decentralised control unit. The decentralised control units are connected to the central control unit.
3.2.2 DC-link
The DC-link couples the line side converter with the machine side converter.
DC-link voltage is generated after precharge by the decentralised control unit and after diode precharge by a boost converter (line choke). The line side converter pulses energy into the DC-link with the help of the line choke.
Due to undesired dynamic changes of the mains voltage, the voltage in the DC-link may increase.
The DC-link limiter protects the DC-link from critical voltage increases. The DC-link resistor of the DC-link limiter converts excessive electrical energy into heat when defined limit values are exceeded.
The energy meter and a temperature monitoring protect the DC-link limiter from overload.

3.3.3 Excitation
Fig. 3-11 Wind turbine in excitation (schematic)
The line side converter (1) regulates the DC-link voltage to the nominal value. If the nominal value of the DC-link voltage is reached and is within the operating range, the machine side converter (2) is enabled and excites the rotor of the generator (3).
The machine side converter (2) generates rated voltage and rated frequency.
3.3.4 Standby
The following applies for standby
• The excitation of the rotor is completed.
• The machine side converter regulates the generator voltage in the operating range to the nominal value, independently of the rotor speed.
• As soon as the signal “load requirement” is active, the control synchronises the generator voltage with the mains voltage.
3.3.5 Mains-parallel
As soon as generator voltage and mains voltage are synchronized, the stator contactor is closed and connects the generator with the mains. The wind turbine is in mains-parallel (parallel operation).
The line side converter regulates the DC-link voltage.
Operating ranges (→ Chap. 3.4):
• Subsynchronous operation: Power is taken from the mains.
• Supersynchronous operation: Power is fed into the mains.
The machine side converter regulates the grid capacity according to the specification of the wind turbine control.
3 Product and functional description
9943-1707 - MANUAL - TD OPERATING INSTRUCTIONS - MP1 – ENGLISH 25 / 72

3.5.1 Control sequence
Fig. 3-15 Control sequence of the heating control
3 Product and functional description
28 / 72 9943-1707 - MANUAL - TD OPERATING INSTRUCTIONS - MP1 – ENGLISH
Initialisation
The heating control is initialized at system start:
• The central control unit calculates the subsequent heating time (→ Chap. 3.5.2).
• The commissioning counter is scanned.
• The heating control is switched over to the central control unit.
• As soon as the relay for the heating operation is switched on, the warning “W12: Heating operation active” appears.
N O T I C E As long as the heating operation is active (warning message W12), the system cannot switch into the operating status “heating”.
• Heating control switches into the operating status “preheating”.
Preheating
Preheating includes cooling liquid heating.
• The following applies for the operating status “preheating”:
o The dew points of the heat sink and the mains cabinet and the temperatures of the cooling liquid and the mains cabinet are checked.
o The relay “ready for operation” is switched off, the wind turbine is not started by an excitation release.
o The relay for the heating operation remains switched on, the warning “W12: Heating operation active” stays.
• Changeover into the next operating status
The heating control switches from the operating status “preheating” into the next operating status when the following conditions are met:
o Cooling liquid temperature > 25 C
o Cabinet temperature > 5 C
o The dew point of the heat sink matches the required value
o The dew point of the cabinet matches the required value
• What is the next operating status?
o Subsequent heating switched on: Change to the operating status “subsequent heating” (→ Chap. Subsequent heating)
o Subsequent heating switched off: Change to the operating status “heating” (→ Chap. Heating)
3 Product and functional description
9943-1707 - MANUAL - TD OPERATING INSTRUCTIONS - MP1 – ENGLISH 29 / 72
• Cooling liquid heating
If one or more conditions are not fulfilled, the heating control influences the measured variables by enabling and disabling the cooling liquid heating.
The heating control switches the cooling liquid heating on if
o the cooling liquid temperature is below the parametrised minimum temperature
o the dew point of the heat sink does not match the required value (cooling liquid too cold)
The heating control switches the cooling liquid heating off if
o the cooling liquid temperature is above the parametrised minimum temperature
o the dew point of the heat sink matches the required value
The heating control switches the cooling liquid heating on if
o the cabinet temperature is below the parametrised minimum temperature
o the dew point of the cabinet does not match the required value (cabinet too cold)
• The heating control switches the cooling liquid heating off if
o the cabinet temperature is above the parametrised minimum temperature
o the dew point of the cabinet matches the required value
Premature cancelling of the preheating in the case of a fault (e.g. heating malfunction): If a heating is switched on, the heating control checks if the temperature of the heating has risen within 10 subsequent heating cycles. If the temperature of the heating has not risen, the warning “Climate Control” is set and the heating control switches to the following operating status.
Subsequent heating
• If the subsequent heating time is 0, the heating control switches to the operating status “heating”.
• If the subsequent heating time is bigger than 0, the dew points of the heat sink and the mains cabinet will be increased by offsets (parameterisable) and met during the subsequent heating time.
o During subsequent heating, the heating control meets all temperatures and dew points. The cycle time of the subsequent heating is 1 minute. The cycle counter is only reduced if all conditions (temperature and humidity) are met.
o In the end of the subsequent heating time, the heating control switches to the operating status “heating”.
o Premature cancelling of the subsequent heating in the case of a fault: The heating control counts the amount of time in which the system does not meet the conditions for temperature and dew point. If this fault time exceeds an limit value (parameterisable), the warning “Climate Control“ is set and the heating control switches immediately into the operating status “heating”.

30 / 72 9943-1707 - MANUAL - TD OPERATING INSTRUCTIONS - MP1 – ENGLISH
Heating
The following applies for the change into the operating status “heating”:
• The relay “ready for operation” is released.
• The relay for heating operation is switched off.
• The warning “W12: Heating operation active” is confirmed.
In the operating status “heating”, the wind turbine is ready for operation. An excitation release starts the wind turbine.
In operating status “heating”, the heating control operates as in operating status “preheating”. However, the dew points are checked twice per cycle with changeable values (parameterisable).
3.5.2 Subsequent heating time
The subsequent heating time depends on the off duration of the control computer.
• For an off duration of less than 3 hours, no subsequent heating is required.
• For an off duration of more than 3 hours, the subsequent heating time is 1 hour per started off day. The maximum subsequent heating time is 8 hours.
• If the wind turbine is not yet commissioned, the subsequent heating time is 8 hours.
