- FIG. 2 shows the configuration of the power converter 204.
- the power converter 204 includes a converter 2042 that converts AC power generated by the permanent magnet rotary generator 201 into DC power, and DC power that is disposed on the power system side of the converter 2042 and converted by the converter 2042 for commercial use. It has an inverter 2041 for converting into AC power having a frequency, and a smoothing capacitor 2043 arranged between the inverter 2041 and the converter 2042. Each inverter and converter is composed of six switching elements.
- the power converter 204 converts the frequency and waveform into an appropriate (high quality) frequency when transmitting power to the power system 10.
- the LC filter 214 includes two coils 215 and a capacitor 216 disposed between the two coils 215, and suppresses harmonics output from the power converter 204 to the power system 10 side.
- the control by the auxiliary machine 206 during the wind turbine power generation operation will be described.
- the windmill performs a power generation operation when the wind speed is higher (or higher) than the cut-in speed and lower (or lower) than the cut-out wind speed during a storm.
- the specifications for cut-in speed and cut-out speed differ depending on the model.
- a permanent magnet type rotary generator 201 is used as a generator, and power is generated by the rotation of the rotor 202 even without an exciting current.

- the alternating current applied to the diode bridge 207 is rectified and converted to direct current power.
- the control power source 208 of the control device 209 is provided.
- the reason why DC power is used for the control power supply 208 is that ICs such as a microcomputer, a memory, and an FPGA on the control board included in the control device do not operate unless they are DC.
- AC power generated by the permanent magnet type rotary generator 201 is applied to the power converter 210.
- an appropriate power waveform and The frequency can be converted and supplied to the auxiliary machine 206 and the wind turbine control device 203.
- Auxiliary machine 206 receives power supply from power converter 210 and issues a command to windmill control device 203 to perform pitch angle control and yaw control of rotor 202 according to the wind speed and direction.
- the generated power during the power generation operation of the windmill is transmitted from the permanent magnet rotary generator 201 to the power system 10 via the power converter 204.
- the converter 2042 and the inverter 2041 in the power converter 204 convert the power into a power whose quality is ensured, and further filter the harmonic noise generated from the power converter 204 by the LC filter 214, thereby further increasing the power. Quality can be improved.
- the circuit breaker 212 is provided to prevent the accident from spreading when an accident or the like occurs.
- the generated power with improved power quality is transformed to a high voltage for the power system 10 by the step-up transformer 3.
- the auxiliary power source 205 for controlling the wind turbine is covered by the power generated by the permanent magnet rotary generator 201, the control by the auxiliary device 206, that is, the wind turbine is used regardless of the state of the power system 10. Overall control can be performed. That is, even if the system voltage of the power system is lowered, it is not necessary to switch the circuit during normal power generation operation.
- Example 2 will be described with reference to FIG. In addition, description is abbreviate
- the auxiliary power source 205 is directly connected to the permanent magnet rotary generator 201.
- the auxiliary power source 225 is a DC current region between the converter 2042 and the inverter 2041 in the power converter 204. Is connected.
- the diode 2042 converts the generated power from AC power to DC power even if the converter 2042 does not perform a switching operation. Therefore, the diode bridge 207 for converting the generated power required in the first embodiment from an alternating current to a direct current is not necessary. This provides a simplified structure.
- the power converter 226 disposed in the auxiliary machine power source 225 only needs to convert direct current into alternating current, and is half the role compared to the first embodiment, and the configuration is simplified.
- auxiliary power source 225 for controlling the wind turbine is covered by the power generated by the permanent magnet rotary generator 201, the control by the auxiliary device 206, that is, the entire wind turbine is controlled regardless of the state of the power system 10. Can be controlled.
- Example 3 will be described with reference to FIG. In addition, description is abbreviate
- a secondary excitation generator 230 is provided in place of the permanent magnet rotary generator 201, and a permanent magnet rotary generator 232 is provided as an auxiliary generator in the rotor 233.
- the power conversion device 304 is connected to the power system 10, a converter 3041 that converts AC power into DC power, and AC power for appropriately controlling the output frequency and power factor of the secondary excitation generator 230 with DC power. Is connected to the rotor of the secondary excitation generator 230 via a slip ring.
- the stator of the secondary excitation generator 230 outputs the generated power to the power system 10 via the circuit breaker.
- the same control power source as the auxiliary power source 205 in the first embodiment is used for connection to the permanent magnet type rotary generator 232. Needless to say, this change can be made even when the permanent magnet type rotary generator 201 is used as the main generator as in the first embodiment.
- auxiliary power source 205 for controlling the wind turbine is covered by the power generated by the permanent magnet type rotary generator 232, the control by the auxiliary device 206, that is, the entire wind turbine is controlled regardless of the state of the power system 10. Can be controlled.
- the auxiliary power supply is covered by the power generated from the permanent magnet type rotary generator. If it is a permanent magnet type rotary generator, it does not require excitation power (especially the point that excitation power is not required at startup is effective for independent operation from the power system) and starts rotation. This makes it possible to drive the auxiliary machine without relying on the state of the power system and to control the wind turbine.
- a downwind type windmill that performs power generation operation with the rotor facing downwind on the windmill. If it is a downwind type windmill, even if it does not perform yaw control (so-called free yaw control), the rotor will naturally face downwind like a weathercock, and it is possible to shift to a position suitable for power generation operation. Therefore, it is possible to shift to a state where the rotor can rotate without a control power supply. Furthermore, as long as the rotor rotates, the permanent magnet type rotary generator can start the power generation operation as described above. Therefore, by using both together, the excitation power is not required for restarting the windmill. It is possible to restart from a state where there is no power supply or excitation power from the power system.
- This point is particularly beneficial when it is installed in an area where the power network is not yet developed, or when the power network is interrupted due to a disaster or the like.
