本願発明の系統連係維持装置は、前記第2の系統連係維持装置において、絶縁型のDC/DCコンバータは、風速計の風速が所定値より大きくなると系統連係インバータへの給電を開始し、風速計の風速が所定値より小さくなると系統連係インバータへの給電を停止することを特徴とする。[0009]
[Means for Solving the Problems]
The grid linkage maintenance device of the present invention is a grid linkage maintenance device of a grid linkage system of a wind power generator and a transmission line, which converts AC power of the transmission line into DC power by AC DC conversion means, and grids the DC power. It is characterized in that power is supplied to the linked inverter.
The system linkage maintenance device according to the present invention is characterized in that, in the above-mentioned system linkage maintenance device, the AC-DC conversion means comprises a rectifying and smoothing circuit and an insulation type DC / DC converter.
System interconnection maintainer of the present invention, in the second system interconnection support systems, insulation type DC / DC converter, and starts to supply power to the system interconnection inverter wind speed anemometer becomes greater than the predetermined value, anemometer Power supply to the grid-connected inverter is stopped when the wind speed of the motor becomes smaller than a predetermined value.

一方系統連係維持装置16は、系統連係インバータ14に並列に接続し、後述する整流・平滑回路と絶縁型のDC/DCコンバータからなる交流直流変換手段によって送電線15の交流電力を直流電力に変換して、系統連係インバータ14へ供給する。
系統連係インバータ14は、系統連係維持装置16から供給される直流電力によって系統連係を維持するから、従来のように系統連係維持用の蓄電池を設ける必要がない。
なお交流直流変換手段は、整流器のみで構成することもできるが、電力の系統連係維持装置16への回り込み等を防止するには、絶縁型のDC/DCコンバータを用いるのが望ましい。[0014]
Meanwhile system interconnection maintaining device 16 is connected in parallel to the system interconnection inverter 14, the AC power transmission line 15 by the AC-DC converter means comprising a DC / DC converter for isolated and rectifying and smoothing circuit to be described later into DC power It converts and supplies to the grid connection inverter 14.
Since the grid connection inverter 14 maintains grid connection by the DC power supplied from the grid connection maintenance device 16, it is not necessary to provide a storage battery for grid connection maintenance as in the prior art.
The AC / DC conversion means can be configured with only a rectifier, but in order to prevent the wraparound of the power to the grid connection maintaining device 16, it is desirable to use an insulation type DC / DC converter.

整流・平滑回路25及び絶縁型のDC/DCコンバータ24は、系統連係維持装置16の交流直流変換手段を構成している。
またA/Dコンバータ26、演算制御回路27、PWM発生回路28等は、CPUと一体的に構成し、外部から設定値を入力するように構成したものを使用できる。[0019]
Rectifying and smoothing circuit 2 5 and the DC / DC converter 2 4 Isolated constitutes the AC-DC converter means system interconnection maintainer 16.
Further, the A / D converter 26, the arithmetic control circuit 27, the PWM generation circuit 28 and the like can be used integrally with the CPU and configured to input the set value from the outside.

整流・平滑回路25は、送電線15の交流電圧(100V又は200V)を直流に変換してDC/DCコンバータ24へ供給する。DC/DCコンバータ24は、整流・平滑回路25から供給される直流電圧を、所定値の直流電圧に変換して、系統連係インバータ14へ供給する。 整流・平滑回路28は、送電線15の交流電圧(100V又は200V)を直流に変換してDC/DCコンバータ24へ供給する。DC/DCコンバータ24は、整流・平滑回路25から供給される直流電圧を、所定値の直流電圧に変換して、系統連係インバータ14へ供給する。[0020]
The rectifying and smoothing circuit 25 converts an alternating voltage (100 V or 200 V) of the transmission line 15 into a direct current and supplies the direct current to the DC / DC converter 24. The DC / DC converter 24 converts the DC voltage supplied from the rectifying and smoothing circuit 25 into a DC voltage of a predetermined value, and supplies the DC voltage to the grid-connected inverter 14. The rectifying and smoothing circuit 28 converts an alternating voltage (100 V or 200 V) of the transmission line 15 into a direct current and supplies the DC / DC converter 24 with the direct current. The DC / DC converter 24 converts the DC voltage supplied from the rectifying and smoothing circuit 25 into a DC voltage of a predetermined value, and supplies the DC voltage to the grid-connected inverter 14.
