The monitoring of the DC link of split type wind turbine converter system |
| abstract |
A method of monitoring split type wind turbine converter system, the split type wind turbine converter system has at least one generator-side converter and at least one grid side converter and DC link that off-site location is arranged in, and the form of the DC link is that the slender conductor at least one positive conductor and at least one negative conductor constructs.The impedance of DC link conductor configuration is determined by means of direct current voltage sensor.Voltage between positive conductor and negative conductor determines at generator-side converter and at grid side converter, and the difference between voltage is determined.The impedance of DC link conductor configuration is by determining the voltage difference determined is with the DC current for flowing through DC link conductor configuration associated.If impedance is more than given impedance threshold, malfunction is identified. |
