| Abstract: | Aiming at demerits of signal processing being excessively concentrated and easy to be interfered of the common centralized control system of doubly fed wind power converter, this paper designs a kind of distributed control system which is able to improve anti-interference capability. It introduces overall architecture of the distributed control system, function of each distributed unit, communication protocol and rotor side and grid side distributed control strategies. Meanwhile, it analyzes reasons for enhancing anti-interference capability. In addition, it provides main circuit topology structure of the converter and introduces long-term operation testing for the converter. The result verifies reliability and performance of the converter and control system. Meanwhile, it provides part of ooerational waves |
