摘　　要：从理论上分析了WT1500型风电机组的无功功率发生能力,并搭建了实时以太网(EtherCAT)和多种现场总线为调度网络的无功功率发生试验平台;提出了无功功率控制的整体技术方案,并通过PLC程序进行控制与实现。以背靠背功率试验台为基础,对其无功发生能力进行了试验,试验证明了理论分析的正确性及控制方案的可行性。The reactive power generation capability of WT1500 wind turbine is theoretically analyzed. The network of reactive power testing platform is installed by composing of EtherCAT and multi-field bus. In this paper, the overall technical program of reactive power control is proposed, and which is controlled and realized by PLC program, and the reactive power generation capability is tested in workshop based on back to back power testing platform. The experiments prove correction of the theoretical analysis and feasibility of the control scheme.
