摘要(Abstract):
电网电压过高、变压器选择不合理、励磁装置励磁方式不合理及就地无功补偿容量严重不足是造成小水电无功出力不足的主要原因。针对小水电的运行特点,提出了小水电密集地区的无功平衡策略及方法。
The insufficient reactive power output of small hydropower is mainly resulted from the overhigh grid voltage,unreasonable selection of the transformer,inappropriate excitation mode of the excitation device and severely deficient local reactive power compensation.Based on the operational characteristics of small hydropower,this paper puts forward the strategy and method of reactive power balance in dense areas of small hydropower plants.
