| 摘 要： | 我国风电场内无功补偿的方式是在风电场汇集站内装设集中无功补偿装置,这造成风电场无功补偿的投资很大。文章结合工程实例,通过对不同发电量下风电场的无功损耗和电压波动情况进行计算,提出利用风力发电机的无功功率可基本实现风电场的无功平衡,风电场母线电压的变化是无功补偿设备选型的依据,对于发电量变化引起的母线电压变化不超出电网要求的风电场,应利用风力发电机的无功功率减小汇集站内无功补偿装置的容量,降低无功补偿的投资。

| Abstract: | At present, the manner of reactive power compensation inside wind farms in China is to configure centralized reactive power compensators in wind farm collection stations, however such a compensation manner leads to high investment.Based on engineering example, by means of computing reactive power loss and voltage fluctuation of wind farm under various energy generation, it is pointed out that the reactive power balance of wind farm can be implemented by utilizing reactive power of wind turbine generators.Th... |
