摘要
当前风电场的有功功率控制分配策略多采用平均分配的方式,若风电场各机组的风速差异较大,很可能导致整个风电场的有功功率输出与网调指令存在较大的差距。对此,综合协调考虑风电机组的控制特性及其当前的平均有功功率、平均风速和运行状态等信息,提出一种新的有功功率指令分配策略,有效减小了风电场功率输出与网调指令值的差距,最大限度地减小限功率对业主造成的损失。
Currently, average distribution is generally adopted for the active power control instruction of wind farms. If the wind speed differs much among wind turbines in the wind farm, the output active power of the wind farm may as well differ much from the instruction of the electricity grid. For this reason, a new distribution strategy of active power instruction is proposed by integrated consideration on parameters of each wind turbine, including control characteristics, average active power, average wind speed and operating state. This new strategy can effectively reduce the difference between the wind farm output active power and the grid instruction, so as to reduce the loss of wind farm owner due to active power restriction to the possible extent.
