摘要
风电机组电网友好型控制是实现风电机组与电网灵活互动的重要途径。通过电压/电流的灵活给定与调节,可令风电机组以有利于电网平衡的方式运行,凸显风电机组的电网友好性特征。因此,该文首先从功能维度、频率维度、时间维度出发,论述风电机组电网友好型控制的典型特征。针对风电机组电压/电流控制方面的需求,分别列举风电机组电网友好型控制在电压协同、电流调控方面的典型策略,以展示电网友好型控制技术的最新研究成果,并预测未来可能的发展动向。
The grid-friendly control strategy has been regarded as a serviceable approach of achieving the flexible interaction between the wind power generators and the power system.By flexibly regulating the voltages/currents,the wind power generators can be controlled to be helpful to the power balance.As a result,the grid-friendly operation of the wind power generator was fulfilled.From the viewpoint of the function dimension,the frequency dimension and the time dimension,the typical characteristics of the grid-friendly control strategies for wind power generators were presented.Then,in order to present the lasted progress in the grid-friendly control strategies,the control strategies on the voltage coordination and the current regulation were reviewed and compared.Finally,the possible future development of the grid-friendly control strategies was discussed.
