【摘要】 直接功率控制、下垂控制是目前应用较多的逆变器控制策略,也有控制方法提出将无功与电压、有功与频率同时进行控制。为了分析逆变器进行多个目标同时控制时的运行能力,本文通过推导逆变器输出功率公式得出无功与电压、有功与频率之间存在关联性,通过分析下垂控制过程得出有功功率与系统频率间的约束关系,并搭建simulink模型验证了逆变器在进行控制目标选取时具有一定的矛盾性。更多还原

【Abstract】 Direct power control and droop control are currently used in many inverter control strategies. There are also control methods that control reactive power and voltage, active power, and frequency simultaneously. This paper derives the correlation between reactive power and voltage, active power and frequency by deriving the output power formula of the inverter. By analyzing the droop control process, the constraint relationship between active power and system frequency is obtained, and a simulink model is established to verify the inversion. There are certain contradictions in the multi-objective control.更多还原
