An Integrated Frequency Control for Grid-connected Wind Farm Based on VSC-HVDC
针对采用柔性直流输电并网方式(VSC-HVDC)的风电场两侧交流系统解耦特性,无法采用传统控制方式调频问题,结合风电机组虚拟惯性控制和下垂控制,以及直流电容快速充放电原理,在VSC-HVDC的网侧变流器增加变直流电压控制环节,提出一种改变直流母线电压并以此作为风电机组调频信号的综合调频控制方式.当电网因功率不平衡而发生频率波动时,VSC-HVDC直流电压能随之改变,快速释放或者吸收直流电容中存储部分的电能,再将电压值作为调频信号传递给风电场,使风…查看全部>>
As to the frequency decoupling characteristics of AC system at the two sides of wind farm by using grid-connected mode of voltage source converter based high voltage direct current(VSC-HVDC),the frequency can not be regulated by traditional control method By combing virtual inertial control,droop control and quick charging and discharging theory of DC capacity,an integrated frequency control is proposed for varying DC voltage control unit added on inverter a…查看全部>>
